BRUSH INSPECTION AND REPLACEMENT

Brush life varies, depending 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 every 10 hours of use until replacement is necessary. To inspect the brushes:

DISCONNECT THE MACHINE FROM THE POWER SOURCE.

1.Open the brush holders (A) Fig. 48, located on either side of the motor housing.

2.Remove the brushes (B) Fig. 49.

3.If the carbon on either brush is worn to 3/16" or if either spring or shunt wire is burned or damaged, replace both brushes.

4.If the brushes are serviceable, reinstall them.
