6. Contact a trained service technician.

Knocking noise

Safety valve dirty or defective. Operate safety valve manually by pulling on

ring. If valve still leaks, have it replaced.

TROUBLESHOOTING

PROBLEM CAUSE CORRECTION

Compressor is not supplying enough air to operate accessories.

1. Prolonged excessive use of air.

2. Compressor is not large enough for air requirement.

3. Hole in hose.

4. Check valve restricted or leaks air.

5. Restricted air intake filter.

1. Decrease amount of air used.

2. Check the accessory requirement. If it is higher than the CFM or pressure supplied by your air compressor, you need a larger capacity air compressor.

3. Check and replace if required.

4. Remove and clean or replace check valve.

5. Tighten fittings. Clean or replace air intake filter (see page 13).

Motor will not run.

1. Motor overload protection switch has tripped.

2. Tank pressure exceeds pressure switch “cut-in” pressure.

3. Loose electrical connections.

4. Possible defective motor or starting capacitor.

5. Pressure release valve on pressure switch has not unloaded head pressure.

6. Fuse blown, circuit breaker tripped.

1. Let motor cool for 15 minutes. Press RESET to reset overload switch.

2. Motor will start automatically when tank pressure drops below “cut-in” pressure setting.

3. Check wiring connection inside pressure switch and terminal box area.

4. Have checked by a trained service technician.

5. Drain pressure by setting ON/AUTO - OFF switch to OFF. If the valve does not open, replace pressure switch.

6A. Check fuse box for blown fuse and replace as

necessary. Reset circuit breaker. DO NOT use a fuse or circuit breaker with higher rating than that specified for that branch circuit.

B. Check for proper fuse. Use a time delay fuse. C. Check for low voltage conditions and/or

proper extension cord.

D. Disconnect all other electrical loads from

circuit used by air compressor OR operate air compressor on dedicated branch circuit.

GLOSSARY

Becoming familiar with these terms will help you understand and operate most air compressors:

Air Delivery – A combination of psi and CFM.The air delivery required by a tool or accessory is stated as “’number’ (S)CFM at ‘number’ psi”. For example “5.1 CFM at 90 psi”.The combination of these values dictates the required air compressor capacity.

Air Tank Capacity – The volume of air stored in the tank and available for immediate use.

Alternating Current (AC) - Voltage that increases to a maximum positive value (+) and falls back to zero and then continues to a maximum negative value (-) and back to zero. This cycle is repeated 60 times each second for 60 hertz AC power.

ASME Certified - Indicates that the pressure vessel (air tank) and related components are manufactured, tested, and inspected to the specifications set by the American Society of Mechanical Engineers.

ASME Safety Valve - A protection device that automatically releases tank air if the air contained within exceeds a preset maximum rating.

Cast Iron Sleeve - A thin iron cylinder cast into the cylinder head, producing a harder surface between the aluminum cylinder walls and steel piston rings, thus extending the life of the compressor.

CFM or SCFM (Standard Cubic Feet per Minute). SCFM is the volume of air, in cubic feet, that the compressor can pump in one minute at a specific working pressure.The term CFM is used in this manual.

Circuit Breaker - A thermal switch that opens a circuit if too much current is passing through it.The air compressor motor is protected by this resettable device.

Cut-In Pressure – As air is taken from the air tank, the tank air pressure drops.At a certain low level, the pressure switch senses this low pressure and turns-on the compressor motor, thus refilling the air tank.The level at which the motor switches ON is called the Cut-In Pressure.

Cut-Out Pressure – While the compressor is running, air is being produced and stored in the air tank. If no air is being used, air pressure will build in the tank.The pressure switch senses this high pressure and at a certain high level, it turns the compressor motor off.The level at which the motor switches OFF is called the Cut-Out Pressure.

Duplex Receptacle - Two 120 volt AC receptacles that are tied together. Similar to common household outlets.

GFCI - Ground fault current interrupter.A device that will sense current flow in the milliamp range in a power circuit to ground conductor and activate a relay to open both line conductors.

Ground - A connection, either intentional or accidental, between an electric circuit and the earth or some conducting body serving in place of the earth.

Pressure Control – Often called a regulator, this device is used to adjust the air compressor’s pressure output.The Pressure Control is adjusted to supply the psi value required by certain air tools, as monitored on the Regulated Pressure Gauge.

psi - pounds per square inch.The measure of air pressure delivered by the air compressor system.

Single Stage - Single stage refers to an air compressor with one or more cylinders that take air in each cylinder at the down stroke and compresses the air into the air tank on the up stroke.

Tank Pressure Gauge – A device used to indicate the air pressure contained in the air tank, in psi

Two Stage - A two-stage compressor always has a minimum of two cylinders - a low pressure (LP) cylinder (largest) and an high pressure (HP) cylinder (smallest).As the LP piston goes downward, air is taken in at atmospheric pressure;on the upward stroke the LP piston discharges the air through an intercooler and into the HP cylinder on its downward stroke. On the upward stroke of the HP piston the air is discharged into the air tank.Two-stage compressors are recommended when tool usage is continuous.

Vibration Isolators – When installed, are designed to minimize vibrations produced by the air compressor.
