GLOSSARY

Become familiar with these terms before operating the unit.

CFM: Cubic feet per minute. SCFM: Standard cubic feet per minute; a unit of measure of air delivery. PSIG: Pounds per square inch gauge; a unit of measure of pressure. Code Certification: Products that bear one or more of the following marks:

UL, CUL, ETL, CETL, have been evaluated by OSHA certified independent safety laboratories and meet the applicable Underwriters Laboratories Standards for Safety. 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 a certain low level 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 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.

Branch Circuit: Circuit carrying electricity from electrical panel to outlet.

DUTY CYCLE

This air compressor pump is capable of running continuously. However, to prolong the life of your air compressor, it is recommended that a 50%-75% average duty cycle be maintained; that is, the air compressor pump should not run more than 30-45 minutes in any given hour.

To Add Oil To Pump

Risk of Unsafe Operation. DO NOT ATTEMPT TO

OPERATE THIS AIR COMPRESSOR WITHOUT FIRST ADDING OIL TO THE CRANKCASE. Serious damage can result from even limited operation unless filled with oil and broken in correctly. Make sure to closely follow initial start-up procedures.

Risk of Unsafe Operation. COMPRESSORS ARE SHIPPED

WITHOUT OIL. A small amount of oil may be present in the pump upon receipt of the air compressor. This is due to plant testing and does not mean the pump contains oil.

Risk of Unsafe Operation. Multi-Viscosity motor oils, like

10W 30, should not be used in an air compressor. They leave carbon deposits on critical components, thus reducing performance and compressor life. Use air compressor oil only.

NOTE: Use an air compressor oil such as SAE-30 (API CG/CD heavy duty

motor oil). Under extreme winter conditions use SAE-10 weight oil.

1. Place unit on a level surface.

Risk from Flying Object. Drain tank to release air pressure

before removing the dipstick. See "To Drain Tank" in Maintenance section.

Extension Cords

Using extension cords is not recommended. The use of extension cords will cause voltage to drop resulting in power loss to the motor and overheating.

Instead of using an extension cord, increase the working reach of the air hose by attaching another length of hose to its end. Attach additional lengths of hose as needed. If an extension cord must be used, be sure it is:

• a 3-wire extension cord that has a 3-blade grounding plug, and a 3-slot

receptacle that will accept the plug on the product

• in good condition

• no longer than 50 feet

• 12 gauge (AWG) or larger. (Wire size increases as gauge number

decreases. 10 AWG and 8 AWG may also be used. DO NOT USE 14 OR 16 AWG.)

Voltage and Circuit Protection

Refer to the specification chart for the voltage and minimum branch circuit requirements.

Certain air compressors can be operated on a 15 amp circuit if the following conditions are met.

1. Voltage supply through branch circuit is 15 amps.

2. Circuit is not used to supply any other electrical needs (lights, appliances,

etc.).

3. Extension cords comply with specifications.

4. Circuit is equipped with a 15 amp circuit breaker or 15 amp time delay

fuse. NOTE: If compressor is connected to a circuit protected by fuses, use only time delay fuses. Time delay fuses should be marked “D” in Canada and “T” in the US.

OPERATION

Know Your Air Compressor

READ THIS OWNER’S MANUAL AND SAFETY RULES BEFORE OPERATING YOUR UNIT. Compare the illustrations with your unit to familiarize yourself with the location of various controls and adjustments. Save this manual for future reference.

Description of Operation

Become familiar with these controls before operating the unit. On/Auto/Off Switch (A): Turn this

switch ON to provide automatic power to the pressure switch and OFF to remove power at the end of each use.

Pressure Switch (B): The pressure switch automatically starts the motor when the air tank pressure drops below the factory set “cut-in” pressure. It stops the motor when the air tank pressure reaches the factory set “cut-out” pressure.

Safety Valve (C): If the pressure switch does not shut off the air compressor at its “cut-out” pressure setting, the safety valve will protect against high pressure by “popping out” at its factory set pressure (slightly higher than the pressure switch “cut-out” setting).

