AUXILIARY HANDLE
 The auxiliary side handle houses the wheel lock nut
wrench. To remove the wheel lock nut wrench from
the auxiliary handle, pull it out by the two lugs on the
wrench. When finished with the wrench, slide it back in
to the auxiliary handle with the lugs facing out.
 The auxiliary handle can be attached to either or the
upper part of the gear box.
SWITCH
 To turn the tool on, press the lock button about halfway
in and then pull the switch trigger.
 For continuous operation, press the lock button in
completely.

To turn the tool off, pull and release the switch trigger.
TOOL-LESS WHEEL GUARD
Release the wheel guard lock lever, then turn the tool-
less wheel guard to the desired position. The maximum.
turning angle is 90° on either side; otherwise, the guard
cannot be locked.
VARIABLE SPEED CONTROL
The tool features variable speed control which enables
you to select the most appropriate speed for the job.
Application Speed setting
Polishing 1 - 3
Sanding 3 - 5
Grinding 6
The speed of rotation can be changed by adjusting the
speed control switch to the most suitable speed for the
job. The general rules for operating speed are as follows:
Grinding: high speed
Sanding: high speed
Polishing: low speed
WARNING
Never become complacent while using your grinder
sander, as carelessness can result in serious personal
injury.
MOUNTING THE GRINDING WHEEL
See Figure 2.
Inspect grinding wheel before installing.
Do not use
broken or defective parts.
 Unplug the tool.
WARNING
Failure to unplug your grinder sander could result in
accidental starting causing possible serious personal
injury.
 Attach the disc flange and the wheel on the spindle
before fitting the clamp nut.
 Ensure that the wheel is correctly seated over the boss
on the disc flange and clamp nut.
 Depress the spindle lock button located at the right
side of the gear case.
 Using the wrench provided, tighten the clamp nut in a
clockwise direction.
MOUNTING THE SANDING PAD

GRINDING
See Figure 6.
The key to ef fi cient operation is balanced control of the
pressure and surface contact between the grinding wheel
and workpiece. Flat surfaces are ground at an acute
angle, usually 15 to 20 degrees with the workpiece. Allow
the wheel to reach full speed before starting to grind.
Too great an angle causes concentration of pressure
on a small area which may gouge or ruin the workpiece.
Maximum rpm is required for grinding.
