on the side of the motor (caution, this cap is spring
loaded by the brush assembly} Then pull out the brush.
Repeat for the other side To reassemble reverse the
procedure, The ears on the metal end of the brush
assembly go in the same hole the carbon part fits into
Tighten the cap snugly but do not overtighten
NOTE: To reinstaff the same brushes, first make sure
the brushes go back in the way they came out. This
wilt avoid a break in period that reduces performance
and increases wear
Lower Blade Guard
Do not use the saw without the lower guard, The Iower
blade guard is attached to the saw for protection, Should
the lower guard become damaged, do not use the saw
until damaged guard has been replaced, Develop a
regular check to make sure the lower guard is working
properly, Clean the lower guard of any dust or build up
with a damp cloth,
CAUTION: Do not use solvents on the guard, They
could make the plastic "cloudy" and brittle.
