WARNING:
RISK OF FIRE.
RISK TO BREATHING.
RISK OF INJURY
RISK TO HEARING.
NOTE: ELECTRICAL WIRING.
CAUTION:
Drain the moisture from the tank on a daily basis. A clean, dry tank will help prevent corrosion.
Pull the tank safety valve ring daily to ensure that the valve is functioning properly, and to clear the valve of any possible obstructions.
To provide proper ventilation for cooling, the compressor must be kept a minimum of 12 inches (31 cm) from the nearest wall, in a
well–ventilated area. Restricting any of the compressor ventilation openings will cause overheating and could cause fire, never place
objects against or on top of compressor.
Fasten the compressor down securely if transporting is necessary. Pressure must be released from the tank before transporting.
Protect the air hose and interconnect cord from damage and puncture. Inspect them weekly for weak or worn spots, and replace if
necessary.
To reduce the risk of electric shock, do not expose to rain. Store indoors.
On oil-lubed compressors, oil can leak or spill and could result in fire or breathing hazard. Oil leaks will damage paint, carpet or other
surfaces in vehicles or trailers. Always place the compressor on a protective mat when transporting to protect against damage to
vehicle from leaks. Remove compressor from vehicle immediately upon approval at your destination.
To prevent damage to tank and compressor on stationary models, the tank must be shimmed so the pump base is level within 1/8" to
distribute oil properly. All feet must be supported, shimming where necessary, prior to attaching to the floor. Fasten all feet to floor. We
also recommend the use of vibration pads (094-0137) under tank feet.
CFM: Cubic feet per minute; a unit of measure of air flow.
PSI: Pounds per square inch; a unit of measure of air pressure.
Cut-in pressure: While the motor is off, air tank pressure drops
as you continue to use your accessory. When the tank pressure
drops to factory set low pressure point, the motor will restart
automatically. The low pressure at which the motor automatically
restarts is called "cut-in" pressure.
Cut-out pressure: When an air compressor is turned on and
begins to run, air pressure in the air tank begins to build. It builds
to the factory set high pressure point before the motor
automatically shuts off, protecting your air tank from pressure
higher than its capacity. The high pressure at which the motor
IMPORTANT SAFETY INSTRUCTIONS
Unattended operation of this compressor could result in personal injury or property damage. To
reduce the risk of fire, do not allow the compressor to operate unattended. Always disconnect
electrical power by turning the pressure switch to off and drain the tank daily or after each use.
Air obtained directly from the compressor should never be used to supply air for human
consumption. The air stream may contain carbon monoxide, toxic vapors, or solid particles from
tank. Breathing these contaminant's can cause serious injury or death. In order to use air produced
by this compressor for breathing, suitable filters and in-line safety equipment must be properly
installed. In-line filters and safety equipment must be properly installed. In-line filters and safety
equipment used in conjunction with the compressor must be capable of treating air to all applicable
local and federal codes prior to human consumption.
Always operate the compressor in a stable secure position to prevent accidental movement of the
unit. Never operate the compressor on a table, workbench, roof or other elevated position. Use
additional air hose to reach high locations.
Always wear hearing protection when using an air compressor. Failure to do so may result in
hearing loss.
The interconnect cord on this product contains lead, a chemical known to the State of California to
cause cancer, and birth defects or other reproductive harm. Wash hands after handling.
Refer to the air compressor's serial label for the unit's voltage and amperage requirements. Ensure
that all wiring is done by a licensed electrician, in accordance with the National Electrical code.

shuts off is called "cut-out" pressure.
Well-ventilated: Means of providing fresh air in exchange for
dangerous exhaust or vapors.
