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".

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.

— 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
