GENERAL INFORMATION

You have purchased an air compressor unit consist- ing of a one cylinder, single-stage air compressor pump and air tank. Included are wheels, regulator, and gauges.

This air compressor requires no oil. Now you can enjoy all the benefits of having an air compressor without ever having to purchase, add or change oil.

Your air compressor can be used for operating paint spray guns, air tools, blow guns, nailers/staplers, air brushes, and inflator kits. An air pressure regulator is required for most of the applications.

An in-line air filter which removes moisture and dirt from compressed air should be used where applicable.

An in-line regulator can be used if a more precise adjustment of air pressure is needed downstream.

GLOSSARY

CFM: Cubic Feet per Minute.

SCFM: Standard Cubic Feet per Minute; a unit of measure of air delivery.

PSI: Pounds per Square Inch; a unit of measure of pressure.

ASME: American Society of Mechanical Engineers; made, tested, inspected and registered to meet the standards of the ASME.

Cut-In Pressure: While the motor is off, air tank pressure drops as you continue to use your acces- sory. When the tank pressure drops to a certain low level and the pressure switch lever is in "Auto", the motor will restart automatically. The low pressure at which the motor automatically restarts is called “cut- in pressure.”

Cut-Out Pressure: When you turn on your air com- pressor and it begins to run, air pressure in the air tank begins to build. It builds to a certain high pressure before the motor automatically shuts off - protecting your air tank from pressure higher than its capacity. The high pressure at which the motor shuts off is called “cut-out pressure.”

CSA: Electrical products sold in Canada are required to be certified to the applicable CSA standard (s). Canadian Standards Association (CSA) is a standards writing and safety testing organization. Products that are CSA certified have been evaluated and tested and found to meet or exceed the applicable CSA standard

(s) for safety and electrical performance.
