3. Inspecting the carbon brushes (Fig. 39 and Fig. 40)
The carbon brushes in the motor are expendable parts.
If the carbon brushes become excessively worn, motor trouble might occur.
Therefore, inspect the carbon brushes periodically and replace them when they have become worn to
the wear limit line as shown in Fig. 39.
Also, keep the carbon brushes clean so that they will slide smoothly within the brush holders.
The carbon brushes can easily be removed after removal of the brush caps (see Fig. 40) with a slotted
(minus) screwdriver.
