Multiquip FS3SP operation manual Belts and Pulleys

3.Check V-belt tension (Figure 18) by using a tensionmeter (6.0 - 9.0 lbs.) against the inside belt at a mid point between the two pulleys, or by deflecting the center belt at a mid point 3/8” (10 mm) - 1/2” (13 mm).

CORRECT V-BELT

TENSION 3/8 IN. (10 MM) TO 1/2 IN.(13 MM) WHEN DEPRESSED AT MIDPOINT AS SHOWN

Figure 18.V-Belt Tension

4.DO NOT over or under tension the V-belts. Severe damage can occur to the saw and engine crank shaft if the belts are over tensioned. A decrease of power to the blade and poor performance will result if the belts are under tensioned (loose on pulleys).

5.If theV-belts becomes worn or loose, replace them by using the following V-belt part numbers listed in Table 6.
