What are the protective equipment requirements?

• The kind of clothing should be appropriate, i.e., it should be tight-fitting but not be a hindrance.
• Do not wear jewelry or clothing which could become entangled with bushes or shrubs.
• If you have long hair, always wear a hairnet!
• It is necessary to wear a protective helmet whenever working with the chain saw.
• The protective helmet is to be checked at regular intervals for damage and is to be replaced after 5 years at the latest.
• Use only approved protective helmets.
• The face shield of the protective helmet (or the goggles) protects against sawdust and wood chips.
• During operation of the chain saw always wear a goggle or a face shield to prevent eye injuries.
• Safety shoes equipped with a protective layer provide protection against cuts and ensure a secure footing.

What are the fuel and refueling precautions?

• Stop the engine before refuelling the chain saw.
• Do not smoke or work near open fires.
• Let the engine cool down before refuelling.
• Fuels can contain substances similar to solvents. Eyes and skin should not come in contact with mineral oil products.
• Always wear protective gloves when refuelling.
• Frequently clean and change protective clothes.
• Do not breathe in fuel vapors. Inhalation of fuel vapors can be hazardous to your health.
• Do not spill fuel or chain oil. When you have spilt fuel or oil immediately clean the chain saw. Fuel should not come in contact with clothes. If your clothes have come in contact with fuel, change them at once.
• Ensure that no fuel or chain oil oozes into the soil (environmental protection). Use an appropriate base.
• Refuelling is not allowed in closed rooms. Fuel vapors will accumulate near the floor (explosion hazard).
• Ensure to firmly tighten the screw plugs of the fuel and oil tanks.
• Change the place before starting the engine (at least 3 m from the place of refuelling).
• Fuel cannot be stored for an unlimited period of time. Buy only as much as will be consumed in the near future.
• Use only approved and marked containers for the transport and storage of fuel and chain oil. Ensure children have no access to fuel or chain oil.

What are the steps for putting the chain saw into operation?

• Do not work on your own. Another person must be nearby in case of emergencies (within shouting distance).
• Ensure that there are no children or other people within the working area. Pay attention to any animals in the working area as well.
• Before starting work the chain saw must be checked for perfect function and operating safety according to the prescriptions.
• Put the chain saw only into operation if it is completely assembled. Never use the chain saw when it is not completely assembled.
• Before starting the chain saw ensure that you have a safe footing.
• Put the chain saw into operation only as described in this instruction manual. Other starting methods are not allowed.
• When starting the chain saw it must be well supported and securely held. The guide bar and chain must not be in contact with any object.

What should you check before starting work?

Check especially the function of the chain brake, the correct mounting of the guide bar, the correct sharpening and tightening of the chain, the firm mounting of the sprocket guard, the easy motion of the throttle lever and the function of the throttle lever lock, the cleanliness and dryness of the handles, and the function of the ON/OFF switch.

How should the chain saw be held when in operation?

When working with the chain saw always hold it with both hands. Take the back handle with the right hand and the tubular handle with the left hand. Hold the handles tightly with your thumbs facing your fingers.

What will happen when you release the throttle lever?

The chain will keep on running for a short period of time (free-wheeling).

What safety measures should be followed when operating the chain saw?

• Continuously ensure that you have a safe footing.
• Hold the chain saw such that you will not breathe in the exhaust gas. Do not work in closed rooms (danger of poisoning).
• Switch off the chain saw immediately if you observe any changes in its operating behavior.
• The engine must be switched off before checking the chain tension, tightening the chain, replacing it or clearing malfunctions.

What should you do when the sawing device is hit by stones, nails or other hard objects?

Switch off the engine immediately and check the sawing device.

What should you do when stopping work or leaving the working place?

Switch off the chain saw and put it down such that nobody is endangered.

Why shouldn’t you put the overheated power chain saw in dry grass or on any inflammable objects?

The muffler is very hot and it could cause a fire.

What can happen if oil dropping from the chain or guide bar after having stopped the saw chain comes in contact with soil?

It will pollute the soil. Always use an appropriate base.

What is kickback?

Kickback occurs when the upper part of the end of the guide bar inadvertently touches wood or other hard objects. This causes the saw to be thrown back toward the user with great force and out of control, which could cause injury.

How can you prevent kickback?

• Only specially-trained persons should perform plunge cuts, i.e. piercing timber or wood with the tip of the saw!
• Never apply the end of the bar when starting to make a cut.
• Always observe the end of the guide bar. Be careful when continuing an already started cut.
• When starting to cut the chain must be running.
• Ensure that the chain is always sharpened correctly. Pay special attention to the height of the depth limiter.
• Never cut several branches at the same time. When cutting a branch ensure that no other branch is touched.
• When crosscutting a trunk be aware of the trunks next to it.

