Compressor Maintenance
Warning: To avoid personal injury, always shut OFF the main power supply and
disconnects to the compressor, relive all air pressure from the system, and check
electrical system with electrical probe before starting any service or maintenance
on the compressor.
Daily:
Drain the Receiver- condensation will accumulate in
the tank daily, and should be drained at least once a
day. This is done to reduce corrosions of the tank from
the inside. Always wear protective eye wear when
draining the tank.
Check Pump Oil Level- All units have a sight glass the
oil level non running units should be no lower than ½
way on the sight glass if it is lower then you need to
add oil until it is at least ½ way up the sight glass.
Check unit for any unusual noise or vibrations.
Weekly:
Clean air filter: this will ensure that no dirt or heavy
particulate makes its way into the compressors valve
assemblies.
Clean external parts of compressor and electric motor:
this helps to ensure proper cooling and prevents rust
and corrosion on critical parts.
Check safety Valves: this is don’t to ensure they are not
stuck in place and operating properly.
Elite Units Check auto tank drain for proper function
Monthly:
Inspect complete air system for leaks: this is done to
make sure the compressor does not get out of its duty
cycle due to air leak in the system.
Inspect Oil for Contamination: this is done to ensure
that harmful deposits do not build up in the oil.
Check belt tension: this is done to ensure the belt
do not fail pre-maturely, tighten them as needed to
ensure they do not slip. If belts are loose, tighten per
instructions on next page. Failure to tighten can cause
pre-mature belt failure.
Every 3 months or 500 hrs (whichever comes first):
Change Oil: this is done to ensure that the compres-
sor has proper oil level and that the oil in the machine
does not deteriorate past factory specifications.
Inspect Valve assemblies: this is done to prevent pre-
mature failure and clean out and carbon that can form
in older valves.
*Elite Units. Clean auto tank drain strainer and check
for proper function.
Inspect pressure switch for proper function.
Inspect check valve for proper function and remove
any carbon accumulation to prevent premature failure.
*Clean belt guard coolers (if equipped).
Storage of Compressor:
Before storing the compressor for a prolonged period
of time, use a blow gun to clean all debris from com-
pressor. Shut OFF main power and turn OFF discon-
nect. Drain tank pressure, clean air filter, drain old oil
and replace with new oil. Cover the unit to prevent
dust and moisture from collecting on the unit.
NOTE: Maintaining proper oil level and performing oil
changes at proper intervals is necessary for the proper
function of the air compressor system. The best oil for you
air compressor is CAS30100 full synthetic reciprocating
compressor oil.
Your average vehicle travels 30,000 highway mikes in 500
hrs or 15,000 city miles in 500 hrs at 210ºF or less.
In the same 500 hrs/3 months a reciprocating compres-
sors operating temperature may exceed 350ºF.
