MAKITA HR3000C (01) PDF Document

* Note: Specifications may differ from country to country.

1. Keep your work area clean and well lit. Cluttered benches and dark areas invite accidents.

2. Do not operate power tools in explosive atmospheres, such as in the presence of flammable liquids, gases, or dust. Power tools create sparks which may ignite the dust or fumes.

3. Keep bystanders, children, and visitors away while operating a power tool. Distractions can cause you to lose control.

1. The MAKITA HR3000C is a Double Insulated tool equipped with a polarized plug (one blade is wider than the other). This plug will fit in a polarized outlet only one way. If the plug does not fit fully in the outlet, reverse the plug. If it still does not fit, contact a qualified electrician to install a polarized outlet. Do not change the plug in any way. Double insulation eliminates the need for the three wire grounded power cord and grounded power supply system.

2. Avoid body contact with grounded surfaces such as pipes, radiators, ranges and refrigerators. There is an increased risk of electric shock if your body is grounded.

3. Do not expose power tools to rain or wet conditions. Water entering a power tool will increase the risk of electric shock.

4. Do not abuse the cord. Never use the cord to carry the tools or pull the plug from an outlet. Keep cord away from heat, oil, sharp edges or moving parts. Replace damaged cords immediately. Damaged cords increase the risk of electric shock.

5. When operating a power tool outside, use an outdoor extension cord marked “W-A” or “W.” These cords are rated for outdoor use and reduce the risk of electric shock.

1. Stay alert, watch what you are doing and use common sense when operating a power tool. Do not use tool while tired or under the influence of drugs, alcohol, or medication. A moment of inattention while operating power tools may result in serious personal injury.

2. Dress properly. Do not wear loose clothing or jewelry. Contain long hair. Keep your hair, clothing, and gloves away from moving parts. Loose clothes, jewelry or long hair can be caught in moving parts.

3. Avoid accidental starting. Be sure switch is off before plugging in. Carrying tools with your finger on the switch or plugging in tools that have the switch on invites accidents.

4. Remove adjusting keys or wrenches before turning the tool on. A wrench or a key that is left attached to a rotating part of the tool may result in personal injury.

5. Do not overreach. Keep proper footing and balance at all times. Proper footing and balance enables better control of the tool in unexpected situations.

6. Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions.

1. Use clamps or other practical way to secure and support the workpiece to a stable platform. Holding the work by hand or against your body is unstable and may lead to loss of control.

2. Do not force tool. Use the correct tool for your application. The correct tool will do the job better and safer at the rate for which it is designed.

3. Do not use tool if switch does not turn it on or off. Any tool that cannot be controlled with the switch is dangerous and must be repaired.

4. Disconnect the plug from the power source before making any adjustments, changing accessories, or storing the tool. Such preventive safety measures reduce the risk of starting the tool accidentally.

5. Store idle tools out of reach of children and other untrained persons. Tools are dangerous in the hands of untrained users.

6. Maintain tools with care. Keep cutting tools sharp and clean. Properly maintained tools, with sharp cutting edges are less likely to bind and are easier to control.

7. Check for misalignment or binding of moving parts, breakage of parts, and any other condition that may affect the tools operation. If damaged, have the tool serviced before using. Many accidents are caused by poorly maintained tools.

8. Use only accessories that are recommended by the manufacturer for your model. Accessories that may be suitable for one tool, may become hazardous when used on another tool.

1. Hold tools by insulated gripping surfaces when performing an operation where the cutting tool may contact hidden wiring or its own cord. Contact with a “live” wire will make exposed metal parts of the tool “live” and shock the operator.

2. Wear ear protectors when using the tool for extended periods. Prolonged exposure to high intensity noise can cause hearing loss.

3. Wear a hard hat (safety helmet), safety glasses and/or face shield. It is also highly recommended that you wear a dust mask and thickly padded gloves.

4. Be sure the bit is secured in place before operation.

5. Under normal operation, the tool is designed to produce vibration. The screws can come loose easily, causing a breakdown or accident. Check tightness of screws carefully before operation.

6. In cold weather or when the tool has not been used for a long time, let the tool warm up for several minutes by operating it under no load. This will loosen up the lubrication. Without proper warm-up, hammering operation is difficult.

