To remove a chuck or faceplate:

Place a piece of plywood across the lathe
ways and position it just under the chuck.
The board should be at least 8" wide and 10"
long.
3. Turn a cam with the chuck key until the cam
lock mark aligns with the cam release datum
line shown in
Figure 16.
Chuck and Faceplate
Mounting
The Model G0600 is shipped with the 3-jaw chuck
installed. This is a scroll-type chuck, meaning that
all three jaws move in unison when adjusted.
The 4-jaw chuck, on the other hand, features
independent jaws. This chuck is used for square
or unevenly-shaped stock.
If either chuck cannot hold your workpiece, the
cast-iron faceplate has slots for T-bolts that hold
standard or custom clamping hardware. With the
correct clamping hardware, this faceplate will hold
non-cylindrical parts such as castings.
The chucks and faceplate have a D-8 Camlock
mount. Please note that there are lines stamped
into the cam and on the chuck body. A chuck key
is used to turn the locking cams (
Figure 16
) to
secure/unsecure the chuck/faceplate.
4. Unlock the other cams in the same manner.
Make sure to support the chuck as you align
the last cam. The chuck may come off at this
point, so
it is important that the weight is
supported by an adequate chuck cradle.
5. Remove the chuck key.
—If the chuck is still tight on the spindle,
tap the back of the chuck with a rubber or
wood mallet while supporting the bottom of
the chuck.
—If the chuck does not immediately come off,
rotate the spindle approximately 60˚ and
tap again. Make sure all the marks on the
cams and spindle are in proper alignment.
The chuck is heavy and is awkward to han-
dle. Always protect the ways when remov-
ing or installing a chuck, and make sure
that you make a support cradle
(
Figure
15 ) , lifting hoist, or that you have an assis-
tant when installing or removing chucks.
Ignoring this warning may lead to a severe
crushing or amputation injury!
