TorsionX® Low Profile Wrenches (Updated 1/27/15) 9
Operating the HexPro Series Low Profile Wrench
Before every operation, always read and follow the Operation Instructions.
Applying the Hydraulic Torque Wrench
1. Place the ratchet link on the nut.
2. Ensure it is the correct size and fully engaged.
3. Remove ratchet link from nut.
4. Attach the ratchet link to power head
5. Cycle the hydraulic torque wrench to engage the power
head with the ratchet link.
6. Place the torque wrench on the nut.
7. Position the reaction surface against an adjacent nut,
flange or solid system component.
8. Make certain that there is clearance for the hydraulic hose assembly, swivels and
couplings.
9. Do not allow the tool to react against the hydraulic hose assembly, swivels or
couplings.
10. Depress the remote control advance button to advance the piston rod.
11. If the piston rod end did not engage the drive pin in the ratchet link when the link
was joined to the power head, it will engage the pin automatically during the first
advance stroke.
12. Check to make sure all body parts are safely out of harm’s way before applying
pressure to the hydraulic wrench.
a. This tool has massive power and can cause physical harm.
13. The nut will begin to turn when you apply hydraulic pressure to the hydraulic
torque wrench and the reaction surface moves against the reaction point.
14. Once the piston reaches the end of its stroke, release the remote button and the
tool will automatically retract the piston.
15. The operator will hear an audible “click”.
a. Each “advance and retract” is considered on cycle.
16. Continue cycling the hydraulic torque wrench until it “stalls” and the preset
PSI/Torque has been attained.
17. Cycle the tool one last time to assure total torque.
Important:
The reading of full preset pressure after the cylinder is extended DOES NOT INDICATE
this pressure (torque) is applied to the bolt/nut. It only indicates that the cylinder is fully
extended and cannot turn the socket further until the tool automatically resets itself.
•Releasing the remote control button automatically retracts the cylinder.
•The hydraulic torque wrench will automatically reset itself.
•You will hear an audible “click” indicating that you can again push the remote
control button and the socket will turn.
