Yost Vises 7WW-DI, Manual

 
Step 4:  Place item between the serrated jaws of the vise.  
 
Step 5:  Close the vise by turning the vise handle clockwise until the item is snug 

between the serrated jaws.   

 
Step 6:  Continue to tighten the screw handle until you can no longer move (twist) the 

clamped item.   Do not over tighten as this may damage item and / or the vise. 

 
Step 7:  When finished working on the item, slowly turn screw handle counterclockwise

Swivel Base Operation 

 
The vise is generally operated perpendicular to the workbench, enabling work to be 
performed from either side of the vise.  In some cases, the vise may need to be rotated to 
allow better and safer access to the item.  In order to change the position of the vise, 
please follow the steps below:  
 
Step 1:  After item is securely mounted in the vise, slowly loosen each lockdown located 

on both sides of the vise.  Care should be taken not to over-loosen or remove the 
lockdowns as this may cause the vise to tip over and cause great bodily injury.  
Loosen (turn counterclockwise) each lock down about ¼ of a turn until the vise 
is able to swivel from the base.  

 
Step 2:  Swivel the vise to allow better and safer access to the item. 
 
Step 3:  Tighten (turn clockwise) each lockdown so that the vise is securely clamped to 

the base.