What working behavior/method of working precautions should be taken?

• Only use the chain saw during good light and visibility periods. Be aware of slippery or wet areas, and of ice and snow (risk of slipping). The risk of slipping is extremely high when working on recently peeled wood (bark).
• Never work on unstable surfaces. Make sure that there are no obstacles in the working area, risk of stumbling. Always ensure that you have a safe footing.
• Never saw above your shoulder height.
• Never saw while standing on a ladder.
• Never climb up into trees to perform sawing with the chain saw.
• Do not work leaning too far over.
• Guide the chain saw in such a way that no part of your body is within the elongated swivelling range of the saw.
• Use the chain saw for sawing wood only.
• Avoid touching the ground with the chain saw while it is still running.
• Never use the chain saw for lifting up or removing pieces of wood or other objects.
• Remove foreign objects such as sand, stones and nails found within the working area. Foreign objects may damage the sawing device and can cause dangerous kickback.
• When sawing precut timber use a safe support (sawing jack). Do not steady the workpiece with your foot, and do not allow anyone else to hold or steady it.
• Secure round pieces against rotation.
• For cutting down trees or performing crosscuts the spike bar must be applied to the wood to be cut.
• Before performing a crosscut firmly apply the spike bar to the timber, only then can the timber be cut with the chain running. For this the chain saw is lifted at the back handle and guided with the tubular handle. The spike bar serves as a center of rotation. Continue by slightly pressing down the tubular handle and simultaneously pulling back the chain saw. Apply the spike bar a little bit deeper and once again lift the back handle.

What is the recommendation for piercing timber?

It is urgently recommended to have this carried out by specially trained persons only, as there is a high risk of kickback.

How should longitudinal cuts be performed?

Do longitudinal – lengthwise – cuts at the lowest possible angle. Be very careful when doing this type of cut, as the spike bar cannot grip.

When must the saw be running?

Whenever you remove the chain saw from the wood.

What should be done with the throttle lever when performing several cuts?

The throttle lever must be released in between cuts. If the chain is still running when carrying the chain saw the guide bar protection cover must be applied or the chain brake must be actuated.

Why should the chain saw be guided with the lower edge of the bar?

When cutting with the upper edge of the guide bar, the chain saw may be pushed in the direction of the user if the chain gets clamped. If you use the lower edge of the bar the chain saw will then be pushed away from you.

How should you cut timber that is under tension?

First cut the pressure side. Then the crosscut can be performed on the tension side. Thus clamping of the guide bar can be avoided.

Who should fell trees or cut off branches?

People felling trees or cutting of branches must be specially trained as there is a high risk of injuries!

What precautions should be taken when cutting branches?

• When cutting off branches, the chain saw should be supported on the trunk.
• Do not use the end of the bar for cutting (risk of kickback).
• Be aware of branches under tension.
• Do not cut free branches from below.
• Never perform detensioning cuts while standing on the trunk.

What precautions should be taken before cutting down a tree?

Before cutting down a tree ensure that:

• Only those people are within the working area which are actually involved in cutting down the tree.
• Every worker involved can withdraw without stumbling (the people should withdraw backward in a diagonal line, i.e. at a degree of 45°).
• The bottom part of the trunk is free from foreign objects, underbrush and branches. Make sure to have a safe footing (risk of stumbling).
• The next working place is at least 2 1/2 tree lengths away. Before cutting down the tree check the direction of fall and make sure that there are neither people nor objects within a distance of 2 1/2 tree lengths.

What should be considered when judging a tree?

• Direction of hanging
• Loose or dry branches
• Height of the tree
• Natural overhang
• Is the tree rotten?
• Take into account the direction and speed of the wind. If strong gusts are occurring, do not do any felling.

What is the process of cutting the roots of a tree?

Start with the strongest root. First do the vertical and then the horizontal cut.

What is the purpose of notching the trunk?

The notch determines the direction of fall and guides the tree. The trunk is notched perpendicular to the direction of fall and penetrates 1/3 -1/5 of the trunk diameter. Perform the cut near the ground.

How should the cut be corrected?

Always correct the cut over the whole width of the notch.

How should you cut down a tree?

Cut down the tree above the bottom edge of the notch. The cut must be exactly horizontal. The distance between both cuts must be approx. 1/10 of the trunk diameter. The material between both cuts serves as a hinge. Never cut it through, otherwise the tree will fall without any control. Insert felling wedges in time.

What should be used to secure the cut?

