BRUSH INSPECTION
AND REPLACEMENT
CAUTION: BEFORE INSPECTING THE BRUSHES,
DISCONNECT THE MACHINE FROM THE 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 nec-
essary. To inspect the brushes, proceed as follows:
1. Remove three screws (A) Fig. 47, and remove motor
cover (B).
3. Fig. 49, 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 serviceable after re-
moving, reinstall them in the same position as removed.
2. The brushes are located in the two holders (C) Fig. 48.
Remove spade type terminal connector (D) and pull out
brush holders (C).
