MAINTENANCE AND INSPECTION

WARNING:
1. Inspecting the driver bit
Since continued use of a worn driver bit will damage screw heads, replace the driver bit
as soon as excessive wear is noticed.
2. Inspection the drill bit
Continued use of a worn and/or damaged drill bit will result in reduced drilling efficiency
and may seriously overload the drill motor. Inspect the drill bit frequently and replace it
as necessary.
3. Inspecting the mounting screws
Regularly inspect all mounting screws and ensure that they are properly tightened.
Should any of the screws be loosened, retighten them immediately.
WARNING:
4. Maintenance of the motor
The motor unit winding is the very "heart"' of the power tool. Exercise due care to ensure
the winding does not become damaged and/or wet with oil or water.
5. Inspecting the carbon brushes
For your continued safety and electrical shock protection, carbon brush inspection and
replacement on this tool should ONLY be performed by a HITACHI AUTHORIZED
SERVICE CENTER.
