PARTS DESCRIPTION
Electric Motor
The motor is used to power the pump. It is equipped with a thermal overload protector. If the motor
overheats for any reason, the thermal overload protector will shut it down in order to prevent the motor
from being damaged.
Air Compressor Pump
The pump compresses the air and discharges it into the tank via the piston that moves up and down in the
cylinder.
Safety Valve
This valve is used to prevent the compressor from building too much pressure. If the pressure reaches the
preset level of the motor, it will automatically pop open. You can also pull the ring on the valve to open
manually.
ON/OFF Switch
This switch turns on the compressor and is operated manually.When in the ON position, it allows the
compressor to start up or shut down automatically, without warning, upon air demand.ALWAYS set this
switch to OFF when the compressor is not being used and before unplugging the compressor.
Air Pressure Regulator
The regulator is used to adjust the pressure inside the line to the tool that is being used. Turn the knob
clockwise to increase the pressure and counter-clockwise to decrease the pressure.
Tank Pressure Gauge
The gauge measures the pressure level of the air that is stored in the tank. It cannot be adjusted by the
operator and it does not indicate the pressure inside the line.
Outlet Pressure Gauge
The gauge measures the regulated outlet pressure.
Quick Coupler
The quick coupler is connected to a quick connector which is connecting to air hose.
Drain Valve
The drain valve is used to remove moisture from the air tank after the compressor is shut off.
Air Tank
The tank is where the compressed air is stored.
Power Cord
This product is for use on a nominal 120-volt circuit and should be grounded. A cord with a grounding plug
as illustrated must be used. Make sure that the product is connected to an outlet that has the same
configuration as the plug (see Figure 1). No adapter should be used with this product. Check with a
licensed electrician if the grounding instructions are not understood or there is doubt as to whether the
product is properly grounded. Do not modify the the plug provided. If it will not fit the outlet, have the
proper outlet installed by a licensed electrician.
Improper installation of the grounding plug will result in a risk of
electric shock. If repair or replacement of the cord or plug is
necessary, do not connect the grounding wire to either flat blade
terminal. The grounding wire is in the green outer surface.

Set the ON/OFF switch to the ON position. The air receiver will fill to "cut-out"pressure
and then the compressor's motor will stop. The compressor is now ready for use.
Use a dedicated circuit. The compressor will use the full capacity of a typical 15A household circuit. If
any other electrical devices are drawing from the compressor's circuit, the air compressor may fail to
start voltage or an overload circuit can result in sluggish starting that causes the motor overload
protection system or circuit breaker to trip, especially in cold conditions.
Disconnect the power cord only after break-in process has been completed, otherwise the motor might
get damaged.

MAINTENANCE
Through normal operation of your air compressor, condensation of water
will accumulate in the tank. To prevent corrosion of the tank from the inside,
condensation must be drained at the end of every workday. Be sure to wear
protective goggles. Relieve the air pressure in the system then open the
drain valve on the bottom of the tank to drain. Under cold conditions it is
especially important to drain the tank after each use to reduce the chance
of problems resulting from the freezing of condensation water.
NOTE: Refer to instructions on how to drain tank (page 10).
Pull the safety valve daily to ensure that it is operating properly and to clear
the valve of any possible obstructions.
Check that all connections are tight. Small leaks in the tank,
hoses,connections or transfer tubes will substantially reduce the air
compressor and tool performance. Spray a small amount of soapy water
around the area of suspected leaks with a spray bottle. If bubbles appear,
repair, replace or reseal the faulty component. Do not over-tighten any
connections.
Before storing the air compressor:
Drain the tank
Check the valve
Test for leaks
Prior to
storing
• Drain tank (page 10).
• Use an air blow gun to clean all dust and debris from the compressor.
• Disconnect and wind up the power cord.
• Clean the ventilation openings on the motor enclosure with a damp cloth.
• Drain all moisture from the tank.
• Pull the pressure safety valve to release all pressure from the tank.
• WARNING:Storage covers could cause a fire resulting in death or serious injury.
• Store the air compressor in a clean and dry location.
• In cold weather, store the compressor in a warm building when it is not in use.
This will reduce problems related to starting the motor and the freezing of water
condensation.
-Do not place a storage cover over a hot air compressor.
-Let equipment cool for a sufficient time before placing the cover on the
equipment.
Storage
Check Safety Valve
Before starting the 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, contact a trained service technician.
How To Drain Tank
1. Set the ON/OFF switch to the O (OFF) position.
2. Unplug the power cord.
3. Turn air pressure regulator knob counter-clockwise to set the outlet pressure to zero.
4. Pull and hold ring on safety valve, allowing air to bleed from the tank until air pressure is minimized.
5. Place suitable container under unit to catch water.
6. Slightly tilt unit and turn drain valve counter-clockwise to open.
7. After the water has been drained,close the drain valve(clockwise). The air compressor can now be stored.
How to Clean The Air Filter
A dirty filter will reduce the unit s performance and life. To avoid any contamination inside the
pump, the filter should be cleaned weekly and replaced on a regular basis. The cartridge filter
should be cleaned with blow gun.
