Reversing the rotational direction

The rotational direction switch 

8

 is used to reverse the rota-

tional direction of the machine. However, this is not possible 
with the On/Off switch 

10

 actuated.

Right rotation: 

Move the rotational direction switch 

8

 all the 

way to position 

.

Left rotation: 

Move the rotational direction switch 

8

 all the 

way to position 

.

Set the direction of rotation for hammer drilling, drilling and 
chiselling always to right rotation.

Switching On and Off

To save energy, only switch the power tool on when using it.

– To 

start

 the machine, press the On/Off switch 

10

.

When starting the machine for the first time, a starting delay 
is possible, as the electronic system of the power tool has to 
configure itself first.

– To 

switch off

 the machine, release the On/Off switch 

10

.

Setting the Speed/Impact Rate

The speed/impact rate of the switched on power tool can be 
variably adjusted, depending on how far the On/Off switch 

10

is pressed.

Light pressure on the On/Off switch 

10

 results in low 

speed/impact rate. Further pressure on the switch increases 
the speed/impact rate.

Electronic Precision Control (EPC) (see figure L)

EPC assists you when working with impact in sensitive mate-
rials by ensuring slow start-up and reduced operating speed.

– Slide the EPC switch 

30

 to the desired position.

Overload Clutch



If the tool insert becomes caught or jammed, the drive 
to the drill spindle is interrupted. Because of the forces 
that occur, always hold the power tool firmly with both 
hands and provide for a secure stance.



If the power tool jams, switch the machine off and loos-
en the tool insert. When switching the machine on with 
the drilling tool jammed, high reaction torques can oc-
cur.

Rapid Shut-off (Kickback Control)

The rapid shut-off feature (KickBack Control) provides better 
control over the power tool. The power tool will switch off if it 
suddenly and unforeseeably rotates around the drilling axis.

– To 

restart the machine

, release the On/Off switch and 

then actuate again.

Rapid shut-off is indicated by flashing of the worklight 

14

 on 

the power tool.



Rapid shut-off can trigger only when the power tool is 
running at maximum operating speed and can rotate 
freely around the drilling axis.

Temperature Control Indicator

The red LED of the temperature control indicator 

19

 signals 

that the battery or the electronics of the power tool (when the 
battery is inserted) are not within the optimum temperature 
range. In this case, the power tool will not operate at full ca-
pacity.

Temperature control of the battery:
– The  red  LED 

19

 lights up continuously after inserting the 

battery into the charger: The battery is not within the 
charging temperature range between 0 ° C and 45 ° C and 
cannot be charged.

– The  red  LED 

19

 flashes when you press the 

21

 button or 

the On/Off switch 

10

 (with battery inserted): The battery 

is outside of the permitted operating temperature range.

– For battery temperatures over 70 ° C, the power tool 

switches off until the battery is in the optimal temperature 
range again.

Temperature control of the power tool electronics:
– The  red  LED 

19

 lights up continuously when pressing the 

On/Off switch 

10

: The temperature of the machine’s elec-

tronics is below 5 ° C or above 75 ° C.

– At a temperature above 90 ° C , the electronics of the pow-

er tool switch off until the temperature is within the allow-
able temperature range again.

Working Advice

Adjusting the Drilling Depth (see figure M)

The required drilling depth 

X

 can be set with the depth stop 

17

.

– Press the button for the depth stop adjustment 

15

 and in-

sert the depth stop into the auxiliary handle 

16

.

Position for 

hammer drilling

 in concrete or 

stone

Position for 

drilling

 without impact in wood, 

metal, ceramic and plastic as well as for 
screwdriving

Vario-Lock

 position for adjustment of the 

chiselling position

The mode selector switch 

13

 does not latch in 

this position.

Position for 

chiselling

Position for maximum operating speed

Position for slow start-up and reduced operating 
speed
