power source before maintaining

your saw.

GENERAL

An occasional coat of paste wax on the

work table will allow the wood being

cut to glide smoothly across the work

surface.

MOTOR

1. If the power cord is worn, cut

or damaged in any way, have it

replaced immediately by authorized

electrician.

2. Do not attempt to oil the motor

bearings or service the motor

internal parts.

REPLACING CARBON BRUSHES

(FIG. Z)

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.
