What should I pay attention to when using the preset torque wrench

Never use torque wrenches that exceed the reading. In order to keep the wrench in a good state of precision when used, the torque wrench used for the first time or not used for a long time needs to be used again, please be sure to operate 5-10 times with high torque value, so that its internal is fully lubricated. You can’t use a booster bar or something like that. Apply the force uniformly, keep the driving head. The sleeve and fastener are on the same plane, and make sure to apply the force in the direction of the middle of the handle of the vertical torque wrench.

If you need to use both hands at the same time to achieve a great torque, hold the handle with one hand and place the other hand on the first hand instead of the wrench. The use of torque wrench should stand smooth, to prevent imbalance fall. Never immerse the wrench or any part of the wrench in any liquid. Do not remove the torque wrench by yourself to avoid affecting the accuracy of the torque wrench. After using thetorque wrench, the torque value should be set to “0” to release the spring stress.

When using the preset wrench, please pay attention to safety. In addition to paying attention to your own safety and not falling down, please also pay attention to the safety of the wrench and try not to change its accuracy.
