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 new ones or resharpen them without
delay when abrasion is noted.

2. Inspecting the mounting screws

Regularly inspect all mounting screws and ensure
that they are properly tightened. Should any of the
screws be loose, retighten them immediately. Failure
to do so could result in serious hazard.

3. 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.

4. 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
