SAFETY WARNINGS

General Power Tool Safety Warnings

⚠ WARNING Read all safety warnings, instructions, illustrations and specifications provided with this power tool. Failure to follow all instructions listed below may result in electric shock, fire and/or serious injury.

Save all warnings and instructions for future reference.

The term “power tool” in the warnings refers to your mains-operated (corded) power tool or battery-operated (cordless) power tool.

PLANER SAFETY WARNINGS

1. Wait for the cutter to stop before setting the tool down. An exposed rotating cutter may engage the surface leading to possible loss of control and serious injury.
2. Hold the power tool by insulated gripping surfaces, because the cutter may contact its own cord. Cutting a "live" wire may make exposed metal parts of the power tool "live" and could give the operator an electric shock.
3. Use clamps or another practical way to secure and support the workpiece to a stable platform. Holding the workpiece by your hand or against the body leaves it unstable and may lead to loss of control.
4. Rags, cloth, cord, string and the like should never be left around the work area.
5. Avoid cutting nails. Inspect for and remove all nails from the workpiece before operation.
6. Use only sharp blades. Handle the blades very carefully.
7. Be sure the blade installation bolts are securely tightened before operation.
8. Hold the tool firmly with both hands.
9. Keep hands away from rotating parts.
10. 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.
11. Make sure the blade is not contacting the workpiece before the switch is turned on.
12. Wait until the blade attains full speed before cutting.
13. Always switch off and wait for the blades to come to a complete stop before any adjusting.
14. Never stick your finger into the chip chute. Chute may jam when cutting damp wood. Clean out chips with a stick.
15. Do not leave the tool running. Operate the tool only when hand-held.
16. Always change both blades or covers on the drum, otherwise the resulting imbalance will cause vibration and shorten tool life.
17. Use only Makita blades specified in this manual.
18. Always use the correct dust mask/respirator for the material and application you are working with.

SAVE THESE INSTRUCTIONS.

WARNING:

DO NOT let comfort or familiarity with product (gained from repeated use) replace strict adherence to safety rules for the subject product.

MISUSE or failure to follow the safety rules stated in this instruction manual may cause serious personal injury.

FUNCTIONAL DESCRIPTION

CAUTION:

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

Adjusting depth of cut (Fig. 1)

The depth of cut can be adjusted within a range of 0 - 3.5 mm. Turn the knob on the front of the tool until the pointer is aligned with the desired cutting depth on the scale. Set the depth of a cut observing the maximum depth which is limited by width according to the following table.

Correlation of width of cut and maximum depth of cut

Width of cut Maximum	m depth of cut
0 – 150 mm 3.5 mm
150 – 240 mm 2 mm
240 – 312 mm 1.5 mm

Switch action (Fig. 2)

CAUTION:

- Before plugging in the tool, always check to see that the switch trigger actuates properly and returns to the "OFF" position when released.

For tool with lock button

To start the tool, simply pull the trigger. Release the trigger to stop. For continuous operation, pull the trigger and then push in the lock button. To stop the tool from the locked position, pull the trigger fully, then release it.

For tool with lock-off button

To prevent the trigger from being accidentally pulled, a lock-off button is provided. To start the tool, press the lock-off button and pull the trigger. Release the trigger to stop.

Overload protector (Option)

This tool is equipped with an overload protector which automatically cuts out to break the circuit whenever heavy work is prolonged. When it cuts out, inspect the blade for damage or something wrong. After making sure that there is nothing wrong with the tool, push the restart button to resume operation.

Edge fence (Guide rule) (Fig. 3)

Edge fence is useful for minimizing a short run of cut by cutting in a uniform width. The edge fence (guide rule) is provided on the side of the tool. Press two pins for the edge fence (guide rule) so that the edge fence appears. Move the tool forward while keeping the flat surface of the edge fence in contact with the side of the workpiece. To return the edge fence to an original position, push it upwards from its underside.

Foot (Fig. 4)

After a cutting operation, raise the back side of the tool and a foot comes under the level of the rear base. This prevents the tool blades to be damaged.

Guideline of cutting blade passage (Fig. 5)

Both ends of the front base are a guideline to show the ends of cutting blades passage.

