hexagonal shank application tool or the keyless chuck with
application tools that do not have SDS quick.
For screwdriving, only use screwdriver bits which have a ball
catch (14) (DIN 3126-E6.3). Other screwdriver bits (13)
can be inserted using a universal bit holder with ball catch
(12).
You will find a selection of suitable application tools in the
accessories overview at the end of these operating instruc-
tions.
Changing the drill chuck
Changing the Keyless Chuck
You must use the keyless chuck (20) to work with applica-
tion tools that do not have SDS-Quick (e.g. cylindrical shank
drill bits).
Inserting the keyless chuck (see figure B)
– Clean and lightly grease the insertion end of the shank.
– Insert the keyless chuck (20) with the shank into the tool
holder while turning it until it locks automatically.
– Check that it is locked by pulling the keyless chuck.
Removing the Keyless Chuck
– Push the locking sleeve (3) back and remove the keyless
chuck (20).
Changing the Tool
The dust protection cap (2) largely prevents the penetration
of drilling dust into the tool holder during operation. When
inserting the tool, make sure that the dust protection cap (2)
does not become damaged.
Replace a damaged dust protection cap immediately.
u
It is recommended that you have use an after-sales
service for this.
Changing the Tool
The tool holder can also accommodate dif-
ferent application tools with a hexagonal
shank with groove and SDS quick shank.
The tool holder allows for simple and con-
venient tool-free changing of the application
tool.
As a requirement of the system, the application tool can
move freely. This causes a certain radial run-out at no-load,
which has no effect on the accuracy of the drill hole, as the
drill bit centres itself upon drilling.
Inserting SDS-Quick application tools (see figure C)
– Clean and lightly grease the insertion end of the applica-
tion tool.
– Insert the application tool into the tool holder while turn-
ing it until it locks automatically.
– Check the latching by pulling the tool.
Removing SDS-Quick application tools (see figure D)
– Push the locking sleeve (3) back and remove the applica-
tion tool.

Inserting application tools that do not have SDS quick
(see figure E)
Note: Application tools that do not have SDS-Quick must not
be used for hammer drilling. Hammer drilling will damage
tools without SDS-Quick along with their chucks.
– Insert the keyless chuck (20).
– Hold the rear sleeve (22) of the keyless chuck (20) firmly
and turn the front sleeve (21) anti-clockwise until the tool
can be inserted. Insert the tool.
– Hold the rear sleeve of the keyless chuck (20) and firmly
tighten the front sleeve by hand in a clockwise direction
until it stops clicking. This will automatically lock the drill
chuck.
– Check that it is seated securely by pulling the tool.
Note: If the tool holder was unscrewed all the way, a scrap-
ing sound may be heard while retightening the tool holder
and it may not fully tighten.
In this case, turn the front sleeve (21) anti-clockwise by one
turn. This will allow the tool holder to be fully tightened.
– Turn the impact/mode selector switch (4) to the "drilling"
position.
Removing application tools that do not have SDS-Quick
(see figure F)
Hold the rear sleeve (22) of the keyless chuck firmly and
turn the front sleeve (21) of the keyless chuck anti-clock-
wise until the application tool can be removed.
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.