Secure the cut only with wedges made of plastic or aluminum. Do not use iron wedges. If the saw hits an iron wedge the chain can be seriously damaged or torn.

What precautions should be taken when cutting down a tree?

• When cutting down a tree always stay sideways of the falling tree.
• When withdrawing after having performed the cut, be alert for falling branches.
• When working on sloping ground the user of the chain saw must stay above or sideways of the trunk to be cut or the tree already cut down.

What are the dangers of vibration during operation?

Individuals with poor circulation who are exposed to excessive vibration may experience injury to blood vessels or the nervous system. Vibration may cause the following symptoms to occur in the fingers, hands or wrists: “Falling asleep” (numbness), tingling, pain, stabbing sensation, alteration of skin color or of the skin.

What should you do if you experience any of the symptoms caused by vibration?

See a physician.

How can the risk of vibration white finger be reduced?

Keep your hands warm, wear gloves, and make sure the saw chain is sharp.

What are the safety measures for service and transport?

• When changing your location during work switch off the chain saw and actuate the chain brake in order to prevent an inadvertent start of the chain.
• Never carry or transport the chain saw with the chain running.

What are the precautions when storing the chain saw?

• When the saw is hot, do not cover it (with a tarp, blanket, newspaper or the like).
• Let the saw cool down before putting it in a storage case or vehicle. Saws with catalytic converter take longer to cool down!
• When transporting the chain saw over long distances the guide bar protection cover (delivered with the chain saw) must be applied.
• Carry the chain saw with the tubular handle. The guide bar points backwards. Avoid coming in contact with the muffler (danger of burns).
• Ensure safe positioning of the chain saw during car transportation to avoid fuel or chain oil leakage.
• Store the chain saw safely in a dry place. It must not be stored outdoors. Keep the chain saw away from children.
• Before storing the chain saw over a long period of time or shipping it the fuel and oil tanks must be completely emptied.

What maintenance steps should be taken?

• Before performing maintenance work switch off the chain saw and pull out the plug cap.
• Before starting work always check the operating safety of the chain saw, in particular the function of the chain brake. Make sure that the chain is always sharpened and tightened correctly.
• Operate the chain saw only at a low noise and emission level. For this ensure the carburetor is adjusted correctly.
• Regularly clean the chain saw.
• Regularly check the tank cap for tightness.

What are the additional maintenance safety recommendations?

• Observe the accident prevention instructions issued by trade associations and insurance companies.
• Do not perform any modifications on the chain saw. You will put your safety at risk.
• Perform only the maintenance and repair works described in the instruction manual. All other work must be carried out by Makita Service.
• Use only original Makita spare parts and accessories.
• Using spare parts other than original Makita parts or accessories and guide bar/chain combinations or lengths which are not approved bring a high risk of accidents. We cannot accept any responsibility for accidents and damage resulting from using sawing devices or accessories which have not been approved.

What should you do in case of an accident?

For the event of a possible accident, please make sure that a first aid kit is always immediately available close by. Immediately replace any items used from the first aid box.

What information should you give when calling for help in case of an accident?

• Place of the accident
• What happened
• Number of injured people
• Kind of injuries
• Your name

What is the packaging made of?

Your Makita chain saw comes delivered in a protective cardboard box to protect against shipping damage.

Can the packaging be reused?

Cardboard is a basic raw material and is consequently reuseable or suitable for recycling (waste paper recycling).

What are the fuels that can be used?

Only use unleaded regular-grade petrol. The addition of oil is required for lubricating the engine. Two-stroke engine oil of good quality for air-cooled engines must be added to the petrol at a ratio of 50 : 1. When using Makita two-stroke oil HP-100 the mixing ratio can be 100 : 1. When using Aspen alkylate fuel the mixing ratio is 50 : 1 (2 %). The use of Aspen alkylate fuel is strongly recommended, as it is free from harmful components and causes less harm to the environment. Moreover, emissions are reduced and operation is improved (less deposit formation in the combustion chamber). In addition, the odour nuisance is signiÞ cantly lower than with regular petrol. When using other two-stroke oil brands we recommend a mixing ratio of 50 : 1.

What is the recommended quality grade for two-stroke oils?

JASO FC or ISO EGD

What are the cautions for using fuels and oils?

The correct composition of the fuel is of utmost importance for the function and service life of the engine.

Never use neat petrol without oil. This will damage the engine.

Do not use fuel which has been stored for an unlimited period of time. This can lead to operating malfunctions.

Do not mix fuel in the fuel tank of the saw.

Ensure to always use fresh fuel.

How do you refuel?

