!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,

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.

unplug the power cord before

working on the saw.

● For your safety, this saw is

double-insulated. 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. II)

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 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.

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.

!WARNING

●When cleaning the lower guard, unplug the saw from the power source receptacle to avoid unexpected startup.

●Do not use solvents on the guard. They could make the plastic “cloudy” and brittle.
