Operating Your Air Compressor

All lubricated compressor pumps dis- charge some condensed water and oil with the compressed air. Install appropri-

ate water/oil removal equipment and con- trols as necessary for the intended appli- cation.

Moisture in Compressed Air

Moisture in compressed air will form into droplets as it comes from an air com- pressor pump. When humidity is high or when a compressor is in continuous use for an extended period of time, this mois- ture 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, espe- cially 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.

Lubrication

NOTICE:

THIS UNIT CONTAINS NO OIL! Follow lubrication instructions before operating compressor.

Remove the dipstick and fill pump with 12 ounces of oil. Use single viscosity, ISO

100 (SAE 30), non-detergent compressor oil; or Mobil 1® 5W30 or 10W30 synthetic oil may also be used. See illustration for prop- er oil fill.
