3. Use and operation
3.1 Operation and instructions in use
3.1.1 Select the appropriate torque driver according to the torque range required when the fastener is tightened.
3.1.2 Set the torque value of the torque driver according to the torque required for tightening the fastener; turn the locking wheel in the opposite direction of \"LOCK\" to unlock (the scale lines of the main scale and auxiliary scale must be as shown in Figure 1 Only when the display is aligned, can it be turned and unlocked in the opposite direction of \"LOCK\". Loosen the adjustment ring, and adjust the position of the adjustment ring by hand or the attached hook wrench. The working torque value is the main scale indication + subscale indication . As shown in Figure 1, the torque value is: 2 + 0.1 = 2.1kg.cm. After completing the setting, turn the locking wheel to lock in the direction marked with \"\" LOCK \"\" (the scale lines of the main scale and sub-scale must be aligned as shown in Figure 1 before turning and locking in the direction of \"LOCK\") .
3.1.3 According to the form of the head of the fastener (cross, straight, plum, etc.), select the appropriate bit from the attachment and insert it into the hexagonal joint of the head of the torque driver.
3.1.4 Hold the handle and align the bit with the fastener, and turn the torque screwdriver until the tightening torque of the fastener reaches the set value. The torque screwdriver forwards the sound signal empty, accompanied by obvious hand vibration, prompting to complete the operation .
