Additional clamping can be used, but may not be neces-
sary. Please be sure to exercise good judgment when securing
your vise to the mounting surface. Be sure your vise is secured
and will not move when applying the machine pressure.
Operating Instructions
For proper vise operation insert the handle on to the hex end of
the vise. Rotate clockwise to clamp and counterclockwise to un-
clamp your vise. This handle combined with the correct amount
of torque will provide you with all the clamping force you will
need to machine your parts. Air pressure is only used for clamp-
ing purposes 1/4" stroke maximum. All other operations remain
the same. A high quality calibrated torque wrench can be used if
needed. DO NOT use any other type of pressure to open or close
your vise.
The uses of handle extensions, air impact wrenches, breaker
bars or hammer strikes are not recommended and will void
the warranty if used. This will also cause damage to the thrust
bearing and screw threads. If you need more clamping force you
may need to upgrade the vise to a larger one.
To properly clamp a part in your Kurt vise you should place the
part in the center of the jaws resting on the ways of the vise.
Clamping only on one side or above the movable and stationary
jaws can result in jaw lift or loss of accuracy. (See Fig. on next
page)
If one-sided clamping is necessary you MUST use a dummy part
on the other side. When using parallels or step jaws you must se-
lect a size that keeps the bottom of the clamped part at or below
the top of the movable and stationary jaws. Always use jaw plates
for clamping. If jaw plates are not used damage to the mounting
surface of the movable and stationary jaw will occur. This will
result in reduced clamping accuracy and repeatability.
