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

Air compressors should be operated on not more than a 50% duty cycle. This means an air compressor that pumps air more than 50% of one hour is considered misuse, because the air compressor is undersized for the required air demand. Maximum compressor pumping time per hour is 30 minutes.

Accessories for this unit are available at the store the unit was purchased.

GROUNDING INSTRUCTIONS

RISK OF ELECTRICAL SHOCK. In the event of a short

circuit, grounding reduces the risk of shock by providing an escape wire for the electric current. This air compressor must be properly grounded.

The portable air compressor is equipped with a cord having a grounding wire with an appropriate grounding plug (see illustrations). The plug must be used with an outlet that has been installed and grounded in accordance with all local codes and ordinances.

1. The cord set and plug with this unit contains a

grounding pin. This plug MUST be used with a grounded outlet.

IMPORTANT: The outlet being used must be installed and grounded in accordance with all local codes and ordinances.

2. Make sure the outlet being used has the same

configuration as the grounded plug. DO NOT

USE AN ADAPTER.

When used outside of the United States of America a conversion kit may be required for

local use.

3. Inspect the plug and cord before each use. Do not use if there are signs of damage.

4. If these grounding instructions are not completely understood, or if in doubt as to whether the compressor is properly grounded, have the installation checked by a qualified electrician.

IMPROPER GROUNDING CAN RESULT IN ELECTRICAL SHOCK.

Do not modify the plug provided. If it does not fit the available outlet, a correct outlet should be installed by a qualified electrician.

Repairs to the cord set or plug MUST be made by a qualified electrician.

Grounding

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

• 14 gauge (AWG) or larger. (Wire size increases as gauge number decreases. 12 AWG, 10 AWG, and 8 AWG may also be used. DO NOT USE 16 OR 18 AWG.)

11- ENG

D27449

Voltage and Circuit Protection

Refer to the Parts Manual 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 marked “D” for Canada and "T" for 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: 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: 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: 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: 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: The tank pressure gauge indicates the reserve air pressure in the tank.

Regulator: 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.

Drain Valve: 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 through the vent holes in large amounts. You know that 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.

Check Valve: 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.

Before Starting

Break-in Procedure

Serious damage (for units with a tank) may result if the following break-in instructions are not closely followed.

This procedure is required before the air compressor is put into service and when the check valve or a complete compressor pump has been replaced.

1. Make sure the On/Auto/Off lever is in the "OFF" position. NOTE: Pull coupler back until it clicks to prevent air from escaping through the

quick connect.

Plug the power cord into the correct branch circuit receptacle.

(Refer to Voltage and Circuit Protection paragraph in the Installation section of this manual.)

3. Open the drain valve fully (counterclockwise) to permit air to escape and prevent air pressure build up in the air tank during the break-in period.

4. Move the On/Auto/Off lever to "ON/AUTO" position. The compressor will start.

5. Run the compressor for 15 minutes. Make sure the drain valve is open and there is minimal air pressure build-up in tank.

6. After 15 minutes, close the drain valve (clockwise). The air receiver will fill to “cut-out” pressure and the motor will stop.

The compressor is now ready for use.

How to Use Your Unit

How to Stop:

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

Before Each Start-Up:

1. Place On/Auto/Off lever to “OFF”.

2. Pull regulator knob out, turn counterclockwise until it stops. Push knob in to lock in place.
