Selecting Drill Chucks and Tools
For hammer drilling, SDS-plus tools are required
that are inserted in the SDS-plus drill chuck.
For drilling without impact in wood, metal, ce-
ramic and plastic as well as for screwdriving,
tools without SDS-plus are used (e.g., drills
with cylindrical shank). For these tools, a key-
less chuck or a key type drill chuck are required.
Changing the Key Type Drill Chuck
To work with tools without SDS-plus (e.g., drills
with cylindrical shank), a suitable drill chuck
must be mounted (key type drill chuck or key-
less chuck, accessories).
Mounting the Key Type Drill Chuck
(see figure C)
Screw the SDS-plus adapter shank 14 into a key
type drill chuck 13. Secure the key type drill
chuck 13 with the securing screw 12. Please ob-
serve that the securing screw has a left-hand
thread.
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.
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 ef-
fect 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 20).
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" symbol.
Removing Drilling Tools without SDS-plus
Turn the sleeve of the key type drill chuck 13
with the drill chuck key in anticlockwise direc-
tion until the drilling tool can be removed.
Dust Extraction with the Dust Extraction
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.
