Now that you have your new Kurt Vise, it’s time to set-up and begin using it.
You will see that your new vise comes with a Kurt swivel handle and chip
guard in the shipping carton (instruction manual available online at
www.kurtworkholding.com). The chip guard rests between the ways of the
vise and can be trimmed to size (see pg. 15) to help keep the chips away
from the screw. The handle is specifically designed to provide maximum
torque to your vise (clamping force provided below). Your vise should be
mounted to a clean, flat surface. The surface and the vise must be free of
any chips, dirt or debris of any kind. The mounting surface can be honed if
necessary. Clean the bottom of the vise with solvent or another cleaner if
needed.
To minimize vise bed deflection, clamp your Kurt vise to your machine table,
pallet, or sub-plate using the built-in clamping slots or through the body
holes provided.
Additional clamping can be used, but may not be necessary. 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.

HYDRAULIC OPERATING INSTRUCTIONS
The DX4H can be operated hydraulically by hooking up the Kurt 4" Hydraulic
Unit with a typical hydraulic pump or an air over hydraulic pump. Kurt offers
several solutions for hydraulic pumps, one being the KHP3 air over hydraulic
pump. Kurt offers other pump solutions and can be found on
kurtworkholding.com.
The hydraulic unit (KHU4) on the end of the DX4H has a 1/4 inch stroke.
The KHU4 can be used in both single and double acting applications. For
single acting, a spring will return the vise to the opened position when
hydraulics are disengaged. If double acting is desired, both ports on the
hydraulic unit will need to be hooked up to a pump (See figure 2).
C
CAUTION:
ALL NPT CONNECTIONS IN HYDRAULIC SYSTEM MUST UTILIZE
PIPE DOPE, NOT TEFLON TAPE. TEFLON TAPE CAN GET DISLODGED BY FLUID
AND END UP IN PUMP OR UNIT, POSSIBLY VOIDING WARRANTY.
