ADJUSTING TENSION

AND TRACKING OF

SANDING BELT

YOUR MACHINE IS SHIPPED

WITHOUT BELT TENSION APPLIED TO THE

SANDING BELT. BEFORE OPERATING THE

MACHINE IT IS VERY IMPORTANT TO INSURE THAT

THE BELT IS TRACKING CORRECTLY AND IT IS

PROPERLY TENSIONED. PROCEED AS FOLLOWS:

1. DISCONNECT MACHINE FROM

POWER SOURCE.

2. Loosen the two lock knobs (A) Fig. 37, and remove

the top cover (B).

Fig. 37

3. Turn the belt tension handle (C) Fig. 38, counter-

clockwise to increase belt tension. Correct tension is

determined by two things:

(1) The belt should be flat on the platen.

(2) The belt should be sufficiently tensioned to

prevent slipping on very heavy work. For ordinary work,

a tension just sufficient to take the curl out of the belt is

recommended.
