Operating instructions
Damage to property!
Check the tools for wear every hour.
Never work with blunt tools,
as this could otherwise overload the machine!
Turning the unit on and off
0
On Off
Damage to property!
Do not begin machining the workpiece until
after the machine has been turned on and
has reached maximum speed!
Guide the unit towards the sheet surface at an angle
of 80° to 90° (figure).
80° - 90°
Do not overload the unit and cause it to stop.
Excessive feed significantly reduces the service life of
the cutters and can damage the unit.
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
Moving cutter blade (top cutter) and fixed cutter blade
(bottom cutter) have the same shape and are mutually
(top or bottom) interchangeable. All cutters have 4
cutting edges. These are not regrindable "fourfold-
reverse blades". 2 different cutter types may be
selected from the following table according to the
thickness, tensile strength and type of workpiece that
is to be machined:
Cutter-Type Order No.
Standard* 127911
** Cr 919761
* The standard cutter for material consistencies up
2
to 400 N/ mm does not have a special type label.
** Cutter type "Cr" = chrome-steel cutter with
optimised cutter geometry, suitable for steels
> 400 N/mm²
Damage to property!
Risk of fracture!
It is urgently recommended that tools be used
according to the specifications found in the
table.
Replacing Cutters
Danger of injury!
Pull the plug out of the socket.
Turn the cutters 90° or replace them if cutting power is
insufficient.
To turn the cutters, loosen the screw on the respective
cutter; turn the cutter 90° and retighten the screw.
Ensure that the adjusting screw (19) on the bottom
cutter fits closely.
