Operating Your Air Compressor
Before starting the compressor,
thoroughly read all component
instruction manuals, especially
the engine manual.
NOTICE
Failure to install appropriate
water/oil removal equipment
may result in damage to
machinery or workpiece.
NOTICE
Drain liquid from tank daily.
NOTICE
Do not attach air tools to open
end of the hose until start-up is
completed and unit checks OK.
!
CAUTION
Moisture in Compressed Air
Moisture in compressed air will form into
droplets as it comes from an air compres-
sor pump. When humidity is high or when
a compressor is in continuous use for an
extended period of time, this moisture will
collect in the tank. When using a paint
spray or sandblast gun, this water will be
carried from the tank through the hose,
and out of the gun as droplets mixed with
the spray material.
IMPORTANT: This condensation will
cause water spots in a paint job, especial-
ly when spraying other than water based
paints. If sandblasting, it will cause the
sand to cake and clog the gun, rendering
it ineffective.
A filter in the air line, located as near to the
gun as possible, will help eliminate this
moisture.
Remove the dipstick/ breather and fill
pump with 12 ounces of oil. Use single vis-
cosity, ISO 100 (SAE 30), non-detergent
compressor oil; or Mobil 1
®
5W30 or
10W30 synthetic oil may also be used.
Proper oil fill is illustrated in Figure 5.
