MAINTENANCE

WARNING

For your own safety, turn the switch OFF (O) 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. Y, Z)

To inspect or replace brushes, ﬁrst unplug the saw.

1. Remove the left side cover (1) by loosening the two

screws (2).

2. Remove the black plastic cap (3) on the side of the

motor (4).

3. Carefully remove the spring-loaded cap.

4. Pull out the brush and replace.

5. Replace for the other side by the hole (5-Fig. Z) on

the right side of the scroll saw.

6. 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.
