Technical Data
Noise/Vibration Information
Measured sound values determined according to EN 60745.
Typically the A-weighted noise levels of the product are:
Sound pressure level 95 dB(A); Sound power level
108 dB(A). Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values a
h
(triax vector sum) and uncertainty K
determined according to EN 60745:
Impact tightening of fasteners of the maximum capacity of the
tool: a
h
=4 m/s 2 , K=0,5 m/s 2 .
The vibration emission level given in this information 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 expo-
sure.
The declared vibration emission level represents the main ap-
plications of the tool. However if the tool is used for different
applications, with different accessories or poorly maintained,
the vibration emission may differ. This may significantly in-
crease the exposure level over the total working period.
An estimation of the level of exposure to vibration should also
take into account the times when the tool is switched off or
when it is running but not actually doing the job. This may sig-
nificantly reduce the exposure level over the total working pe-
riod.
Identify additional safety measures to protect the operator
from the effects of vibration such as: maintain the tool and the
accessories, keep hands warm, organise work patterns.
Declaration of Conformity
We declare under our sole responsibility that the product de-
scribed under “Technical Data” is in conformity with the fol-
lowing standards or standardization documents: EN 60745
according to the provisions of the directives 2011/65/EU,
2004/108/EC, 2006/42/EC.

Assembly
Changing the Tool
f Before any work on the machine itself, pull the mains
plug.
f When working with an application tool, pay attention
that the application tool is firmly seated on the tool
holder. When the application tool is not firmly connected
with the tool holder, it can come loose again and not be
controlled.
– Slide the application tool 1 onto the square drive of the tool
holder 2.
Operation
Method of Operation
The tool holder 2 with the 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 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 mecha-
nism disengages when reaching the rated load.
Starting Operation
f Observe correct mains voltage! The voltage of the pow-
er 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.
Reversing the rotational direction (see figure A)
The rotational direction switch 7 is used to reverse the rota-
tional direction of the machine. However, this is not possible
with the On/Off switch 5 actuated.
– Right rotation:
Press the rotational direction switch 7 rightward
to the stop.
– Left rotation:
Press the rotational direction switch 7 leftward
to the stop.