Put the chain saw down on a safe, level and clean surface (danger of fire!). Clean the area around the fuel tank lid to avoid contaminating the fuel with dirt. Carefully unscrew the fuel tank cap (20) and fill up with the fuel/oil mixture. Ensure that no fuel is spilt.

Carefully screw on the fuel tank cap (20) again and wipe off any spilt fuel.

How do you check chain lubrication?

Hold the chain saw over a light coloured surface or a piece of paper. Let the engine run at medium speed for approx. 30 seconds (A). If a clear oil trace is visible (B) the lubrication system functions properly.

How do you adjust chain lubrication?

Use a round file (diameter 4,0 mm) with holder for sharpening the saw chain.

Place the file onto the cutting edge (A) and push it forward with even pressure. Lift the file from the cutting edge during the return stroke. Always maintain the same file angle for each tooth.

The angle for the top plate cutting angle is 35°.

The angle for the side plate cutting angle is 80° or 60°.

First sharpen all cutting teeth on one side. Then turn the chain saw and sharpen the cutting teeth on the other side.

The depth limiter (B) determines how deeply the cutting teeth penetrate into the wood. For this reason it must be filed down to the correct height after every second sharpening of the cutting teeth.

Place the depth gauge © onto the chain.

File down the protruding depth limiter (B) with a flat file.

How do you clean the inside of the sprocket guard?

Sawdust will accumulate in the inside of the sprocket guard (11). Clean the inside of the sprocket guard (11) with a screwdriver or a similar tool after approx. 5 operating hours.

How do you clean the guide bar?

Clean the groove of the guide bar (25) regularly from sawdust and resin. The chain oil will then reach the saw chain constantly and ensure good lubrication. If the guide bar (25) is very dirty the chain oil flow can be obstructed, which will lead to overheating and damage to the guide bar (25) and the saw chain (24).

Turn the guide bar (25) from time to time. Thus its service life can be increased considerably.

Check the chain tension frequently – new chains tend to get longer during use! When checking the chain tension the engine must be switched off.

NOTE: It is recommended to use 2-3 chains alternatively. In order to guarantee uniform wear of the guide bar the bar should be turned over whenever replacing the chain.

How do you retension the saw chain on models with quick tensioner on sprocket guard (TLC)?

All that is necessary to retension the saw chain is to loosen the quick tensioner slightly as described under “Mounting the guide bar and saw chain”. Tension the chain as already described.

How do you engage the chain break (braking)?

If the kickback is strong enough the sudden acceleration of the guide bar combined with the inertia of the hand guard will automatically actuate the chain brake. To engage the chain brake manually, simply push the hand guard forward (towards the tip of the saw) with your left hand (arrow 1).

How do you release the chain break?

Pull the hand guard towards you (arrow 2) until you feel it catch. The brake is now released.

What is the purpose of the chain break?

The (EA3500S-EA3503S) comes with an inertia chain brake as standard equipment. If kickback occurs due to contact of the guide-bar tip with wood (see SAFETY PRECAUTIONS), the chain brake will stop the chain through inertia if the kickback is sufficiently strong. The chain will stop within a fraction of a second. The chain brake is installed to block the saw chain before starting it and to stop it immediately in case of an emergency.

IMPORTANT: NEVER run the saw with the chain brake activated (except for testing, see “Testing chain brake”)! Doing so can very quickly cause extensive engine damage! ALWAYS release the chain brake before starting the work!

What kind of oil should you use for lubricating the chain and guide bar?

Use an oil with adhesive additive for lubricating the chain and guide bar. The adhesive additive prevents the oil from being flung off the chain too quickly. (The PDF) recommends the use of chain oil which is bio-degradable in order to protect the environment. The use of bio-degradable oil may even be required by local regulations. The chain oil BIOTOP sold by MAKITA is made of special vegetable oils and is 100% bio-degradable. BIOTOP has been granted the “blue angel” (Blauer Umweltschutz-Engel) for being particularly environment-friendly (RAL UZ 48).

What are the available sizes for BIOTOP chain oil?

• 1 l
• 5 l

How long is bio-degradable oil stable?

Bio-degradable oil is stable only for a limited period of time. It should be used within 2 years from the date of manufacture (printed on the container).

What powers the chain saw?

CAUTION: This saw is powered by mineral-oil products (gasoline and oil). Be especially careful when handling gasoline. Do not smoke. Keep tool well away from open flames, sparks, or fire (explosion hazard).

What is the correct fuel mixture for the chain saw?

