Tensioning/Replacing V-Belts - Grizzly G0782 Owner's Manual

Tensioning/
Replacing V-Belts
V-belts stretch and wear with use, so check the
tension after the first three months and then every
six months to ensure optimal power transmission.
Replace all of the V-belts as a matched set if any
of them show signs of glazing, fraying, or crack-
ing.
