DIGITAL JGUN

The new digital jGun series from HYTORC is the world’s first torque-adjustable pneumatic multiplier with a digital readout and FRL-free operation. Unlike other systems that require a separate filter, regulator and lubrication system between the air line and the tool, the patented design of the digital jGun eliminates the need for this add-on for the highest level of portability and convenience.

01. DIGITAL READOUT

The digital jGun is the world’s first industrial torque multiplier with a digital readout for instant confirmation of selected torque. No more pressure-to-torque conversions or calculations. Select between ft-lbs and Nm.

02. BUILT-IN TORQUE ADJUSTMENT

The Digital jGun is the first of its kind with an onboard air regulator for simple torque adjustment with a twist of the connector at the bottom of the handle. Especially convenient when switching from tightening to loosening, giving you the ability to quickly adjust to full power for fast and easy break-out.

03. INDUSTRIAL-GRADE MOTOR

The new motor featured in the Digital jGun is a workhorse designed for heavy industrial use. With maximum power to weight and a rugged corrosion resistant design, this motor eliminates the need for separate air filters and lubrication systems making the Digital jGun the most portable air powered torque gun on the market.

Troubleshooting

Tool will not operate

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.
Gearbox is damaged and requires service.

Tool is leaking oil from exhaust port or handle face

Adjust FRL drip setting to 1 drip per every 15 seconds of operation.

Tool output is too low

Air leaking from coupler or rear cover gasket. Repair or replace fittings or gasket as necessary.
Air motor is worn and needs to be replaced.
Gearbox components may require service/lubrication.
Compressor cannot deliver 30 CFM @ 90 psi.
Plumbing does not meet the minimum requirements (1/2” – 3/4″ diameter hose and 3/8” fittings from compressor to tool).
FRL filter and/or silencer may be clogged.
Calibration date may be expired and tool requires current state calibration.

Tool output is too high

Application may be of “hard joint” nature and tool requires hard joint calibration.
Calibration date may be expired and tool requires current state calibration.

Trigger sticks

Remove trigger rod, clean and lubricate rod and guide bushing.

Tool runs slowly without pulling the trigger

Remove control valve, clean valve & seat. Replace valve if worn excessively.

Clutch will not fully engage in torque or rundown position (DSP tools)

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

Replace and install as necessary using permanent strength thread locker.

Excessive square drive damage/extraction

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)
