Operating Instructions
During Use
1
When using the polisher for long periods of time, check the polishing pad for wear.
2
Replace worn pads as worn or clogged pads will make the polisher inefficient.
3
The polishing operation will cause heat. Check the material that is being worked on that
it is not getting too hot. If this is occurring, stop polishing to allow the material to cool
down.
4
You can adjust the speed of the tool by adjusting the pressure you apply to the throttle.
5
Make regular checks on the polishing pad for wear and damage and replace them
immediately.
6
Due to the potential heat caused by the polishing process, keep flammable liquids and
gases well away from the work area.
