Brush Reassembly

MAKE CERTAIN THAT THE GROUND WIRE IS SECURELY RECON-
NECTED TO THE GROUND TERMINAL IF REMOVED. LEADS,
INTERNAL TO THE SHIELD, MUST BE ROUTED AWAY FROM THE
ARMATURE, (E.G.: BE CLOSE TO THE INSIDE WALL OF THE ALU-
MINUM SHIELD) TO PREVENT A SAFETY HAZARD AND/OR DAM-
AGE TO THE MOTOR.

1.

Install the brush (pig-tail) terminal end under the
screw on the brush box in the same manner as the
old brush that was removed and tighten the screw.

2.

Slide the body of the brush into the brush box, be
certain that the wire (pig-tail) is aligned with the slot
in the base of the brush box so that it can "feed" into
the brush box slot as the brush wears down.

NOTE: The pig-tail wire should be formed to rest against the

nonmetallic insulator. It must be spaced from any
metallic surfaces other than the brush box by a mini-
mum of .125 in. (3mm).

3.

Now install the brush retaining spring bracket. Grasp
the tip of the spring bracket such that the roll-type
spring will be on the "brush side" of the brush box,
and resting on top of the brush when the brush
spring is completely installed.

4.

Push the spring bracket slowly into it’s slot while let-
ting it’s two attaching hooks slide on the wall of the
brush box.

5.

Stop, but do not release the spring bracket when it’s
hooks slip around the edge of the brush box.

6.

While still grasping the spring bracket with the pliers,
slowly bring the spring back out of the brush box
until the hooks latch around the edge of the brush
box.

7.

Now release the spring bracket and check that it is
lying flat against the brush box wall. If it is "cocked" it
is improperly seated and will have to be reinstalled.

IMPORTANT

THE SPRING BRACKET MUST BE ALSO LIE COMPLETELY INSIDE
THE BRUSH BOX AND NOT OUT OVER THE EDGE. THE ROLL END OF
THE SPRING MUST BE CENTERED ON THE TOP OF THE BRUSH.
(SEE CORRECT/INCORRECT BRUSH INSTALLATION ILLUSTRATION)

8.

Also apply slight pressure by pulling up on the
spring bracket to be certain it is hooked securely
around the brush box wall at the bottom of the brush
box.

9.

Screw the brush caps back into the end shield using
the largest possible screwdriver.

10.

Reinstall the drive motor(s) to the machine and
reconnect the power source.

IMPORTANT

NEW BRUSHES MAY BE SEATED BY RUNNING THE DRIVE MOTOR
AT NO LOAD. PROPER SEATING IS REQUIRED FOR LOWEST BRUSH
NOISE LEVEL.
