JETYD Operations Manual

jGun Overview
The jGun pneumatic torque wrench is designed to safely and accurately deliver up to 5,200 ft-lbs
of torque onto a fastener. This is accomplished using a patented planetary gearbox torque
multiplier system and an appropriate reaction arm or LoaDisc™ Reaction Washer. The torque
multiplier produces torque ratios of up to 700:1 while the reaction arm or washer is used to
absorb the high counter rotational force produced as the final torque value is reached. At final
torque value, the jGun safely stalls out, leaving the fastener tightened to specification.
Unlike impact wrenches, the jGun never transmits working torque to the operator. The torque is
applied between the fastener and the reaction surface.
This manual provides information for both the standard jGun and the dual-speed jGun.
jGun Safety
Only qualified personnel who have thoroughly read this document may operate this tool. Failure
to safely operate this tool may result in serious injury or death.
Inspect all jGun components as they are removed from the shipping container. If
damage is found to any component, contact your shipper immediately. Do not use
the tool.
Failure to follow correct tool usage could result in personal injury, co-worker
injury, and/or damaged tools and equipment.
Ensure your working area is clean and unobstructed before beginning work.
jGun maintenance and repair must be performed by a qualified pneumatic
technician.
Modifying a jGun or jGun accessory is dangerous and invalidates the warranty.
Inspect the tool before each use. Replace any obviously worn or damaged parts.
When not in use, store the jGun and jGun accessories in the plastic storage case
supplied with the tool. Do not expose the gun to high humidity or large
temperature variations.
Personal Protective Equipment
Always wear the appropriate personal protective equipment when operating a
jGun including gloves, safety goggles, hearing protection, hard hat, and safety
shoes
