Starting Operation

Always set the rotational direction using the rotational direction switch (9) before starting the power tool:
The power tool will not start if the rotational direction switch (9) is in the centre (lock-off button).

  • Clockwise: To drive in screws, press the rotational direction switch (9) through as far as possible to the left.
  • Anti-clockwise: To loosen or unscrew screws, press the rotational direction switch (9) through as far as possible to the right.

The screwdrivers have a torque-dependent shut-off clutch that can be set to a value in the specified range. The clutch is triggered when the set torque is reached.

  • To switch on the power tool, press the on/off switch (8) down fully.
  • The power tool will switch off automatically when the set torque is reached.
  • If the on/off switch (8) is released too early, the preset torque will not be reached.

In the event of overload, the power tool switches off until it returns to the optimum operating temperature range. Release the on/off switch (8) and switch the power tool back on to continue working.

The power tool is not operated at optimum efficiency at rotational speeds lower than 50 %. This may cause the temperature dependent overload protection to be activated sooner. Set the output speed higher than 50 % or reduce the maximum torque used if you have problems with these settings.