7. Always be sure you have a firm footing. Be sure no one is below when using the tool in high locations.

8. Hold the tool firmly with both hands.

9. Keep hands away from moving parts.

10. Do not leave the tool running. Operate the tool only when hand-held.

11. Do not point the tool at any one in the area when operating. The bit could fly out and injure someone seriously.

12. Do not touch the bit or parts close to the bit immediately after operation; they may be extremely hot and could burn your skin.

The symbols used for the tool are as follows:

V …………………… volts

A …………………… amperes

Hz …………………. hertz

~ …………………… alternating current

n₀ ………………….. no load speed

☐ …………………. Class II Construction (Double Insulation)

…/min ……………. revolutions or reciprocation per minute

Hammer Symbol ……. number of blow

When selecting an action mode, first set the change lever and the shift lever to the “Rotation with hammering” position. Then proceed as follows:

Rotation with hammering: For drilling in concrete, masonry, etc., depress the lock button and rotate the change lever so that the pointer points to the “T with hammer” symbol. Use a tungsten-carbide tipped bit.

Hammering only: For chipping, scaling or demolition operations, depress the lock button and rotate the change lever so that the pointer points to the “T” symbol. Use a bull point, cold chisel, scaling chisel, etc.

Rotation only: For drilling in wood, metal or plastic materials, rotate the shift lever so that the “drill” symbol is aligned with the pointer on the change lever. Use a twist drill bit or wood bit.

Yes, please observe the following cautions:

• Do not rotate the change lever and/or the shift lever when the tool is running under load. The tool will be damaged.

• To avoid rapid wear on the mode change mechanism, be sure that the change lever and/or the shift lever is always positively located in one of the three action mode positions.

• The action mode cannot be changed directly from “hammering only” to “rotation only” or from “rotation only” to “hammering only”. First set the change lever and the shift lever to the “rotation with hammering” mode position. Then set them to the position for “hammering only” or “rotation only”.

CAUTION: Always be sure that the tool is switched off and unplugged before changing the bit angle.

The bit can be secured at 12 different angles. To change the bit angle:

1. Depress the lock button and rotate the change lever so that the pointer points to the O symbol.

2. Turn the bit to the desired angle.

3. Depress the lock button and rotate the change lever so that the pointer points to the “T” symbol (Hammering only).

4. Make sure that the bit is securely held in place by turning it slightly.

CAUTION: Always use the side grip to ensure operating safety when drilling in concrete, masonry, etc. When the bit begins to break through concrete or if the bit strikes reinforcing rods embedded in concrete, the tool may react dangerously. Maintain good balance and safe footing while holding the tool firmly with both hands to prevent dangerous reaction.

The side grip swings around to either side, allowing easy handling of the tool in any position. To adjust it:

1. Loosen the side grip by turning it counterclockwise.

2. Swing it to the desired position.

3. Tighten it by turning clockwise.

CAUTION: Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the “OFF” position when released.

To start the tool, simply pull the trigger. Release the trigger to stop.

The revolutions and blows per minute can be adjusted just by turning the adjusting dial. The dial is marked 1 (lowest speed) to 6 (full speed). Refer to the table below for the relationship between the number settings on the adjusting dial and the revolutions/blows per minute.

The depth gauge is convenient for drilling holes of uniform depth.

1. Loosen the clamp screw.

2. Adjust the depth gauge to the desired depth.

3. After adjusting, tighten the clamp screw firmly.

NOTE: The depth gauge cannot be used at the position where the depth gauge strikes against the gear housing/motor housing.

Green Power-ON Indicator Lamp: This lamp lights up when the tool is switched ON. If the indicator lamp is lit but the tool does not start, the carbon brushes may be worn out, or the electric circuit or the motor may be defective. If the indicator lamp does not light up and the tool does not start, the ON/OFF switch or the mains cord may be defective.

Red Service Indicator Lamp: This lamp lights up when the carbon brushes are nearly worn out to indicate that the tool needs servicing. After approx. 8 hours of use, the motor will automatically be shut off.

CAUTION: Always be sure that the tool is switched off and unplugged before installing or removing the bit.

