Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in
connection with wood-treatment additives
(chromate, wood preservative). Materials
containing asbestos may only be worked by
specialists.
– Provide for good ventilation of the work-
ing place.
– It is recommended to wear a P2 filter-
class respirator.
Observe the relevant regulations in your
country for the materials to be worked.
Operation
Starting Operation
Setting the Operating Mode
With the selector switch for drilling/hammer
drilling
4
, the operating mode of the machine is
selected.
Note:
Change the operating mode only when the
machine is switched off! Otherwise, the ma-
chine can be damaged.
To change the operating mode, turn the selector
switch for “drilling/hammer drilling”
4
to the re-
quested position.
Reversing the Rotational Direction
(see figure D)
f
Actuate the rotational direction switch 8
only when the machine is at a standstill.
The rotational direction switch
8
is used to re-
verse the rotational direction of the machine.
However, this is not possible with the On/Off
switch
9
actuated.
Right Rotation:
For drilling and driving in
screws, push the rotational direction switch
8
left to the stop.
The indicator for right rotation
6
lights up
when the On/Off switch
9
is actuated
and the motor is running.
Left Rotation:
For loosening and unscrewing
screws and nuts, press the rotational direction
switch
8
through to the right stop.
The indicator for left rotation
7
lights up
when the On/Off switch
9
is actuated
and the motor is running.
Switching On and Off
To
start
the machine, press the On/Off switch
9
and keep it pressed.
To switch off the machine,
release
the On/Off
switch
9
.
For low temperatures, the power tool reaches
the full hammer/impact capacity only after a cer-
tain time.
Setting the Speed/Impact Rate
The speed/impact rate of the switched on pow-
er tool can be variably adjusted, depending on
how far the On/Off switch
9
is pressed.
Light pressure on the On/Off switch
9
results in
low speed/impact rate. Further pressure on the
switch increases the speed/impact rate.
Battery Charge-control Indication
The battery charge-control indicator
5
indicates
the charge condition of the battery for a few sec-
onds when the On/Off switch
9
is pressed
through halfway of fully.
Temperature Dependent Overload Protection
When using as intended for, the power tool can-
not be subject to overload. When the load is too
high or the allowable battery temperature of
70 °C is exceeded, the electronic control
switches off the power tool until the tempera-
ture is in the optimum temperature range again.
Additionally, the battery charge-control indica-
tor
5
flashes green and red at the same time un-
til the On/Off switch
9
is released.
