Section 3 – Maintenance
3.1
Maintenance Information
Breakdowns caused by insufficient and unprofessional maintenance can lead to very high repair costs
and long downtimes. Regular maintenance is essential. Operational safety and the service life of the
machine depend on several factors, including proper maintenance.
The following table contains information on schedules, inspections, and maintenance for normal
working. The times are based on daily use. If the number of working hours shown here is not reached in
the corresponding period, the period may be extended. However, a complete inspection must take
place every year.
Because operation conditions can vary considerably, it is not possible to state in advance how often
checks for wear, inspections, maintenance, and repairs are necessary. A practical inspection schedule
should be drawn up taking the operating conditions into account. Contact NFE if you require further
assistance.
Warning!
Before beginning any repair work on the machine, make sure that it is turned off and disconnected
from the power source.
