# Starting Operation

Dusts, e. g. mineral dusts, can be harmful to health. Touching or breathing in this dust can trigger allergic reactions and/or cause respiratory illnesses in the user or in people in the near vicinity.
Materials containing asbestos may only be machined by specialists.

- Provide good ventilation at the workplace.
- It is advisable to wear a P2 filter class breathing mask.

The regulations on the material being machined that apply in the country of use must be observed.

To start the power tool, first slide the lock-off switch (5) upwards with your finger, then press and hold the on/off switch (6).

To switch off the power tool, release the on/off switch (6).

### Adjusting the Speed with the On/Off Switch

You can adjust the speed of the power tool when it is on by pressing in the on/off switch (6) to varying extents.

Slight pressure on the on/off switch (6) results in a low rotational speed. Increased pressure on the switch causes an increase in speed.

### Adjusting the Speed with the Speed Preselection Thumbwheel

The required speed can also be preselected with the thumbwheel (4) (even during operation).

The speed needed depends on the mixing material that is to be mixed and the work conditions.

##

The electronic soft start slowly increases the speed if the on/off switch (6) is pressed. This prevents the mixing material that is to be mixed from splashing.

##

The electronic system of the power tool keeps the mixer paddle speed constant in the set range across a wide load range. This guarantees a uniform performance.

##

The rapid shut-off function (KickBack Control) gives the user greater control over the power tool and offers them better protection than power tools that do not have KickBack Control. The power tool will switch off if it suddenly and unforeseeably rotates around the axis of rotation.

The rapid shut-off is indicated by the LED of the KickBack control (1) on the power tool flashing red.

To switch the tool back on, release the on/off switch and then press it again.

- It will no longer be possible to switch the power tool on if the KickBack Control function is faulty. Have the power tool serviced by a qualified repair person using only original replacement parts.
