auxiliary handle 17 to the required position. Then
tighten the wing bolt 11 again in clockwise direc-
tion.
Adjusting the Drilling Depth (see figure B)
The required drilling depth X can be set with the
depth stop 1.
Press the button for the depth stop adjustment 10
and insert the depth stop into the auxiliary handle
17.
The knurled surface of the depth stop 1 must face
downward.
Insert the SDS-plus drilling tool to the stop into the
SDS-plus tool holder 2. Otherwise, the movability of
the SDS-plus drilling tool can lead to incorrect ad-
justment of the drilling depth.
Pull out the depth stop until the distance between
the tip of the drill bit and the tip of the depth stop
corresponds with the desired drilling depth X.
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, ceramic
and plastic as well as for screwdriving, tools with-
out SDS-plus are used (e.g., drill bits with cylindri-
cal shank). For these tools, a keyless 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 keyless chuck,
accessories).
Mounting the Key Type Drill Chuck (see figure C)
Screw the SDS-plus adapter shank 20 into a key
type drill chuck 19. Secure the key type drill chuck
19 with the securing screw 18. Please observe
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 ap-
ply a light coat of grease.
Insert the key type drill chuck with the adapter
shank into the tool holder with a turning motion un-
til it automatically locks.
Check the locking effect by pulling the key type
drill chuck.
Removing the Key Type Drill Chuck
Push the locking sleeve 4 toward the rear and pull
out the key type drill chuck 19.

Changing the Tool
The dust protection cap 3 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 3 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 E)
The SDS-plus drill chuck allows for simple and con-
venient 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 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 4 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 19 (see "Changing the
Key Type Drill Chuck", page 37).
Open the key type drill chuck 19 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 19 and clamp the tool
uniformly.
Set the selector switch 9 to the "Drilling" symbol.
Removing Drilling Tools without SDS-plus
Turn the sleeve of the key type drill chuck 19 with
the drill chuck key in anticlockwise direction until
the drilling tool can be removed.
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. Touching or
breathing-in the dusts can cause allergic reac-
tions and/or lead to respiratory infections of the
user or bystanders.
Certain dusts, such as oak or beech dust, are
considered as carcinogenic, especially in con-
nection with wood-treatment additives (chro-
mate, wood preservative). Materials containing
asbestos may only be worked by specialists.
