Mounting Jaws
1.Clean top and bottom jaws with mineral spir- its. When dry, apply a thin coat of ISO 32 or equivalent oil to the mating surfaces.
2.Place top jaws on bottom jaws so alignment rings (see example below) fit into alignment slots and screw holes are aligned.
Note: Make sure stamped numbers of chuck jaw guide, bottom jaw, and top chuck corre- spond with each other to ensure jaws safely and evenly grip workpiece.

3.Apply a thin coat of ISO 32 or equivalent oil to cap screw threads to prevent screws from seizing under operational forces.
4.Thread the cap screws through the top jaws into the bottom jaws and finger tighten them, then back them off 1⁄4 turn.
5.Use chuck key to converge jaws to the center so they are evenly up against one another and even in height.
6.Fully tighten cap
7.Check jaw alignment. They should be evenly up against one another with no gaps and even in height.
The safety set screw under bottom jaw #4 (shown below) prevents the jaws from moving beyond safe engagement with the scroll gear. Unsecured jaws could fly off the chuck during operation resulting in serious personal injury to operator or bystanders. Always make sure this set screw is prop- erly installed and tightened when using the chuck.
