The machine is equipped with an elec-
tronic starting current limiter. Do not, the-
refore, begin processing the workpiece
until after the machine has been turned
on and has reached maximum speed!
The unit could switch off prematurely if
electromagnetic interference acts upon it
for a long time. Once the interference
dies away the unit will continue to work.
Guide the unit towards the sheet surface at an angle
of 80° to 90° (figure).
Sharp cutters always cut well and are easy on the
machine. Always turn or replace the cutters in good
time.
Cutting radii: Do not tilt the machine and work with
minimal feed.
Work upside down with the fixed blade carrier pointing
upward when cutting along the edge, particularly
during precision cutting along a scribed line.
Cutter selection
All cutters have 2 cutting edges. Cutters may be
selected from the following table according to the
thickness, tensile strength and type of workpiece that
is to be machined:
Fixed cutter blade (cutter for material strengths < 400
5
N/mm² does not have a special marking)
7 Moving cutter blade, type 3, type 4, type Cr
Cutters with type markings

* The fixed cutter blade for material strengths of up
to 400 N/mm² does not have a special type
marking.
( ) Can be used, but subject to increased wear!
Warning!
If the cutter or combination of cutters is not properly
selected according to the table
•
it may be impossible to machine thin sheets under
certain circumstances,
•
the individual tools may be overloaded when
machining thick sheets.
Risk of fracture!
It is therefore urgently recommended that tools be
combined according to the specifications found in the
table.
