BRUSH INSPECTION AND REPLACEMENT

Disconnect machine from power source!

Brush life varies. It depends on the load on the motor. Check the brushes after the first 50 hours of use for a new

machine or after a new set of brushes has been installed. After the first check, examine them after about every 10

hours of use until replacement is necessary.

The brush holders, one of which is shown at (A) Fig. 34, are located on the motor housing opposite each other. One of

the removed brushes is illustrated in Fig. 35. When the carbon (B) on either brush is worn to 3/16" (4.8 mm) in length

or if either spring (C) or shunt wire is burned or damaged, replace both brushes. If the brushes are found serviceable

after removing, reinstall them.
