increase the vibration and noise emissions over the total
working period.
To estimate vibration and noise emissions accurately, the
times when the tool is switched off or when it is running but
not actually being used should also be taken into account.
This may significantly reduce vibration and noise emissions
over the total working period.
Implement additional safety measures to protect the oper-
ator from the effects of vibration, such as servicing the
power tool and application tools, keeping their hands warm,
and organising workflows correctly.
Assembly
u
Remove the battery from the power tool before carry-
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage.
There is risk of injury
from unintentionally pressing the on/off switch.
Battery Charging
Note:
The battery is supplied partially charged. To ensure
full battery capacity, fully charge the battery in the 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 process
does not damage the battery.
The lithium-ion battery is protected against deep discharge
by the "Electronic Cell Protection (ECP)". When the battery
is discharged, the power tool is switched off by means of a
protective circuit: The application tool no longer rotates.
u
Do not continue to press the On/Off switch after the
power tool has automatically switched off.
The battery
can be damaged.
– To remove the battery
(4)
, press the release button
(3)
and pull the battery back and out of the power tool.
Do
not use force to do this.
Changing the tool (see figure A)
u
Remove the battery from the power tool before carry-
ing out work on the power tool (e.g. maintenance,
changing tool, etc.). The battery should also be re-
moved for transport and storage.
There is risk of injury
from unintentionally pressing the on/off switch.
Inserting the application tool
– Pull the locking sleeve
(2)
forward, guide the application
tool
(1)
into the tool holder up to the stop and release the
locking sleeve
(2)
to lock the application tool.
– Use only screwdriver bits with ball catch
(8)
(DIN 3126-
E6.3). Other screwdriver bits
(9)
can be inserted using a
universal bit holder with ball catch
(10)
.
Removing the application tool
– Pull the locking sleeve
(2)
forward and remove the applic-
ation tool.
Operation
Method of Operation
The tool holder
(1)
(with the application tool) is driven by an
electric 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 load is therefore put on the motor.
The impact mechanism then converts the power of the mo-
tor to steady rotary impacts. When loosening screws or nuts,
the process is reversed.
Starting Operation
Inserting the Battery
Set the rotational direction switch
(5)
to the middle position
to avoid unintentionally switching it on. Insert the charged
battery
(4)
into the handle until you feel it engage and it is
flush with the handle.
Set the rotational direction (see figure B)
The rotational direction switch
(5)
is used to change the ro-
tational direction of the power tool. However, this is not pos-
sible while the on/off switch
(6)
is being pressed.
Right rotation:
To drive in screws and tighten nuts, press
the rotational direction switch
(5)
through to the left stop.
Left Rotation:
To loosen and unscrew screws and nuts,
press the rotational direction switch
(5)
through to the right
stop.
Switching on/off
To
start
the power tool, press and hold the on/off switch
(6)
.
To
switch off
the power tool, release the on/off switch
(6)
.
Adjusting the Speed
You can adjust the speed of the power tool when it is on by
pressing in the on/off switch
(6)
to varying extents.
A light pressure on the on/off switch
(6)
results in a low rota-
tional speed. Increased pressure on the switch causes an in-
crease in speed.
Temperature-dependent overload protection
In normal conditions of use, the power tool cannot be over-
loaded. If the power tool is overloaded or the permitted bat-
tery temperature is exceeded, the electronics of the power
tool will switch off until the temperature returns to within the
optimum operating temperature range.
Practical advice
u
Only apply the power tool to the screw/nut when the
tool is switched off.
Rotating tool inserts can slip off.
The torque depends on the impact duration. The maximum
achieved torque results from the sum of all individual
torques achieved through impact. Maximum torque is
achieved after an impact duration of 6–10 seconds. After
this duration, the tightening torque is increased only minim-
ally.
