MAINTENANCE AND INSPECTION

WARNING:
1. Inspecting the screws
Regularly inspect all screws and ensure that they are fully tightened. Should any of the
screws be loosened, retighten them immediately.
WARNING:
2. Confirm that there is no damage in the cord
and the housing, etc.
Furthermore, confirm that there is no abnormality in
the activation of the switch.
3. Inspecting the carbon brushes (Fig. 5)
The motor employs carbon brushes which are
consumable parts. Replace the carbon brush with a
new one when it becomes worn to its wear limit.
Always keep carbon brushes clean and ensure that
they slide freely within the brush holders.
CAUTION: Using this polisher with a carbon brush
which is worn in excess of the wear limit
will damage the motor.
NOTE: Use HITACHI carbon brush No. 43 indicated in Fig. 5.
Replacing carbon brushes:
Remove the brush caps (Fig. 1) with a slotted screwdriver. The carbon brushes can then
be easily removed.
4. Service and repairs
All quality power tools will eventually require servicing or replacement of parts because
of wear from normal use. To assure that only authorized replacement parts will be used,
all service and repairs must be performed by a HITACHI AUTHORIZED SERVICE CENTER,
ONLY.
