GENERAL MAINTENANCE
Occasionally use a cloth to wipe off
chips and dust from the machine.
And oil the rotary parts once a month
to extend the tool life. Do not oil the
motor.
BRUSHE INSPECTION (FIG. 38)
Check the motor brushes after the rst
50 hours of use for a new machine or
after a new set of brushes have been
installed. After the rst check, examine
them every 10 hours of use.
When the carbon is worn to 6 mm in
length or if the spring or shunt wire
is burned or damaged, replace both
brushes. If the brushes are found
serviceable after removing, reinstall
them.
To inspect or replace brushes, rst
unplug the saw. Then remove the
black plastic cap (1) on the side of
the motor (2). Carefully remove the
spring-loaded cap. Then pull out the
brush and replace. Replace for the
other side. To reassemble, reverse the
procedure. The ears on the metal end
of the assembly go in the same hole
the carbon part ts into. Tighten the
cap snugly, but do not overtighten.
WARNING: For your own safety, turn
the switch off and remove the plug
from the power source outlet before
maintaining or lubricating your miter
saw.
WARNING! Always disconnect the
plug from the power source before
inspecting the brushes.
