Introduction
Thank you for purchasing a Kurt DX6 vise. You have just purchased one
of the best machine vises in the industry. The outstanding accuracy
of this product is second to none. Backed by a lifetime warranty, this
product will last forever when used and maintained properly.
The original Kurt Anglock vises are designed for precision clamping on
basic machine tools such as knee-type mills, grinders and machining
centers. They can be used for, but are not limited to, operations like
precision boring, drilling, tapping, grinding & nishing.
The patented Anglock design allows the movable jaw to advance in
such a way that each pound of force forward induces a ½ pound force
downward which minimizes the jaw lift and increases accuracy. This
combined with the needle bearings increases jaw clamping pressure.
Other features include: 80,000 psi ductile iron body, hardened vise bed
& jaw plates, semi-hard steel screw.

SET-UP INSTRUCTIONS
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. 14) 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.

OPERATING INSTRUCTIONS
HYDRAULIC OPERATING INSTRUCTIONS
The 3800H/3810H can be operated hydraulically by hooking up the Kurt 8"
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 (KHU8), on the end of the 3800H/3810H, has a 1/4 inch
stroke. The KHU8 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).

HYDRAULIC OPERATING INSTRUCTIONS
Jaw Positioning:
Once all plumbing is set up, it time to position jaws for hydraulic clamping.
1. Position jaws less than 1/4 inch from the part being clamped as is
shown in figure 3 above. This is done manually by putting the handle
onto the hex end and turning the screw until the jaws are in position.
2. Make sure the jaws are less than 1/4 inch from the part since the
hydraulic unit has only a 1/4 inch stroke.
3. The vise is now ready to have the hydraulics engaged for clamping
the part.
For basic hydraulic set-up instructions, go to the next page (pg. 7)

OPERATING INSTRUCTIONS
HYDRAULIC OPERATING INSTRUCTIONS
For Basic Hydraulic Set-Up:
1. Remove plastic caps from pressure and release ports on Hydraulic pump.
Install 90° fittings.
2. Remove plastic caps from pressure and release ports on hand or foot
valve. Install straight fitting.
3. Install straight fitting on the Hydraulic Unit (1/8 NPTF) of the 3800H vise.
4. A filter-lubricator-regulator combination is recommended to insure
clean air coming into the unit. See Clamping Force Chart for air pressure
required to attain desired clamping force (pg. 4 & 8).
5. Connect the FRL to the input air port on the KHP3 hydraulic pump.
6. Connect the hydraulic line to the hydraulic unit on the vise and then to
the output side of the hydraulic pump
7. If using a hand valve connect the 3-line cluster
8. Apply air pressure (80 PSI maximum) to system. Loosen swivel fitting at
vise and bleed air. Tighten fitting. Release air pressure.
9. Repeat previous step until all air is purged
10. System is now ready for use.
NOTE: For multiple vise hook-ups, call factory for recommendations.

MANUAL OPERATING INSTRUCTIONS
For proper vise operation, insert the handle on to the hex end of the
vise. Rotate clockwise to clamp and counterclockwise to unclamp 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. 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 require a larger
vise.
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. 5 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 select 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.
