Workshop Air Compressor is designed to be compact and portable and
used for air tool applications, inflation and nailing tasks, and heavy DIY automotive
applications. This compressor is equipped with pressure switch, air tank, pump and
motor with automatic reset thermal overload protector. The compressor is factory
lubricated and does not require any oil.
AIR COMPRESSOR COMPONENTS
AIR FILTER
• The air filter is a porous element contained within a metal or plastic housing. The filter is
attached to the compressor cylinder head for removing impurities from the air intake of the
compressor.
AIR TANK
• This air tank is a cylindrical component which is used to store the compressed air.
CHECK VALVE
• This valve prevents backflow of compressed air from air tank to the compressor pump.
MOTOR
• The motor provides rotational force necessary to operate the compressor pump.
PRESSURE REGULATOR KNOB
• The knob can be adjusted to regulate the pressure at the air line outlet of the compressor. Turn
the knob clockwise to increase pressure and counter-clockwise to decrease pressure.
PRESSURE SWITCH
• The switch automatically controls the on/off cycling of the compressor. It stops the
compressor when the air pressure in the air tank reaches the cut-off pressure, and restarts the
compressor automatically when the air pressure drops below the cut-in pressure.
Cut-in pressure: The low pressure (160 PSI) at which the motor will automatically restart.
Cut-off pressure: The high pressure (200 PSI) at which the motor will automatically shut off.
PUMP
• The pump is used to compress the air and discharge the compressed air into the air tank via
the reciprocating piston contained within the cylinder.
REGULATED PRESSURE GAUGE
• The gauge is used to measure the regulated pressure at the air line outlet.
PRESSURE RELIEF VALVE
• This valve will activate automatically if the pressure switch does not shut down the motor in
case of abnormally high pressure in the air tank. To operate manually, pull the relief valve ring
to relieve air pressure in the tank.
TANK PRESSURE GAUGE
• The gauge indicates the pressure level of stored air in the air tank. It is not adjustable by the
operator.
THERMAL OVERLOAD PROTECTOR
• This protector will automatically turn off the compressor if the temperature of the electric
motor exceeds a predetermined limit. If the thermal overload protector is actuated, the motor
must be allowed to cool down before restarting.
AUTO/OFF SWITCH
• This switch is operated manually to turn ON/OFF the compressor. In the AUTO position of
the lever, the compressor shuts down or starts up automatically based on air pressure level in
the air tank. Always set this lever to OFF position when the compressor is not being used and
before unplugging the compressor. To reset the motor overload condition, toggle the AUTO/
OFF lever to OFF position and unplug the compressor from the power outlet. Allow the motor
to cool for 10 minutes. Then plug in the compressor and restart it.
