V-belts are not correctly tensioned.
Proceed to Step 5.
Tensioning/Replacing V-Belts
To ensure optimum power transmission from the
motor to the blade, the V-belts must be properly
tensioned, and free of cracks, fraying, and wear.
Belt tension and condition should be checked at
least every 3 months—more often if the bandsaw
is used daily.
