Rotary compressor/compressor and vacuum
pump
Guarantee
We are sure you will appreciate that we can accept no
liability for damage caused by non-observance of the
installation and operating instructions.
Please note that repairs to the rotary compressors or
the compressors and vacuum pumps must only be
carried out by authorized repair workshops, using only
original spare parts, as the guarantee otherwise loses
its validity. A list of our after-sales service centres is
part of the complete documentation.
Maintenance, maintenance plan
In maintenance and inspection work the
safety regulations (
chapter
) must be
adhered to.
Operational failures due to insufficient or incorrect
maintenance can cause extremely high repair costs
and
long machine
standstill
periods.
Regular
maintenance is therefore essential.
Operational reliability and the service life of the
machine depend largely on correct maintenance.
The below table contains timing, checking and
maintenance information for normal operation of the
machine.
The maintenance intervals given are based on an
operating time of approx. 5 hours per day. If this
operating time is not reached, the maintenance
intervals can be extended accordingly.
Because of the differing operating conditions it cannot
be predicted how often checks of wear and tear,
repair,
maintenance and inspection
work
are
necessary. On the basis of your operating conditions it
is recommended that an inspection plan to suit your
circumstances is drawn up.
After work is completed, all protective devi-
ces must be fitted again.
When disposing of oil, grease, cleansing
solvents
or
components,
e.g.
filter
cartridges, the environmental protection
regulations must be observed.
