seated brush, or brushes with
excessive side play.

Remedy
Brushes should be a free fit in
in the brush boxes without
excessive side play.
Binding brushes and brush
boxes should be wiped clean
with a gasoline (undoped)
moistened cloth. A new brush
should be run in until at least
50 percent seated; however, if
facilities are not available for
running in brushes, then the
brush should be properly
seated by inserting a strip of
number 000 sandpaper
between the brush and com-
mutator, with the sanded side
next to the brush.
Pull sandpaper in the
direction of rotation, being
careful to keep it in the same
contour as the commutator.
— CAUTION —
DO NOT USE COARSE
SANDPAPER OR EMERY
CLOTH. AFTER SEATING,
CLEAN THOROUGHLY TO
REMOVE ALL SAND AND
METAL PARTICLES TO
PREVENT EXCESSIVE
WEAR. KEEP MOTOR
BEARING FREE FROM SAND
OR METAL PARTICLES.
