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.
