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 di-
rection  and push the auxiliary handle 10 forward until you
can pivot it to the desired position. Then pull the auxiliary han-
dle 10 back again and tighten it by turning the bottom part of
the auxiliary handle in rotation direction .
Adjusting the Drilling Depth
The required drilling depth X can be set with the depth stop 7.
Loosen the wing bolt for the depth stop adjustment 9 and in-
sert the depth stop rod 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.
Retighten the wing bolt for the depth stop adjustment 9 again.
Changing the Tool
 Wear protective gloves when changing the tool. The
drill chuck can become very hot during longer work peri-
ods.
Key-type Drill Chuck with Automatic Locking Feature
(see figure D)
Open the key type drill chuck 1 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 1 and clamp the tool uniformly.
Key-type Drill Chuck (Manual Locking) (see figure E)
Open the key type drill chuck 16 by turning until the tool can
be inserted. Insert the tool.
Insert the chuck key 15 into the corresponding holes of the
key type drill chuck 16 and clamp the tool uniformly.
With the hexagon of the chuck key 15, turn the den eccentric
cam to the stop in rotation direction . This ensures the ten-
sioning force.
For removal of the application tool, turn the eccentric cam in
rotation direction  and open the key-type drill chuck 16
with the chuck key 15.
Screwdriver Tools
When working with screwdriver bits 13, a universal bit holder

Replacing the Drill Chuck
Removing the Drill Chuck (see figure F)
To dismount the key type drill chuck 1, position an open-end
spanner 17 (size 17 mm) against the spanner flats of the
drive spindle.
Place the machine on a firm support, e.g., a workbench. Insert
the chuck key 12 into one of the three holes of the key type
drill chuck 1 and release the key type drill chuck 1 with this le-
ver by turning in rotation direction . Loosen a tight seated
key type drill chuck with a light blow on the chuck key 12. Re-
move the chuck key 12 from the key type drill chuck and com-
pletely unscrew the key type drill chuck.
Mounting the Drill Chuck (see figure G)
The key type drill chuck is mounted in reverse order.
The drill chuck must be tightened with a tightening
torque of approx. 53–61 Nm.

Dust/Chip Extraction

 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.
– 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 mate-
rials to be worked.
 Prevent dust accumulation at the workplace. Dusts can
easily ignite.
Operation

Starting Operation

 Observe correct mains voltage! The voltage of the pow-
er source must agree with the voltage specified on the
nameplate of the machine. Power tools marked with
230 V can also be operated with 220 V.
Reversing the rotational direction (see figures H–I)
The rotational direction switch 3 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 5 actuated.
Right rotation: For drilling and screwing in screws, push the
rotational direction switch 3 toward the left.
Left rotation: For loosening and unscrewing screws and
nuts, push the rotational direction switch 3 toward the right.
