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 portable grinder 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. 5.
4. Replacing carbon brushes
Remove the brush caps (Fig. 1) with a slotted
screwdriver. The carbon brushes can then be easily
removed.
