MAINTENANCE

! WARNING

For your own safety, turn the switch OFF and remove the plug from the 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.
