NOTICE!
Damage due to faulty gaskets
Do not continue using used gaskets. Doing this will lead to
leakages within a short period of time.
–
Only re-install valves, cylinder heads and cylinders with
new gaskets.
NOTICE!
Damage due to low quality spare parts
Installation of low quality spare parts may lead to leakages
and may cause substantial damage to the compressor
.
– Use only genuine Sauer spare parts. They are precision
parts specially designed for these installation situations
with defined and tested dimensions and material charac-
teristics.
NOTICE!
Damage due to faulty valves
Do not repair used valves. Valves that have reached the end
of their service life must be replaced and disposed of.
–
Use only genuine Sauer spare parts.
Valves are exposed to the greatest loads of all the parts of a
piston compressor
. In order to achieve the guaranteed main-
tenance intervals, these valves are high-quality precision
parts, specially adapted to the individual compression stages
and their function carefully checked before delivery.
If necessary, contact Sauer-Service.
