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.

Fig. II

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.

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.

MAINTENANCE

To avoid injury, never put lubricants

on the blade while it is spinning.

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.

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.
