The position of the Low Profile Hydraulic Torque Wrench relative to the nut determines whether the action will be for Loosening or Tightening
of the nut. Refer figure 4 for Low Profile Hydraulic Torque Wrench Position for Tightening and Loosening application.
The power stroke of the Piston Assembly will always turn the Ratchet Hex toward the Shroud.
Refer Figure 4
1 Place the correct size of Ratchet Hex on the nut. Ratchet Hex will fully engages the nut.
2. Place the reaction surface against an adjacent nut, flange or solid system component. Keep clearance for the hoses, swivels,
inlets and End Plug. Avoid direct contact of the tool with hoses, swivels, inlets or end plug.
3. Switch on the Hydraulic Power Pack preset the pressure for the required torque, used the remote control button to advance
the Piston Assembly. At the beginning if the notch in the piston rod did not engage the Retract Pin in the Ratchet Link when the
Link was joined to the Housing, it will engage the Pin automatically during the first forward stroke.
4. When the Low Profile Hydraulic Torque Wrench is started, the reaction surface of the wrench will move against the contact point
and the nut will begin to rotate.
5. When the nut stop rotating and the Pump Gauge reaches the preset pressure, a sound “click” will be heard , the piston rod will
retract to the normal conditions after releasing the remote control button and the Hydraulic Torque Wrench will resets itself.
6. Continue to cycle the hydraulic torque wrench until it reaches to the position where the preset torque has been achieved preset
pressure of Hydraulic Power Pack.
7. Once the nut stops rotating, cycle the Hydraulic Torque Wrench one last time to achieve total torque.
