operation
OPERATING INSTRUCTIONS
For proper vise operation insert the handle onto the hex of the 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. 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 central holding block and screw
threads. If you need more clamping force you may require a larger vise.
To properly clamp a part in your Kurt vise you should place the part in
the center of the jaws. Clamping only on one side can result in loss of
accuracy. If one-sided clamping is necessary you MUST use a dummy part
on the other side.
