Introduction
Thank you for purchasing a Kurt vise. The Versatile Lock
3800-Series AngLock vise has a time proven design and
the outstanding accuracy of this product is second to none.
Backed by a lifetime warranty, this product will last many
years when used and maintained properly.
The original Kurt Anglock vises are designed for precision
clamping. The“Pull-type” action of the 3800 Versatile Lock design
reduces stationary jaw deection by at least 80%. This vise
has a one-piece body and stationary jaw design which reduce
weight and increases strength while providing .0005 clamping
repeatability. It oers ultra-high precision through many
important features. Features include: Ground sides that allow side
mounting, upright and back to back mounting, using the body
through holes allows side by side mounting.
With four dierent models including standard and reverse in both
manual and hydraulic conguration these vises are truly versatile.
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 & case hardened jaw
plates, semi-hard steel screw.
Introduction

Installation & Assembly Guide
Now that you have your new Kurt 3800-Series vise, it’s time to set-up
and begin using it. You will see that your new vise comes with a Kurt
swivel handle, two chip guards (short & long)supplied in the shipping
carton. The chip guard rests between the ways of the vise and can
be trimmed to size to help keep chips out of the screw. The handle is
specically designed to provide maximum torque to your vise. Your
vise should be mounted to a clean at 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 other cleaner if needed.
To minimize vise bed deection, clamp your Kurt vise to your machine
table, pallet, or sub-plate using the built-in clamping slots provided. To
access the through holes, simply pick the edge of the protective cap
up and expose the counter bored hole. Replace the cap after you have
mounted the vise to keep debris out of the holes. If you are mounting
the vise on it’s side or back to back, other clamping methods may be
required.

Operating Instructions
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 place the handle on to the hex end of
the vise. Rotate clockwise to clamp and counterclockwise to un-
clamp your vise. is handle combined with the correct amount
of torque will provide you with all the clamping force you will
need to machine your parts. 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.
e uses of handle extensions, air impact wrenches, breaker
bars or hammer strikes are not recommended and will void the
warranty if used. is will also cause damage to the thrust bear-
ing and screw threads. If you need more clamping force you may
need to upgrade to 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 li 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,the mounting surface of
the movable and stationary jaw will be damaged. is will result
in reduced clamping accuracy and repeatability.

Maintenance Schedule
It is very important to perform regular maintenance on your
Kurt vise to assure proper operation. Improper maintenance
will result in poor vise performance and may void your war-
ranty.
Daily/ Weekly
1. Remove chips from surface of vise.
2. Visually inspect for chips, 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 sur-
face of the vise.
Monthly
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 li up and
forward to pivot the jaw o of the vise bed.
3. Slide the Jaw slightly toward the stationary jaw and li up to
remove the jaw from the “hook” 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 items:
a. Nut and Screw assembly (clean exposed threads on
the screw).
b. Bed of vise (top of “rails”)
c. Inside of the vise between the center ways.

13| ENLGISH
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 spheri-
cal segment in the mating pocket and push into the grease. e
grease will hold the segment in place when the jaw is turned over
to replace.
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 seg-
ment contacts the hook part of the nut and rest the jaw on to the
vise bed.
8. Tighten the setscrew to rmly contact the nut. Back o the
setscrew ¼ turn (approx.) note: DO NOT leave the setscrew tight-
ened rmly to the nut as this may cause improper operation. e
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
insure proper clamping. (See Fig. below)

14 ENGLISH |
3 to 6 months
1.Open vise to maximum opening.
2.Loosen 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 four
SHCS.
6.With one screw still half way out spin o the rst collar.
7.Using a pin or screw reach into the second collar and spin it
o exposing the bearings.
8.Remove the thrust bearing 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 thrust washer (i.e. marine
grade grease)
11.Install thrust bearing assembly on the screw in the reverse
manner.
12.Install the rst collar by spinning on the screw until it
stops. (Items 12-14—See Fig. 1)
13.0Install the second collar behind the rst and spin 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| ENLGISH
15.en turn the collar back TWO (2) more screw holes. is
will allow proper distance for the collar to lock on the
threads and keep the bearings rmly in place. (Items
15-16—See Fig. 2)
16.Install the four SHCS and tighten.
17.Install the screw support in the body on the screw (Hex
end).
18.Your vise is now ready to use.

Troubleshooting Tips
The Kurt 3800-Series vise will operate trouble free for many years, if
properly maintained. This product is indestructible. In some cases it
will be necessary to troubleshoot. Use the information below to help in
the process.
Problem: My vise turns hard.
Tip: As a new vise the brush seal could be sti. Allow for break in of
vise.
Tip: As a used vise, it could be led with chips and threads could be
jammed. Properly clean and grease vise.
Problem: The collar comes o.
Tip: Retighten the four SHCS that hold it on. Proper adjustments need
to be made. See the 3-6 month maintenance schedule.
Problem: The handle support is loose or comes o.
Tip: You may need a new retaining ring. This support will oat, this is
normal. Install a new snap ring if needed.
Problem: My vise will not turn in either direction.
Tip: The vise is jammed with debris. Disassemble and clean as needed.
Problem: My vise won’t hold tolerance.
Tip: You may be experiencing jaw lift from clamping too high or on
one side of the jaw. Lower the part in the vise jaw and clamp more
material.
