– Pull out the depth stop until the distance between the tip of
the drill bit and the tip of the depth stop correspond with
the desired drilling depth X.
Selecting Drill Chucks and Tools
For hammer drilling, SDS-plus tools are required that are in-
serted in the SDS-plus drill chuck.
For drilling without impact in wood, metal, ceramic and plas-
tic as well as for screwdriving, tools without SDS-plus are
used (e.g., drills with cylindrical 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 cylindri-
cal 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 se-
curing 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 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 4 toward the rear and pull out the
key type drill chuck 19.
Changing the Tool
The dust protection cap 3 largely prevents the entry of drilling
dust into the tool holder during operation. When inserting the
tool, take care that the dust protection cap 3 is not damaged.
 A damaged dust protection cap should be changed im-
mediately. 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 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 certain 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 4 and remove the tool.
Inserting Drilling Tools without SDS-plus
Note: Do not use tools without SDS-plus for hammer 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 17).
– 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 Extraction Attach-
ment (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 reactions 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 connection with wood-treat-
ment additives (chromate, wood preservative). Materials
containing asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suita-
ble for the material.
– Provide for good ventilation of the working place.
– It is recommended to wear a P2 filter-class respirator.
Observe the relevant regulations in your country for the
materials to be worked.
 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Mounting the Dust Extraction Attachment (see figure G)
For dust extraction, the dust extraction attachment (accesso-
ry) 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 10 and remove
the depth stop 1. Press button 10 again and insert the dust
extraction attachment into the auxiliary handle 17 from the
front.
– Connect an extraction hose (diameter 19 mm, accessory)
to the extraction sleeve 21 of the dust extraction attach-
ment.
The vacuum cleaner must be suitable for the material being
worked.
When vacuuming dry dust that is especially detrimental to
health or carcinogenic, use a special vacuum cleaner.
Adjusting the Drilling Depth on the Dust Extraction At-
tachment (see figure H)
The required drilling depth X can also be adjusted when the
dust extraction attachment is mounted.
