The values given are valid for nominal voltages [U] of
230/240 V. For lower voltage and models for specific
countries, these values can vary.
Please observe the article number on the type plate of your
machine. The trade names of the individual machines may
vary.
Noise/Vibration Information
Measured values determined according to EN 60745.
Typically the A-weighted sound pressure level of the
machine is 80 dB(A). Uncertainty K=3 dB.
The noise level when working can exceed 85 dB(A).
Wear hearing protection!
The typically weighted acceleration is 3 m/s
The vibration emission level given in
WARNING
this information sheet has been meas-
ured in accordance with a standardised test given in
EN 60745 and may be used to compare one tool with
another.
The vibration emission level will vary because of the
ways in which a power tool can be used and may
increase above the level given in this information sheet.
This could lead to a significant underestimate of expo-
sure when the tool is used regularly in such a way.
Note: To be accurate, an estimation of the level of
exposure to vibration experienced during a given period
of work should also take into account the times when
the tool is switched off and when it is running but not
actually doing the job. This may significantly reduce the
exposure level over the total working period.

Auxiliary Handle
Screw the auxiliary handle 3 either at the right or the left
side of the housing into the thread 6.
Using the handle mount 2 you can extend the auxiliary
handle and pivot it, user-defined, in order to obtain a
secure and comfortable working position.
If the auxiliary handle 3 is already mounted, then
unscrew it from the thread 6. Tighten the handle mount
2 with the screw 1 in the desired angle at the right or
the left side of the housing in the screw thread 6. Cor-
respondingly screw the auxiliary handle at the right or
left side into the narrow end of the handle mount 2.
If you fix the handle mount at the left side of the housing
2
. make sure not to cover the On/Off switch 5.

Operation

Starting Operation
Adjust the hold down guide
To work without vibration, adjust the hold down guide
12 to the respective sheet thickness.
Hold the power tool in such a manner so that the lower
die 14 touches the under side of the sheet metal.
Loosen the screws 13 of the hold down guide. Push
the hold down guide 12 with a little play (approx.
0.3 mm) onto the sheet. Make sure that the hold down
guide is straight. Retighten the screws 13.

Certification
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.
