ly prior to operation, however, the vibration and noise load may be
higher when the tool is used�
Take into account any machine idling times and downtimes to esti-
mate these values more accurately for a specified time period� This
may significantly reduce the load during the machine operating
period�

Use

Cordless impact wrenches are designed for loosening and tight-
ening nuts and screws without the need for a power outlet� They
can also be used for driving screws, marginally for drilling into
wood, metal and plastic� The user is responsible in cases, where
the wrench is used for purposes other than those for which it was
intended�

Double insulation

To ensure maximum safety of the user our tools are designed and
built to satisfy applicable European standards (EN standards)� Tools
with double insulation are marked by the international symbol of
a double square� These tools must not be grounded and a two-wire
cable is sufficient to supply them with power� Tools are shielded in
accordance with EN 55014�
Accumulator Battery Charge
Instructions
1� Please make sure that the power supply is the same as the
voltage listed on the manufacturer label on the charger� Con-
nect the charger (8) to the power source� A red LED indicator
light (9) comes on� This means that the charger is ready to be
charged� Please check the power source connection if the red
LED indicator light does not come on� If the power source is
OK, bring the charger in for repair to an authorised service cen-
tre�
2� Slide the battery (1) into the charger all the way�
3� The red LED indicator light turns off and a green LED indicator
light (9) begins blinking, indicating that the battery is in fast
charge mode�
4� The battery is fully charged after about 25 to 30 minutes (de-
pending on the battery capacity) once the green LED indicator
light stops blinking and remains lit�
5� Disconnect the battery from the charger� If you do not wish to
charge another battery, disconnect the charger from the pow-
er source�

* When the charger is activated after it is connected to power, the red and the
green LED indicator lights will blink for about 1 second, then the red LED indica-
tor light will stop blinking and remain on (constant light).
New batteries:
Battery capacity may be slightly smaller than the listed value dur-
ing the first few initial charge cycles� The reason is that the chem-
ical composition of the batteries has not been activated yet� This
is a temporary issue and will resolve on its own after a few charge
cycles�
Note:
• A blinking green indicator means that the battery is fully
charged or that it is in slow charge mode, which maintains a
low charge level of the battery�
• The initial battery charge may take longer than 25 to 30
minutes (according to battery capacity) depending on the
20
• If you are not using the charger, please unplug it from the pow-
