4.1 Attaching Sockets and Extension

1. Select the appropriate socket (17mm, 19mm, or 21mm) or the 125mm extension bar for your task.
2. Firmly push the chosen accessory onto the 1/2-inch square drive of the torque wrench until it clicks into place.

4.2 Моменттин маанисин орнотуу

The torque wrench features a dual-range scale for precise adjustment.

1. Кулпуну ачуу: Rotate the locking knob at the end of the handle counter-clockwise to unlock the adjustment mechanism.
2. Тууралоо: Rotate the handle to set the desired torque value. The main scale on the body provides major increments (e.g., 28, 42, 56 Nm), while the smaller scale on the handle allows for fine adjustments (0-12 Nm). Add the value from the handle scale to the main scale value to get the precise setting. For example, to set 100 Nm, align the 98 Nm mark on the main scale with the edge of the handle, then rotate the handle until the '2' mark on the handle aligns with the center line, resulting in 98 + 2 = 100 Nm.
3. Кулпу: Once the desired torque is set, rotate the locking knob clockwise to secure the setting.

Сүрөт 4.2: Illustration of the torque adjustment process: Unlock the handle, rotate to adjust the desired torque value, and then lock the handle to secure the setting.

5.1 Моментти колдонуу

1. Ensure the torque wrench is set to the correct torque value and locked.
2. Розетканы бекиткичке бекем орнотуңуз.
3. Hold the torque wrench by the handle and apply steady, increasing pressure in the tightening direction (clockwise for most fasteners).
4. Continue applying pressure until you feel and hear a distinct "click" from the wrench. This indicates that the preset torque has been reached.
5. Immediately stop applying force once the click is felt/heard. Do not continue to tighten the fastener beyond this point.
6. Remove the torque wrench from the fastener.

Сүрөт 5.1: Examples of the torque wrench in use for various applications, including tightening wheel nuts, general auto repair, industrial tasks, and motorcycle maintenance.

5.2 Ratchet Head Direction

The ratchet head allows for both clockwise (CW) and counter-clockwise (CCW) operation. Use the switch on the ratchet head to select the desired direction for tightening or loosening. For torque application, ensure the switch is set to the tightening direction (usually clockwise).
