Warnings and Cautions: Safety First!

▲ WARNING

Never use a hydraulic torque wrench without a
hydraulic gauge to indicate the working pressure.

▲ WARNING

To avoid personal injuries and/or equipment damage,
be sure that all hydraulic components are rated for
10,000PSI (700bar) operating pressure.

▲ Warning

DO NOT exceed the allowable maximum torque of the
hydraulic torque wrench.

▲ WARNING

Immediately replace any worn or damaged parts with genuine Tors ion X replacement
parts.

▲ WARNING

To avoid personal injuries, equipment damage and/or warranty invalidation:
DO NOT Remove the shroud from the hydraulic torque wrench.
DO NOT Modify any component of the hydraulic torque wrench.
DO NOT Adjust the hydraulic torque wrench safety relief valve located inside the swivel
couplings.

▲ CAUTION

Keep all hydraulic torque wrench components away from excessive heat, flame, moving
machine parts, sharp edges and chemicals.

▲ CAUTION

Avoid sharp bends and kinks when routing the hydraulic hose assembly. A bent or kinked
hydraulic hose assembly will cause severe back-pressure. They will also damage the
internal lining of the hose leading to premature failure. Replace a kinked or damaged
hydraulic hose assembly immediately.

▲ CAUTION

DO NOT drive over, crush or drop heavy objects onto the hydraulic hose assembly. Crush
forces may damage hose wire strands and applying pressure to a damaged hose
assembly may cause it to rupture. Replace all crushed hydraulic hose assemblies
immediately.

▲ CAUTION

Do NOT expose the hydraulic hose assembly to high temperatures.

Other Safety Notes

• Loose or dirty couplers will cause tool not to operate properly.

• To avoid personal injuries and/or equipment damage, be sure that all hydraulic

components are rated for 10,000PSI (700bar) operating pressure.

• Always inspect the hydraulic hose assembly for damage and wear before using it.

• Make sure the hydraulic torque wrench swivel couplings, hose couplings and

hydraulic power pack couplings are clean and free of debris prior to connecting
the hydraulic torque wrench and hydraulic hose assembly to the assembled
power pack.

Proper Protective Equipment (PPE)

When operating hydraulic equipment, use proper safety equipment and clothing.
Consult with your company’s safety representative for this information.

Operation

Reference the Operation and Maintenance Manual of the electric hydraulic power pack
before beginning use.

Preparation

Prior to use determine:

• Nut or bolt head size

• Material and strength grade

• Determine the desired torque

Appendix I, presented for reference only, gives typical torque values specified for the
most commonly encountered fasteners. You should always abide by established
procedures for the job site. Torque sequence may vary from manufacturer to
manufacturer and even on job sites depending on the gasket material etc. Refer to your
company’s engineering department for this information.

Torque value

Determine the corresponding pressure of the hydraulic power pack to achieve the
required torque value.

You can find this information in the Pressure -Torque Conversion Chart provided with the
hydraulic torque wrench. You may also find this chart on the web @
