Failure to properly follow all the instructions and precautions can cause you and others to be seriously hurt or killed.
Introduction
This air compressor features a compact structure, stable, performance, a high airflow rate, easy operation and low maintenance. Because the air compressor produces no oil in the airflow, it can be used for air supplies that need oil- free air.. The motor directly drives the pistons and does not need any lubrication or oil to function for a long period of time.

Assembly

1. Attach the air hose to the 1/4” Industrial Male “Push to Connect’ Quick Coupler.
2. Make sure the drain valve is off and that the power switch is in the OFF position.
3.  Ensure that the power supply you are going to use is operating  normally.Use a dedicated 220 Volt 60 Hertz circuit
4. Insert the power supply cord into the power supply socket. (NEMA 6-15R)

Test Run
Before using the air compressor for the first time, complete a test run as follows:

1. Turn the power switch to the OFF position. Plug the power cord into a power supply socket. Start the air compressor by turning the power switch to the ON position. The pressure gauge reading will slowly rise as pressure increases inside the air tank. When the gauge reading reaches 125 PSI (+/- 5 PSI) the pressure switch will automatically turn the power off. This indicates the compressor is working normally.  Turn the power switch to the Off position, unplug the power supply cord and release the air from the drain valve.
2. At this point proceed to the next step (daily operations) starting the air compressor to continue to use.
   Note: If the Air Compressor is not working properly, the pressure gauge will indicate that there is a decrease in pressure in the air tank. If there is an air leak from the compressor the pressure in the air tank decreases, the pressure switch resets and the motor automatically turns back on.

If you detect an air leakage, turn the power switch to the Off position, release the air from the tank by pulling on the safety valve. Unplug the power supply cord and contact
Customer Support for Assistance.

2. Unplug the power supply cord.
3. Reduce the pressure in the air tank through the air supply hose.

MAINTENANCE

Draining the Air Tank
The frequency at which you should drain the air tank depends on the environmental conditions and the amount of operating time logged.
Daily draining is recommended to not damage the air compressor motor, tank and other components.

1. Place the air compressor above a container capable of holding water. A pan with a dry towel would be advised.
   Locate the drain valve at the bottom of the air tank.

2. Without compressed air in the air tank, slowly turn the drain valve knob to the forward (open) or straight down position.
   The water in the air tank will drain out.

3. After all of the accumulated water has drained out, turn the drain valve knob to the closed or left position in order to avoid leakage.
   Draining the air tank protects parts from rust and corrosion

Changing the Air Filter
The air filters are designed to reduce noise and help prevent particulates in the air from entering and damaging the air compressor.
After being used for a period of time, the air filter will become clogged. This will reduce the air intake capabilities of the air compressor, reducing performance. Therefore, the air filter must be replaced regularly.

1. Open the lid of the air filter and remove the old air filter element.
2. Replace with a new air filter element and close the lid.

Testing for Leaks
Make sure all connections are tight. Do not overtighten.
A small leak in any hose or pipe connection will reduce the air compressor’s performance.
To test for small leaks, spray a small amount of soapy water on the area suspected of leaking. If the soap bubbles, replace the broken part.
Cleaning
Clean items with a soft brush, or wipe with a moistened cloth using a biodegradable solvent.
Do not use flammable liquids such as gasoline or alcohol. Always keep parts clean from dirt and dust for better performance.

STORAGE

Before storing for a prolonged period of time:

1. Turn off the power supply.
2. Disconnect the power cord from the power supply.
3. Pull the relief valve and release all the pressure from the air tank.
4. Clean the air compressor to remove all dirt and dust.
5. Cover the air compressor with a cover to protect the unit from dust and moisture.
6. Do not stack or store any items on top of or around the air compressor. Damage could occur.

CAUTION
TO REDUCE THE RISK OF ELECTRIC SHOCK, DO NOT EXPOSE TO RAIN. STORE INDOORS.
