4. Setup

The TEKTON torque wrench is shipped pre-calibrated and ready for immediate use. Before first use, familiarize yourself with the torque setting mechanism.

Setting the Torque Value:

  1. Locate the spring-loaded adjustment collar on the handle.
  2. Pull down the adjustment collar to unlock it.
  3. Rotate the handle to align the desired torque value (in.-lb. or Nm) with the main scale. The main scale shows major increments (e.g., 10, 20, 30 in.-lb.).
  4. Use the micro-scale on the rotating handle for fine adjustments. Each full rotation of the micro-scale typically represents a major increment on the main scale.
  5. Once the desired torque is set, release the adjustment collar. It will automatically lock into place, securing your setting.
