OPERATING INSTRUCTIONS
Installing or removing abrasive paper
Important:
Always be sure that the tool is switched off and
unplugged before installing or removing the abrasive
paper.
For conventional type of abrasive paper with pre-
punched holes (standard equipment):
Press the clamper. Insert the paper end into the clamper,
aligning the holes in the paper with those in the pad.
Then release the clamper to secure the paper. Repeat
the same process for the other end of the base, maintain-
ing the proper paper tension. (Fig. 1)
For conventional type of abrasive paper without pre-
punched holes (available on the market):
Press the clamper. Insert the paper end into the clamper,
aligning the paper edges even and parallel with the sides
of the base. Then release the clamper to secure the
paper. Repeat the same process for the other end of the
base, maintaining the proper paper tension. 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. (Fig. 2)
For hook-and-loop type of abrasive paper with pre-
punched holes (optional accessory):
Remove the pad for the conventional type of abrasive
paper from the tool with a screwdriver. (Fig. 3)
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. Remove all dirt or for-
eign matter from the pad. Attach the paper to the pad,
aligning the holes in the paper with those in the pad.
(Fig. 4)
CAUTION:
Always use hook-and-loop type of abrasive papers.
Never use pressure-sensitive abrasive paper.
Installing dust bag (Fig. 5)
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 com-
ing off during operation. For the best results, empty the
dust bag when it becomes about half full, tapping it lightly
to remove as much dust as possible.
Switch action (Fig. 6)
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 trigger. Release the trig-
ger 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.
Operation (Fig. 7)
Turn the tool on and wait until it attains full speed. Then
gently place the tool on the workpiece surface. Keep the
base flush with the workpiece and apply a light pressure
on the tool.
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.

MAINTENANCE

CAUTION:
Always be sure that the tool is switched off and
unplugged before carrying out any work on the tool.
To maintain product safety and reliability, repairs, mainte-
nance or adjustment should be carried out by a Makita
Authorized Service Center.
