Belt Tension & Replacement - Grizzly G0899 Owner's Manual

Belt Tension &
Replacement
The drive belt stretches slightly as the saw is
used. Most of the belt stretching will happen dur-
ing the first 16 hours of use, but it may continue
through continued use. If you notice that the belt
is slipping, it will need to be tensioned. If the belt is
cracked, frayed, or shows other signs of excessive
wear, it will need to be replaced.
