Tensioning/
Replacing Belts
The G0821 uses belts to drive the cutterhead and
the dust collection fan. When these belts are mis-
aligned, damaged, or not tensioned correctly, the
jointer will not function properly.
This sub-section describes how to service these
belts. You can order replacement belts from
Grizzly. The part number for the drive belt is
P0821072; the part number for the fan belt is
P0821091.