Outlet Pressure Gauge(D):

The outlet pressure gauge indicates the air pressure available at the outlet side of the regulator. This pressure is controlled by the regulator and is always less than or equal to the tank pressure.

Tank Pressure Gauge(E): The tank pressure gauge indicates the reserve air pressure in the tank.

Regulator (F): Controls the air pressure shown on the outlet pressure gauge. Pull the knob out and turn clockwise to increase pressure and counterclockwise to decrease pressure. When the desired pressure is reached push knob in to lock in place.

Universal Quick-Connect Body (G): The universal quick-connect body accepts the three most popular styles of quick-connect plugs- Industrial, automotive (Tru-flate), and ARO. One hand push-to-connect operation makes connections simple and easy. The two quick connect bodies allow the use of two tools at the same time.

Remote Console (H): Permits remote air regulation and control closer to work area, includes two high-flow industrial/automotive style compatible quickconnects, outlet pressure gauge, and a high-flow regulator.

13- ENG

D28301

Drain Valve (I): The drain valve is located at the base of the air tank and is used to drain condensation at the end of each use.

Cooling System (not shown): This compressor contains an advanced design cooling system. At the heart of this cooling system is an engineered fan. It is perfectly normal for this fan to blow air over the pump head, cylinder sleeve, and crankcase. You know the cooling system is working when air is being expelled.

Air Compressor Pump (not shown): Compresses air into the air tank. Working air is not available until the compressor has raised the air tank pressure above that required at the air outlet.

Dipstick (J): Indicates the amount of oil in the pump, the + mark indicates full and the - mark indicates oil needs to be added. See Oil paragraphs in the Maintenance section for instructions. Motor Thermal Overload Protector (not shown): The motor has an automatic reset thermal overload protector. If the motor overheats for any reason, the overload protector will shut off the motor. The motor must be allowed to cool down before restarting. The compressor will automatically restart after the motor cools.

Air Intake Filter (K): This filter is designed to clean air coming into the pump. This filter must always be clean and ventilation openings free from obstructions. See "Maintenance".

Check Valve (L): When the air compressor is operating, the check valve is “open”, allowing compressed air to enter the air tank. When the air compressor reaches “cut-out” pressure, the check valve “closes”, allowing air pressure to remain inside the air tank.

Pressure Release Valve (M): The pressure release valve located on the side of the pressure switch, is designed to automatically release compressed air from the compressor head and the outlet tube when the air compressor reaches “cut-out” pressure or is shut off. The pressure release valve allows the motor to restart freely. When the motor stops running, air will be heard escaping from this valve for a few seconds. No air should be heard leaking when the motor is running, or continuous leaking after unit reaches “cut-out” pressure.

How to Use Your Unit

How to Stop:

1. Set the On/Auto/Off lever to “OFF”.

Before you store the air compressor, make sure you do the following:

1. Review the "Maintenance" section on the preceding pages and perform

scheduled maintenance as necessary.

2. Set the On/Auto/Off lever to "OFF" and unplug unit.

3. Risk of Flying Objects. Pull the regulator knob out and

turn counter-clockwise to set the outlet pressure to

zero when removing hose or accessories to prevent hose backlash.

4. Remove the air tool or accessory.

5. Pull ring on safety valve allowing air to bleed from the tank until tank

pressure is approximately 20 psi. Release safety valve ring.

6. Drain water from air tank by opening drain valve on bottom of tank.

Risk of Bursting. Water will condense in the air tank. If not drained, water will corrode and weaken the air tank

causing a risk of air tank rupture.

7. After the water has been drained, close the drain or drain valve. NOTE: If drain valve is plugged, release

all air pressure. The valve can then be removed, cleaned, then reinstalled.

8. Wrap electrical cord onto the cord

wrap as shown.

9. Protect the air hose from damage

(such as being stepped on or run over).

