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
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.
4. Replacing supply cord
If the replacement of the supply cord is necessary, it has
to be done by Hitachi Authorized Service Center to avoid
a safety hazard.
5. Maintenance of the motor
WARNING
Always wear protective goggles and dust respirators
when blowing air from the tail cover air hole with the use
of an air gun, etc.
Failure to observe this may result in ejected dust being
inhaled or entering your eyes.
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.
NOTE
When work has been fi nished, blow air containing no
moisture from the tail cover air hole with the use of an
air gun, etc., while running the motor without any load
applied. This is eff ective in removing any dirt and dust
that has accumulated. Dirt and dust collecting inside the
motor may result in malfunctions.
CAUTION
In the operation and maintenance of power tools, the
safety regulations and standards prescribed in each
country must be observed.
