V-Belt Service; Tensioning Vertical Spindle V-Belts - Grizzly G0757 Owner's Manual

V-Belt Service

After approximately 16 hours of use, the V-belts
stretch slightly and seat into the pulleys. It is
important to check and adjust them to com-
pensate for this initial wear. Check the tension
thereafter on a regular basis. If the belts become
excessively worn or damaged, replace them.
All V-belts can be replaced by releasing the ten-
sion and rolling them off the pulleys, then rolling
the new belts back onto the pulleys.
Note: Replace the upper horizontal spindle
V-Belts as a matched pair. This will ensure even
wear and power transmission.
