Note: Manufacturer reserves the right to change specifications without notice. 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.

4. Double insulated tools are 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.

5. 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.

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

7. 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.

8. 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.

9. 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.

10. 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.

11. 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.

12. 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.

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

14. Use safety equipment. Always wear eye protection. Dust mask, non-skid safety shoes, hard hat, or hearing protection must be used for appropriate conditions. Ordinary eye or sun glasses are NOT eye protection.

15. 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.

16. 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.

17. 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.

18. 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.

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

20. 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.

21. 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.

22. 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.

23. Tool service must be performed only by qualified repair personnel. Service or maintenance performed by unqualified personnel could result in a risk of injury.

24. When servicing a tool, use only identical replacement parts. Follow instructions in the Maintenance section of this manual. Use of unauthorized parts or failure to follow Maintenance instructions may create a risk of electric shock or injury.

Make sure your extension cord is in good condition. When using an extension cord, be sure to use one heavy enough to carry the current your product will draw. An undersized cord will cause a drop in line voltage resulting in loss of power and overheating. Table 1 shows the correct size to use depending on cord length and nameplate ampere rating. If in doubt, use the next heavier gage. The smaller the gage number, the heavier the cord.

DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to planer safety rules. If you use this tool unsafely or incorrectly, you can suffer serious personal injury.

1. Rags, cloth, cord, string and the like should never be left around the work area.

2. Avoid cutting nails. Inspect for and remove all nails from the workpiece before operation.

3. Use only sharp blades. Handle the blades very carefully.

4. Be sure the blade installation bolts are securely tightened before operation.

5. Hold the tool firmly with both hands.

6. Keep hands away from rotating parts.

7. Before using the tool on an actual workpiece, let it run for a while. Watch for vibration or wobbling that could indicate poor installation or a poorly balanced blade.

8. Make sure the blade is not contacting the workpiece before the switch is turned on.

9. Wait until the blade attains full speed before cutting.

10. Keep at least 200 mm (8″) away from the tool at all times.

11. Always switch off and wait for the blades to come to a complete stop before any adjusting.

12. Never stick your finger into the chip chute. Chute may jam when cutting damp wood. Clean out chips with a stick.

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

14. When leaving the planer, switch off and set it with the front base up on a wooden block, so that the blades do not contact anything.

15. Always change both blades or covers on the drum, otherwise the resulting imbalance will cause vibration and shorten tool life.

16. Wait for complete run-down before putting the tool aside.

17. Use only Makita blades specified in this manual.

18. Some material contains chemicals which may be toxic. Take caution to prevent dust inhalation and skin contact. Follow material supplier safety data.

Depth of cut may be adjusted by simply turning the knob on the front of the tool.

CAUTION: Always be sure that the tool is switched off and unplugged before adjusting or checking function on the tool.

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 switch trigger. Release the switch trigger to stop.

For continuous operation, pull the switch trigger and then push in the lock button.

To stop the tool from the locked position, pull the switch trigger fully, then release it.

CAUTION: Always be sure that the tool is switched off and unplugged before carrying out any work on the tool.

CAUTION: Tighten the blade installation bolts carefully when attaching the blades to the tool. A loose installation bolt can be dangerous. Always check to see they are tightened securely.

To remove the blades on the drum, unscrew the installation bolts (1) with the socket wrench. The drum cover (4) comes off together with the blades (3).

To install the blades, first clean out all chips or foreign matter adhering to the drum (2) or blades. Use blades of the same dimensions and weight, or drum oscillation/vibration will result, causing poor planing action and, eventually, tool breakdown.

Place the blade (6) on the gauge base (8) so that the blade edge (5) is perfectly flush with the inside edge of the gauge plate (7). Place the adjust plate (1) on the blade, then simply press in the heel of the adjust plate (3) flush with the back side of the gauge base (4) and tighten two screws (2) on the adjust plate. Now slip the heel of the adjust plate into the drum groove, then fit the drum cover on it. Tighten the installation bolts evenly and alternately with the socket wrench.

Your planing surface will end up rough and uneven, unless the blade is set properly and securely. The blade must be mounted so that the cutting edge is absolutely level, that is, parallel to the surface of the rear base (Stationary shoe (B)).

Below are some examples of proper and improper settings:

• Correct setting: The edges of the blades run perfectly parallel to the rear base surface. (Although the side view cannot show it).
• Nicks in surface: Cause: One or both blades fails to have edge parallel to rear base line.
• Gouging at start: Cause: One or both blade edges fails to protrude enough in relation to rear base line.
• Gouging at end: Cause: One or both blade edges protrudes too far in relation to rear base line.

(A) refers to the Front base (Movable shoe) and (B) refers to the Rear base (Stationary shoe).

First, rest the tool front base flat upon the workpiece surface without the blades making any contact. Switch on and wait until the blades attain full speed. Then move the tool gently forward. Apply pressure on the front of tool at the start of planing (1), and at the back at the end of planing (2). Planing will be easier if you incline the workpiece in stationary fashion, so that you can plane somewhat downhill.

The speed and depth of cut determine the kind of finish. The power planer keeps cutting at a speed that will not result in jamming by chips. For rough cutting, the depth of cut can be increased, while for a good finish you should reduce the depth of cut and advance the tool more slowly.

To make a cut as shown in the figure, align the “V” groove (1) in the front base (2) with the edge of the workpiece and plane it as shown.

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

Always keep your blades sharp for the best performance possible. Use the sharpening holder (1) to remove nicks and produce a fine edge.

First, loosen the two wing nuts (1) on the holder and insert the blades (A) (2) and (B) (3), so that they contact the sides (C) (4) and (D) (5). Then tighten the wing nuts.

Immerse the dressing stone in water for 2 or 3 minutes before sharpening. Hold the holder so that the blades both contact the dressing stone for simultaneous sharpening at the same angle.

To maintain product SAFETY and RELIABILITY, repairs, carbon brush inspection and replacement, any other maintenance or adjustment should be performed by Makita Authorized or Factory Service Centers, always using Makita replacement parts.

Always keep blades sharp using the sharpening holder assembly and dressing stone.

CAUTION: These accessories or attachments are recommended for use with your Makita tool specified in this manual. The use of any other accessories or attachments might present a risk of injury to persons. Only use accessory or attachment for its stated purpose.
