MAINTENANCE AND INSPECTION
WARNING: Be sure to switch power OFF and disconnect the plug from the
receptacle during maintenance and inspection.
1. Emptying and cleaning the dust bag
If the dust bag contains too much saw dust, dust collection will be affected. Empty the
dust bag when it gets full.

to the pad, replace the sanding paper as soon as excessive abrasion is noted.

screws be loosened, retighten them immediately.
