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 rota-
tion direction ‹ and push the auxiliary handle 10 for-
ward until you can pivot it to the desired position. Then
pull the auxiliary handle 10 back again and tighten it by
turning the bottom part of the auxiliary handle in rota-
tion 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 corre-
spond 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 possible.
Open the keyless chuck 1 by turning in rotation direc-
tion ‹, 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 uni-
formly.

Screwdriver Tools (see figure D)
When working with screwdriver bits 14, a universal bit
holder 15 should always be used. Use only screw-
driver bits that fit the screw head.
For driving screws, always position the "Drill-
ing/Impact 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 spin-
dle neck in order to lock the drill spindle.
Clamp the short end of an Allen 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 key-
less chuck 1 by turning the Allen key 16 in rotation
direction ‹. Loosen a tight-seated keyless chuck by
giving the long end of the Allen key 16 a light blow.
Remove the Allen 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 com-
pleted.
The drill chuck must be tightened with a
tightening torque of approx. 40–45 Nm.
Dust/Chip Extraction
¢ Dusts from materials such as lead-containing coat-
ings, 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 con-
sidered as 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.
