Operation and Maintenance Procedures

Use the HTL Low Profile Hydraulic Torque Wrench to install and remove large bolts that have minimal wrench clearance. This British made tool provides precision high torque during bolt makeup and maximum torque for bolt breakout.

The HTL Low Profile Torque Wrench is the ultimate torque wrench for flange work; it is lightweight, durable and amongst the safest controlled bolting solutions on the market. Hands-free operation, premium quality components and superior manufacturing make the HTL Low Profile Wrench the ideal choice for torqueing flanges. From design to manufacturing and calibration, the HTL Low Profile is a purpose built, second to none hydraulic torque wrench.

HTL’s Top Tips

• Never use hydraulic torque wrenches without a hydraulic gauge to indicate the working pressure.
• Avoid personal injuries and damage to equipment by ensuring all hydraulic components are rated for 10,000psi operating pressure.
• Do not exceed maximum torque of the hydraulic torque wrench.
• Immediately replace any worn or damaged parts.
• Do not adjust the hydraulic torque wrench safety relief valve located inside the swivel couplings.
• Keep all hydraulic torque wrench components away from excessive heat, sharp edges and chemicals.
• Avoid any kinks in the hose as this will cause severe back pressure, damaging the lining of the hose, leading to premature failure.
• Loose or dirty couplers will cause the tool not to operate properly.
• Always inspect the hydraulic hose for damage and wear before use.

Operation and set up

Before the use of any torque equipment, the following points should be determined:

• Nut or bolt head size
• Material and strength grade
• The desired torque

When setting up the torque wrench, the following four steps should be adhered to:

1. Inspect the components of the hydraulic torque wrench and its components. If all appears to be clean and damage free, the assembly process of the components can begin.
2. Connect the hydraulic torque wrench, the hydraulic hose assembly and the hydraulic power pack to a hydraulic circuit.
3. Ensure all the hydraulic connections are securely connected.
4. Check the hydraulic hose assembly is not kinked or damaged.

When loosening and tightening the nut position the tool relative to the nut to tighten or loosen the nut. The nut turns clockwise for tightening and anticlockwise for loosening.

When connecting the hydraulic hose assembly to the swivel, always ensure the connectors are fully engaged and screwed tightly together, ensuring that there are no gaps.

Periodically you should coat all moving parts with a good quality lubricant; under harsh environments, cleaning and lubrication should be performed more frequently.