This tool is powered by a high-performance air-cooled two-stroke engine. It runs on a mixture of gasoline and two-stroke engine oil. The engine is designed for unleaded regular gasoline with a min. octane value of 91 ROZ. In case no such fuel is available, you can use fuel with a higher octane value. This will not affect the engine. In order to obtain an optimum engine output and to protect your health and the environment use unleaded fuel only. To lubricate the engine, use a synthetic oil for two-stroke air-cooled engines (quality grade JASO FC or ISO EGD), which has to be added to the fuel. The engine has been designed for use of MAKITA high-performance two-stroke engine oil and a mixture ratio of only 50:1 to protect the environment. In addition, a long service life and reliable operation with a minimum emission of exhaust gases are ensured.

What are the available sizes for MAKITA high-performance two-stroke engine oil?

• 1 l
• 100 ml

What is the recommended mixture ratio if MAKITA high-performance two-stroke engine oil is not available?

In case MAKITA high-performance two-stroke engine oil is not available, it is urgently recommended to use a mixture ratio of 50:1 with other two-stroke engine oils, as otherwise optimum operation of the engine cannot be guaranteed.

Can you use ready-mixed fuel from petrol stations?

Caution: Do not use ready-mixed fuel from petrol stations.

What is the correct mixture ratio for the chain saw?

• 50:1 when using MAKITA high-performance two-stroke engine oil, i.e. mix 50 parts gasoline with 1 part oil.
• 50:1 when using other synthetic two-stroke engine oils (quality grade JASO FC or ISO EGD), i.e. mix 50 parts gasoline with 1 part oil.

How do you prepare the fuel-oil mixture?

NOTE: For preparing the fuel-oil mixture first mix the entire oil quantity with half of the fuel required, then add the remaining fuel. Thoroughly shake the mixture before filling it into the chain saw tank.

Why should you not add more engine oil than specified?

It is not wise to add more engine oil than specified to ensure safe operation. This will only result in a higher production of combustion residues which will pollute the environment and clog the exhaust channel in the cylinder as well as the muffler. In addition, fuel consumption will rise and performance will decrease.

What is the storage life of fuels?

Fuels have a limited storage life. Fuel and fuel mixtures age through evaporation, especially at high temperatures. Aged fuel and fuel mixtures can cause starting problems and damage the engine. Purchase only that amount of fuel, which will be consumed over the next few months. At high temperatures, once fuel has been mixed it should be used up in 6-8 weeks.

Where should you store fuel?

Store fuel only in proper containers, in dry, cool, secure locations!

What are the dangers of skin and eye contact with mineral oil products?

AVOID SKIN AND EYE CONTACT

Mineral oil products degrease your skin. If your skin comes in contact with these substances repeatedly and for an extended period of time, it will desiccate. Various skin deseases may result. In addition, allergic reactions are known to occur. Eyes can be irritated by contact with oil. If oil comes into your eyes, immediately wash them with clear water. If your eyes are still irritated, see a doctor immediately!

What is the correct mixture ratio in cm3 for gasoline and oil?

Gasoline	MAKITA high-performance two-stroke engine oil	Other synthetic two-stroke engine oils (quality grade JASO FC or ISO EGD)
1000 cm3 (1 litre)	20 cm3	20 cm3
5000 cm3 (5 litres)	100 cm3	100 cm3
10000 cm3 (10 litres)	200 cm3	200 cm3

How do you refuel the chain saw?

FOLLOW THE SAFETY PRECAUTIONS!

Be careful and cautious when handling fuels.

1. The engine must be switched off!
2. Thoroughly clean the area around the caps, to prevent dirt from getting into the fuel or oil tank.
3. Unscrew the tank cap (use the universal wrench if necessary, see illustration) and fill the tank with fuel mixture or saw chain oil up to the bottom edge of the filling neck. Be careful not to spill fuel or chain oil!
4. Screw on the tank cap by hand all the way.
5. Clean the tank cap and the area around the tank after refuelling.

How do you lubricate the chain?

During operation there must always be sufficient chain oil in the chain-oil tank to provide good chain lubrication. At medium oil feed rate, the oil tank holds enough for one fuel tank’s worth of operation. During this procedure, check whether there is enough chain oil in the tank and refill if necessary. Do this only with the engine turned off! Screw on the tank cap by hand all the way.

Why should you never use waste oil?

NEVER USE WASTE OIL

Waste oil is very dangerous for the environment. Waste oil contains high amounts of carcinogenic substances. Residues in waste oil result in a high degree of wear and tear at the oil pump and the sawing device. In case of damage caused by using waste oil or unappropriate chain oil the product guarantee will be null and void. Your salesman will inform you about the use of chain oil.

What are the dangers of skin and eye contact with mineral oil products?

