The tool speed can be infinitely adjusted between 4,000
and 11,000 orbits per minute by turning the speed adjust-
ing dial, which is marked 1 to 5. Higher speed is obtained
when the dial is turned in the direction of number 5, lower
speed is obtained when it is turned in the direction of
number 1. Adjust the desired tool speed for the kind of
work.
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. 3)
Press down the clamp lever (1 in the figure) and with the
clamp lever pressed down slide it toward the tool (2 in the
figure) and the clamper will be released.
Insert the paper end between a clamper and the pad
aligning the holes in the paper with those in pad. Then
return the clamp lever to the original position to secure it.
Release the other clamp lever by repeating the same
procedure.
While pulling abrasive paper to maintain the proper ten-
sion, insert and secure the other end of abrasive paper
between another clamper and the pad and return the
clamp lever to the original position.
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. 4)
Press down the clamp lever 1 and with the clamp lever
pressed down slide it toward the tool 2 and the clamper
will be released.
Insert the paper end between a clamper and the pad
aligning the paper edges even and parallel with the sides
of the base. Then return the clamp lever to the original
position to secure it.
Release the other clamp lever by repeating the same
procedure.
While pulling abrasive paper to maintain the proper ten-
sion, insert and secure the other end of abrasive paper
between another clamper and the pad and return the
paper clamp lever to the original position.
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): (Fig. 5, 6 & 7)
CAUTION:
• Always use hook-and-loop type of abrasive papers.
Never use pressure-sensitive abrasive paper.

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.
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.
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. 8)
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-

For the best results, empty the dust bag when it becomes
approximately half full, tapping it lightly to remove as
much dust as possible.

attains full speed. Then gently place the tool on the work-
piece surface. Keep the pad flush with the workpiece and
apply slight pressure on the tool.
