When not in use, the Power tool should be kept in a dry place out of the reach of children.
4. Inspecting the carbon brushes (Fig. 4)
The Motor employs carbon brushes which are
consumable parts. When they become worn to
or near the "wear limit", it could result in motor
trouble. When an auto-stop carbon brush is
equipped, the motor will stop automatically. At
that time, replace both carbon brushes with
new ones which have the same carbon brush
Numbers shown in the figure. In addition, al-
ways keep carbon brushes clean and ensure
that they slide freely within the brush holders.
NOTE: Use HITACHI carbon brush number
indicated in Fig. 4
5. Replacing carbon brushes
Disassemble the brush caps with a slotted-head
screwdriver. The carbon brushes can then be
easily removed.
