The purpose of safety rules is to attract your attention to
possible dangers. The safety symbols and the explanations
with them, require your careful attention and understanding.
The safety warnings do not by themselves eliminate any
danger. The instruction or warnings they give are not
substitutes for proper accident prevention measures.

for smooth drilling.
To deactivate the hammer action, turn the lever switch (6)

To reactivate the hammer action, the lever switch (6) has to
be reset to poisition (a).
Only after the on/off switch (2) is actuated and the machine
starts does the gear box shift to the selected mode.
Note: Left rotation when impact drilling damages the drill.
Switch off the impact mechanism for diamond crown drilling
or for mixing work.
