How to use?
1.Pull the lock knob down and hold it. The wrench is unlocked.
2.Turn the handle to set the torque while holding the lock knob. Clockwise increase value, counterclockwise decrease value.
3.After setting the required torque, release the hand, and the button will bounce back and lock the handle.
4.Turn the handle left and right to make sure the wrench is locked and start using. (The minor scale may move a small amount to either side of the centerline mark without affecting the accuracy of your setting.)
5.Rotate the wrench clockwise, when you hear the"click", it means that you have reached the required strength.
6.After use, reset the torque wrench to 0 to maintain its life.
