Inserting the Key Type Drill Chuck
(see figure D)
Clean the shank end of the adapter shank and
apply a light coat of grease.
Insert the key type drill chuck with the adapter
shank into the tool holder with a turning motion
until it automatically locks.
Check the locking effect by pulling the key type
drill chuck.
Removing the Key Type Drill Chuck
Push the locking sleeve 3 toward the rear and
pull out the key type drill chuck 13.
Changing the Tool
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.
f 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 E)
The SDS-plus drill chuck allows for simple and
convenient changing of drilling tools without the
use of additional tools.
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
drilling tool can move freely. This causes a cer-
tain 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.
Removing SDS-plus Drilling Tools (see figure F)
Push back the locking sleeve 3 and remove the
tool.
Inserting Drilling Tools without SDS-plus
Note: Do not use tools without SDS-plus for ham-
mer drilling! Tools without SDS-plus and their
drill chucks are damaged by hammer drilling.
Insert a key type drill chuck 13 (see “Changing
the Key Type Drill Chuck”, page 19).
Open the key type drill chuck 13 by turning until
the tool can be inserted. Insert the tool.
Insert the chuck key into the corresponding holes
of the key type drill chuck 13 and clamp the tool
uniformly.
Set the selector switch 7 to the “Drilling” sym-
bol.
Removing Drilling Tools without SDS-plus
Turn the sleeve of the key type drill chuck 13 with
the drill chuck key in anticlockwise direction until
the drilling tool can be removed.
Dust Extraction with the Dust Extraction
Attachment (Accessory)
Mounting the Dust Extraction Attachment
(see figure G)
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.
Press the button for depth stop adjustment 8
and remove the depth stop 11. Press button 8
again and insert the dust extraction attachment
into the auxiliary handle 10 from the front.
Connect an extraction hose (diameter 19 mm,
accessory) to the extraction sleeve 15 of the dust
extraction attachment.
The vacuum cleaner must be suitable for the
material being worked.
When vacuuming dry dust that is especially detri-
mental to health or carcinogenic, use a special
vacuum cleaner.
