The electric wrench on the site is not enough torque. What's wrong with it?
If the range is enough, but the factory when the adjustment of small, contact agents, ask yourself how to adjust the set torque, if you can't adjust, back to factory tune.
Look at the range of your torque wrench and adjust the torque. Combined with actual operation torque.If the torque wrench itself is small, the maximum torque can not meet the requirements of the operation, buy a new one.
If the adjustment torque is sufficient, but the actual operation fails to achieve the set torque, then the agent detects the actual torque. Return to factory maintenance.
