Essential Safety tips when using a hydraulic torque wrench

Hydraulic torque wrenches are “double acting” tools that fasten and loosen bolts. They operate through the force of a hydraulic flow that provides pressure to force the wrench in a rotary motion. After a few minutes of use, most people will find out that it is not difficult to operate a hydraulic torque wrench. However, operators should be cautious when using this high power device as it can be dangerous. Below we offer some advice on how to safely use a hydraulic torque wrench.

Give It A “Once Over”

Before Using the hydraulic torque wrench, examine it to ensure that all of its parts are firmly secure. Once the initial inspection is performed, the wrench will have to be exercised. Run it at full scale at least three times before starting the job. This allows the operator to ensure that the wrench's movable parts are moving in the right direction.


Be sure to operate the torque wrench within the manufacturer's advised calibration range. If the wrench is used at levels above those specified by the manufacturer, the operator will be in danger and the wrench itself might be harmed. Be sure to re-calibrate the wrench at consistent intervals. It is advisable to bring the wrench in to a calibration lab on an annual basis or after every four to five thousand cycles. Always re-calibrate the wrench if it falls or hits the ground with any force.

Dress Appropriately

Goggles-300[1] Always wear safety goggles when using a hydraulic torque wrench. Small particles will fly into the air that can harm the eyes. Be sure to tie up any long hair so that it is far away from the face. Loose or baggy clothing should be securely tucked into pants or held tightly to the body with a belt. Anything that extends from the body can easily get caught in the wrench. So wear tight fitting clothing and remove all jewellery before starting the job.

Socket Inspection

Always check the wrench's sockets to make sure that they are in a quality condition. Worn out or cracked sockets should never be used as they won't securely hold the wrench's nuts. If the sockets are large or small compared to the nuts, the wrench won't operate as it is designed. When using the wrench, keep a solid distance from the sockets for optimal safety. Don't forget that there is always the possibility that the sockets will break.

Hand Placement

Be sure to hold the wrench with a firm grip on the middle handle. A tight hold of the wrench is essential to the operator's personal safety and efficient operation. While hydraulic torque wrenches are constructed to be used without the turning of the hands, as is done with a conventional wrench, it should still be held tightly while it is operating. However, keep both hands far away from the wrench's reaction bar, also known as the boot. When the wrench is approaching its upper torque, continue operating it with a solid speed and don't push it.

Steady Capacity

Don't operate the wrench at its full capacity for every single job. Each job will have a unique wrench capacity. When in doubt, operate the wrench at medium capacity so that it can be held onto with ease. This will also ensure that the wrench has a long lifespan.
