MAINTENANCE AND INSPECTION
1. Inspecting the blade
Continued use of a dull or damaged blade will result
in reduced cutting efficiency and may cause
overloading of the motor. Replace the blade with a
new one as soon as excessive 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
Authorized Service Center.
5. Replacing supply cord
If the supply cord of Tool is damaged, the Tool must
be returned to Hitachi Authorized Service Center for
the cord to be replaced.
