Operation

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.
Switching On and Off
To start the machine, push the On/Off switch 1
forward so that the "I" is indicated on the switch.
To switch off the machine, push the On/Off
switch 1 toward the rear so that the "0" is indi-
cated on the switch.

Working Advice

Apply the power tool to the workpiece only when
switched on.
Hold the power tool inclined in an angle of 15° to
the surface of the steel sheet and do not tilt it lat-
erally.
Guide the machine evenly and with light feed in
the cutting direction. Excessive feed significantly
reduces the service life of the saw blade and can
cause damage to the power tool.
Wear protective gloves while working and
pay particular attention to the mains cable.
Sharp burrs develop at the cut steel sheet and
can cause injuries to the operator or damage
the mains cable.
When cutting curves, make sure not to tilt the pow-
er tool laterally and work with low feed rate only.

The machine allows for cutting of metal sheet to
the following thicknesses:

Loosen the fastening screw 12 for the bottom
cutter. Adjust the requested cutter clearance a
with the adjustment screw 11. The upper cutter
7 and the bottom cutter 9 may not touch each
other. Check the clearance with the setting
gauge 13. Retighten the fastening screw 12 for
the bottom cutter.
