  Tighten each jaw in small increments. 
After you have adjusted the first jaw, 
continue tightening the remaining jaws 
in an opposing sequence, as shown by the 
sequential order in Figure 36.
6.
  After the workpiece is held in place by the 
jaws, use a dial indicator to make sure the 
workpiece is centered in the chuck.
— If the workpiece is not correctly centered, 
make fine adjustments by slightly 
loosening one jaw and tightening the 
opposing jaw until the workpiece is 
correctly positioned (see Figure 37 for an 
example).

Faceplate
Refer to the Chuck Installation (Page 38
and Chuck Removal (Page 39) instructions to 
install or remove the faceplate.
The faceplate included with your lathe can be 
used for a wide range of operations, including 
machining non-concentric workpieces, straight 
turning between centers, off-center turning, and 
boring.
The tools needed for mounting a workpiece will 
vary depending on the type of setup you have.
Machining non-concentric workpieces at a 
high speed could cause the workpiece to be 
thrown from the spindle with deadly force at 
the operator or bystanders. To reduce this 
risk, only machine non-concentric workpieces 
at low speeds and clamp counter-weights to 
the faceplate to balance it.
Failure to properly secure a workpiece to the 
faceplate could cause the workpiece to be 
thrown from the lathe with deadly force at the 
operator or bystanders. Use a minimum of 
THREE independent clamping devices to hold 
the workpiece onto the faceplate.
