MAINTENANCE AND INSPECTION
1. Inspecting the depressed center wheel
Ensure that the depressed center wheel is free of cracks
and surface defects.
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. Inspecting the carbon brushes (Fig. 3)
The motor employs carbon brushes which are
consumable parts.
When they become worn to or near the “wear limit”, it
could result in motor trouble. When an auto-stop carbon
brush is equipped, the motor will stop automatically.
At that time, replace both carbon brushes with new ones
which have the same carbon brush numbers shown in
the
fi
gure. In addition, always keep carbon brushes clean
and ensure that they slide freely within the brush holders.
4. Replacing carbon brushes
Disassemble the brush caps with a screwdriver. The
carbon brushes can then be easily removed.
5. Replacing supply cord
If the supply cord of Tool is damaged, the Tool must be
return the cord to Hitachi Authorized Service Center for
the cord to be replaced.
6. 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.
