V-Belts - Grizzly EXTREME Series Owner's Manual

V-Belts

V-belts will wear and stretch with extended use.
Maintaining proper tension of V-belts and making
sure they are in good condition will increase the
efficiency of the cutterhead and reduce wear on
the bearings.
When a V-belt can no longer be properly tensioned
or is cracked/damaged, replace both V-belts as a
matched set.
