Intended Use

The machine is intended for cutting sheet metals
without loss due to metal chips. It is suited for
curved and straight cutting.

Initial Operation

Check for correct mains voltage: The voltage
of the power source must agree with the voltage
specified on the nameplate of the machine.
Equipment marked with 230 V can also be con-
nected to 220 V.

Switching On and Off

Switching on: Push the On/Off switch 1
backwards.
Switching off: Push the On/Off switch 1
forwards.
Operating Instructions
Apply the machine to the workpiece only
when switched on.
Guide the machine raised at the front at an angle
of 10° to 15° from the surface of the sheet metal.
Do not tilt the machine to the side.
Do not load the machine so heavily that it comes
to a standstill.
Cutting curves: Do not tilt the machine and work
only with a low feed rate.
Before starting to cut, lightly oil the cutting line on
the sheet metal.
Sharp cutters result in good cutting performance
and protect the machine.
Never cut with blunt cutters.
Both sides of the upper cutter 5 supplied with the
machine can be used.

Replace or sharpen the cutters as required.
A high feed rate significantly decreases the per-
formance capability of the machine and reduces
the service life of the cutters.

Changing the Tool

A
Before any work on the machine itself, pull
the mains plug.
Lower Cutter
Loosen the nut 8. Remove the set screw 9. Insert
the lower blade 7 into the relief of the blade
holder 3 and tighten it with the screw 10.
Upper Cutter
Insert the upper cutter into the plunger and
tighten with the screw 6.

Adjusting the Cutters

Cutter Clearance a
The cutter clearance a (air gap be-
tween the cutters) depends on the
thickness of the material to be cut.
a
Cutter Clearance a
0.3 mm
0.5 mm
0.7 mm
0.9 mm
For softer or more ductile materials, the clear-
ance a must be decreased; for harder or more
brittle materials, increased.
Remove the nut 8. Loosen the screw 10 and set
the lower blade 7 to the required blade distance a
with the set screw 9. Check the distance with the
aid of the setting gauge 14. Re-tighten the
screw 10. Fasten the nut 8.
