Tensioning & Replacing V-Belts - Grizzly G0773 Owner's Manual

Tensioning &
Replacing V-Belts
V-belts stretch and wear with use, so it is impor-
tant that tension is routinely checked and adjusted
as needed. Improperly tensioned V-belts will slip
or poorly transmit power from the motor. We rec-
ommend checking the tension on a monthly basis
to ensure optimal power transmission. Replace
the V-belt if it becomes cracked, frayed, or glazed.
Keep belts and pulleys clear of exposure to oil,
grease, or cutting fluids that will cause them to
slip.
