the blade while it is spinning
.
MAINTENANCE
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. TT)
The carbon brushes furnished will last approximately 50 hours
of running time, or 10,000 ON/OFF cycles. Replace both
carbon brushes when either has less than 1/4 in. length of
carbon remaining, or if the spring or wire is damaged or
burned. To inspect or replace brushes, first unplug the saw.
Then remove the black plastic cap (1) on the side of the motor
(2). Remove the cap cautiously, because it is springloaded.
Then pull out the carbon brush (3) and replace. 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. Repeat for the
carbon brush located on the other side of motor.
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 motor performance and
increases wear.
LOWERING 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. Regularly
check to make sure the lower guard is working properly. Also
check before each use that all bolt/screws are tight. Clean
the lower guard of any dust or buildup with a damp cloth.
•
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 start-up
.
If need to remove small pieces of material from the table
cavity, see the section on Removing and Installing
the Table Insert on page 11.
To empty the dust bag, remove the sawdust bag from the
dust port. Open the zipper on the sawdust bag and empty
out the sawdust inside. Close the zipper and reinstall the
dust bag on the dust port as described on page 9.
LUBRICATION
(FIG. UU)
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; therefore, no further
lubrication is required.
Lubricate the following as necessary:
Chop pivot: Apply light machine oil to points indicated in
illustration.
Central pivot of plastic guard
: Use light household oil
(sewing machine oil) on metal-to-metal or metal-to-plastic
guard contact areas as required for smooth, quiet operation.
Avoid excessive 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.
