MAINTENANCE AND INSPECTION

WARNING:

Be sure to switch power OFF and disconnect the plug from the
receptacle during maintenance and inspection.

1. Inspecting the drill bits

Since use of a dull tool will cause motor malfunctioning and degraded efficiency,
replace the drill bit with a new one or resharpening without delay when abrasion
is noted.

2. Inspecting the screws

Regularly inspect all screws and ensure that they are properly tightened. Should
any of the screws be loosened, retighten them immediately.

WARNING:

Using this rotary hammer with loosen screws is extremely
dangerous.
