6. Some material contains chemicals which may be

toxic. Take caution to prevent dust inhalation and

skin contact. Follow material supplier safety data.

7. Use of this tool to sand some products, paints and

wood could expose user to dust containing

hazardous substances. Use appropriate

respiratory protection.

FUNCTIONAL DESCRIPTION CAUTION:

• Always be sure that the tool is switched off and

unplugged before adjusting or checking function on the

Switch action (Fig. 1)

• Before plugging in the tool, always check to see that

the tool is switched off.

To start the tool, press the “ I ” side of the switch. To stop

the tool, press the “O”side of the switch.

9. Front fixing cardboard

10. Front side of paper dust bag

• Always be sure that the tool is switched off and

unplugged before carrying out any work on the tool.

Installing or removing abrasive paper

Open the paper clamp by raising on the lever to release

from the locking port and then Insert the paper end into

the clamping part, aligning the paper edges even and

parallel with the sides of the base. (Bending the paper

beforehand makes attachment easier). Once the paper is

in place, return the lever to its original position. (Fig. 3)

Repeat the same process for the other end of the base,

maintaining the proper paper tension.

After inserting the paper, make sure the clamping part

hold it securely. Otherwise the paper will be loose and

subject to slippage, resulting in uneven sanding operation.

When using the dust bag, make holes in the abrasive

paper using the punch plate as follows:

1. Set the tool upside down.

2. Place the punch plate over the abrasive paper so that

the bent sides of the punch plate are flush with the

3. Press the punch plate to make holes in the abrasive

• Be sure to remove the punch plate before operating the

Use Makita hook-and-loop sandpaper with this sander.

1. Set the tool upside down so that the pad is on top.

2. Position the sandpaper to fit the shape of the base. Be

sure to align the holes on the sandpaper with the holes

on the pad (the dust will be sucked into these holes; it

is therefore important to leave them open).

3. Press the paper firmly over the pad.

To remove the sandpaper:

1. Set the tool upside down so that the sandpaper is on

2. Grasping one corner of the sandpaper, peel it from the

• If the sandpaper is in good condition, save it for further

Dust bag (accessory) (Fig. 6)

The use of the dust bag makes sanding operations clean

and dust collection easy. To attach the dust bag, fit the

bag’s entry port onto the dust spout on the tool. Make sure

that the hole in the bag’s entry port is just over the pimple-

like protrusion on the dust spout. For the best results,

empty the dust bag when it becomes approximately half

full, tapping it lightly to remove as much dust as possible.

Installing paper dust bag (accessory)

Place the paper dust bag on the paper dust bag holder

with its front side upward. Insert the front fixing cardboard

of the paper dust bag into the groove of the paper dust

bag holder. (Fig. 8)

Then press the upper part of the front fixing cardboard in

arrow direction to hook it onto the claws. (Fig. 9 & 10)

Insert the notch of the paper dust bag into the guide of the

paper dust bag holder. Then install the paper dust bag

holder set on the tool.

Installing paper filter bag (Fig. 11)

Make sure that the logo on the cardboard lip and the logo

on the dust box are on the same side, then install the

paper filter bag by fitting the cardboard lip in the groove of

each holding tab. (Fig. 12)

Make sure that the logo on the cardboard lip and the logo

on the dust nozzle are on the same side, then install the

dust nozzle on the dust box.

Removing dust box and paper filter bag. (Fig. 13)

Remove the dust nozzle by pushing the two latches.

Remove the paper filter bag first by pinching the logo side

of its cardboard lip, then by pulling the cardboard lip

downwards to move it out of the holding tab of the dust

OPERATION Sanding operation (Fig. 15)

• Never run the tool without the abrasive paper. You may

seriously damage the pad.

• Never force the tool. Excessive pressure may decrease

the sanding efficiency, damage the abrasive paper and/

or shorten tool life.

Hold the tool firmly. Turn the tool on and wait until it attains

full speed. Then gently place the tool on the workpiece

surface. A finishing sander is generally used to remove

only a small amount of material at a time. Since the quality

of the surface is more important than the amount of stock

removed, do not bear down on the tool. Keep the base

flush with the workpiece at all times.

MAINTENANCE CAUTION:

• Always be sure that the tool is switched off and

unplugged before attempting to perform inspection or

• Never use gasoline, benzine, thinner, alcohol or the

like. Discoloration, deformation or cracks may result.

To maintain product SAFETY and RELIABILITY, repairs,

carbon brush inspection and replacement, any other

maintenance or adjustment should be performed by

Makita Authorized Service Centers, always using Makita
