• Grasp the tool holder 1 or the keyless replacement chuck
13 completely with your hand. Slide the tool holder 1 or
the keyless replacement chuck 13 with a turning motion
onto the drill chuck mounting until a distinct latching noice
is heard.
• The tool holder 1 or the quick change keyless chuck 13 is
automatically locked. Check the locking effect by pulling
the tool holder.
Changing the Tool
With the SDS-plus tool holder, simple and convenient tool
changing is possible without additional aids.
As a requirement of the system, the SDS-plus drilling 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.
The dust protection cap 2 largely prevents the entry of drilling
dust into the tool holder during operation. When inserting the
tool, take care that the dust protection cap 2 is not damaged.
 A damaged dust protection cap should be
changed immediately. We recommend having
this carried out by an after-sales service.
Inserting SDS-plus Drilling Tools
(see figure C)
• Clean and lightly grease the shank end of the tool.
• Insert the tool in a twisting manner into the tool holder until
it latches itself.
• Check the latching by pulling the tool.
Removing SDS-plus Drilling Tools
(see figure D)
• Push back the locking sleeve 3 and remove the tool.
Inserting Drilling Tools without SDS-plus
(see figure E)
Note: Do not use tools without SDS-plus for hammer drilling
or chiselling! Tools without SDS-plus and their drill chucks are
damaged by hammer drilling or chiselling.
• Insert the quick change keyless chuck 13.
• Firmly hold the retaining ring of the quick change keyless
chuck 13. Open the quick change keyless chuck by turn-
ing the front sleeve in the direction of the symbol
" ".
• Insert the drilling tool into the quick change keyless chuck
13. Firmly hold the retaining ring of the quick change key-
less chuck 13 and turn the front sleeve in the direction of
the symbol " ".
• Check the tight seating by pulling the tool.
Note: If the tool holder was opened to the stop, then the
latching noise possibly may be heard while closing the tool
holder and the tool holder will not close.
In this case, turn the front sleeve 14 once in the opposite direc-
tion of the arrow. Afterwards, the tool holder can be closed
(tightened) again.
• Turn the mode selector switch 5 to the "drilling" position.
Removing Drilling Tools without SDS-
plus (see figure E)
• Firmly hold the retaining ring of the quick change keyless
chuck 13. Open the quick change keyless chuck by turn-
ing the front sleeve in the direction of the symbol
" ".
• Remove the drilling tool.
Dust Extraction with the Extraction
Device (Accessory)
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 addi-
tives (chromate, wood preservative). Materials containing
asbestos may only be worked by specialists.
• As far as possible, use a dust extraction system suitable for
the material.
• 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 mate-
rials to be worked.
 Prevent dust accumulation at the workplace.
Dust can easily ignite.
Mounting the Extraction Device
(see figure F)
An extraction device (accessory) is required for dust extrac-
tion. When drilling, the extraction device retracts so that the
head of the extraction device is always positioned close to the
surface.
• Press the button for depth stop adjustment 9 and remove
the depth stop 11. Press button 9 again and insert the
extraction device from the front into the auxiliary handle
10.
• Connect a vacuum hose to the extraction sleeve 16 of the
extraction device.
