LUBRICATING OIL SPECIFICATION
(for the specified ambient temperatures).
ABOVE -23°C(-9°F)
Recommended: PRO-TEC
Approved: SAE 10W, API CF-4/CG-4
PRO-TEC compressor fluid is factory-fitted, for use at all ambient
temperatures above -23°C (-9°F).
NOTE: Warranty may be extended only by continuous use of
PRO-TEC and Doosan oil filters and separators.
No other oil/fluids are compatible with PRO-TEC.
No other oils/fluids should be mixed with PRO-TEC because the
resulting mixture could cause damage to the airend.
In the event that PRO-TEC is not available and / or the end user
needs to use an approved single grade engine oil, the complete
system including separator / receiver, cooler and pipework must be
flushed clear of the first fill fluid and new Doosan oil filters installed.
When this has been completed, the following oils are approved:
for ambient temperatures above -23°C (-9°F),
SAE 10W, API CF-4/CG-4
Safety data sheets can be obtained on request from your Doosan
dealership.
For temperatures outside the specified ambient range, consult the
company.
