Tensioning Return Spring - Grizzly G0823 Owner's Manual

Tensioning Return
Spring
The spring tension for automatic quill recoil has
been pre-set at the factory. It should not need
adjustment under most normal circumstances. If
it does need adjustment, the spring housing is
located on the left side of the headstock.
If the return spring should
come loose from the spring
cap and rapidly unwind,
laceration or impact inju-
ries could occur. Always
wear heavy leather gloves
and safety glasses when
adjusting the return spring
tension.
