01. 3-IN-1 BOLTING SYSTEM

The jGun Dual Speed is the only pneumatic multiplier that gives you the flexibility to use it for rundown, final torque and heavy duty breakout. A simple twist of the collar switches the tool from high speed rundown mode into the max power mode with adjustable torque so you can choose the right output for your job.

02. INTUITIVE DESIGN

This robust tool eliminates the need for multiple systems making training simpler and reducing the chance for operator error. When multiple systems are used to assemble a bolted joint there is more chance for operator error. The jGun Dual Speed makes the job simpler by giving operators one easy to use system that can be used from start to finish.

03. WHEEL GUN ACCESSORY

The wheel gun accessory is the obvious choice for wheel bolting and all nuts and bolts in confined spaces. The powerful extension system delivers the desired torque without compromise to power or durability. With industry-leading repeatability and intuitive design, job integrity is always assured.

Troubleshooting Open or Close
Tool will not operate
1. Air motor is seized and needs to be replaced. Confirm recommended FRL lubricator drip (1 drip per every 15 seconds). Make sure air supply is dry.
2. Gearbox is damaged and requires service.
Tool is leaking oil from exhaust port or handle face
1. Adjust FRL drip setting to 1 drip per every 15 seconds of operation.
Tool output is too low
1. Air leaking from coupler or rear cover gasket. Repair or replace fittings or gasket as necessary.
2. Air motor is worn and needs to be replaced.
3. Gearbox components may require service/lubrication.
4. Compressor cannot deliver 30 CFM @ 90 psi.
5. Plumbing does not meet the minimum requirements (1/2” – 3/4" diameter hose and 3/8” fittings (from compressor to tool).
6. FRL filter and/or silencer may be clogged.
7. Calibration date may be expired and tool requires current state calibration.
Tool output is too high
1. Application may be of “hard joint” nature and tool requires hard joint calibration.
2. Calibration date may be expired and tool requires current state calibration.
Trigger sticks
1. Remove trigger rod, clean and lubricate rod and guide bushing.
Tool runs slowly without pulling the trigger
1. Remove control valve, clean valve & seat. Replace valve if worn excessively.
Clutch will not fully engage in torque or rundown position (DSP tools)
1. Move shifter ring back towards its original position and tap the trigger (while tool is connected to an air supply). This will change the input shaft orientation and will now allow the ring to fully engage in the opposite direction.
Loose gearbox housing screws
1. Replace and install as necessary using permanent strength thread locker.
Excessive square drive damage/extraction
1. Poor reaction point. Make sure reaction point is down near the bottom or “flat” section of the reaction arm paddle. If your reaction arm does not fit your application use a more appropriately configured reaction fixture.
Impact function is weak (ZGUN and Thrill Gun)
1. For best results make sure FRL setting are at 90 psi (min) when using the rundown/impact function.
