9. MAINTENANCE [How to Service the Air Compressor]

■
Check the condensate drain
Moisture in the intake air, especially in hot and humid environments, is condensed inside the air compressor during
compression. Daily inspect intercooler/aftercooler condensate drain to verify that there is a discharge of
compressed air (with condensate) when the air compressor is loaded. Bi-annually, clean the strainer element and
annually clean the orifice for both intercooler/aftercooler.
■
Cleaning of strainer element
The strainers for both the intercooler and
aftercooler shall be cleaned.
①
Discharge the compressed air in the procedure
in
9.4

.
②
Remove the cover of the strainer.
③
Remove the element, wash with water and blow
air.
④
Remove the element from inside the strainer and
wash with water.
⑤
Replace the cleaned element in its original
position and set the gasket, and plug properly.
■
Cleaning of orifice
Inspect and clean the orifices annually. Be sure to
stop the air compressor before inspecting and/or
cleaning the orifices.
■
Replacement of the strainer and solenoid
valve
Replace the solenoid valve and the strainer every 2
years (if operating 8000 hours/year) or 3 years (if
operating 4000 hours/ year) to new whole
assembled parts.

Cleaning of orifice
●
Verify that discharged air with condensate
is discharged through the drain ports of
intercooler and aftercooler every 20
seconds during loading.
●
If compressed air is not discharged, clean
and unclog the drain port (filter & orifice).
●
Operating the air compressor without
d r a i n i n g t h e c o n d e n s a t e f r o m t h e
intercooler/afterooler, may rust the airend
internally and cause a major failure.
