MAINTENANCE AND INSPECTION

WARNING:
1. Inspecting the screws
Regularly inspect all screws and ensure that they are properly tightened. Should any of
the screws be loosened, retighten them immediately.
WARNING:
2. Inspecting the carbon brushes (Fig. 7)
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 electronic sander polisher with a carbon brush which is worn in
excess of the wear limit will damage the motor.
NOTE: Use HITACHI carbon brush No. indicated in Fig. 7.
Replacing carbon brushes:
Remove the brush caps (Fig. 1) with a slotted screwdriver. The carbon brushes can
then be easily removed.
3. Cleaning lock pin section
If the lock pin section becomes dirty, clean it at once.
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.
5. Service parts list
CAUTION: Repair, modification and inspection of Hitachi Power Tools must be carried
out by an Hitachi Authorized Service Center.
This Parts List will be helpful if presented with the tool to the Hitachi
Authorized Service Center when requesting repair or other maintenance.
In the operation and maintenance of power tools, the safety regulations
and standards prescribed in each country must be observed.
