6.5 Belt Tension and Replacement
The belt tension should be occasionally checked when the band saw is new, as a new belt
may stretch slightly during the breaking-in process. If the belt becomes worn, cracked,
frayed or glazed, it should be replaced.
Please follow the steps to adjust the belt tension or belt replacement:
Fig. 16
Refer to Figure 16.
1. Disconnect the machine from the power source.
2. Remove the blade.
3. Loosen the four motor bracket mounting bolts (B) and loosen the belt tension adjustment
bolt (C).
4. Lift the motor and re-tighten the bolts (B) to hold the motor in the raised position.
5. Remove the lower wheel locking screw (A) on the back of the frame and remove the
lower wheel.
6. Remove the old belt and install the new one on the wheel belt pulley, making sure it
seats properly in the pulley grooves.
7. Slide the wheel back to the frame and tighten the wheel locking bolt (A). Then mount the
belt on the motor pulley.
8. Loosen the motor bracket mounting bolts (B) and allow the motor to lower.
9. The weight of the motor itself should generally produce the proper tension for the belt.
Check the tension by pushing with moderate pressure against the center of the belt. An
adequately tensioned belt will deflect about 1/2”. If the tension isn’t strong enough, push
down on the motor by tightening the belt tension bolt (C).
10. Re-tighten the motor bracket mounting bolts (B) and the belt tension bolt (C).
11. Re-check the blade tension and tracking before operating the saw.
