SECTION 5
TROUBLESHOOTING
Faults are often due to the machine not having been
operated or serviced properly.
When dealing with faults, it is therefore necessary to
read the corresponding chapter of the operating
instructions once again.
If you cannot find the cause of a fault or rectify it,
contact the After-sales service.
Describe the fault and the accompanying circum-
stances as precisely as possible when contacting
our After-sales service. Exact information helps to
locate and to rectify faults as fast as possible.
Never do work for which you are not qualified.
The present fault table lists the faults reported to
date, their possible causes and the remedial action.
In exceptional cases, a described fault may also
have another cause.
FAULT
The fault is described as a result of an observation
or of a preceding activity.
Observe the machine carefully.
Examine the problem thoroughly.
Ask yourself the following questions:
- Which warning signs preceded the fault?
- Which repair and maintenance work had been
performed beforehand?
- Has this defect already been noticed in the past?
- Are we faced with one or with several defects
occurring at the same time?
POSSIBLE CAUSES
This column describes the possible causes of the
fault observed. The causes are listed in the order of
their probability of occurrence, the possible cause
applying in most of the cases is mentioned in first
place.
CORRECTION

of faults and how to remedy them.
