Operation

Torque Settings

Select the desired torque setting before operating the screwdriver.

■

To increase the torque, turn the regulating handle clockwise.

■

To decrease the torque, turn the regulating handle counterclockwise.

When the selected torque is reached, the internal clutch disengages and a click is heard. This indicates

that the power to the motor is cut off.

Use a torque meter to check that the tool is set to the desired torque. The engraved marks on the ring are

just for reference.

Secure the regulating handle with a torque cover to prevent torque changes.

Do not use the screwdriver over the 80% of the rated maximum torque to avoid inaccurate clutch es-

cape.

during the whole tightening process.

The power adapter gives information about the tightening process:

If the tightening process is performed incorrectly, the power adapter will show a red light.

Do not change the running direction of the screwdriver while in operation, wait until the tool has
