Step 4: Place item between the serrated jaws of the vise.
Step 5: Close the vise by turning the vise handle clockwise until the item is snug
between the serrated jaws.
Step 6: Continue to tighten the screw handle until you can no longer move (twist) the
clamped item. Do not over tighten as this may damage item and / or the vise.
Step 7: When finished working on the item, slowly turn screw handle counterclockwise
to release the item.
Swivel Base Operation
The vise is generally operated perpendicular to the workbench, enabling work to be
performed from either side of the vise. In some cases, the vise may need to be rotated to
allow better and safer access to the item. In order to change the position of the vise,
please follow the steps below:
Step 1: After item is securely mounted in the vise, slowly loosen each lockdown located
on both sides of the vise. Care should be taken not to over-loosen or remove the
lockdowns as this may cause the vise to tip over and cause great bodily injury.
Loosen (turn counterclockwise) each lock down about ¼ of a turn until the vise
is able to swivel from the base.
Step 2: Swivel the vise to allow better and safer access to the item.
Step 3: Tighten (turn clockwise) each lockdown so that the vise is securely clamped to
the base.
Reversing your vise
When reversing your vise, please follow these steps:
Step 1: Make sure vise is securely mounted to the workbench.
Step 2: Make sure the swivel base lockdowns are secure.
Step 3: Open the vise by turning the vise handle counterclockwise. While opening the
vise, have a secure grip on the bar of the vise to prevent it from falling. For additional
safety do one of the following:
• Rotate vise using swivel base so that the vise is over the work surface prior
to sliding out the front jaw or
• Use an adjustable table that is slightly lower than the work bench while
sliding the front jaw out of the back jaw of the vise.
Step 4: Once the screw is no longer engaged in the nut carefully remove the bar of the
vise while making sure to hold the bar of the vise securely.
