Noise/Vibration Information

Measured values determined according to
EN 60745.
Typically the A-weighted noise levels of the prod-
uct are: Sound pressure level 95 dB(A); Sound
power level 108 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values (triax vector sum) deter-
mined according to EN 60745:

The vibration emission level given in this informa-
tion sheet has been measured in accordance
with a standardised test given in EN 60745 and
may be used to compare one tool with another. It
may be used for a preliminary assessment of ex-
posure.
The declared vibration emission level represents
the main applications of the tool. However if the
tool is used for different applications, with differ-
ent accessories or poorly maintained, the vibra-
tion emission may differ. This may significantly
increase the exposure level over the total work-
ing period.
An estimation of the level of exposure to vibra-
tion should also take into account the times
when the tool is switched off or when it is run-
ning but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total
working period.
Identify additional safety measures to protect the
operator from the effects of vibration such as:
maintain the tool and the accessories, keep the
hands warm, organisation of work patterns.

Assembly
Changing the Tool
Before any work on the machine itself, pull
the mains plug.
When working with an application tool, pay
attention that the application tool is firmly
seated on the tool holder. When the applica-
tion tool is not firmly connected with the tool
holder, it can come loose again and not be
controlled.

Slide the application tool 6 onto the square drive
of the tool holder 5.
Operation
Method of Operation
The tool holder 5 with the tool is driven by an
electric motor via a gear and impact mechanism.
The working procedure is divided into two phas-
es:
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
mechanism converts the power of the motor to
steady rotary impacts. When loosening screws or
nuts, the process is reversed.
Overloading the motor is not possible, as the
hammer mechanism disengages when reaching
the rated load.

Starting Operation

Observe correct mains voltage! The voltage
of the power source must agree with the
voltage specified on the nameplate of the
machine. Power tools marked with 230 V can
also be operated with 220 V.
