Adjusting the speed

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

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.
