Adjusting the speed

Select the correct rotational speed before starting work. The rotational speed must be appropriate for both the drilling diameter and the material you intend to drilled. If an incorrect rotational speed is selected, the application tool may become jammed in the workpiece.

Use the speed diagram (6) to help you set the appropriate rotational speed. It shows the speed that should be set (rpm) depending on the drill diameter (dia. in mm) for the materials Steel and Aluminium.

Mechanical gear selection

Only operate the gear selector switch (21) when the power tool is not in use.

You can preselect 2 speed ranges with the gear selector switch (21).

Gear 1:
Low speed range; for working with large drilling diameters.

Gear 2:
High speed range; for working with small drilling diameters.

Turn the gear selector switch (21) to the required position.

If the gear selector switch (21) cannot be turned all the way, turn the drill chuck slightly with the drill.

Electronic speed control

The speed regulator (15) enables continuously variable adjustment of the speed of the power tool.

To switch on the power tool, turn the on/off switch (13) to position .
Press the button (33) to switch the indicator area of the display to "Speed".
Turn the speed regulator (15) until the required speed is shown on the display (14).
