To do so, press the button (d) on the lever selec-
tor (7) and turn the lever selector (7) so that the
arrow (a) coincides with the mark (c) on the

Important:
You only need to apply minimal pressure for hammer
drilling. Do not apply too much pressure as this will
put unnecessary strain on the motor. Check the
hammer drill at regular intervals.
Re-sharpen or replace bits whenever blunt.
