Changing the Tool
With the SDS-plus tool holder, simple and con-
venient tool changing is possible without addi-
tional aids.
As a requirement of the system, the SDS-plus
drilling tool can move freely. This causes a cer-
tain radial run-out at no-load, which has no ef-
fect 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 hav-
ing 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 12.
Firmly hold the retaining ring of the quick
change keyless chuck 12. Open the quick
change keyless chuck by turning the front sleeve
in the direction of the symbol "
Insert the drilling tool into the quick change key-
less chuck 12. Firmly hold the retaining ring of
the quick change keyless chuck 12 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 13 once in the
opposite direction 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

Remove the drilling tool.
Dust Extraction with the Dust Extrac-
tion Attachment (Accessory)
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.
Mounting the Dust Extraction Attachment
(see figure F)
".
For dust extraction, the dust extraction attach-
ment (accessory) is required. When drilling, the
dust extraction attachment retracts so that the
attachment head is always close to the surface
at the drill hole.