AVOID SKIN AND EYE CONTACT

Mineral oil products degrease your skin. If your skin comes in contact with these substances repeatedly and for an extended period of time, it will desiccate. Various skin deseases may result. In addition, allergic reactions are known to occur. Eyes can be irritated by contact with oil. If oil comes into your eyes, immediately wash them with clear water. If your eyes are still irritated, see a doctor immediately!

What is an important note regarding bio-degradable chain oils?

If you are not planning to use the saw again for an extended period of time, empty the oil tank and put in a small amount of regular engine oil (SAE 30), and then run the saw for a time. This is necessary to flush out all remaining bio-degradable oil from the oil tank, oil-feed system, chain and guide bar, as many such oils tend to leave sticky residues over time, which can cause damage to the oil pump or other parts. The next time you use the saw, fill the tank with BIOTOP chain oil again. In case of damage caused by using waste oil or inappropriate chain oil the product guarantee will be null and void. Your salesman will inform you about the use of chain oil.

How do you check the chain lubrication?

Never work with the chain saw without sufficient chain lubrication. Otherwise the service life of the chain and guide bar will be reduced. Before starting work check the oil level in the tank and the oil feed.

Check the oil feed rate as described below:

• Start the chain saw (see “Starting the engine”).
• Hold the running chain saw approx. 15 cm above a trunk or the ground (use an appropriate base).
• If the lubrication is sufficient, you will see a light oil trace because oil will be flung off the chain. Pay attention to the direction the wind is blowing and avoid unnecessary exposure to the oil spray!

Is it normal for residual chain oil to drip from the oil feed system, the guide bar and the chain after the saw has been turned off?

Yes, this does not constitute a defect.

How do you ensure troublefree operation of the oil pump?

To ensure trouble-free operation of the oil pump the oil guide groove at the crank case and the oil inlet bore in the guide bar must be cleaned regularly.

How do you adjust the chain lubrication?

The engine must be switched off. You can adjust the oil pump feed rate with the adjusting screw on the bottom side of the housing. The oil pump is factory-set to the minimum feed rate. Two settings are possible – minimum and maximum feed rate.

To adjust the supply rate, use a small screwdriver to turn the adjusting screw:

• to the right for a faster oil feed rate.
• to the left for a slower oil feed rate.

Select one of the two settings, depending on the guide bar length.

What should you do while working with the chain saw?

While working make sure there is enough chain oil in the tank. If necessary, add oil.

How do you start the engine?

Do not start the chain saw until after it is completely assembled and checked! Move at least 3 meters / 10 feet away from the place where the chain saw was fueled. Make sure you have a secure footing, and place the saw on the ground in such a way that the guide bar and chain are not near anything. Actuate the chain brake (block it). Hold the front handle firmly with one hand and press the saw against the ground. Hold the down rear handguard with your right foot as shown.

How does the Featherlight-Start system work?

The Featherlight-Start System lets you start the saw without effort. Go through the starting procedure smoothly and evenly.

How do you cold start the chain saw?

• Prime the fuel pump by pressing it several times until you can see fuel in the pump.
• Move the combination switch up (choke position). This also actuates the half-throttle lock.
• Pull the starter handle smoothly and evenly.
• CAUTION: Do not pull the starter cable more than about 50 cm/20" out, and let it back in slowly by hand.
• Repeat the starting procedure twice.

What do you do once the chain saw is running?

Move the combination switch to the central “ON” position. Pull the starter handle smoothly and evenly again. As soon as the engine is running, grasp the rear handle (the safety lock button is actuated by the palm of the hand) and press the throttle trigger.

CAUTION: The engine must be put in idle immediately after starting. If this is not done, the clutch can be damaged. Now disengage the chain brake.

How do you warm start the chain saw?

As described above for cold starting, but before starting push the combination switch up (Choke position) and then right away back to the middle “ON” position. This is only to engage the half-throttle lock. If the engine doesn’t start after 2 or 3 pulls, repeat the entire starting procedure as described for cold starting.

NOTE: If the engine was switched off only for a short time, the saw can be started without using the combination switch.

What should you do if the fuel tank has been completely emptied and the engine has stopped due to lack of fuel?

Prime the fuel pump by pressing it several times until you can see fuel in the pump.

How do you stop the engine?

Depress the combination switch.

NOTE: After being pressed down, the combination switch will revert to the ON position again. The engine is switched off, but can be turned on again without moving the combination switch.

IMPORTANT: To cut off the ignition current, push the combination switch all the way down past the resistance point to the safety position.

What are the different combination switch positions?

• Cold start (Choke)
• Warm start (ON)
• Engine off
• Combination switch in safety position (ignition current cut off, necessary for all maintenance, repair, and installation work)

How do you check the chain brake?

