!WARNING: Electrical wiring should be done by a qualified electrician. The machine must

be properly grounded to help avoid electrical shock and associated hazards including possible death.

ADJUSTMENTS

Before putting power to the sander, inspect the machine thoroughly. Check to ensure that all screws are tight, all mechanical functions work freely, belt runs freely and tracks properly, and the disc runs freely and does not come into contact with the guard or table.

Turn the motor on and check for proper rotation direction of the belts. The sanding belt should move from the idler pulley toward the drive pulley while the disc should rotate counter-clockwise with the operator facing the disc.

Run the sander without sanding for a short period to ensure the belt tracks properly and the disc adhesive sticks properly to the disc.

ABRASIVE BELT INSTALLATION

To install or replace an abrasive belt, proceed as follows (Figures 5 and 6):

1.Loosen the knob (A) and swing the belt end guard

(B) out of position.

2.Remove the side guard (C) by loosening and removing the two screws holding it. Release tension on the belt by loosening the tension knob (E) at the back of the belt arm. Loosen the tracking screw (F) on the side of the belt arm and move the drum forward.

3.Slide the worn sanding belt off the idler and driving drums and install a new belt.

4.Retighten the belt tension screw (E) and tracking screw (F). Check the tracking manually to ensure the belt tracks properly. Put the side guard (C) back on and secure with the screws. Swing the end guard (B) back into position and re-tighten the knob (A).

ABRASIVE BELT ALIGNMENT

1.To properly align the abrasive belt, tighten the belt tension screw (E) until the belt is relatively tight. See Figure 5.

2.Manually rotate the belt with one hand while at the same time adjusting the tracking screws with the other hand until the belt is tracking in the center of the idler and driving pulley. Caution is necessary since excessive tension can stretch a belt to the point where it will not track.
