SQUARE DRIVE HYDRAULIC WRENCH OPERATING MANUAL
Instructions Before Use
1. Read and understand all instructions before operating the hydraulic wrench. Most malfunctions in new equipment are the result of improper operation and/or setup. It is the operators responsibility to read, understand, and
follow all safety instructions.
2. Remove the hydraulic wrench from the shipping container and visually inspect all components for any shipping
damage. If any damage is found, notify the carrier immediately. DO NOT USE TOOL.
3. Locate a solid, secure reaction point to absorb and counteract the forces created as the hydraulic wrench is
operated.
4. Make sure the hydraulic hoses are free of the reaction point.
5. Momentarily pressurize the system. If the wrench tends to “ride up” or “creep”, stop and readjust the reaction
arm to a more solid and secure reaction point.
6. Cycle the hydraulic cylinder inside the wrench to ensure proper function.
Note: Each time the hydraulic cylinder inside the wrench is extended
and retracted, it is called a cycle.
Working Pressure
The maximum working pressure for this hydraulic wrench is 10,000 psi (68,900 kPa). Make sure all hydraulic
equipment used with this wrench are rated for 10,000 psi (68,900 kPa) operating pressure.
Hydraulic Connections
• Never connect or disconnect any hydraulic hoses or
fittings without first unloading the wrench and the
pump.
WARNING

must be securely tightened and leak-free.
IMPORTANT
they are secure and leak-free.
• Open all hydraulic controls several times to make
sure the system has been completely depressurized.
• If the system includes a gauge, double check the
Threaded connections such as fittings, gauges, etc.,
Loose or improperly threaded fittings can be potentially dangerous if pressurized, however,
over-tightening can cause premature thread failure. Fittings should only be tightened until

hydraulic equipment.
• Always wear hearing protection as required.
• Operation, repair, or maintenance of hydraulic
equipment should be performed by a qualified
person who understands the proper function of
hydraulic equipment per local directives and
standards.
• To prevent personal injury, use common sense. Do
not use any power equipment under the influence of
any mood altering substances.
• Never place your hands or other body parts near
a hydraulic fluid leak.
Never use your hands or other body parts to check
for a possible leak.
High pressure fluid can be injected under your skin
causing serious injury and/or infection.
• Electric motors may spark, causing an explosion
when flammable materials are present. Do not
operate in an explosive atmosphere or in the presence of conductive liquids. Use an air motor or
hand pump instead.

Safety
A) Never exceed the torque wrench maximum working pressure (Advance 689 Bar / 10,000 psi, Retract 69
Bar / 1000 psi)
B) Keep hands and fingers clear of the torque wrench head and reaction arm area, before and during operation.
Fingers could be inadvertently trapped if care is not taken.
C) Keep other personnel clear of the working area and only allow trained personnel to use the equipment. Ideally
rope off the working area.
Prior to operation, ensure that all hoses, sockets and ancillary equipment is undamaged and fit for purpose.
D)
Ensure that all torque wrench components (i.e. square drive, reaction arm, etc.) are properly attached and
secure. Ensure that the square drive retainer button is properly located.
E) Do not strike any of the components, including the socket, with a hammer in order to shock the nut free.
F) Check that reaction structures are strong and rigid enough to accept the torque tool reaction forces. Do not use
wedges, packing pieces, etc as a temporary reaction.
G) Take care when handling equipment. Quick connect couplings are especially susceptible to knocks and damage
and therefore care must be taken. Note that damaged couplings are difficult to connect. Do not force couplings.
H) Do not retighten any equipment whilst under pressure.
) Some torque wrenches (and sockets) weigh in excess of 20Kg, therefore

Operating Instructions
J) Do not strike, misuse or abuse any of the equipment. If any abuse or misuse of the equipment is evident, the
warranty shall be invalid and the Manufacturer shall not be responsible for any injuries or failures as a result.
) In some instances it may be necessary for the Operator to support the torque wrench whilst it is tightening, i.e.

upside down applications. If the torque tool cannot be strapped into position using ropes, etc, then the operator
ust take the utmost care to avoid pinch points.

L) Never use the torque wrench with just one hose connected to the Advance port (port ‘A’). This will cause a pres-
sure intensification within the retract chamber possibly leading to tool damage. Always ensure that both hoses
are connected.
OPERATION
For top performance, frequently inspect wrench, pump, and accessories for visual damage
CAUTION
General
Each hydraulic wrench is supplied completely assembled and ready for use. A hydraulic pump is required to provide the speed and pressure that makes the hydraulic wrench system efficient and accurate.
Always follow instructions for proper wrench and pump maintenance.
Do not use other equipment to increase the capability (for example, hammering on socket wrench).
Connecting the System
The hydraulic wrench head and power pack are connected by a 10,000 psi (68,900 kPa) single-line hose assembly.
Each end of the hose will have one female connector.
NOTE: DO NOT switch the hose connector from female to male. It is necessary for the hose to have a female connector to
engage the male connecter on the hydraulic wrench.
Electrical Connections
Make sure the power supply is compatible with the requirements of the electric pump motor. Minimize the length of
extension cords and be sure they are of adequate gauge and grounded.
Air Connections
Make sure the air flow rating is adequate and compatible prior to pressuring the pump. Make sure all connections
are tight and leak-free
Changing the Drive Direction
In order to change drive direction, press and hold the drive release button, then pull out the square drive. The
square drive, retainer cap and button assembly are now free from the torque wrench, take care not to lose them
To re-install, insert the square drive into the tool head (the square drive won’t enter until the splines are aligned)
and replace the retainer cap assembly.
As a check, pull the square drive to ensure that it is locked in position.
Using the Reaction Arm

multitude of positions, always try to use the torque tool with the reaction arm positioned parallel to the socket (i.e.
90° to the torque tool body). See Fig. 2 below