The chain brake must be checked before every use of the saw! Start the engine as described above (have a secure footing, place the chain saw on the ground so that the chain and guide bar are not near anything).

Hold the front handle firmly, with your other hand on the rear grip. Let the engine run at medium speed and push the handguard in the direction of the arrow using the back of your hand, until the chain brake engages. The chain should now stop immediately. Bring the engine back to idle and release the chain brake.

What should you do if the chain does not stop immediately when you test the chain break?

If the chain does not stop immediately in this test, turn off the engine immediately. Do NOT use the chain saw in this condition! Contact a MAKITA service center.

Can you adjust the carburetor yourself?

CAUTION: Carburetor adjustment may only be done by a specialist MAKITA service center. Only adjusting screw (T) can be manipulated by the user. If the saw chain moves in idle (i.e. without the throttle being pressed), it is imperative to correct the idle speed.

When should you adjust the idle speed?

Do not adjust the idle speed until after complete assembly and testing of the saw! Idle speed adjustment must only be undertaken when the engine is warm, with a clean air filter and properly installed guide bar and chain.

Use a screwdriver (4 mm blade) for idle adjustments.

How do you adjust the idle speed?

• Turn adjusting screw (T) counter-clockwise (unscrew): Idle speed decreases.
• Turn adjusting screw (T) clockwise (screw in): Idle speed increases.

What should you do if the saw chain still moves during idle even after you have adjusted the idle speed?

Important: If the saw chain still moves during idle even after you have adjusted the idle speed, do NOT use the saw. Take it to a MAKITA service center!

What is the correct sharpening angle?

The sharpening angle must be identical for all cutters.

• 30° for chain type 492, 290

The teeth will have the proper angle automatically if the proper round file is used.

• 80° for chain type 492
• 75° for chain type 290

Different angles result in a roughly, irregularly running chain, increase wear and tear and cause chain breakage.

How do you sharpen the saw chain?

CAUTION: Before doing any work on the guide bar or chain, always switch off the engine and pull the plug cap off the spark plug (see “Replacing the spark plug”). Always wear protective gloves!

When does the chain need sharpening?

The chain needs sharpening when:

• The sawdust produced when sawing damp wood looks like wood flour.
• The chain penetrates the wood only under great pressure.
• The cutting edge is visibly damaged.
• The saw is pulled to the left or right when sawing. This is caused by uneven sharpening of the chain.

How often should you sharpen the chain?

Important: Sharpen frequently, but without removing too much metal! Generally, 2 or 3 strokes of the file will be enough. Have the chain resharpened at a service center when you have already sharpened it yourself several times.

What should you use to sharpen the chain?

CAUTION: Use only chains and guide bars designed for this saw! All cutters must be of the same length (dimension a). Cutters with different lengths result in rough running of the chain and can cause cracks in the chain. The minimum cutter length: 3 mm. Do not resharpen the chain when the minimum cutter length has been reached; at this point, the chain must be replaced (see the Extract from the spare-parts list and “Replacing the saw chain”).

What determines the depth of the cut?

The depth of the cut is determined by the difference in height between the depth limiter (round nose) and the cutting edge. The best results are obtained with a depth-limiter depth of 0.64 mm (.025").

What are the risks of excessive depth?

CAUTION: Excessive depth increases the risk of kickback!

What types of files should be used and how should you work with them?

Use a special saw chain round file for sharpening. Standard round files are unsuitable.

• Type 492: Saw chain round file, dia. 4.0 mm
• Type 290: Saw chain round file, dia. 4.5 mm.

The file should cut only when pushed forwards (arrow). Lift the file when leading it backwards. First sharpen the shortest cutter. The length of this cutter is then the standard for all other cutters of the chain. New saw teeth must be filed to the exact same shape as the used teeth, including on their running surfaces. File depending on chain type (90° or 10° to the guide bar). A file holder makes file guidance easier. It is marked for the correct sharpening angle of:

• α = 25°
• α = 30°
• α = 35°

(keep the marks parallel with the chain when filing) and limits the cut depth to the correct 4/5 of the file diameter.

What should you do after sharpening the chain?

After having sharpened the chain, the height of the depth limiter must be checked by means of a chain gauge. See “Accessories” for the order number. Correct even the smallest excess height with a special flat file. Round off the front of the depth limiter.

How do you clean the inside of the sprocket guard?

CAUTION: Before doing any work on the guide bar or chain, always switch off the engine and pull the plug cap off the spark plug (see “Replacing the spark plug”). Always wear protective gloves!

