Positioning Vise 

For Engravers and Jewelers Using a Microscope 

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. 

Hold the 

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.
