Changing the tool
Wear protective gloves when changing tools. The drill
u
chuck may heat up significantly when it is used for long
periods.
Keyless chuck (see figure B)
The drill spindle is locked when the on/off switch (6) is not
pressed. This makes it possible to change the application
tool in the drill chuck quickly, conveniently and easily.
Open the keyless chuck (1) by turning it in the direction of
rotation ➊ until the tool can be inserted. Insert the tool.
Firmly tighten the sleeve of the keyless chuck (1) by turning
it by hand in the rotational direction ➋ until it stops clicking.
This will automatically lock the drill chuck.
The lock will disengage again if you turn the sleeve in the op-
posite direction to remove the tool.
Keyed chuck (see figure C)
Open the keyed chuck (12) by turning it until the tool can be
inserted. Insert the tool.
Insert the chuck key (11) into the corresponding holes of the
keyed chuck (12) and clamp the tool evenly.
Screwdriving tools (see figure D)
You should always use a universal bit holder (14) when using
screwdriver bits (13). Only use screwdriver bits that fit the
screw head.
For screwdriving, make sure the "drilling/impact drilling" se-
lector switch (2) is always set to the "drilling" symbol.
Changing the drill chuck
Pull the plug out of the socket before carrying out any
u
work on the power tool.
Removing the drill chuck (see figure E)
Remove the auxiliary handle (8) and set the gear selector
switch (7) to the middle position between first and second
gear.
Insert a steel pin with a diameter of 4 mm and a length of ap-
prox. 50 mm into the hole on the spindle collar to lock the
drill spindle in place. Clamp a hex key (15) in the keyless
chuck (1), leading with the short shaft.
Place the power tool on a firm surface, e.g. a work bench.
Hold the power tool in place and loosen the keyless chuck
(1) by turning the hex key (15) in the rotational direction ➊.
A tightly seated keyless chuck is loosened with a light blow
on the long shaft of the hex key (15). Remove the hex key
from the keyless chuck and completely unscrew the keyless
chuck from the power tool.
Fitting the Drill Chuck (see figure F)
To fit the keyless chuck/keyed chuck, perform the same
steps in reverse order.
The drill chuck must be tightened using a tight-
ening torque of approx. 50–55 Nm.
After successfully fitting the drill chuck, remove the
u
steel pin from the hole again.

Dust/Chip Extraction
Dust from materials such as lead-containing coatings, some
wood types, minerals and metal can be harmful to one's
health. Touching or breathing-in the dust can cause allergic
reactions and/or lead to respiratory infections of the user or
bystanders.
Certain dust, such as oak or beech dust, is considered carci-
nogenic, especially in connection with wood-treatment ad-
ditives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the ma-
terials to be worked.
Avoid dust accumulation at the workplace. Dust can
u
easily ignite.

u
power source must match the voltage specified on the
rating plate of the power tool.Power tools marked
with 230 V can also be operated with 220 V.

u
ual current device (RCD) with a nominal residual current
of 30 mA or less.
Setting the rotational direction (see figure G)
Only operate the rotational direction switch (3) when
u
the power tool is not in use.
The rotational direction switch (3) is used to change the ro-
