1. This unit is designed to provide sufficient polishing (sanding) power with the disc pressed
lightly against the sanding/polishing surface: it is equipped with an electronic control
circuit to ensure that the motor will not slow down even when loaded. There is threfore
no need to press the sanding disc hard against the surface; doing so can overload the
motor, subsequently causing the overload cut device to step into operation by cutting the
motor's power supply. If this should happen, cut the power switch and turn it back on to
reset the unit: it will resume rotation at the correct motor speed.
2. Rather than applying the entire disc surface to
the metal surface to be ground, use the sander
by inclining it approximately 15°~25° to grind
with the disc peripheral portion. (Fig. 3).
3. Switching on the sander polisher
When the trigger is pulled, the switch is turned
ON, when the trigger is released, the switch is
turned OFF.
4. Precaution after use
Do not lay the sander polisher down immediately
after use in a place where there are many
shavings and much dirt and dust until it has
completely stopped revolving.
For use as a Polisher
1. Curved surface as well as plain one is treated for finishing. It is recommended to hold the
polisher without pushing on the material, and make the best of its own weight as the
excess pressure on the polishing surface will not only bring unsatisfactory result but also
put unnecessory load on the motor.
2. Polishing compound or wax are used corresponding to the state of finishing and the
maximum polishing effect will be attained when the following method is taken.
Polishing with a sander using fine sanding disc.
Polishing with wool bonnet using compound substance final waxing.
First put the compound and wax in small quantity on the surface to be polished, then, give
a polish with the wool bonnet.
CAUTION: Carefully guard against permitting the cord to touch the wool bonnet or
sanding disc during operation. If the cord touches them, there is danger that
it may become entangled.
