Assembly
f
Before any work on the machine (e. g.,
maintenance, tool change, etc.) as well as
during transport and storage, set the rota-
tional direction switch to the centre posi-
tion.
Unintentional actuation of the On/Off
switch can lead to injuries.
Battery Charging
A battery that is new or has not been used for a
longer period does not develop its full capacity
until after approx. 5 charging/discharging cy-
cles.
To remove the battery
11
, press the battery re-
lease button
14
and pull the battery downward
out of the power tool.
Do not exert any force.
(see figure A)
The battery is equipped with a NTC temperature
control which allows charging only within a tem-
perature range of between 0 °C and 45 °C. A
long battery service life is achieved in this man-
ner.
A significantly reduced working period after
charging indicates that the battery is used and
must be replaced.
Observe the notes for disposal.
Battery Charge-control Indication
The battery charge-control indicator
10
indi-
cates the charge condition of the battery
11
dur-
ing the working procedure.
Push button
9
to indicate the charge condition
when the battery is removed or when the power
tool is switched off. The battery charge-control
indicator automatically goes out after approx.
5 seconds.
When the first indicator element (0
– 10%)
flashes, the battery is almost completely dis-
charged and must be recharged again.
Discharge the battery occasionally until the
speed of the power tool reduces significantly
and the battery charge-control indicator
10
completely goes out. Frequent charging after
short-term usage impairs the indication accura-
cy and the service life of the battery.
Auxiliary Handle
f
Operate your machine only with the auxilia-
ry handle 12.
The auxiliary handle
12
can be set to any position
for a secure and low-fatigue working posture.
Turn the bottom part of the auxiliary handle
12
in counterclockwise direction and swivel the
auxiliary handle
12
to the desired position. Then
retighten the bottom part of the auxiliary handle
12
by turning in clockwise direction.
Adjusting the Drilling Depth (see figure C)
The required drilling depth
X
can be set with the
depth stop
13
.
Press the button for the depth stop adjustment
5
and insert the depth stop into the auxiliary
handle
12
.
Insert the SDS-plus drilling tool to the stop into
the SDS-plus tool holder
1
. Otherwise, the mov-
ability of the SDS-plus drilling tool can lead to
incorrect adjustment of the drilling depth.
Pull out the depth stop until the distance be-
tween the tip of the drill bit and the tip of the
depth stop correspond with the desired drilling
depth
X
.
The knurled surface of the depth stop
13
must
face upward.
