Servicing V-Belts

To ensure optimum power transfer from the motor to the blade, the V-belts must be in good condi- tion and operate under proper tension. Check belt tension at least every 3 months—more often if the bandsaw is used daily. V-belts stretch with use and must be periodically re-tensioned.

Replace the V-belts if they are cracked, frayed, or excessively worn.

Accessing V-Belts

1.DISCONNECT BANDSAW FROM POWER!

2.Open the lower wheel cover.

3.Remove the bandsaw blade.

4.Remove the lower wheel by removing the hex bolt at the center of the wheel, then sliding the wheel off the shaft. (The hex nut has left handed threads, so you must turn it clockwise to loosen it.)

5.Take off the pulley cover plate by removing the six Phillips head screws. You now have access to the V-belts for inspection or service (see Figure 43).

Checking V-Belts

1.Follow all previous instructions for Accessing V-Belts.

2.Push the center of each V-belt as illustrated in Figure 44, using moderate force. When tensioned correctly, the deflection should be about 14".

—If the deflection is more than 14", then ten- sion that V-belt (see Page 40) before doing Step 4.

3.Use a flashlight to inspect the belt.

—If a V-belt is cracked, frayed, or glazed, replace it as soon as convenient.
