Assembly
Removing the Battery (see figure A)
Note:
The battery supplied is partially charged. To
ensure full capacity of the battery, completely char-
ge the battery in the battery charger before using
your power tool for the first time.
The lithium-ion battery can be charged at any time
without reducing its service life. Interrupting the
charging procedure does not damage the battery.
The lithium-ion battery is protected against deep
discharging by the Electronic Cell Protection
(ECP). When the battery is empty, the machine is
switched off by means of a protective circuit: The
inserted tool no longer rotates.
Do not continue to press the On/Off switch af-
ter the machine has been automatically swit-
ched off.
The battery can be damaged.
To remove the battery
8
press the unlocking but-
tons
7
and pull out the battery downwards.
Do not
exert any force.
Observe the notes for disposal.
Changing the Tool
Before any work on the machine itself (e. g.
maintenance, tool change, etc.) as well as du-
ring transport and storage, remove the battery
from the power tool.
There is danger of injury
when unintentionally actuating the On/Off
switch.
Regularly clean the power tool’s air vents.
The
motor’s fan will draw the dust inside the housing
and excessive accumulation of powdered metal
may cause electrical hazards.
Inserting (see figure B)
Pull the locking sleeve
2
forward, push the insert
tool to the stop into the tool holder
1
and release
the locking sleeve
2
to lock the insert tool.
Screwdriver bits
15
can be inserted using a univer-
sal bit holder with ball lock
14
.
Removing
Pull the locking sleeve
2
forward and remove the in-
sert tool.
Operation
Method of Operation
The tool holder
1
with the tool is driven by an elec-
tric motor via a gear and impact mechanism.
The working procedure is divided into two phases:
Screwing in
and
tightening
(impact mechanism in
action).
The impact mechanism is activated as soon as the
screwed connection runs tight and thus load is put
on the motor. In this instance, the impact mecha-
nism converts the power of the motor to steady ro-
tary impacts. When loosening screws or nuts, the
process is reversed.
Starting Operation
Inserting the battery
Set the rotational direction switch
9
to the centre
position to protect the power tool against acciden-
tal starting.
Insert the charged battery
8
from the front into the
base of the power tool until the battery is securely
locked.
Reversing the rotational direction (see figure C)
The rotational direction switch
9
is used to reverse
the rotational direction of the machine. However,
this is not possible with the On/Off switch
10
actu-
ated.
Right rotation:
For driving in screws and tightening
nuts, press the rotational direction switch
9
through to the left stop.
Left Rotation:
For loosening and unscrewing
screws and nuts, press the rotational direction
switch
9
through to the right stop.
Switching On and Off
To
start
the machine, press the On/Off switch
10
and keep it pressed.
To
switch off
the machine, release the On/Off
switch
10
.
To save energy, only switch the power tool on
when using it.
