For use as a Sander
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. 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.
