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 10 hours of use until such time that replacement is necessary.

The brush holders, one of which is shown at (A) Fig. 26, are located on the motor housing opposite each other. Fig. 27, illustrates one of the brushes removed for in- spection. When the carbon (B) on either brush is worn to 3/16" in length or if either spring (C) or shunt wire is burned or damaged in any way, replace both brushes. If the brushes are found serviceable after removing, re- install them in the same position as removed.

LUBRICATION

The gears in the gear box and the feed roller bushings should be lubricated periodically, as follows:
