2. Depress the advance remote control button, causing the pressure to be shown on the
gauge.
3. Adjust the pressure by loosening the locking ring on the T Handle. Rotate the handle
clockwise to increase the pressure and counter clockwise to decrease the pressure.
When decreasing pressure, always lower the pressure below the desired point and then
bring the gauge back up to the desired pressure.
4. When the desired pressure is reached, retighten the locking ring, cycle the tool again to
confirm that the desired pressure setting has been obtained.
Tightening process
1. Having set your target pressure, cycle the wrench three or four times to full pressure
before putting it on the application. Cycling the tool ensures the system is operating
properly and removes trapped air, if any.
2. Place the correct size impact socket on the square drive and secure properly with a ring
and pin.
3. Place the tool and the socket on the nut, making sure that the socket has fully engaged
the nut. Further ensure that the drive retainer is engaged.
4. Make sure the reaction arm is firmly abutted against a stationary object (e.g. an adjacent
nut, flange, equipment housing etc.). When positioning the wrench, make sure that the
hose connections are well clear of any obstructions, and that all body parts are safely
out of harms way.
5. Apply momentary pressure to the system to ensure proper tool placement. If it doesn’t
look or act right, stop and readjust the reaction arm.
In use
1. By pushing down on the remote control button in the advance position, the rear of the
tool will be pushed back until the reaction arm makes contact with its reaction point.
2. Continue to hold down the button as the socket turns until the tool is fully extended and
will not turn the socket further. Successive cycles are made until the wrench stalls at the
preset torque.
3. The wrench will automatically reset itself and the operator will hear a series of clicks,
when the clicks finish the operator can again push the remote control button and the
socket will turn.
4. Continuing to hold down the remote control button will result in rapid build up of pressure
to the point of where the gauge reads what was preset prior to applying the wrench.
NOTE: The reading of full preset pressure after the cylinder is extended does not indicate that
this pressure (torque) is applied to the bolt. It only indicates that the cylinder is fully extended
and cannot turn the socket further until the wrench automatically resets itself.
