1.This torque wrench is a precision instrument intended to be used only to tighten screws, bolts and nuts to a desired torque.
2.Do not use it as a "nut breaker", pry bar, hammer, or in lieu of a regular ratchet wrench.
3.Do not apply torque in excess of the maximum capacity of the wrench. Apply load on the grip only, and do not use any handle extension bars (a piece of pipe put over the grip).
4. Make sure that you adjust the wrench to the exact torque units your specifications call for, or you will severely under-torque or over-torque, causing severe damage to the equipment you are working on.
5. Do not disassemble the wrench for any reason. Highly stressed internal components may cause severe injury when released in an unintended manner.
6. The wrench should be re-calibrated periodically. The calibration of the wrench should be checked at least once a year, after any abnormal handling or overloading, or after 5,000 cycles ("clicks").
1. Pull the lock knob out downside. The locking and unlocking directions are indicated by appropriate icons on the lock knob.
2. Turn the grip in the clockwise direction to increase the torque, and in the counterclockwise to decrease it.
3. The major scales show the amount of torque in both primary and secondary units. The minor scale shows fine increments in primary units. See examples on the next page.
4. Push the lock knob back to lock the grip. The minor scale may move a small amount to either side of the center line mark without affecting the accuracy of your setting.
