Should a torque wrench be pulled towards you?
Always pull, DO NOT PUSH, to apply torque and adjust your stance to prevent a fall. A “cheater bar” should NEVER be used on a torque wrench to apply excess leverage. Do not use with sockets or fasteners showing wear or cracks. Make sure direction lever is fully engaged.
Can you damage a torque wrench to loosen bolts?
So long as users operate with caution and do not exceed the maximum torque, most torque wrenches can be used for undoing. By exceeding the maximum torque limit during a bolt loosening you can affect the wrench accuracy, causing problems for future use. If in any doubt, use another tool for loosening bolts.

Is my torque wrench accurate?
How do I know if my torque wrench is calibrated correctly? The only way to know if your wrench is accurate is to have it calibrated by a qualified calibration lab or do it yourself as was described above with a vise and weights. Proper calibration, however, requires certified weights.
How long do torque wrenches last?

Are torque wrenches reliable?
Accuracy. Mostly torque wrenches have an accuracy of (+/-) 5\%, which means a particular wrench should read within plus or minus 5\% of the exact torque value. For Example, we set the value 15 newton meters (nm) , it should click constantly when the actual torque is between 14.7nm – 15.5nm.
