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.

ACCESSORIES

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 following illustrations).

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.

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.

Risk of Electrical

Shock. 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.

A09711

10ENG

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.

Risk of Unsafe Operation. Certain

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

1.Voltage supply to circuit must comply with the National Electrical Code.

2.Circuit is not used to supply any other electrical needs.

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.

Description of Operation

Become familiar with these controls before operating the unit.

On/Auto/Off Switch: Turn this switch "On/Auto" 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	Drain
condensation	Valve
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.

A09711

12ENG

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.

Check Valve

Pressure Release Valve: 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 "cutout" 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 after the unit reaches "cut-out" pressure.

Pressure

Release

Valve

Motor Overload Protector: 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.

How to Use Your Unit

How to Stop:

1.Set the On/Auto/Off lever to "Off".

Before First Start-up

Risk of Unsafe Operation. Serious

damage 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: If quick connect is installed, pull coupler back until it clicks to prevent air from escaping through the quick connect.

2.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.

NOTE: Always drain tank on a washable surface or in a suitable container to prevent damaging or staining surfaces.

13ENG

A09711

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.

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.

3.Attach hose and accessories. NOTE: The hose or accessory will require a quick connect plug if the air outlet is equipped with a quick connect.

Risk of Bursting. Too much air

pressure causes a hazardous risk of bursting. Check the manufacturer’s maximum pressure rating for air tools and accessories. The regulator outlet pressure must never exceed the maximum pressure rating.

How to Start:

1.Turn the On/Auto/Off lever to "On/Auto" and allow tank pressure to build. Motor will

stop when tank pressure reaches "cut-out" pressure.

2.Pull the regulator knob out and turn clockwise to increase pressure. When the desired

pressure is reached push knob in to lock in place. The compressor is ready for use.

NOTE: Always operate the air compressor in well-ventilated areas free of gasoline or other combustible vapors. If the compressor is being used to operate a sprayer DO NOT place near the spray area.

Risk of Unsafe

Operation. Unit cycles automatically when power is on. When servicing, you may be exposed to voltage sources, compressed air, or moving parts. Before servicing unit unplug or disconnect electrical supply to the air compressor, bleed tank of pressure, and allow the air compressor to cool.

To ensure efficient operation and longer life of the air compressor, a routine maintenance schedule should be prepared and followed. The following routine maintenance schedule is geared to a unit in

a normal working environment operating on a daily basis. If necessary, the schedule should be modified to suit the conditions under which your compressor is used. The modifications will depend upon the hours of operation and the working environment. Compressor units in an extremely dirty and/or hostile environment will require a greater frequency of all maintenance checks.

NOTE: See "Operation" section for the location of controls.

To Check Safety Valve

Risk of Bursting. If the safety valve

does not work properly, overpressurization may occur, causing air tank rupture or an explosion.

1.Before starting compressor, pull the ring on the safety valve to make sure that the safety valve operates freely. If the valve

is stuck or does not operate smoothly, it must be replaced with the same type of valve.

To Drain Tank

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

2.Pull the regulator knob out and turn counterclockwise to set the outlet pressure to zero.

3.Remove the air tool or accessory.

4.Pull ring on safety valve allowing air to bleed from the tank until tank pressure is approximately 20 psi. Release safety valve ring.

5.Drain water from air tank by opening drain valve (counterclockwise) 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.
