MAINTENANCE AND INSPECTION
1. Inspecting the tools
Since use of a dull tool will cause motor malfunctioning
and degraded e ciency, replace the tool with new ones
or resharpen them without delay when abrasion is noted.

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.

The motor unit winding is the very “heart” of the power

Exercise due care to ensure the winding does not
become damaged and/or wet with oil or water.
4. Replacing supply cord
If the replacement of the supply cord is necessary, it
has to be done by HIKOKI Authorized Service Center to
