CAUTION: ALWAYS DISCONNECT THE POWER
SYSTEM BEFORE ATTEMPTING TO SERVICE THE
AIR COMPRESSOR OR ANY COMPONENT UTILIZED
IN THE SYSTEM. If the power disconnect is out-of-
sight, lock It In the open position and tag to prevent
unexpected application of power.
Periodic inspection of the air compressor should be a
mandatory part of normal in-plant inspection tours of
your system. Occasionally it will be necessary to
replace worn or damaged parts. Damaged or worn parts
are a potential threat to personal safety and property;
under no circumstances should damaged or worn parts
If compressor fails to pump air or seems slow in filling,
remove valves and seats and clean thoroughly. After
cleaning; exceptional care must be taken to replace al
parts in exactly the same positions. All joints must be
tight or the compressor will not function properly. When
valves are replaced and connections tight, unit should fill
to 80 PSI within 10 minutes (discharge line shut off).
As with all systems, it may become necessary clean them
periodically to keep them in peak operating condition. Any
cleaning methods used should be suitable with the air
compressor and components which make up the system.
NEVER ALLOW OIL LEVEL TO FALL MORE THAN 1/8"
BELOW THE FULL LEVEL. The type of oil user depends
on operating conditions and surrounding temperature at the
point of installation. For proper oil viscosity, refer to the
chart under Operation page 5.
OIL CHANGE: Check oil level daily. In normal or
intermittent duty installations where unit does not operate
extensively, change oil every 200 hours or 60 days,
whichever occurs first. Under extensive, or continuous
operation, or where hot humid, or dusty/dirty conditions
exist, oil change interval should be sharply reduced to 100
hours or 30 days (or less), whichever occurs first.
