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

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.

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.

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.

Drain tank to release air pressure before removing the

dipstick.

Make sure air vent (B) in

dipstick is free from

debris. If air vent is blocked pressure

can build in crankcase causing damage

to air compressor and possible personal

injury.

2. Remove dipstick (A) and slowly fill

crankcase with oil. Crankcase

capacity is 8 fluid ounces (236.6 ml).

Oil level should be at the + (full) mark

on the dipstick.

NOTE: If the oil is added too quickly, it will

overflow and appear to be full.

3. Replace dipstick.

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.

If any of the above conditions cannot be met, or if operation of the compressor

repeatedly causes interruption of the power, it may be necessary to operate it

from a 20 amp circuit. It is not necessary to change the cord set.

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 quick-

connects, outlet pressure gauge, and a high-flow regulator.

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.

Air Filter - Inspection and Replacement

Hot surfaces. Risk of burn. Compressor heads are

exposed when filter cover is removed. Allow compressor

to cool prior to servicing.

A dirty air filter will not allow the compressor to operate at full capacity. Keep

the air filter clean at all times.

1. Remove the air filter cover.

2. Remove the air filter from filter cover.

IMPORTANT: Do not operate the compressor with the air filter removed.

3. Place new air filter into filter cover. Refer to the “Repair Parts” for the

correct part number.

4. Replace air filter cover and lock into place.

5. Slowly fill crankcase with oil. Crankcase capacity is 8 fluid ounces (236.6

ml). Oil level should be at the + (full) mark on the dipstick.

Overfilling with oil will cause premature compressor

failure. Do not overfill.

6. Replace dipstick (A).

Motor

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.

If the overload protector shuts the motor off frequently, check for a possible

voltage problem. Low voltage can also be suspected when:

1. The motor does not get up to full power or speed.

2. Fuses blow out when starting the motor; lights dim and remain dim when

motor is started and is running.

STORAGE

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".

3. Turn the regulator counterclockwise and set the outlet pressure to zero.

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.

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. Store the air compressor in a clean and

dry location.
