Half Nut Adjustment; Fuse Replacement - Grizzly G0765 Owner's Manual

Half Nut Adjustment

The rigidity of the half nut engagement is adjusted
by tightening or loosening the half nut gib screws.
Adjust the half nut if it feels too loose or too tight
when being engaged. Movement that is too stiff
will accelerate wear. Movement that is too slop-
py will produce inaccurate turning or threading
results.

To adjust half nut:
1.
DISCONNECT LATHE FROM POWER!
2.
Disengage half nut.
3. Adjust gib set screws (see Figure 84) in
small, even increments so one end of gib
does not become tighter than the other.
