JETYD Operations Manual 

Dual Speed jGun  

The dual speed jGun is the newest implementation of our pneumatic torque wrenches. It gives a 
user the ability to select whether they want to run the tool with high speed or with maximum 
torque. Physically, the dual speed gun is identical to the standard jGun with the exception of a 
handle which guides the shifting mechanism.

The handle shown above can be positioned on either side for right or left handed operation.
