POLISHER OPERATION
1. Hold the polisher firmly by its housing and side handle (Fig. 1).
The polisher produces a counterforce which must be controlled by firmly holding onto
the polisher.
2. Switch operation
This enables the polisher always to be controlled with the hand gripping the machine for
maximum safety during polishing operations.
<Intermittent use>
Switch ON: Press the switch trigger.
Switch OFF: Release the switch trigger.
<Continuous use>
Switch ON: Press the switch trigger. The switch trigger is locked by pushing on
the locking button.
Switch OFF: Press and release the switch trigger.
3. Use light polishing pressure.
There is no need to press hard when polishing. Usually the polisher’s own weight is
sufficient to allow the required light contact with the surface to be ground.
CAUTION: Do not press the polisher forcibly against the surface to be ground. Heavy
pressure can damage the surface being ground or damage the polisher’s
motor.
4. Use of polishing compound or wax
Depending on the finishing degree of the surface, use the polishing compound or wax.
In order to attain the maximum polishing effect, first polish the surface with the fine sand
paper using the sander, then polish it with the polishing compound using the wool
bonnet, and then finish with wax. Apply a small quantity of the compound and wax to the
surface, and polish with the wool bonnet.
5. Beware of the cord during operation
CAUTION: Do not let the cord touch the wool bonnet during its operation, for the
rotating wool bonnet may catch the cord and roll it in.
6. Precaution after use
CAUTION: Do not lay the polisher down immediately after using on a place where there
are many shavings, much dirt and dust until it has completely stopped
revolving.
If the polisher is laid down with the wool bonnet turned downward before
it has completely stopped revolving, there is a risk that the material may be
damaged and the polisher may run wild, resulting in injury.
