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.
Accessories Storage Box
This compressor features an accessories storage box for easier storage. The following accessories (not
included) can be stored in the box.
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

MAINTENANCE
Weekly
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.
A dirty air filter will reduce air compressor performance and life. To avoid
contaminating the pump, the filter should be cleaned frequently and
replaced on a regular basis. Clean the cartridge filter by blowing on it with a
blow gun (page 10).
Before storing the air compressor:
• 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.
