LONG TERM STORAGE RECOMMENDATIONS
(6 months or more)
Spare Airends
•
Long--term storage of airends should include filling the airend with
the standard compressor fluid, PRO--TEC, XHP605 or XHP405.
Upon installation of the airend, drain the storage oil from the airend
and proceedwith the installation, assuring fresh oil is poured into the
intake prior to start up.
Portable Compressors
•
Airend -- Remove the intake connection and pour the airend intake
full with Doosan compressor fluid PRO--TEC, XHP605 or XHP405.
Reconnect the intake connection.
•
Engine cooling system -- Treat with rust inhibitor and drain. Check
with engine dealer for further recommendations.
•
Compressor Oil Filter/s-- fill with Doosan compressor fluid PRO--
TEC, XHP605 or XHP405.
•
Seal all opening with waterproof tape.
•
Place a desiccant in the exhaust pipes, engine and compressor air
intake pipes.
•
Loosen tension on belts, fan, airend, etc.
•
Block axles so tyres are off ground and do not support any weight.
•
Disconnect battery cables.
•
Drain fuel system.
SHORT TERM STORAGE
Machines that stand idle for extended periods of timegreater than
30 days:
•
Start and operate the machine every 30 days. Operate long enough
to allow the engine and compressor to reach operating
temperature.
•
Open and close the service valve to exercise machine fromfull load
to idle RPM.
•
Drain fuel tank to remove any water.
•
Drain water from fuel water separator.
NOTE:
If the machine has been operating under adverse conditions,
or has suffered long shutdown periods, then more frequent service
intervals will be required.
WARNING:
DO NOT
, under any circumstances, remove any
drain plugs or the oil filler plug from the compressor lubricating
and cooling system without first making sure that the machine
is stopped and the system has been completely relieved of all air
pressure (refer to
STOPPING THE UNIT
in the
OPERATING IN-
STRUCTIONS
section of this manual).
NOTE:
If the oil is drained immediately after the machine has been
running, then most of the sediment will be in suspension and will
therefore drain more readily.
CAUTION:
Some oil mixtures are incompatible and result in the
formation of varnishes, shellacs or lacquers which may be insoluble.
NOTE:
Always specify PRO-TEC oil for use at all ambient
temperatures above -23°C.
