Mounting the Drill Chuck (see figure F)

The keyless chuck is mounted in reverse order.

f

Remove the steel pin from the drill hole on 
the spindle neck after mounting is complet-
ed.

The drill chuck must be tightened with a 
tightening torque of approx. 30 – 35 Nm.

Dust/Chip Extraction

f

Dusts from materials such as lead-containing 
coatings, some wood types, minerals and 
metal can be harmful to one’s health. Touch-
ing or breathing-in the dusts can cause aller-
gic reactions and/or lead to respiratory infec-
tions of the user or bystanders.
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

f

Observe correct mains voltage! The voltage 
of the power source must agree with the 
voltage specified on the nameplate of the 
machine. Power tools marked with 230 V 
can also be operated with 220 V.

Reversing the Rotational Direction 
(see figures G – H)

f

Actuate the rotational direction switch 3 
only when the machine is at a standstill.

The rotational direction switch 

3

 is used to re-

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

5

 actuated.

Right Rotation:

 For drilling and driving in 

screws, push the rotational direction switch 

3

upward on the left side and at the same time 
downward on the right side.

Left Rotation:

 For loosening and unscrewing 

screws and nuts, push the rotational direction 
switch 

3

 downward on the left side and at the 

same time upward on the right side.

Setting the Operating Mode

Drilling and Screwdriving

Set the selector switch 

2

 to the “Drill-

ing” symbol.

Impact Drilling

Set the selector switch

2

 to the “Im-

pact drilling” symbol.

The selector switch

2

 engages noticeably and 

can also be actuated with the machine running.

Switching On and Off

To 

start

 the machine, press the On/Off switch 

5

and keep it pressed.
To lock the 

pressed

 On/Off switch 

5

, press the 

lock-on button 

4

.

To 

switch off

 the machine, release the On/Off 

switch 

5

 or when it is locked with the lock-on 

button 

4

, briefly press the On/Off switch 

5

 and 

then release it.

Adjusting the Speed/Impact Frequency

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

5

 is pressed.

Light pressure on the On/Off switch 

5

 results in 

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

Preselecting the Speed/Impact Frequency

With the thumbwheel for speed preselection 

6

, 

the required speed/impact frequency can be 
preselected even during operation.
The required speed/impact frequency depends 
on the material and the working conditions, and 
can be determined through practical testing.
