Tensioning & Replacing Belt - Grizzly G0838 Owner's Manual

Changing Belt
Tensioning &
Replacing Belt
The drive belt stretches as the lathe is used.
Most of the stretching will occur during the first
16 hours, but may continue with further use. If the
lathe loses power while making a cut, the belt may
be slipping and need tensioning. If the belt shows
signs of excessive wear, or damage, replace it.
