Inserting the Battery
Before re-inserting the battery 10 remove the
protective cap 14 if necessary (see figure ).
Set the rotational direction switch 6 to the centre
position (locked off). Slide the charged battery 10
into the handle until it can be felt to latch.
Switching On and Off
To start the machine, press the On/Off switch 7
and keep it depressed.
The machine runs with variable
speed between 0 and maximum,
depending on the pressure applied
to the On/Off switch 7. Light pres-
sure on the On/Off switch 7 results
in low rotational speed, thus allow-
ing drilling to begin in a smooth,
controlled manner. Further pres-
sure on the switch results in an in-
crease in speed.
To switch off the machine, release the On/Off
switch 7.
Do not strain the machine so heavily that it comes
to a standstill.
The machine is not suitable for stationary op-
eration, e. g., in a drill stand.
Overload Clutch
If the drill bit jams or edges, the drive to the
drill spindle is interrupted.
Due to the arising forces always hold the ma-
chine firmly with both hands and provide for
a secure stance.
Before pulling out a stuck tool insert, first remove
the machine from it.
Reversing the Rotational Direction
Operate the rotational direction switch 6
only at a standstill.
The rotational direction switch 6 is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch 7 actuated.
Right Rotation
Turn the rotational direc-
tion switch through to
the left stop (normal op-
eration: drilling, screw-
driving, etc.).
Left Rotation
Press the rotational di-
rection switch through to
the right stop (for loos-
ening and unscrewing
screws and nuts).
Set the impact stop switch 5 to “Drilling”
(only at a standstill).
Set the impact stop switch 5 to the desired posi-
tion:
Drilling
Hammer drilling
When releasing the On/Off switch 7 the speed of
the drill chuck is reduced to a stop, thus prevent-
ing the run-on of the tool.
Any sparking occurring during this process in the
area of the upper ventilation slots is normal and
does not damage the machine.
For screwdriving applications, wait until the screw
is flush with the material and then release the
On/Off switch 7. The screw head does not pene-
trate into the material then.
