The polisher produces a counterforce which must be controlled by firmly holding onto the polisher. 2.

Switch OFF: Release the switch trigger. 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. English WOOL BONNET ASSEMBLY AND DISASSEMBLY WARNING: Never attempt to assemble or disassemble the wool bonnet while the polisher is capable of being turned “ON”. Be sure power switch is in the “OFF” position and the electrical cord has been disconnected from the receptacle. 1.
