Checking V-Belt

To ensure optimum power transmission from the motor to the blade, the V-belt must be in good condition and operate under proper tension. The belt should be checked for cracks, fraying, and wear. Belt tension should be checked at least every 3 months—more often if the bandsaw is used daily.

To check the V-belt:

1.DISCONNECT BANDSAW FROM POWER!

2.Open the lower wheel cover.

3.Push the center of the V-belt. Note the amount of deflection.

—If deflection is more than 3⁄4", tighten the V-belt.

4.Note the condition of the V-belt.

—If the V-belt is cracked, frayed, or glazed; it should be replaced as soon as conve- nient.

5.Hold the motor in position with one hand and tighten the motor adjustment screw with the other hand.

6.Push the center of the V-belt.

—If deflection is approximately 3⁄4" with mod- erate pressure from your thumb or finger (Figure 59), then the tension is correct.

—If the deflection is more than 3⁄4", repeat
