For drilling without impact in wood, metal, ceramic and plas-
tic as well as for screwdriving, tools without SDS-plus are
used (e.g., drill bits with cylindrical shank). For these tools, a
keyless chuck or a key type drill chuck are required.
Changing the Keyless 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).
Inserting the Keyless Chuck (see figure C)
– Clean the shank end of the adapter shank and apply a light
coat of grease.
– Insert the keyless chuck 18 with the adapter shank into the
tool holder with a turning motion until it automatically
locks.
– Check the locking effect by pulling the keyless chuck.
Removing the Keyless Chuck
– Push the locking sleeve 4 toward the rear and pull out the
keyless chuck 18.
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 D)
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 E)
– Push back the locking sleeve 4 and remove the tool.
Inserting Drilling Tools without SDS-plus (see figure F)
Note: Do not use tools without SDS-plus for hammer drilling
or chiselling! Tools without SDS-plus and their drill chucks are
damaged by hammer drilling or chiselling.
– Insert the keyless chuck 18.
– Hold the rear sleeve 20 of the keyless chuck 18 and turn
the front sleeve 19 in anticlockwise direction until until the
tool can be inserted. Insert the tool.
– Tightly hold the rear sleeve of the keyless chuck 18 and
firmly turn the front sleeve clockwise by hand until the
locking action is no longer heard. This automatically locks
the drill chuck.
– Check the tight seating by pulling the tool.
Note: If the tool holder was opened to the stop, then a latch-
ing noise possibly may be heard while closing the tool holder
and the tool holder will not close.

In this case, turn the front sleeve 19 once in anticlockwise di-
rection. Afterwards, the tool holder can be closed (tight-
ened).
– Turn the mode selector switch 11 to the "drilling" position.
Removing Drilling Tools without SDS-plus (see figure G)
– Firmly hold the rear sleeve 20 of the keyless chuck and
turn the front sleeve 19 of the keyless chuck in anticlock-
wise direction until the drilling tool can be removed.
Dust Extraction with the Dust Extraction Attach-
ment (Accessory)
Dust 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 dust can cause
allergic reactions and/or lead to respiratory infections of
the user or bystanders.
Certain dust, such as oak or beech dust, is considered car-
cinogenic, especially in connection with wood-treatment
additives (chromate, wood preservative). Materials con-
taining asbestos may only be worked by specialists.
– As far as possible, use a dust extraction system suitable
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. Dust can
easily ignite.
Mounting the Dust Extraction Attachment (see figure H)
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 I)
The required drilling depth X can also be adjusted when the
dust extraction attachment is mounted.
– 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 adjustment of the
drilling depth.
– Loosen the wing bolt 25 on the dust extraction attach-
ment.
