Set-Up

Break in the new Air Compressor as follows:

1. Turn the Power Switch off and unplug the unit. Insert a male coupler (sold separately) into the female Quick

Coupler and fully open all regulators and valves.

2. Plug in the Power Cord.

3. Turn the Power Switch ON.

4. Let the unit run for 30 minutes. Air will expel freely through the Coupler.

5. Turn the Power Switch OFF.

6. Unplug the Power Cord and remove the male coupler.

Connect a regulator valve, an inline shut off valve and a 1/4″ NPT air hose to the Quick Coupler (all sold

separately). The air hose must be long enough to reach the work area with enough extra length to allow free

movement while working.

NOTE: An in-line shutoff ball valve is an important safety device because it controls the air supply even

if the air hose is ruptured. the shutoff valve should be a ball valve because it can be closed quickly.

Depending on the tool which you will be using with this compressor, you may need to incorporate additional

components, such as an in-line oiler, a filter, or a dryer (all sold separately), as shown on Figure C and Figure D.

Consult your air tool’s manual for needed accessories.

Operation

WARNING! To prevent serious injury from accidental operation: turn the power Switch “OFF” and

unplug the air compressor from its electrical outlet before assembling or making any adjustments to the

compressor.

Read the entire important safety information section at the beginning of this manual including all text

under subheadings therein before set up or use of this product.

Compressor Area Set Up

1. Designate a work area that is clean and well-lit. The work area must not allow access by children or pets to

prevent injury.

2. Locate the Compressor on a flat level surface to ensure proper pump lubrication and to prevent damage to

the unit. Keep at least 12″ of space around the unit to allow air circulation.

3. Route the power cord from the compressor to the grounded wall outlet, along a safe path without creating a

tripping hazard or exposing the power cord to possible damage.

General Operation

1. IMPORTANT: First, turn the power Switch OFF. This releases tank pressure and allows the motor to

start freely, without tripping the Circuit Breaker.

2. Close the Drain Valve.

3. Close the in-line Shutoff Valve between the compressor and the air hose.

4. Plug the Air Compressor Power Cord into a grounded 120 VAC electrical outlet.

5. Turn the Power Switch ON.

6. Allow the Air Compressor to build up pressure until it cycles off.

NOTE: At the beginning of the day’s first use of the Air Compressor, check for air leaks by applying

soapy water to connections while the Air Compressor is pumping and after pressure cutout. Look for air

bubbles. If air bubbles are present at connections, tighten connections. Do not use the Air Compressor

unless all connections are airtight, the extra air leaking out will cause the compressor to operate too

often, increasing wear on the compressor.

NOTE: As long as the Power Switch is ON, the operation of the Air Compressor is automatic, controlled

by an internal pressure switch. The Compressor will turn on automatically when the air pressure drops

to 95 PSI, and will turn off automatically when the air pressure reaches 125 PSI.

WARNING! TO PREVENT SERIOUS INJURY AND DEATH FROM EXPLOSION: Do not adjust the internal

pressure switch. Any change to the automatic pressure levels may cause excess pressure to

accumulate, causing a hazardous situation.

7. Adjust the Regulator Knob so that the air output is enough to properly power the tool, but the output will not

exceed the tool’s maximum air pressure at any time. Turn the knob clockwise to increase the pressure and

counterclockwise to decrease pressure. Adjust the pressure gradually, while checking the air output gauge

to set the pressure.

8. Make sure the air tool’s throttle or switch is in the off position. Connect the air tool to the air hose.

9. Open the in-line Shutoff Valve.

10. Use the air tool as needed.

Maintenance and Servicing

WARNING! Procedures not specifically explained in this manual must be performed only by a qualified

technician. To prevent serious injury from accidental operation: Turn the power Switch “OFF” and

unplug the compressor from its electrical outlet before performing any inspection, maintenance, or

cleaning procedures. To prevent serious injury from compressor failure: Do not use damaged

equipment. if abnormal noise or vibration occurs, have the problem corrected before further use.

ATTENTION: Surface corrosion will occur on metal surfaces over time and the rate of oxidation depends

on factors such as proximity to the ocean and humidity or condensation of water vapour on metal

surfaces. To mitigate this, WD40 can be used to remove surface corrosion then, when applied

periodically, it will prevent rust from forming.

Cleaning, Maintenance, and Lubrication

1. Before each use, inspect the general condition of the air compressor. Check for:

− Loose hardware,

− Misalignment or binding of moving parts,

− Cracked or broken parts,

− Damaged electrical wiring, and

− Any other condition that may affect its safe operation.

2. After use, wipe external surfaces of the compressor with a clean cloth.

WARNING! if the supply cord of this compressor is damaged, it must be replaced only by a qualified

service technician.

Draining Moisture from the Tank

The Drain Valve is located under the Tank. It must be used daily to release all trapped air and moisture from the

Tank. This will eliminate condensation which can cause tank corrosion.

1. Turn the Power switch of the compressor off.

2. Place a collection pan under the Drain Valve.

3. Turn the Drain Valve lever downward to open it.

4. When all the pressure and moisture is released, close the Drain Valve.

Air Filter Maintenance

Check the Air Filter weekly to see if it needs replacement. If working in dirty environments, you may need to

replace the filter more often.

1. Remove the Cover.

2. Remove the Air Filter.

3. Replace with a new Air Filter.

4. Replace the Cover.
