Replacing/Tensioning Belt - Grizzly G0813 Owner's Manual

Replacing/
Tensioning Belt
To ensure optimum power transmission from the
motor to the cutterhead, the belt must be in good
condition (free from cracks, fraying and wear) and
properly tensioned. After the first 16 hours of belt
life, re-tension the belt, as it will stretch and seat
during this time.
