The correct alignment of the motor and lower wheel pulleys helps to ensure correct and even tension of the V-belts, proper power transmission, and reduced V-belt heat and wear during opera- tion.

Remove the rear motor access panel, and use a straightedge across both pulleys, as shown in Figure 41, to check the pulley alignment.

If necessary, loosen the fasteners securing the wheel pulley to the shaft, align the wheel pulley with the motor pulley, then re-tighten the fasteners for both pulleys.

Tensioning V-Belts

Tools Needed:	Qty

To ensure optimum power transfer from the motor to the blade without slipping, the V-belts must be in good condition and operate under proper ten- sion. Check V-belt tension at least monthly—more often if the bandsaw is used daily. V-belts stretch with use and must be periodically re-tensioned.

To check/tension/replace the V-belts:

1.DISCONNECT BANDSAW FROM POWER!

2.Remove the rear motor access panel.

3.Make sure the motor and lower wheel pulleys are correctly aligned.

4.Push the center of each V-belt as illustrated in Figure 42, using moderate force. When tensioned correctly, the deflection should be about 3⁄4".

—If the deflection is correct and the V-belts are in good condition, no further action is required. Replace the rear motor access panel.

—If the deflection is more than or less than 3⁄4" or the V-belts need to be replaced, then continue with the next steps.
