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.
