SQUARE DRIVE HYDRAULIC WRENCH OPERATING MANUAL
Instructions Before Use
1. Read and understand all instructions before operating the hydraulic wrench. Most malfunctions in new equip-
ment 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.
• Open all hydraulic controls several times to make
sure the system has been completely depressurized.
• If the system includes a gauge, double check the
gauge to make sure pressure has been released.• When making connections with quick disconnect
coupling, make sure the coupling are fully engaged. Threaded connections such as fittings, gauges, etc.,
must be securely tightened and leak-free.
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
they are secure and leak-free.
