Assembly
Before any work on the machine itself, pull the
mains plug.
Auxiliary Handle (see figure A)
Operate your machine only with the auxiliary
handle 10.
The auxiliary handle 10 can be set in 12 positions
to achieve a safe and low-fatigue working stance.
Turn the bottom part of the auxiliary handle 10 in
rotation direction and push the auxiliary handle
10 forward until you can pivot it to the desired po-
sition. Then pull the auxiliary handle 10 back again
and tighten it by turning the bottom part of the aux-
iliary handle in rotation direction .
Adjusting the Drilling Depth (see figure A)
The required drilling depth X can be set with the
depth stop 11.
Press the button for the depth stop adjustment 9
and insert the depth stop into the auxiliary handle
10.
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.
The knurled surface of the depth stop 11 must face
upward.
Changing the Tool
Wear protective gloves when changing the
tool. The drill chuck can become very hot during
longer work periods.
Keyless Chuck (see figure B)
The drill spindle is locked when the On/Off switch
6 is not pressed. This makes quick, convenient and
easy changing of the tool in the drill chuck possi-
ble.
Open the keyless chuck 1 by turning in rotation di-
rection , until the tool can be inserted. Insert the
tool.
Firmly tighten the collar of the keyless chuck 1 by
hand in rotation direction until the locking action
("click") is no longer heard. This automatically
locks the chuck.
The locking is released again to remove the tool
when the collar is turned in the opposite direction.
Key Type Drill Chuck (see figure C)
Open the key type drill chuck 13 by turning until the
tool can be inserted. Insert the tool.
Insert the chuck key 12 into the corresponding
holes of the key type drill chuck 13 and clamp the
tool uniformly.

Screwdriver Tools (see figure D)
When working with screwdriver bits 14, a universal
bit holder 15 should always be used. Use only
screwdriver bits that fit the screw head.
For driving screws, always position the "Drilling/Im-
pact Drilling" selector switch 2 to the "Drilling"
symbol.
Replacing the Drill Chuck
Removing the Drill Chuck (see figure E)
Disassemble the auxiliary handle and set the gear
selector 8 to the centre position between the 1st
and 2nd gear.
Insert a steel pin with a diameter of Ø 4 mm and
approx. 50 mm of length into the drill hole on the
spindle neck in order to lock the drill spindle.
Clamp the short end of a hex key 16 into the key-
less chuck 1.
Place the machine on a stable surface (e. g. a work-
bench). Hold the machine firmly and loosen the
keyless chuck 1 by turning the hex key 16 in rota-
tion direction . Loosen a tight-seated keyless
chuck by giving the long end of the hex key 16 a
light blow. Remove the hex key from the keyless
chuck and completely unscrew the keyless chuck.
Mounting the Drill Chuck (see figure F)
The keyless chuck/key type drill chuck is mounted
in reverse order.
Remove the steel pin from the drill hole on the
spindle neck after mounting is completed.
The drill chuck must be tightened with a
tightening torque of approx. 40–45 Nm.
Dust/Chip Extraction
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 reac-
tions and/or lead to respiratory infections of the
user or bystanders.
Certain dust, such as oak or beech dust, is con-
sidered carcinogenic, especially in connection
with wood-treatment additives (chromate, wood
preservative). Materials containing asbestos may
only be worked by specialists.
– Provide for good ventilation of the working
place.
– It is recommended to wear a P2 filter-class res-
pirator.
Observe the relevant regulations in your country for
the materials to be worked.
Prevent dust accumulation at the workplace.
Dust can easily ignite.
