MAINTENANCE SCHEDULE
SERVICE CHECK LIST --
Air Filter -- Operating conditions determine frequency
of service. See “Air Filter,” Section 6, page 35.
Motor Lubrication -- Refer to Section 2, page 9, and
Maintenance Schedule Chart below.
Every 8 Hours Operation
1. Check the reservoir oil level -- add oil if required.
See Section 5, page 28. If oil consumption is high,
refer to “Excessive Oil Consumption,” page 42.
2. Observe if the unit loads and unloads properly.
3. Check discharge pressure and temperature.
Every 125 Hours Operation
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 com-
pressed 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 sur-
faces clean and ensure effective heat dissipation.
Every 150 Hours Operation
Check/change the air filter.
Every 1000 Hours Operation
Change oil filter element.
Every 4000 Hours Operation
Change the compressor lubricant. UNDER ADVERSE
CONDITIONS, CHANGE MORE FREQUENTLY (re-
fer to “Oil Change Interval”, Section 5, page 29). Flush
system if required.
Every Year
1. Check the relief valve for proper operation. See
Section 4, page 19.
2. Change oil separator, see “Compressor Oil Sepa-
rator,” page 33, for further details (or 8 psid pres-
sure differential across the element).
