1. General information
NOTE
Always first identify the cause of any malfunction.
Safety precautions
Machine malfunctions must only be rectified by qualified
staff instructed to do so by the person responsible.
When identifying the source of malfunction, attention must
be paid to the entire area surrounding the machine. The
manufacturer must be immediately notified of any damage
occurring during the warranty period.
WARNING
Safety regulations while identifying the source of
malfunction and rectifying malfunction.
Observe the accident prevention regulations!
• In the event of a mechanical malfunction, make sure
that the assembly jig is depressurized.
• Prevent the machine from switching back on again and
attach a warning sign.
2. Malfunctions caused by the owner
Before leaving the factory, the machine/system was checked
for proper working order by our skilled personnel.
Malfunctions attributable to improper treatment, non-
intended use or poor (unpunctual / improper) servicing are not
covered by the warranty. The risk is borne solely by the owner.
3. Troubleshooting
CAUTION
Observe the regulations, warnings and precautions
when carrying out any troubleshooting activity
When locating any fault, proceed in stages and make a
written note of observations, testing or measuring results.
Try and establish as accurately as possible which operating
situation the malfunction occurred in, in other words try and
answer the following questions:
Which work operation was the machine still performing
properly?
After which work operation did the malfunction start to
occur?
Does the malfunction occur regularly or only occasionally?
In the case of occasional malfunctions, try to find out
whether the malfunction can be associated with events or
actions immediately before the malfunction occurs.
Does the malfunction only occur in conjunction with specific
components (material, shape, particular profiles)?
Observe the operating manuals for all additional equipment /
options.
General causes of malfunction
Before removing components in any troubleshooting activity,
first check whether:
•
the machine and / or its equipment is not showing any
visible damage
• the machine is clean and no dust deposits are obstructing
or affecting the way components move
• the compressed-air supply is working properly and the
operating pressure is within the permissible tolerance (6 - 7
bar)
• the mains power supply conditions match the specifications
for the electric motors (rating plates) and / or electric
equipment, and motor protection is correctly set
• servicing measures have been performed on time
Malfunctions while machine is operating
All work involved in repairing, setting, troubleshooting and
servicing must only be carried our by duly instructed, trained

Try and locate the area of the machine the malfunction has
occurred in.
