Maintenance
DANGER: Never put lubricants on the blade while it's spinning.
WARNING: To avoid injury from unexpected
starting or electrical shock, unplug the power
cord before working on the saw.
WARNING: For your safety, this saw is double
insulated+ To avoid electrical shock, fire or
injury, use only parts identical to those identi=
fled in the parts list reassemble exactly as orig-
inal assembly to avoid electrical hazards.
Replacing Carbon Brushes
The carbon brushes furnished wilt last approximately 50
hours of running time or t0,000 on/off cycles Replace
both carbon brushes when either has tess than 1/4"
length of carbon remaining To inspect or reptace first
unplug the saw Then remove the motor cap on the end
of the motor by removing 2 screws. Remove the lead
wires from the tabs on the brushes, then pull out the
brushes To reassemble reverse the procedure. Tighten
the screws snugly but do not overtighten,
NOTE: To reinstall the same brushes, first make sure
the brushes go back in the way they came out. This will
avoid a break in period that reduces performance and
increases wear,
Lower Blade Guard
Do not use the saw without the lower guard The lower
blade guard is attached to the saw for protection
Should the tower 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.,
WARNING: When cleaning lower guard unplug
the saw from the outlet to avoid unexpected
start-up.
Saw Dust
Periodically, sawdust will accumulate under the work
table and base This could cause difficulty in the move-
ment of the work table when setting up a miter cut.
Frequently biow out or vacuum up the sawdust
WARNING: If blowing sawdust, wear proper
eye protection to keep debris from blowing into
eyes,
