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.
