The brushes should be inspected frequently

WARNING: Be aware that the brush
can fly out of tool toward eyes when
opening the brush holder lock.
"With the cord unplugged, use thumb
pressure or small screwdriver to depress the
brush holder lock and rotate the holder
(right-side down and left-side up;) slowly to
prevent the brush and spring from ejffcting
out of the holder• While rotating the holder
slowly, you will begin to see the brush. Place
a finger over the brush while rotating the
holder, remove your finger slowly to reduce
the spring tension.
CAUTION: Do no_ force the brush holder to
rotate once you feel _t stop. To do so will
damage the tool.
If the brush is less than 1/8" long and the end
surface of the brush that contacts the
commutator is rough and/or pitted, they
should be replaced. Check both brushes.
Usually the brushes will not wear out
simultaneously. If one brush is worn out
replace both brushes, insert the spring
portion of the brush spring assembly into the
brush holder opening first. Make sure the
brushes are ins:ailed as illustrated. The
curved surface of the brush must match the
curvature of the commutator.
After replacing brushes the _ool should be
run at no-load; place it on a clean surface and
run it freely for 5 minutes before loading (or
using) the tool. This will allow the brushes to
"seat" properly and will give you more hours
of life from each set of brushes. Thiswill also
extend the total life of your tool since the
commutator surface will "wear _ longer.
