Intended use

The tool is intended for planing wood.

Power supply

The tool should be connected only to a power supply of the same voltage as indicated on the nameplate, and can only be operated on single-phase AC supply. They are double-insulated and can, therefore, also be used from sockets without earth wire.

Noise

The typical A-weighted noise level determined accord- ing to EN60745:
Sound pressure level (LpA) : 84 dB(A) Sound power level (LWA) : 95 dB (A) Uncertainty (K) : 3 dB(A)

Vibration

The vibration total value (tri-axial vector sum) deter- mined according to EN60745:
Work mode: planing softwood Vibration emission (ah) : 3.0 m/s2 Uncertainty (K) : 1.5 m/s2

EC Declaration of Conformity

For European countries only

For the correct planer blade setting

Your planing surface will end up rough and uneven, unless the planer blade is set properly and securely. The planer blade must be mounted so that the cutting edge is absolutely level, that is, parallel to the surface of the rear base. Refer to some examples below for proper and improper settings.

(A) Első alap (mozgó láb)
(B) Hátsó alap (álló láb)

Connecting a vacuum cleaner

For European countries only

**10

When you wish to perform clean planing operation, connect a Makita vacuum cleaner to your tool. Then connect a hose of the vacuum cleaner to the nozzle as shown in the figures.
**

OPERATION

Hold the tool firmly with one hand on the knob and the other hand on the switch handle when performing the tool.

Planing operation

11: 1. Start 2. End

Apply the tool front base flat upon the workpiece surface without the planer blades contacting the work- piece. Switch on and wait until the blades attain full speed. Then move the tool gently forward at a uniform speed. Apply pressure on the front of tool at the start of planing, and on the rear at the end of planing.
The speed and depth of cut determine the finish. To obtain a good surface finish, plane deeply until you get near the desired depth, and then plane thinly and slowly for the final pass.

Shiplapping (Rabbeting)

**12

**

To make a stepped cut as shown in the figure, use the\ edge fence (guide rule).
Draw a cutting line on the workpiece. Insert the edge fence into the hole in the front of the tool. Align the blade edge with the cutting line.

13: 1. Blade edge 2. Cutting line

Adjust the edge fence until it comes in contact with the side of the workpiece, then secure it by tightening the screw.

14: 1. Screw 2. Edge fence

When planing, move the tool with the edge fence flush with the side of the workpiece. Otherwise uneven plan- ing may result.

**15

**

Maximum shiplapping (rabbeting) depth is 9 mm (11/32″).
You may wish to add to the length of the fence by attaching an extra piece of wood. Convenient holes are provided in the fence for this purpose, and also for attaching an extension guide (optional accessory).

Chamfering

**18

**

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

MAINTENANCE

Sharpening the planer blades

For conventional planer blades only

Always keep your planer blades sharp for the best per- formance possible. Use the sharpening holder (optional accessory) to remove nicks and produce a fine edge.

19: 1. Sharpening holder

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

20: 1. Wing nut 2. Planer blade (A) 3. Planer

blade (B) 4. Side (D) 5. Side (C)
Immerse the dressing stone in water for 2 or 3 minutes before sharpening. Hold the holder so that the both blades contact the dressing stone for simultaneous sharpening at the same angle.

Replacing carbon brushes

22: 1. Limit mark

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. Use a screwdriver to remove the chip cover or nozzle.

23: 1. Chip cover or Nozzle 2. Screwdriver

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.

24: 1. Brush holder cap 2. Screwdriver

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