Checking And Tensioning V-Belts - Grizzly G0636X Owner's Manual

Checking and
Tensioning V-Belts
To ensure optimum power transmission from the
motor to the blade, the V-belts must be in good
condition and operate under proper tension. The
belts should be checked for cracks, fraying, and
wear. Belt tension should be checked at least
every 3 months—more often if the bandsaw is
used daily.
Tools Needed:
Ruler ...................................................................1
Hex Wrench 6mm ...............................................1
