1. Check tension by depressing the belt upward at

the lower midspan of the pulleys with 14 Kg of

force. The belt should deflect 3–5 mm. If the

deflection is incorrect, go to the next step. If it is

correct, continue operation.

2. To adjust belt tension:

A. While holding the bolt (Fig. 31), loosen the

nut securing the idler pulley (Fig. 32)
