Important Safety Instructions & Guidelines

Risk of Breathing		Avoid using the air compressor in confined areas. Always have adequate space
		(12 inches) on all sides of the air compressor. Also keep children, pets, and others out of
		the area of operation. This air compressor does not provide breathable air for anyone or
		any auxiliary breathing device. Spraying material will always need to be in another area
		away from the air compressor to not allow intake air to damage the air compressor filter.
	Risk of	Never utilize the air compressor in the rain or wet conditions. Any electrical issues or
Electrical Shock		repairs should be performed by authorized personnel such as an electrician and should
		comply with all national and local electrical codes. The air compressor should also have
		the proper three prong grounding plug, correct voltage, and adequate fuse protection.

	Risk of	Never operate the compressor near combustible materials, gasoline or solvent vapors.
Explosion or Fire		If spraying flammable materials, locate the air compressor at least 20 feet away from the
		spray area. Never operate the air compressor indoors or in a confined area.

Risk of Bursting	Always drain the air compressor tank daily or after each use. If the tank develops a leak,
	then replace the air compressor. Never use the air compressor after a leak has been
	found or try to make any modifications to the tank. Never modify the air compressor’s
	factory settings which control the tank pressure or any other function.

Glossary

CFM: Cubic feet per minute.

SCFM: Standard cubic feet per minute; a unit of measure for air delivery.

PSIG: Pounds per square inch gauge; a unit of measure for pressure.

ASME: American Society of Mechanical Engineers.

California Code: Unit may comply with California Code 462 (l) (2)/ (M) (2).

Cut-In Pressure: The air compressor will automatically start to refill the tank when the pressure drops below the prescribed minimum.

Cut-Out Pressure: The point at which the motor stops when the tank has reached maximum air pressure.

Code Certification: Products that bear one or more of the following marks: UL, ULc, ETL, CSA, have been evaluated by OSHA-certified independent safety laboratories and meet the applicable Underwriters Laboratories Standards for Safety.

Duty Cycle

This is a 50% duty cycle air compressor. Do not run the air compressor more than 30 minutes of one hour. Doing so could damage the air compressor.
