Drive belt tension and
replacement
The drive belt and pulleys are properly adjusted at
the factory. However, 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 as follows:
Refer to Figures 36 and 38.
1. Disconnect machine from power source.
2. Open upper and lower doors and remove blade.
3. Remove screw from lower wheel shaft and
remove lower wheel.
4. Loosen motor lock handle.
5. Raise motor lift handle and retighten motor lock
handle to hold motor in raised position.
6. Remove old belt and install new one, making
sure it seats properly in the pulley grooves.
7. Loosen motor lock handle and allow motor to
lower.
8. The weight of the motor itself should generally
produce the proper tension for the belt. Check
tension by pushing with moderate pressure
against center of belt (Figure 38). An
adequately tensioned belt will deflect about
1/2”. If tension isn’t strong enough, push down
on the motor.
9. Tighten motor lock handle, reinstall lower
wheel, and install hex nut securely on shaft.
10. Re-check blade tension and tracking before
operating saw.
