MAINTENANCE AND INSPECTION
WARNING: Be sure to switch power OFF and disconnect the plug from the
receptacle during maintenance and inspection.
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: Using this router with loosened screws is extremely dangerous.
2. Inspecting the carbon brushes (Fig. 17)
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 router 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. 17.
3. Replacing carbon brushes
Remove the brush caps with a slotted
screwdriver. The carbon brushes can then
be easily removed. (Fig. 18)
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.
