Push button 13 to indicate the charge condition (also possi-
ble when the battery is removed). The battery charge-control
indicator automatically goes out after approx. 5 seconds.
LED
Continuous lighting 3 x green
Continuous lighting 2 x green
Continuous lighting 1 x green
Flashing light 1 x green
When no LED lights up after pushing button 13, then the bat-
tery is defective and must be replaced.
During the charging procedure, the three green LEDs light up
one after the other and briefly go out. The battery is fully
charged when the three green LEDs light up continuously. The
three LEDs go out again approx. 5 minutes after the battery
has been fully charged.
The battery is equipped with a NTC temperature control
which allows charging only within a temperature range of be-
tween 0 °C and 45 °C. A long battery service life is achieved
in this manner.
Auxiliary Handle (see figure B)
Before any work on the machine (e. g., maintenance,
tool change, etc.) as well as during transport and stor-
age, set the rotational direction switch to the centre
position. Unintentional actuation of the On/Off switch can
lead to injuries.
Operate your machine only with the auxiliary handle 7.
The auxiliary handle 7 can be set to any position for a secure
and low-fatigue working posture.
Turn the bottom part of the auxiliary handle 7 in counterclock-
wise direction and swivel the auxiliary handle 7 to the desired
position. Then retighten the bottom part of the auxiliary han-
dle 7 by turning in clockwise direction.
The clamping band 15 of the auxiliary handle must be seated
in the corresponding groove.
Changing the Tool (see figure C)
Before any work on the machine (e. g., maintenance,
tool change, etc.) as well as during transport and stor-
age, set the rotational direction switch to the centre
position. Unintentional actuation of the On/Off switch can
lead to injuries.
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 direction
until the tool can be inserted. Insert the tool.
Firmly tighten the collar of the keyless chuck 1 by hand in ro-
tation 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 col-
lar is turned in the opposite direction.

Hold the machine firmly and loosen the keyless chuck 1 by
turning the Allen key 18 in rotation direction
tight-seated keyless chuck by giving the long end of the Allen
key 18 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 is mounted in reverse order.
Note: After mounting the keyless chuck, screw the securing
screw 17 in again.
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
materials to be worked.
Prevent dust accumulation at the workplace. Dusts can
easily ignite.
