BRUSH INSPECTION

AND REPLACEMENT

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. To inspect the brushes, proceed as follows:

DISCONNECT MACHINE FROM POWER

SOURCE.

1. Remove three screws (A) Fig. 46 and remove motor

cover (B).

3. Fig. 48 illustrates one of the brushes (E) removed

from the holder (C). When the carbon on either brush (E)

is worn to 3/16″ in length or if either spring (F) or shunt

wire is burned or damaged in any way, replace both

brushes. If the brushes are found to be serviceable after

re-moving, reinstall them in the same position.

2. The brushes are located in the two holders (C) Fig. 47.

Remove spade type terminal connector (D) and pull out

brush holders (C).
