Brush Inspection And Replacement; Replacing Fuse - Delta 40-640 Instruction Manual

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 necessary.

The brush holders, one of which is shown at (A) Fig. 34,
are located on the motor housing opposite each other.
Fig. 35, illustrates one of the brushes removed for inspec-
tion. 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, reinstall them in the
same position as removed.
