a relatively short impact duration (steep characteristic
curve). An unnecessarily long impact duration only
causes damage to the machine.
– A spring-loaded seat is used for metal-to-metal screw
applications that use spring washers, disc springs, studs
or screws/nuts with conical seats. It is also called a
spring-loaded seat when extensions are used.
– A soft seat is used for screw applications of e.g. metal on
wood or screw applications that use lead washers or fibre
washers as backing.
For a spring-loaded seat, as well as for a soft seat, the max-
imum tightening torque is lower than for a hard seat. A much
longer impact duration is also required.

Tips
Before screwing larger, longer screws into hard materials, it
is advisable to pre-drill a pilot hole with the core diameter of
the thread to approx. 2/3 of the screw length.
Note: Ensure that no metal particles enter the power tool.
Belt clip
You can use the belt clip (3) to hang the power tool on a belt,
for example. You then have both hands free and the power
tool is always at hand.
Recommendations for optimal handling of the battery
Protect the battery against moisture and water.
Only store the battery within a temperature range of -20 to
50 °C. Do not leave the battery in your car in the summer, for
example.
A significantly reduced operating time after charging indic-
ates that the battery has deteriorated and must be replaced.
Follow the instructions on correct disposal.
Maintenance and Servicing
Maintenance and Cleaning
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.
u
To ensure safe and efficient operation, always keep
the power tool and the ventilation slots clean.
