the pulleys.

Fig. 39

5. Jog the machine on and off to confirm the belt is

tracking properly. If the belt is leading to one side or the

other, very gently turn the tracking knob (E) Fig. 39,

clockwise to move the belt toward the adjusting screw

and counterclockwise to move the belt away from the

adjusting screw while jogging the machine on and off.

6. A final adjustment can be made with the motor

running. THIS ADJUSTMENT IS USUALLY VERY

SLIGHT. After the belt is tracking properly, disconnect

the machine from the power source, and replace the top

cover that was removed in STEP 2.

DEGREES TO BELT

1. DISCONNECT MACHINE FROM

POWER SOURCE.

2. Loosen the table tilting ratchet lever (A) Fig. 41,

rotate the stop (B) to the left, and rotate the table (C) Fig.

42 until the trunnion (D) Fig. 41 contacts the stop (B).

Tighten the lock handle (A). NOTE: The lock handle (A)

is spring-loaded and can be repositioned by pulling out

the handle, moving it, and letting it spring back into

position.

NOTE: After a long period of time, adjustments may

be necessary to maintain the tension and tracking of

the sanding belt. If the belt will not hold its tension,

tighten the set screw (G) Fig. 40. If the belt will not

hold its tracking, tighten the set screw (F) Fig. 40.

Make only small adjustments to these screws. Over-

tightening will lock the tension lever and/or the

tracking knob.

table to stop at the 45 degrees position.
