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.

2.4 LUBRICATION :
The frequency for the lubrication is dependent on operating conditions The Hydraulic Torque Wrench used in a clean enclosed
environment will require less servicing than a tool used open atmosphere and dropped in loose dirt or sand. Synthetic Grease is used
for lubrication. Whenever lubrication is required, lubricate as follows:
1. By removing Link Pin separate the Low Profile Cylinder from the Ratchet Link if they are joined.
2. After wiping of the old grease, apply Synthetic Grease to the hook notch in the Piston rod and make a thin layer of Synthetic Grease
onto the sides and faces of the two Sliders.
3. Disassemble the Ratchet Link as instructed in the Section 3 of the Maintenance and wash the components in a suitable cleaning
solution in a well-ventilated area.
4. Dry the components, then apply a film of Synthetic Grease onto the wear surface of both Side Plate Sleeves and the hubs of the
Ratchet.
5. Apply a light film of Synthetic Grease onto the inner faces of both Side Plates covering the area where the Drive Plate and
Drive Segment Pawl travel. DO NOT over grease the teeth of the Drive Segment or Ratchet. It can prevent the teeth from
engaging properly.
6. Reassemble the Ratchet Link as instructed in the Maintenance Section.

3.1.1 General Instructions
1. Do not disassemble the tool unless until required to replace or repair damaged parts.
2. Take precautionary measure while handling surfaces that will contain hydraulic oil under pressure.
1. Do not disassemble the tool unless until required to replace or repair damaged parts.
2. Take precautionary measure while handling surfaces that will contain hydraulic oil under pressure.
3. Hold a wrench in a leather–covered or copper–covered vise jaws to protect the surface of the part and help prevent distortion.
This is particularly for the threaded part and housings.
4. Do not remove any part that is a press fit in or on an assembly unless the removal of that part is necessary for repairs or replacement.
5. Do not disassemble the hydraulic cylinder assembly unless you are in a position of complete set of seals and O-rings for replacement.
6. Use only Standard size tools when disassembling these Hydraulic Torque Wrenches.
3.1.2 Steps for Disassembly of the Wrench
