Applying Torque
1. Insert an appropriate socket or drive attachment onto the square drive of the ratchet and onto
the fastener you want to tighten.
2. Apply hand pressure to the grip, and ONLY TO THE GRIP. You may support the wrench at the
ratchet head with the other hand to steady it, especially when using long socket extensions,
without appreciably affecting the accuracy of the wrench.
3. If, due to the required effort, you need to use both hands, put the other hand on the top of the
first hand, never on any other part of the wrench.
4. Apply slow and steady pull or push until the wrench momentarily releases, with or without a
distinct “click” sound. Release the pressure right at this point. DO NOT OVER TORQUE!
