Turning the unit on and off
424 On/"off" switch
Turning on the unit: Push the on/"off" switch forward.
Turning off the unit: Push the on/"off" switch to the
rear.
Damage to property
The machine is equipped with an electronic
starting current limiter. Do not, therefore,
begin processing the workpiece until after
the machine has been turned on and has
reached maximum speed!
The machine must never be turned off
while the punch is in the workpiece when
the cutting tracks end in the workpiece. In
this case, guide the machine back along
the freshly cut track a few millimeters befo-
re turning it off.
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.
Cooling and lubrication
The cutting results are improved and the service life of
the punch is increased if
•
before machining the workpiece
the cutting track is coated with oil.
Recommended for steel:
Punching and nibbling oil, order no. 103387
Recommended for aluminium:
Wisura oil, order no. 125874

Changing the cutting direction
The tool (i.e. the cutting direction) can be turned 90° to
the left or right if necessary, e.g. if space is restricted.
•
Loosen the locking lever (15).
•
Turn the die carrier (1) 90° in the desired direction.
•
Close the locking lever (15).

Nibbling with a template
•
The template should be at least 5 mm thick.
•
The contour of the template should be 8.5 mm
away from the contour that is to be nibbled.
•
The nibbler must be guided in such a way that the
outside edge of the punch guide always rests a-
gainst the template.
•
Ensure that the radius is at least 90 mm!
Inner cutouts
Inner cutouts require a starting hole with a diameter of
at least 41 mm ∅ .
Die selection
One of the following four die types may be selected
depending on the thickness, tensile strength and type
of workpiece that is to be machined:
