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.
Remove the dust bag, open the fastener, and dispose of the contents.

Since use of worn-out sanding paper will degrade efficiency and cause possible damage
to the pad, replace the sanding paper as soon as excessive abrasion is noted.

Regularly inspect all screws and ensure that they are fully tightened. Should any of the
screws be loosened, retighten them immediately.
WARNING: Using this random orbit sander with loosened screws is extremely
dangerous.
