The key is made of chrome-vanadium steel, which ensures its durability and strength. It has a mechanical dynamometric stretch, which after reaching the desired tightening force jumps with one clove, making a characteristic sound. The scale of moments is placed in the key handle, its adjustment occurs through its rotation. After setting the desired moment, block the key with protection at the end of the handle. The key has a GS certificate. Comparative statement of moments in various units of length and force: 1 kg*cm = 13.887 OZ*in (ounce X inch) 1 kg*cm = 0.867 LB*in (Punish X inch) 1 kg*m = 9,80665 n*m ( Niuton x meter) 1 kg*m = 7,233 lb*ft (pound x foot) 1 ft*lb = 12 lb*in (pound x inch) 1 dm*n = 14.16 oz*in (ounce x inch) is used Mainly in automotive technique for precise fastening and wherever the manufacturer determined the required time of tightening the connector. - Choose the appropriate NM or In-LBS scale. Unlock the micrometer knob. - Place the micrometer knob so that "0" on the scale of the knob covers with a vertical line on the key's shoulder. - rotate the micrometer knob according to the direction of the clockwise movement until the requested torque is set. - The desired torque is set when the scale on the micrometer knob will cover with the vertical line on the key's shoulder. - Then block the micrometer knob and set the appropriate direction of rotation of the ratchet, after that the key is ready for use. - Appropriate attachment should be applied to the key. When tightening, reaching the set moment is signaled by clicking the key. If you hear or feel the click, stop tightening. - dynamometric key - factory calibration certificate (individual for each key, marked with the serial number of the key) - user manual - warranty card - suitcase
