,_ 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.

= 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. JJ)

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). Carefully remove the spring-

loaded cap. 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.

NOTE: When reinstalling the same brushes,

put them back in the way they came out. This

will avoid a break-in period that reduces motor

performance and increases wear.

SAWDUST

Periodically, sawdust will accumulate under the

worktable 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.

WARNING]

if blowing sawdust, wear proper eye protection

to keep debris from blowing

into eyes.

LUBRiCATiON

(FIG. KK)

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.

Link: (actuates lower guard movement) If down

chop motion is hard to start, oil link at two screws

(1).

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. Check

regularly to make sure the lower guard is working

properly. Clean the lower guard of any dust or

buildup with a damp cloth.
