• Save alt instructions

AWRNING

Improper operation or m.aintenance of this product could result in serious injury and/or property damage. Read and understand all of the warnings and safety instructions provided before using this equipment.

			The air compressor should be operated on a dedicated 15 amp circuit. If the circuit
			does not have 15 free amps available, a larger circuit must be used. Always use
	t^MITION		more air hose before utilizing extension cords. All extension cords used must be 12
			gauge with a maximum length of 25 ft. The circuit fuse type must be a time delay. Low
			voltaae could cause damaoe to the motor.
Risk of Moving Parts			If the air compressor is in operation, all guards and covers should be attached or
			installed correctly, if any guard or cover has been damaged, do not operate the
			equipment until the proper personnel has correctly repaired the equipment. The power
			cord should be tree of any moving parts, twisting and./or crimping while in use and
			while in storage.

Risk of Burns

Risk of Falling

Risk from Flying Objects

There are surfaces on your air compressor that while in operation and thereafter can cause serious burns if touched. The equipment should be allowed time to cool before any maintenance is attempted. Items such as the compressor pump and the outlet tube are normally hot during and after operation.

Operation of the air compressor should always be in a position that is stable. Never use the air compressor on a rooftop or elevated position that could allow the unit to fall or be tipped over. Use additional air hose for elevated jobs.

Always wear ANSI Z87.1 approved safety glasses with side shields when the air compressor is in use. Turn off the air compressor and drain the air tank before performing any type of maintenance or disassembly of the hoses or fittings. Never point any nozzle or sprayer toward any part of the body or at other people or animals.

Lnp-ortani Safety Inst-uctíons S¡ Guidelines

Risk of Breathing

Risk of

Eiectrical Shock

Risk of Explosion or Fire

Risk of Bursting

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 doss 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,

Never utilize the air compressor in the rain or wet conditions. Any electrical issues or 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 groundirig plug, correct voltage, and adequate fuse protection.

Never operate the compressor near combustible materials, gasoline or solvent vapors. 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.

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 (I) (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 wCen 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 Undenvriters 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. ■

Parts & Features

See figures below tor reference.

Air Intake Filter

Provides dean air to the pump and must always be kept free ot debris. Check on a daily basis or before each use,

Regulator Gauge

Indicates the outgoing air pressure to the tool and is controlied by the regulator.

Tank Pressure Gauge

Indicates the reserve air pressure in the tank.

Pressure Switch

This controls the power to the motor and also the cut-in/cut-out pressure settings, This switch serves as the Auto-On/Off positions for the unit.

Pressure Relief Valve

The pressure relief valve, located on the side of the pressure switch, is designed to automatically release compressed air when the air compressor reaches cuPout pressure. The released air should only escape momentarily and the valve should then close.

Tank Drain Valve

Used to drain condensation from the air tank, Located at bottom of tank.

Tank Safety Valve

Used to allow excess tank pressure to escape into the.atmosphere. This valve should only open when the tank pressure is above the maximum rated pressure.

Regulator

The air pressure coming from the air tank is controlled by the regulator. To increase the pressure, turn the knob clockwise and to decrease the pressure turn the knob counterclockwise.

Quick Connect

Offers a quick release feature for attaching and removing the air hose.

Check Valve

When the pump is not in operation, the valve closes to retain air pressure inside the tank. An interna! component.