ASSEMBLY

CAUTION:

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

Removing or installing planer blades (Fig. 6)

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.
• Handle the blades very carefully. Use gloves or rags to protect your fingers or hands when removing or installing the blades.
• Use only the Makita wrench provided to remove or install the blades. Failure to do so may result in overtightening or insufficient tightening of the installation bolts. This could cause an injury.

To remove planer blades on the drum, loosen the eight installation bolts by only one full turn with the hex wrench.

Then push and slide a planer blade sideways from the belt side using the helm of the hex wrench.

To remove another planer blade, follow the same procedure as above. (Fig. 7 & 8)

To install the blades, first clean out all chips or foreign matter adhering to the drum or blades.

Insert the blade between the drum and the set plate from the nozzle extraction side so that the blade will be centered from both ends of the drum or set plate.

First tighten the eight installation bolts lightly and evenly shifting from the center bolts to the outward bolts with the hex wrench.

And then, tighten all of the installation bolts securely. Install another blade in the same manner as above.

(Fig. 9)

For the correct planer blade setting

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.

Below are some examples of proper and improper settings.

Blade height adjustment (Fig. 8)

Blade height adjustment is usually not necessary. However, if you notice that the blade edge is below the level of the rear base or protrudes too far from the rear base, proceed as follows.

Loosen the eight installation bolts and the set plate screws. Turn the adjusting screws clockwise to retract the blade or counterclockwise to protrude it. After adjusting the blade height, tighten the set plate screws and the eight installation bolts securely.

Hex wrench storage (Fig. 10)

When not in use, store the hex wrench as shown in the figure to keep it from being lost.

Dust

WARNING:

• Depending on the material being worked on and the accessory used, the dust created by use of the tool can be harmful. The user is recommended to use an appropriate dust extractor to reduce exposure.
  See the "OPTIONAL ACCESSORIES" section in this instruction manual for all optional dust extractor attachments available.

Additional Warnings:

• To prevent dust inhalation, it is recommended to also wear an FFP2 dust mask or P2 respirator.
- Read the "MAINTENANCE" section of the instruction manual of the connected dust extractor to keep the dust collection effective.
- Follow all applicable regulatory requirements for dust control in the country where the work is being conducted.

- Do not use a dust extractor for metalworking with power tools. Metal particles produced during metalworking can ignite accumulated dust and damage the dust filter inside dust extractors, posing a serious fire hazard.

- For European countries only The user is recommended to use an M or H dust class extractor (as defined in EN 60335-2-69).

For help and support regarding dust extractors, please contact your local Makita Service Center.

Connecting with a dust extractor

Nozzle assembly and joint (Accessory) (Fig. 11 & 12)

Nozzle assembly and joint are used when connecting the tool to vacuum cleaner.

When you wish to perform cleaner operation, connect a vacuum cleaner to your tool.

To connect vacuum cleaner, remove the chip guide from the tool. Place nozzle assembly and joint in its place and then tighten screws to secure them.

Connect a hose of vacuum cleaner to the joint.

Use the front cuff 38 to connect the hose.

The inner diameter of the joint for the hose connection is 45 mm.

Nozzle cleaning

Clean the nozzle regularly.

Use a compressed air to clean the clogged nozzle.

OPERATION

WARNING:

- To reduce the risk of injury to persons, do not operate without nozzle assembly and joint or chip guide in place.

Planing operation (Fig. 13)

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, and at the back at the end of planing. 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.

Front roller (Fig. 14)

When performing repeated cuts, the use of the front roller enables quick and effortless return of the tool toward an operator by raising the back end of the tool so that the tool blades do not contact a workpiece and then sliding tool on the front roller.

MAINTENANCE

CAUTION:

• Always be sure that the tool is switched off and unplugged before attempting to perform inspection or maintenance.
• Never use gasoline, benzine, thinner, alcohol or the like. Discoloration, deformation or cracks may result.

Replacing carbon brushes

Remove and check the carbon brushes regularly. Replace when they wear down to the limit mark. Keep the carbon brushes clean and free to slip in the holders. Both carbon brushes should be replaced at the same time. Use only identical carbon brushes. (Fig. 15) Use a screwdriver to remove the brush holder caps. Take out the worn carbon brushes, insert the new ones and secure the brush holder caps. (Fig. 16)

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