Your hydraulic controlled torque wrench is one of the most precision instruments that is designed for tightening bolt heads on any excavator tracks, foundation connections, tower crane assemblies and many other applications.
Guidelines are always provided for their acceptable torque ranges for torque tools in the order by which specific bolts can be tightened to confirm application of torque.
It is necessary that you must follow the right maintenance and the best practice procedures as listed below:
- Always wear safety glasses/goggles when you are using any kind of hand operated tool.
- Always inspect equipment before the use to make sure that there are no cracked, worn areas on your equipment. Immediately replace if any weaknesses are found.
- Always follow the directions given by the manufacturer regarding: torque direction, torque pattern/sequence/force, use of lubrication or torque cycles.
- Always remain within the suggested working range provided for the torque wrench.
- Normally avoid dropping your torque wrench. If it gets dropped on any hard surface then its calibration may be affected. If the calibration goes out then the set torque reading seen on the wrench may not reflect actual value.
- Use your torque wrench during the process of final assembly. Avoid using it primarily for removing or installing all fasteners as any damage can be caused and may need recalibrating very soon.
- Apply any torque slowly and in proper manner. Any jerky movements may cause higher applied torque or lower than any desired and can damage your torque wrench.
- Set any click-type torque wrench at the manufacturer provided torque setting, while storing it. In case the settings are not specified, then set it to any lowest value.
- Torque wrenches are mostly length specific, and therefore always grasp your wrench in the center of its handle. If 2 hands are required then place one hand at the top of other.
- Never use a hammer with a wrench unless it has been exactly designed for such kind of purpose.
- As the wrench indicated with signals that any specific torque has reached, then stop pulling immediately.
- Torque wrench must be recalibrated when certain time or cycles have been completed as per the specification of the manufacturer.
- Avoid using cheater bars or any handle extensions unless it is advised by the manufacturer.
- Always store your torque wrenches in any clean and dry or protected area.
- Avoid etching, marking, or placing any labels on the torque wrenches.