CAUTION: Start the chain saw only after having assembled it completely and inspected. Remove the sprocket guard (see PUTTING INTO OPERATION for the correct model) and clean out the interior with a brush.

What should you do after removing the sprocket guard?

Remove the chain and guide bar.

NOTE: Make sure there are no residues or foreign matter remaining in the oil guide groove or on the chain tensioner. To install the guide bar, saw chain, and sprocket guard, see PUTTING INTO OPERATION for the correct model.

How important is the chain brake?

NOTE: The chain brake is a very important safety device and like any other component subject to normal wear and tear. Regular inspection and maintenance are important for your own safety and must be done by a MAKITA service center.

How do you clean the guide bar?

CAUTION: Protective gloves must be worn. Regularly inspect the bearing surfaces of the guide bar for damage, and clean them with a suitable tool. Keep the two oiling holes and the entire guide bar clean and free of foreign matter!

When should you check the sprocket?

Check the sprocket before mounting a new chain. Worn out sprockets may damage the new chain and must therefore be replaced.

How do you replace the sprocket?

• Remove the sprocket guard (See “PUTTING INTO OPERATION”).
• Remove the chain and guide bar.
• Remove circlip.
• CAUTION: The circlip will pop out of the groove. When removing it, hold your thumb against it to prevent it from popping off.
• Remove thrust washer.
• If the sprocket is worn out, the complete clutch drum will need to be replaced.
• Install a complete new clutch drum, cup washer and new circlip.
• For replacing the guide bar, chain, and sprocket see “PUTTING INTO OPERATION.”

What should you do when using a new chain?

NOTE:

• Don’t use a new chain on a worn chain sprocket. By the time 2 chains have worn, the sprocket has become worn out, so it should be replaced at least at every second chain replacement. To distribute the chain oil evenly, run a new chain at half-throttle for a few minutes before use.
• New chains stretch, so check the chain tension frequently (see “Checking the chain tension”).

How do you replace the saw chain?

CAUTION: Use only chains and guide bars designed for this saw!

How do you clean the air filter?

CAUTION: To prevent eye injury, always wear eye protection when cleaning the filter with compressed air! Do not use fuel to clean the air filter. Insert the universal wrench vertically through the slotted plug. Loosen the screw counter-clockwise and remove the hood. Push up the combination switch (Choke position) to prevent dirt particles from falling into the carburetor. Pull the air filter cover tab slightly in the direction of the arrow, and remove the air filter cover. Remove the air filter.

IMPORTANT: Cover the intake opening with a clean cloth to prevent dirt particles from getting into the carburetor.

How do you clean a dirty air filter?

If the filter is very dirty, clean it in lukewarm water with dishwashing detergent. Let the air filter dry completely. If the filter is very dirty, clean it frequently (several times a day), because only a clean air filter provides full engine power.

CAUTION: Replace damaged air filters immediately. Pieces of cloth or large dirt particles can destroy the engine!

What should you do after cleaning the air filter?

• Insert the air filter.
• Put on the air filter cover.
• Note: The air filter cover tab will engage automatically if the air filter cover is properly positioned.
• Push down the combination switch and press the throttle all the way down one time in order to deactivate the throttle lock.
• Put on the hood. When doing so make sure that the lower pins on both sides of the hood engage properly (when correctly assembled, the pins should not be visible).
• Tighten screw clockwise.

How do you replace the spark plug?

CAUTION:

• Do not touch the spark plug or plug cap if the engine is running (high voltage).
• Switch off the engine before starting any maintenance work. A hot engine can cause burns. Wear protective gloves!

The spark plug must be replaced in case of damage to the insulator, electrode erosion (burn) or if the electrodes are very dirty or oily.

How do you remove the spark plug?

• Remove the filter cover (see “Cleaning the air filter”).
• Pull the plug cap off the spark plug.
• Use only the combination wrench supplied with the saw to remove the spark plug.

What is the proper electrode gap?

CAUTION: Danger of injury! Secure the cable grip when pulled out! It will whip back if the cable pulley is released by accident.

How do you replace the return spring pack?

1. Disassemble the fan housing and cable drum.
2. Lightly tap the fan housing on a wooden surface with the entire surface of the hollow side, and hold it down. Now lift the fan housing carefully and in small steps. This will allow the return spring pack, which should now have fallen out, to relax in a controlled manner if the return spring has popped out of the plastic pack.
3. Carefully insert a new return spring cassette and press down until it engages. Place the cable drum on it and turn it slightly until the return spring engages. Install the spring and driver and screw on tight with screw.
4. Tension the spring.

CAREFUL! Injury hazard! The return spring can pop out! Always wear eye protection and protective gloves!
