2 ： GENERAL DESCRIPTION OF AIR COMPRESSOR
To compress air, the piston moves up and down in the cylinder. During the down-stroke, air is
drawn in through the inlet valve. The discharge valve remains closed. On the up-stroke of the
piston, air is compressed. The inlet valve closes and compressed air is forced out through the
discharge valve, through the check valve and into the air receiver tank. Working air is not
available until the compressor has raised the air receiver pressure above that required at the air
service connection. The air inlet filter openings must be kept clear of obstructions.
Your air compressor can be used for operating paint spray guns, air tools, caulking gun, grease
guns, air brushes, sandblasters; inflating tires and plastic toys; and spraying weed killer,
insecticides, etc. An air regulator is usually necessary for most of these applications.
3 ： INSPECTION
Each air compressor is carefully factory-tested and inspected before shipment. Every attempt is
made to ensure safe and complete shipment of our products. It is the responsibility of the
receiver of the goods to ensure the products has been shipped in full and have arrived in
suitable condition to avoid expenses being incurred to correct such problems. With improper
handling, damage may result in transit and cause problems in compressor operation.
4 ： GENERAL REQUIREMENTS
It is your responsibility to ensure air compressor is installed correctly, as well as maintained and
serviced on a regular basis. Information has been included in this booklet outlining the
suggested air compressor maintenance schedules and a troubleshooting guide. It is important
that you read this information and keep it in a safe place for future reference.
5 ： INSTALLATION
5-1 ： MECHANICAL
Place the compressor in a clean, dry, and well-ventilated area. The compressor should be
located 12-18 inches from a wall or any other obstruction that would interfere with the air flow at
intake/output points. Place the air compressor on a firm and level surface. The air compressor
is designed with heat dissipation fins that allow for proper cooling. Keep the fins and other parts
that collect dust or dirt clean. A clean compressor runs cooler and provides longer service.
Allow room for easy access to the air compressor for maintenance and service work.

5-2 ： ELECTRICAL
It is your responsibility to ensure that the air compressor is electrically connected in a safe and
correct manner. Any electrical work should be carried out by a competent electrician and
installed in a way which meets all applicable codes and regulations.
Failure to connect the air compressor correctly to your building's electrical services may result
in serious personal injury or damage to the equipment.
Please note that under normal conditions, the air compressor will operate intermittently. Should
it be necessary to service the air compressor, ensure the power source has been shut down.
This must be done to prevent personal injury or damage to the unit.
If the power supply cord is damaged, it must be replaced by the manufacturer or a suitable
qualified person in order to avoid a hazard.
5-2-1 ： MOTOR
Wiring must be done in a manner that full voltage nameplate ± 10% is available at the
motor terminals during startup. Use of an incorrect electrical motor for your particular
building service will result in premature motor failure and is not covered by
compressor warranty.
5-2-2 ： RESET SWITCH
Ensure that all guards and shrouds are in place before pressing reset switch to restart the
motor. If the motor shuts down because of overload, wait 10-15 minutes so the motor can
cool down, then press the reset switch to restart motor. The reset switch button is located on
the motor housing.
5-2-3 ： PRESSURE SWITCH
The pressure switch located on the compressor unit acts as a pilot device, activating the coil
on the magnetic starter. The pressure switch cut-in/cut-out setting has been preset at the
factory, do not tamper with the settings. Never bypass or remove this switch, as serious
damage to equipment or personal injury could result from too high of air pressure. Consult
your local distributor or service center should the switch not be operating properly.
