Brush Card Assemblies
NOTE:
There are two Brush Card Assembly designs.
On the original brush card design the red and black wires
that go to the switch are soldered on the brush card.
On the new brush card design the red and black wires
that go to the switch are secured to the brush card with
spring washers and screws.
The new brush card design is directly interchangeable
in tools that have the old brush card design.
Be sure carbon
brush is in brush tube
with brush shunt moving
freely in side groove of tube.
Place brush spring over post with short leg
positioned downward as shown. Be sure spring
is completely down with short leg trapped against
'Y' shaped wall on brush card.
While holding spring in place, bring the long leg of
spring over the brush tube and through rear opening
of tube. Position rounded hook of spring in groove on
back of carbon brush. Be sure to check for free move-
ment between carbon brush, brush shunt and brush spring.

NOTE:
As an aid to prevent damage to the armature
commutator or the brushes when removing and
installing the armature assembly, it is recommended to
pull the carbon brushes partially back into the brush
tube. The carbon brushes will be held in place with the
brush spring moving from the rear of the brush to the
side of the brush.
In the unlikely event that the spring pops off follow the
instructions below.
