ASSEMBLY
CAUTION:
• Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
Installing or removing abrasive paper
For conventional type of abrasive paper with pre-
punched holes (standard equipment): (Fig. 2)
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.
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.
To remove the paper, release the clamper as stated
above.
For conventional type of abrasive paper without pre-
punched holes (available on the market): (Fig. 3)
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.
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.
Place the punch plate (optional accessory) over the paper
so that the guide of the punch plate is flush with the sides
of the base. Then press the punch plate to make holes in
the paper.
To remove the paper, release the clamper as stated
above.
For hook-and-loop type of abrasive paper with pre-
punched holes (optional accessory):
CAUTION:
• Always use hook-and-loop type of abrasive papers.
Never use pressure-sensitive abrasive paper. (Fig. 4)
Remove the pad for the conventional type of abrasive
paper from the tool with a screwdriver. Install the pad for
the hook-and-loop type of abrasive paper (optional
accessory) on the tool. Tighten the screws firmly to secure
the pad. (Fig. 5)
Remove all dirt or foreign matter from the pad. Attach the
paper to the pad, aligning the holes in the paper with
those in the pad. (Fig. 6)
CAUTION:
• When removing the pad, O ring may come out of the
tool. When this occurs, return the O ring to the original
position and then install the pad.
Dust bag (optional accessory) (Fig. 7)
Attach the dust bag onto the dust spout. The dust spout is
tapered. When attaching the dust bag, push it onto the
dust spout firmly as far as it will go to prevent it from
coming off during operation.
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 filter (optional accessory)
(Fig. 8)
Make sure that the logo on the cardboard lip and the logo
on the dust box are on the same side, then install the filter
by fitting the cardboard lip in the groove of each holding
tab. (Fig. 9)
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 filter.
(Fig. 10)
Remove the dust nozzle by pushing the two latches.
(Fig. 11)
Remove the filter 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
box.
OPERATION
Sanding operation (Fig. 12)
CAUTION:
• 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
maintenance.
• 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
replacement parts.
