Operating Instructions
⚠WARNING
Never use a hammer, pipe extension, or cheater bar on the spindle handle of a vise.
Never unscrew the moveable jaw beyond the maximum specified opening of the vise.
Never use a vise as a press for assembly or disassembly of objects.
1. Turn the spindle screw by rotating counter-clockwise to open the jaws and place the work piece
between them.
2. Loosen the lock-down nuts and rotate the vise to the best orientation for the job. A choice of three
jaws are available: straight jaws, pipe jaws, or V-jaws. Tighten the locking bolt to secure the vise
before starting any work.
3. Close the jaws until the work piece is held securely. Do not overtighten the jaws. Overtightening
the jaws could damage the work piece. The position of the jaws will lock after the handle is
tightened.