10. Push pulling handle into place for storage.

11. Store the air compressor in a clean and dry location. IMPORTANT: Only use pulling handle to pull unit, use the carrying handle to lift

and carry unit.

TROUBLESHOOTING

PROBLEM

CAUSE

CORRECTION

Pressure switch does not shut off motor when compressor reaches “cutout” pressure.

Pressure switch “cut-out” too high.

Move On/Auto/Off lever to the “OFF” position, if the outfit does not shut off contact a Trained Service Technician. Contact a Trained Service Technician.

Excessive tank pressure safety valve pops off.

Tube fittings are not tight enough.

Tighten fittings where air can be heard escaping. Check fittings with soapy water solution. DO NOT OVERTIGHTEN.

Air leaks at fittings.

Air leaks at pressure switch release valve. (if equipped)

Defective pressure switch release valve.

Contact a Trained Service Technician.

Air leaks in air tank or at air tank welds.

Defective air tank.

Air tank must be replaced. Do not repair the leak.

Risk of

Bursting. Do not drill into, weld or otherwise modify air tank or it will weaken. The tank can rupture or explode.

Air leaks between head and valve plate.

Leaking seal.

Contact a Trained Service Technician.

Air leaks at or inside check valve

Check valve seat damaged.

A defective check valve results in a constant air leak at the pressure release valve when there is pressure in the tank and the compressor is shut off. Replace check valve. Refer the “To Replace or Clean Check Valve” in the “Service and Adjustment” section.

Risk of Unsafe Operation. Unit cycles automatically when

PROBLEM

CAUSE

CORRECTION

Compressor is not supplying enough air to operate accessories.

Prolonged excessive use of air. Compressor is not large enough for air requirement.

Hole in hose.

Check valve restricted.

Air leaks.

Restricted air intake filter

Decrease amount of air usage.

Check the accessory air requirement. If it is higher than the SCFM or pressure supplied by your air compressor, you need a larger compressor. Check and replace if required.

Remove and clean, or replace.

Tighten fittings.

Clean or replace air intake filter. Do not operate the air compressor with the filter removed. Refer to the “Air Filter” paragraph in the “Maintenance “ section.

Pressure reading on the regulated pressure gauge (if equipped) drops when an accessory is used.

It is normal for “some” pressure drop to occur.

If there is an excessive amount of pressure drop when the accessory is used, adjust the regulator as instructed in the Operation section. NOTE: Adjust the regulated pressure under flow conditions (while accessory is being used).

Possible defect in safety valve.

Operate safety valve manually by pulling on ring. If valve still leaks, it should be replaced.

Air leak from safety valve.

Clean or replace. See Air Filter paragraph in the Maintenance section.

Dirty air filter.

Restricted air intake

Damaged regulator Have checked by a Trained

Service Technician.

Regulator knob has continuous air leak.

Regulator will not shut off air outlet.

Damaged regulator Have checked by a Trained

Service Technician.

PROBLEM

CAUSE

CORRECTION

Motor will not run.

Fuse blown, circuit breaker tripped.

1. 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 your particular branch circuit.

2. Check for proper fuse. You should use a time delay fuse.

3. Check for low voltage conditions and/or proper extension cord.

4. Disconnect the other electrical appliances from circuit or operate the compressor on its own branch circuit.

Motor overload protection switch has tripped

Let motor cool off and overload switch will automatically reset.

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

Motor will start automatically when tank pressure drops below “cut-in” pressure of pressure switch.

Loose electrical connections.

Check wiring connection inside pressure switch and terminal box area.

Have checked by a Trained Service Technician.

Check valve stuck open.

Remove and clean, or replace.

Possible defective motor or starting capacitor.

Have checked by a Trained Service Technician. Do not operate the compressor in the paint spray area. See flammable vapor warning.

Paint spray on internal motor parts.

Bleed the line by pushing the lever on the pressure switch to the “off” position; if the valve does not open, replace switch.

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