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. 10) 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
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. 2 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.

Maintenance Schedule
It is very important to perform regular maintenance on your Kurt vise to
ensure proper operation. Improper maintenance will result in poor vise
performance and may void your warranty.
Daily/ Weekly
1. Remove chips from surface of vise.
2. Visually inspect seals for damage and cleanliness.
3. Visually inspect for chip entrapments and remove when necessary.
4. Air-dry and apply rust inhibiting oil to the machined surface of the vise.
Monthly
MAINTENANCE SCHEDULE
1. Open the vise to the maximum opening.
2. In the back of the movable jaw (handle end, center hole) loosen the
socket head set screw (approx. 6 turns). With the hex key (Allen wrench) in
the set-screw socket, lift up and forward to pivot the Jaw off of the vise
bed.
3. Slide the Jaw slightly toward the stationary jaw and lift up to remove the
jaw from the “beak” of the nut.
Note: A spherical segment (shaped as ½ of a steel ball) is inside the cavity
of the movable jaw and may fall out as the jaw is removed. Take care not
to lose or misplace the spherical segment.
4. Turn the movable jaw over and clean the inside cavity. Also clean the
spherical segment.
5. Remove chips, clean and apply a light coat of machine oil to the machined
surface of the following item:
a. Nut & Screw assembly (clean exposed threads on the screw)
b. Bed of vise (top of “rails”)
c. Inside of the vise between the center ways.
6. To re-assemble the movable jaw, apply a “glob” of grease to the under
side of the movable jaw in the pocket. Place the spherical segment in the
mating pocket and push into the grease. The grease will hold the segment
in place when the jaw is turned over to replace.

16MAINTENANCE SCHEDULE
7. Tip the jaw so the front of the jaw (the side with the jaw plate) is on the
vise bed. Lower the jaw on to the bed so that the segment contacts the
hook part of the nut and rest the jaw on to the vise bed.
8. Tighten the setscrew to firmly contact the nut. Back off the setscrew ¼
turn (approx.).
Note: DO NOT leave the setscrew tightened firmly to the nut as this may
cause improper operation. The movable jaw is designed to move slightly
(pivot side to side) so maximum jaw plate contact is maintained when
clamping out-of-parallel, sawed, or cast parts.
9. Your vise is now ready for use. Open and close your vise to check
for proper operation. Center the part to be clamped in the vise and close.
Your parts should be centered from side to side to ensure proper
clamping.

MAINTENANCE SCHEDULE
1. Open vise to maximum opening.
2. Loosen the set-screw and remove the movable jaw.
3. Remove spiral-retaining ring from handle end of the vise screw.
4. Remove the screw support from the vise body.
5. Remove the two-piece locking collar by removing the six SHCS.
6. With one screw still half-way out spin off the first collar.
7. Using a pin or screw, reach into the second collar and spin it off to
expose the bearings.
8. Remove the bearing pack assembly consisting of (2) thrust washers and
(1) thrust bearing from the counter bore in the end of the body.
9. Clean and inspect the counter bore, thrust washers, and thrust bearing.
10. Apply water resistant grease to the bearing (i.e. marine grade grease)
11. Install bearing pack assembly on the screw in the reverse manner.
12. Install the first collar by threading the screw until it stops. (See Fig.10)
13. Install the second collar behind the first and thread on until it stops. At
this point, the screw holes may or may not be lined up.
14. Turn the second collar counterclockwise until a hole lines up.
15. Then turn the collar back THREE (3) more screw holes. This will allow
proper seperation for the collar sections to lock on the threads and keep
the bearings firmly in place. (See Fig. 10)
16. Install the six SHCS and make tighten in a star pattern.
17. Install the screw support in the body on the screw (Hex end) and secure
using the spiral retaining ring.
18. Your vise is now ready to use.