To Install a Bit:

1. Clean the bit shank and apply the bit grease provided to it before installing the bit.

2. Insert the bit into the tool. Turn the bit and push it in until it engages.

3. If the bit cannot be pushed in, remove the bit. Pull the chuck cover down a couple of times. Then insert the bit again. Turn the bit and push it in until it engages.

4. After installing, always make sure that the bit is securely held in place by trying to pull it out.

To Remove a Bit:

1. Pull the chuck cover down all the way and pull the bit out.

CAUTION: When the bit begins to break through concrete or if the bit strikes reinforcing rods embedded in concrete, the tool may react dangerously. Maintain good balance and safe footing while holding the tool firmly with both hands to prevent dangerous reaction.

1. Set the change lever and the shift lever to the “T with hammer” symbol (Rotation with hammering).

2. Position the bit at the location for the hole, then pull the trigger.

3. Do not force the tool. Light pressure gives best results. Keep the tool in position and prevent it from slipping away from the hole.

4. Do not apply more pressure when the hole becomes clogged with chips or particles. Instead, run the tool at an idle, then remove from the hole. By repeating this several times, the hole will be cleaned out.

The torque limiter will actuate when a certain torque level is reached. The motor will disengage from the output shaft. When this happens, the bit will stop turning.

CAUTION: As soon as the torque limiter actuates, switch off the tool immediately. This will help prevent premature wear of the tool.

1. Set the change lever and the shift lever to the “T” symbol (Hammering only).

2. Hold the tool firmly with both hands.

3. Turn the tool on and apply slight pressure on the tool so that the tool will not bounce around, uncontrolled.

4. Pressing very hard on the tool will not increase the efficiency.

Set the change lever and the shift lever to the “drill” symbol.

Drilling in wood: Best results are obtained with wood drills equipped with a guide screw. The guide screw makes drilling easier by pulling the bit into the workpiece.

Drilling in metal: To prevent the bit from slipping when starting a hole, make an indentation with a center-punch and hammer at the point to be drilled. Place the point of the bit in the indentation and start drilling. Use a cutting lubricant when drilling metals. The exceptions are iron and brass which should be drilled dry.

CAUTION: Pressing excessively on the tool will not speed up the drilling. In fact, this excessive pressure will only serve to damage the tip of your bit, decrease the tool performance and shorten the service life of the tool.

Use the optional drill chuck assembly (consisting of drill chuck and chuck adapter assembly) for drilling in wood or metal.

1. When installing it, refer to the “installing or removing drill bit” instructions.

2. Set the action mode changing knob to “rotation only”.

3. You can drill up to 13 mm (1/2″) diameter in metal and up to 30 mm (1-3/16″) diameter in wood.

CAUTION: Never use “rotation with hammering” when the drill chuck assembly is installed on the tool. The drill chuck assembly may be damaged. Also, the drill chuck will come off when reversing the tool.

CAUTION: Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.

When the resin insulating tip inside the carbon brush is exposed to contact the commutator, it will automatically shut off the motor. When this occurs, both carbon brushes should be replaced at the same time. Use only identical carbon brushes.

1. Use a screwdriver to remove the brush holder cover.

2. Use a screwdriver to remove the brush holder caps.

3. Take out the worn carbon brushes, insert the new ones and secure the brush holder caps.

This tool requires no hourly or daily lubrication because it has a grease-packed lubrication system. Lubricate the tool every time the carbon brushes are replaced.

1. Run the tool for several minutes to warm it up. Switch off and unplug the tool.

2. Loosen the six screws and remove the handle. Note that the top screws are different from other screws.

3. Disconnect the connector by pulling it.

4. Remove the crank cap using a hex wrench.

5. Rest the tool on the table with the bit end pointing upwards. This will allow the old grease to collect inside the crank housing.

6. Wipe out the old grease inside and replace with a fresh grease (30 g). Use only Makita genuine hammer grease (optional accessory). Filling with more than the specified amount of grease (approx. 30 g) can cause faulty hammering action or tool failure. Fill only with the specified amount of grease.

7. Reinstall the crank cap and tighten with the hex wrench.

8. Connect the connector and reinstall the handle.

CAUTION:

• Be careful not to damage the terminal or lead wires especially when wiping out the old grease or installing the handle.

• Do not tighten the crank cap excessively. It is made of resin and is subject to breakage.
