9.2 Temporary preservation & storage
If idle, every 4 weeks perform a test run for at least 30 minutes.
Additional corrosion prevention measures are not required.
When the Sauer compressor is to be layed-up for more than 12
weeks, preservation with a flushing or preservation oil is recom-
mended. When this preservation is completed, periodic test runs
are not needed.
1. Run compressor for approx. 5 minutes with drain valves and
final pressure line open.
Any existing oil / water is removed.
2. Drain compressor oil for safe disposal.
Close oil drain plug.
3. Fill with about 1 litre of preservation oil.
4. Start compressor and run for approx. 5 minutes with drain
valves and final pressure line open.
5. Stop compressor.
6. Unscrew the air intake filter on the cylinder head of the 1
st
sta-
ge, for this purpose, loosen the clamp and remove the air fil-
ter.
7. Unscrew the safety valve of the 1
st
stage on the cylinder head
of the 2
nd
stage.
8. Start compressor and slowly inject 15 cm
3
preservation oil in
the air intake port of the 1
st
stage.
Note!
Use one of the preservation oils recommended in Chapter 10
"Lubricant Table" for corrosion protection.
The preservation oil has satisfactory running properties. In an
emergency the machine can be started for a short duration when
filled with preservation oil.
