MAINTENANCE
DANGER
To avoid injury, never put lubricants on the
blade while it is spinning.
WARNING
• To avoid fire or toxic reaction, never use
gasoline, naphtha acetone, lacquer thinner or similar
highly volatile solvents to clean the miter saw.
• To avoid injury from unexpected starting or electrical
shock, unplug the power cord before working on the saw.
• To avoid electrical shock, fire or injury, use only parts
identical to those identified in the parts list.
Reassemble exactly as the original assembly to avoid
electrical shock.
REPLACING CARBON BRUSHES (FIG. GG)
The carbon brushes furnished will last approximately 50 hours
of running time, or 10,000 ON/OFF cycles. Replace both car-
bon brushes when either has less than 1/4 in. length of car-
bon remaining, or if the spring or wire is damaged or burned.
To inspect or replace brushes, first unplug the saw. Then re-
move the black plastic cap (1) on the side of the motor (2).
Remove the cap cautiously, because it is springloaded. 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 fits into.
Tighten the cap snugly, but do not overtighten.

MAINTENANCE
LOWER BLADE GUARD
Do not use the saw without the lower blade guard. The lower
blade guard is attached to the saw for your protection. Should
the lower guard become damaged, do not use the saw until the
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 buildup with a damp cloth.
CAUTION: Do not use solvents on the guard. They could
make the plastic “cloudy” and brittle.
WARNING
• When cleaning the lower guard, unplug
the saw from the power source receptacle to avoid
unexpected startup.
LUBRICATION (FIG. HH)
All the motor bearings in this tool are lubricated with a
sufficient amount of high grade lubricant for the life of the
unit under normal operating conditions; the refore, no further
bearing lubrication is required.
Lubricate the following as necessary: Chop pivot: Apply light
machine oil to points indicated in illustration.
Chop and central pivot: Use light household oil (sewing ma-
chine oil) on metal-to-metal or metal-to-plastic guard contact
areas as required for smooth, quiet operation. Avoid exces-
sive oil, to which sawdust will cling.
WARNING
Wear proper eye protection to keep debris
from entering eyes when removing sawdust from unit.
SAWDUST
Periodically, sawdust will accumulate under the work table
and base. This could cause difficulty in the movement of the
worktable when setting up a miter cut. Frequently blow out or
vacuum up the sawdust.
To empty the dust bag, remove the sawdust bag from the
dust collection port. Open the zipper on the sawdust bag and
empty out the sawdust inside. Close the zipper and reinstall
the dust bag as described on page 8.

NOTE: To reinstall the same brushes, first make sure the
brushes go back in exactly the way they came out. This will
avoid a break-in period that reduces motor performance and
increases wear.
