Positioning Vise
INSTRUCTIONS • #003-541

How To Position

Make sure the vise head is in the center
of the vise base. Place the vise directly in
the center under the microscope (FIG. 1).
Pressing the "Release Lever" will free
the vise head so that it may be moved or
slide in any desired direction. Release the
lever and the vise head locks in place and
will rotate from that desired point (FIG. 2).
Users will quickly learn to position the
vise while looking through the scope.

Maintenance

Based on usage, open jaws fully and clean any dirt and metal pieces
from the threads. After cleaning, apply a small amount of light oil to
the threads.

Wear Repair

Parts that may wear and eventually need replacing are the "Lock
Button" (FIG. 3.A) located at the center of the position release lever and
the "Jaw Thread Pins" (FIG. 8) located in each jaw.

Loss of Locking Tension

If the vise head does not stay in locked position, tighten the tension.
Loosen the Rotational Drag Screw located on the side of the ball
(FIG. 4). Lift the upper portion of the vise out of the base. Turn the vise
head upside down and rest it on its top.
Remove the four hex head bolts (FIG. 5) from the mounting plate and
lift the plate off. Set the bearing / post assembly (FIG. 6) to the side. The
lock button (FIG. 3.A) is now visible in the center of the lever handle.
Remove the lock button with a small screwdriver by prying it up.
The button should have a 3/32" flat in the center of the crown. If the
button is damaged or excessively worn, we recommend replacing
it. If it looks in good shape, you can add tension by placing shim
washers (FIG. 3.B) under the button. This will raise it to create more
locking tension.
Reassemble the vise by placing the bearing / post in the center
of the vise head as shown in Figure 6. Set the mounting plate
over the bearing/post and align the bolts.
Pull the release lever open to move the vise head. Hold it in
that position and then tighten the four bolts down.
lever open when tightening the bolts or damage to the lock
button will occur.
Place the vise head into the base and tighten the ball swivel
tension screw (FIG. 4).

Rotational Lock Replacement

The LOCK or DRAG PIN is subject to wear and may need replacement
after extended use. Simply remove the ball swivel tension screw with the
hex wrench. The Spring and Lock Pin should follow (FIG. 7). If not, turn
the ball until they fall out. Replace the Lock Pin (#003-046), Spring, and
Tension Screw.
