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 fi gure.
In addition, always keep carbon brushes clean and ensure
that they slide freely within the brush holders.
5. Replacing carbon brushes
Loosen the screws (Hexagon socket hd. bolt M4×8) of
the cap covers, then remove the cap covers (Fig. 5). After
removing the brush caps, the carbon brushes can be
removed.
After replacing the carbon brushes, tighten the brush caps,
then mount the cap covers securely.
