4. Inspecting the carbon brushes (Fig. 20)
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 planer with a carbon brush
which is worn in excess of the wear
limit will damage the motor.
NOTE: Use HITACHI carbon brush No. 21 indicated in Fig. 20.
5. Replacing carbon brushes:
Disassemble the brush caps (Fig. 1) with a slotted screwdriver. The carbon brushes can
then be easily removed.
6. 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.
