4. Inspecting the carbon brushes (Fig. 19)
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,
always keep carbon brushes clean and ensure that
they slide freely within the brush holders.
5. Replacing carbon brushes
Loosen the two set screws and remove the tail cover.
Remove the brush caps and carbon brushes. After
replacing the carbon brushes, tighten the brush caps
securely and install the tail cover with securely
tightening two set screws.
