Noise/Vibration Information

Measured sound values determined according to EN 60745.
Typically the A-weighted noise levels of the product are:
Sound pressure level 83 dB(A); Sound power level 94 dB(A).
Uncertainty K =3 dB.
Wear hearing protection!
Vibration total values a (triax vector sum) and uncertainty K

The vibration 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 anoth-
er. It may be used for a preliminary assessment of exposure.
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 insertion tools or is
poorly maintained, the vibration emission may differ. This
may significantly increase 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
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 pat-
terns.

Auxiliary Handle
/ II
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. Correspondingly screw the auxiliary
handle at the right or left side into the narrow end of the han-
dle mount 2.
If you fix the handle mount at the left side of the housing make
sure not to cover the On/Off switch 5.
Operation
Starting Operation
 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.
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.
Switching On and Off
To start the machine, push the On/Off switch 5 forwards.
To lock the On/Off switch 5, additionally push down the front
of the switch.
To switch off the machine, release the On/Off switch 5. When
the On/Off switch is locked, press on the rear of the switch
and then release it.
To save energy, only switch the power tool on when using it.
