Operating the Wrench
The 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 that the system is operating properly and removes
trapped air, if any.
2. Place the proper 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 harm’s way.
5. THEN, AND ONLY THEN, 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 you hear a click which will signify the
hydraulic cylinder inside the tool is fully extended and will not turn the socket further.
3. Continuing to hold down the remote control button will result in a rapid build up of pressure to the
point of where the gauge reads what was preset prior to applying the wrench.
IMPORTANT:
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.
Releasing the remote control button will retract the cylinder. The wrench will automatically reset itself and
the operator will hear a click indicating they can again push the remote control button and the socket will
turn. Each time the cylinder is extended and retracted, it is called a cycle. Successive cycles are made
until the wrench stalls at the preset torque.
