burrs can be a problem, hone if necessary. If there are no
visible problems, the stud in question may need ad-
justment as follows:
• Remove the stop screw from the stud.
• If the cam marker in question can’t get to the rst Vee (3
o’clock), back the stud OUT one full turn, then replace the
stop screw.
• If the cam marker goes beyond the second Vee (6 o’clock),
screw the stud IN one more turn, then replace the stop
screw.
• If the markers are correctly aligned, repeat the tightening
sequence as step 3, light force. Repeat the sequence two
more times, rst with moderate force, then fully tighten.

TO REMOVE A CHUCK OR FACEPLATE
Disconnect the 220V supply from the lathe!
Protect the lathe bed, as Figure 3-23. While supporting its
weight, turn each of the cams to 12 o’clock, Figure 3-24, then
remove the chuck. If the chuck does not come free, try tapping
the backplate gently with a soft (dead blow) mallet.
