BRUSH INSPECTION
AND REPLACEMENT
BEFORE INSPECTING THE BRUSHES,
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.
To inspect the brushes, proceed as follows:
1. Lower the motor and tilt the arbor to 45 degrees.
2. One brush holder is shown at (A) Fig. 47B. (From
underneath the saw table.
3. Fig. 47C, illustrates the brush cap (A) and brush (B)
removed for inspection. When the carbon on the brush
(B) is worn to 3/16" in length or if either the spring 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.
4. To inspect the other brush, remove the table insert
and saw blade. The other brush is located 180 degrees
from brush (A) Fig. 47B.
