Chuck Jaw Reversal; 4-Jaw Chuck - Grizzly G0824 Owner's Manual

Chuck Jaw Reversal

This chuck has 2-piece jaws that consist of a
reversible top jaw and a master jaw. The top jaw
can be removed, rotated 180°, and re-installed in
the reverse position for additional work-holding
options. When reversing the top jaws, always
keep them matched with their original master jaw
to ensure the best fit.
To reverse 2-piece jaws:
1.
DISCONNECT MACHINE FROM POWER!
2.
Remove cap screws that secure top jaw to
master (bottom) jaw.
3. Remove top jaw, rotate it 180°, then re-install
it with longest cap screw in tallest portion of
jaw.
4. Repeat Steps 2–3 with each remaining jaw
(we recommend only reversing one jaw at a
time to keep all original parts together).

4-Jaw Chuck

Refer to the Chuck Installation or Chuck
Removal sections for instructions on installing or
removing the 4-jaw chuck.
The 4-jaw chuck features independently adjust-
able jaws for holding non-concentric or off-center
workpieces. Each jaw can be independently
removed from the chuck body and reversed for a
wide range of work-holding versatility.
Because of dynamic forces involved in
machining a non-concentric or off-center
workpiece, always use a low spindle speed
to reduce risk of workpiece coming loose
and being thrown from lathe, which could
cause death or serious personal injury.
Mounting Workpiece
1.
DISCONNECT MACHINE FROM POWER!
2.
Use an appropriate device to protect ways
(refer to Chuck Safety & Support Devices
section for more details).
3.
Use chuck key to open each jaw so work-
piece will fit into spindle opening and lay flat
against chuck face and jaw steps.
4.
With help from another person or a holding
device, position workpiece so it is centered in
chuck.
