2. Inspecting the carbon brushes (Fig. 35 and Fig. 36)
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. Check the carbon brushes after the first 50 hours of use for a new machine or after a new set of carbon brush have been installed. After the first check, examine them after each about 10 hours of use until such time that replacement is necessary.
When the carbon on either brush is worn to 3/16" (5 mm) in length or if either spring or shunt wire is burned or damaged in any way, replace both carbon brushes (see Fig. 35). If the carbon brushes are found serviceable after removing, reinstall them in the same position as before removed. 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. 36) with a slotted (minus) screwdriver.
