This wrench will not prevent you from applying more
torque than set, it is not a torque limiting tool. The LCD
display will flash “STOP” if you exceed either the lower or
upper limit of intended use. At low settings the release is
gentle and there usually is no audible ‘click’ signal. Learn
how different amounts of torque ‘feel’, so you will reduce
the possibility of damage and/or injury due to accidental
over-torquing.
