retighten the bottom part of the auxiliary handle
16 by turning in clockwise direction.
Pay attention that the clamping band of the auxilia-
ry handle is positioned in the groove on the hous-
ing as intended for.
Selecting Drill Chucks and Tools
For hammer drilling and chiselling, SDS-plus tools
are required that are inserted in the SDS-plus drill
chuck.
For drilling without impact in wood, metal, ceramic
and plastic as well as for screwdriving and tapping,
use non-SDS-plus drilling tools (e. g., drill bits with
cylindrical shank). A keyless drill chuck is required
for such drilling tools.
Removing/Inserting the Quick Change
Chuck
The SDS-plus quick change chuck 2 can easily be
replaced against the quick change keyless chuck 1
provided.
Removing the Quick Change Chuck
(see figure C)
– Pull the lock ring for the quick change chuck 6
toward the rear, hold it in this position and pull
off the SDS-plus quick change chuck 2 or the
quick change keyless chuck 1 toward the front.
– After removing, protect the replacement chuck
against contamination.
Inserting the Quick Change Chuck (see figure D)
 Use only model-specific original equipment
and pay attention to the number of identifica-
tion grooves 23. Only quick-change chucks
with two or three identification grooves are
permitted. When an unsuitable quick-change
chuck is used, the application tool could fall out
during operation.
– Before inserting, clean the quick change chuck
and apply a light coat of grease to the shank
end.
– Grasp the SDS-plus quick change chuck 2 or the
quick change keyless chuck 1 completely with
your hand. Slide the quick change chuck with a
turning motion onto the drill chuck mounting 22
until a distinct latching noise is heard.
– The quick change chuck is automatically locked.
Check the locking effect by pulling the quick
change chuck.
Changing the Tool
The dust protection cap 4 largely prevents the en-
try of drilling dust into the tool holder during oper-
ation. When inserting the tool, take care that the
dust protection cap 4 is not damaged.

 A damaged dust protection cap should be
changed immediately. We recommend having
this carried out by an after-sales service.
Changing the Tool (SDS-plus)
Inserting SDS-plus Drilling Tools (see figure E)
The SDS-plus drill chuck allows for simple and con-
venient changing of drilling tools without the use of
additional tools.
– Insert the SDS-plus quick change chuck 2.
– 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.
As a requirement of the system, the SDS-plus drill-
ing tool can move freely. This causes a certain ra-
dial run-out at no-load, which has no effect on the
accuracy of the drill hole, as the drill bit centres it-
self upon drilling.
Removing SDS-plus Drilling Tools (see figure F)
– Push back the locking sleeve 5 and remove the
tool.
Changing the Tool (without SDS-plus)
Inserting (see figure G)
Note: Do not use tools without SDS-plus for ham-
mer drilling or chiselling! Tools without SDS-plus
and their drill chucks are damaged by hammer
drilling or chiselling.
– Insert the quick change keyless chuck 1.
– Firmly hold the retaining ring 25 of the quick
change chuck. Open the tool holder by turning
the front sleeve 24 until the tool can be inserted.
Tightly hold the retaining ring 25 and firmly turn
the front sleeve 24 in the direction of the arrow
until a distinct latching noise can be heard.
– 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 24 once in the op-
posite direction of the arrow. Afterwards, the tool
holder can be closed (tightened) again.
– Turn the mode selector switch 13 to the "drilling"
position.
Removing (see figure H)
– Firmly hold the retaining ring 25 of the quick
change chuck. Open the tool holder by turning
the front sleeve 24 in the direction of the arrow
until the tool can be removed.
