Compressor Oil Flushing Procedure - Atlas Copco XAS 400 JD IT4 HOP Instruction Manual

COMPRESSOR OIL FLUSHING
PROCEDURE
Not respecting compressor oil changing
intervals in accordance with the maintenance
schedule, can lead to serious problems,
including fire hazard! The manufacturer does
not accept any liability for damage arising
from not following the maintenance schedule
or not using genuine parts.
To avoid problems when changing over to a new type of
oil (see table) a special Compressor Oil Flushing
Procedure has to be followed. The table is only valid when
the replaced oil has not exceeded its lifetime. For more
information consult Atlas Copco Service dept.
Aged oil can be recognized best by using an oil sampling
analysis program. Indicators for aged oil are strong smell,
or contamination such as sludge and varnish inside the oil
vessel and oil stop valve or a brownish colour of the oil.
Whenever aged oil is discovered, eg. when changing the
oil separator, contact Atlas Copco Service dept. to have
your compressor cleaned and flushed.
1. First thoroughly drain the system when the oil is warm,
leaving as little oil in the system as possible, especially
in dead areas, if possible blow out remaining oil by
pressurising the oil system. Check the instruction
manual for detailed description.
2. Remove the compressor oil filter(s).
3. Open the oil vessel and remove the oil separator ele-
ment.
Instructions on replacing the oil separator
element are available from Atlas Copco
Service dept.
4. Check the interior of the oil vessel (see pictures). If
varnish deposits are discovered, contact Atlas Copco
Service dept. and do not continue.
5. Put in a new oil separator, screw on new compressor
oil filter(s) and close the oil vessel according to the
instructions.
6. Fill the oil vessel with the minimum amount of
replacement oil, run the compressor under light load
conditions for 30 minutes.
7. Thoroughly drain the system when the oil is warm,
leaving as little oil in the system as possible, espe-
cially in dead areas, if possible blow out remaining
oil by pressurising the oil.
8. Fill the system with the final oil charge.
9. Run the compressor under light load conditions for
15 minutes and check for leakage.
10. Check the oil level and top up if necessary.
11. Collect all waste lubricant used during the flushing
process and dispose of it in accordance with the
applicable procedures for managing waste lubricant.
