Operating instructions
Check the tools for wear and the oil lubrication of the
compressed-air motor every hour.
Never work with blunt tools!
(the compressed-air motor may stop).
Turning the unit on and off
1 Lever
Turning on the unit: Press lever 1.
Turning off the unit: Release lever 1 (the lever
springs back into initial position and the flow of
compressed air is interrupted).
Do not begin machining 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 before
turning it off.
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 or sectional sheets are to be machined with
the bevelled die.
•
Unscrew clamping screw (22) by approx. 4 rota-
tions.
•
Turn tool head 90° in the desired direction.
•
Retighten the clamping screw (22).
Nibbling with a template
•
The template should be thick enough that the
overall thickness of the piece and template is
between 5 and 6.5 mm.
•
The contour of the template should be 2.5 mm
away from the contour that is to be nibbled.
•
The nibbler must be guided in such a way that
the outside edge (13 mm) of the punch guide
always rests against the template.
•
Ensure that a minimum radius of 4 mm (punch
radius) is maintained.
Inner cutouts
Inner cutouts require a starting hole with a diameter
of at least 16 mmØ.
Die selection
Two different punches may be used to machine diffe-
rent types of workpieces:
