Reversible Jaw Instructions | ENGLISH
Reversible Jaw Instructions
The DTR10 and DTR20 have a reversible movable jaw. The DT20 vise
does not. Follow the directions below to reverse the jaw.
1. Loosen the set screw in the part of the movable jaw that
protrudes through the stationary jaw. This set screw retains the
movable jaw to the stationary jaw.
2. Back the screw out until the movable jaw is free from the
stationary jaw.
3. Remove the protective plug assembly from the other side of the
stationary jaw.
4. Insert the movable jaw and screw on the other side of the vise.
5. Tighten the set screw in the movable jaw so that it is retained
again.
6. Insert the protective plug into the other side of the stationary
jaw.
Note:
The set screw that retains the movable jaw pushes a ball into a cavity in
the stationary jaw. If the set screw is tightened too hard, the ball can get
stuck in that cavity. The set screw should be tightened to firmly push
the ball into the cavity and then backed off about 1/4 turn. When
loosening the set screw and removing the movable jaw, be careful not
to lose the ball.

Troubleshooting | ENGLISH
Troubleshooting
Use the information below to help in troubleshooting.
Problem: The vise is difficult to turn.
-If it is a new vise,the brush seal could be stiff. Allow for break in of
vise.
-If it is a used vise, it could be filed with chips. Clean and grease the
screw.
Problem: The vise will not turn in either direction.
-The vise is rusted or jammed with debris. Disassemble and clean as
needed.
Problem: The jaw is lifting.
-Recut the dovetail with Kurt's dovetail cutter.
-Check to see that the torque limits are not being exceeded. (see pg 3)
Problem: The hole pattern on the base does not match the table it is
being mounted to.
-Kurt can provide a schematic of the hole pattern to help make a
fixture plate.
-Kurt sells an adapter plate (BP8) that will allow the vise to be adapted
to almost any machine table.
