Adjusting Quill Shaft Lock Screw - Grizzly T33903 Owner's Manual

Adjusting Quill Shaft
Lock Screw
While you may never have to adjust the quill shaft
lock screw (see Figure 66), you should under-
stand its function and know how to adjust it should
you ever need to remove the quill for cleaning.
This screw can prevent the quill from rotating or
from retracting into the headstock. If it is adjusted
incorrectly, the quill may lash or bind.
