SECTION 8
MAINTENANCE SCHEDULE
SERVICE CHECK LIST –
Air Filter – Operating conditions determine frequency
of service. The “CHANGE AIR FILTER” LED will illumi-
nate to signal that the air filter requires servicing or
changing. See “Air Filter,” Section 6, page 45.
Water Filter – Operating conditions and water quality
determine the frequency of service. The “CHG WATER
FILTER” LED will illuminate to signal that the water filter
requires changing. See “Changing the Injection Water
Filter,” Section 2, page 16.
Motor Lubrication – Refer to Section 2, page 17, and
Maintenance Schedule Chart below.
Every 8 Hours Operation
1.
Observe if the unit loads and unloads properly.
2.
Check discharge pressure and temperature.
3.
Drain the petcock on the inlet valve control line.
4.
Check Panel LED’s for advisories.
Every 125 Hours Operation
1.
Check for dirt accumulation on oil/aftercooler core
faces and the cooling fan. If cleaning is required,
clean the exterior fin surfaces of the cores by
blowing compressed air carrying a nonflammable
safety solvent in a direction opposite that of the
cooling fan air flow. This cleaning operation will
keep the exterior cooling surfaces clean and en-
sure effective heat dissipation.
2.
Check the reservoir oil level – add oil if required.
Loss of oil will be because of seal failure or leaks
in the system and should be fixed immediately.
Every 8000 Hours Operation
1.
Change the compressor lubricant. UNDER AD-
VERSE CONDITIONS, CHANGE MORE FRE-
QUENTLY (refer to “Oil Change Interval”, page
41). Flush system if required. DO NOT MIX LU-
BRICANTS.
2.
Change the oil filter element. Change whenever
the oil is changed.
Every Year
1.
Check the relief valve for proper operation. See
Section 4, page 30.
2.
Check minimum pressure/check valve seals.
