MAINTENANCE

A DANGER

naphtha acetone, lacquer thinner or similar highly

volatile solvents to clean the miter saw.

A WARNING

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.

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.

A WARNING

When cleaning the lower guard, unpiug the saw from

the power source receptacle to avoid unexpected

startup.

SAWDUST

Periodically, sawdust will accumulate under the work

table and base. Frequently blow out or vacuum up the

sawdust.

A WARNING

If blowing sawdust, wear proper eye protection to

keep debris from blowing into eyes.

REPLACING CARBON BRUSHES (FIG. CC)

Replace both carbon brushes when either has less

than 1/4in. 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.

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. CC

LOWER BLADE GUARD

Do not use the saw without the lower blade guard.

The lower blade guard is attached to the saw for your

LUBRICATION

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.
