Putting in operation
Make sure the information on the factory tag
corresponds with the actual voltage of the power
source.
Make sure the socket plug type is compatible
with the type of socket.
The tools designed for 230 V can be connected
also to 220/240 V.
Power On – Power Off
Slide the switch button (1) forward to turn the
machine on. If you press the front part of the
button it will lock, thus achieving constant run.
Press the rear part of the switch button shortly
(1) to unlock the button and return it to the Off
position by the pressure of the spring.
Work instructions
Default number of lifts
Using the controller (6), you can preset the
desired number of lifts even in run.
1 – 2 low number of lifts
3 – 4 medium number of lifts
5 – 6 high number of lifts
Required number of lifts depends on the type
and rigidity of material, and can be found out
through a practical test. Sheet metals that get
near the maximum thickness and rigidity to be
cut using level 6. After a longer work with low
number of lifts leave the machine in idle run for
1 – 3 mins at maximum number of lifts (level 6).
It is only possible to work with lower level
than 4 on low-rigid and thin materials.
ATTENTION!
When working with lower control level, the
engine cooling gets worse and thus the
possibility of overheating increases.
Punch and matrix adjustment
Make sure the punch and matrix are sharp.
ATTENTION!
Never cut using a blunt punch or matrix! This
could result in damaging the punch (chipping
the cutting edge) and its devaluation.
Using a screwdriver inserted in the eccentric
spindle groove (14) crank the spindle whilst
checking the depth of the punch immersion (12)
into the matrix (9). The depth of punch immer-
sion (12) should be 0.5 – 1.5 mm. In the top
dead centre the punch (12) must not stick out
from the guide of the punch (10). A new machine
is adjusted by the manufacturer. Make sure the
clamp bolt is tightened properly.
Cutting
ATTENTION!
Before mounting to the cut sheet metal, the
punch must be running. The machine must not
be fitted in the cut and only then put in opera-
tion. What to lay on the cut spot of sheet metals:
• steel sheet metals – oil
• aluminous – petroleum
Use cutting oil to enhance the quality of the
cutting edge.
Do not force the punch in the cut.
Punching
When punching shapes inside the board drill a
∅ 18 mm hole first. Start to punch in any direc-
tion from that hole.
Punching using a template
When punching using a template, the thickness
of the cut sheet metal needs to be in range from
5 to 6.5 mm, thickness included. The contour of
the template needs to have a 2.5 mm spacing
from the cut contour. Guide the punch so that
Motor electronics
Starting current limitation
Electronically controlled continual running secures
device acceleration without back thrust. Due to
starting current limitation in the device, 10A pro-
tection is sufficient.
Protection against re-starting
Prevent uncontrolled starting of the device after
current supply cut off. For re-starting, the device
must be first switched off and again switched on.
