2:GENERAL DESCRIPTION OF AIR COMPRESSOR
The air compressor pump works with the up and down of a piston in the cylinder. During the
down-stroke, ambient air is drawn in through the inlet valve, while the discharge valve remains closed.
On the up-stroke of the piston, the air is forced into the compressor tank through the discharge valve
and the check valve. Through this controlled action, air is forced into the tank to a preset pressure.
The pressure is regulated by the pressure switch. Working air is not available until the pressure in the
air tank built up. The air inlet filter openings must be kept clear of obstructions.
All tools require specific air pressure to operate properly. Consult your air tool manual for those
requirements and safety instructions. There are a variety of air tools available that will operate
efficiently with this air compressor. For best results, always compare the air tool requirements to your
compressor output specifications. A tool that requires a lot of continuous air, such as a sander, will not
operate effectively with a small tank compressor. A tool that requires little air, such as a brad nail gun,
will operate with a small tank compressor very effectively. Learn your air tool power requirements,
match your air tools to your compressor correctly and this compressor will perform effectively.
5.2:ELECTRICAL
3:ON RECEIPT INSPECTION
Each air compressor outfit is carefully tested and inspected before shipment. Every attempt is made
to ensure safe and complete shipment of our products. Please inform the dealers if any deficiency
was found.
4:GENERAL REQUIREMENT
Please ensure air compressor is installed correctly. Maintain and service on a regular basis.
Information included in this booklet describing the maintenance schedules and trouble shooting.
It is important that you read this information and keep it for future reference.
Please ensure that the air compressor is electrically connected in a safe and correct manner. Any
electrical work should be carried out by an electrician and installed in a way which meets all
applicable codes and regulations.
Failure to connect the air compressor correctly to power source 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, ensure the power source has been shut down to prevent personal injury or
damage to the unit.
If the supply cord is damaged, it must be replaced by the your dealer or its service agent in order to
avoid a hazard.
5:INSTALLATION
5.1:MECHANICAL
Located 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. 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 clean. A clean compressor runs cooler and
provides longer service. Allow room for easy access to the air compressor for maintenance and
service work.
5-2-1: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 power source will result in premature motor failure
and is not covered by this compressor or motor manufacture’s warranty.
5-2-2:THERMAL 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 for the motor to 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 acts as a pilot device activating the motor. The pressure switch cut in/cut out
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 improper pressure setting.
Consult your local distributor or service center if the switch malfunctions.

5-2-3-1:This pressure switch control the on/off of the compressor, it can be turn off manually but when
it is in the AUTO position, it allows the compressor to start or shut down automatically without
warning upon air demand. Always set this switch to OFF when the compressor is not in use
and before unplugging compressor.
6:BEARING LUBRICATION
The bearings in this unit are sealed bearings that contain sufficient lubricant to last their life.
No other lubrication is required.
7:START UP PROCEDURE
7-1: Check to see that nuts and bolts are all snug, this must be done, as some fasteners
may become loose in transit.
7-2: Check that compressor is on a strong, stable level base.
7-3: Check that air filter is clean.
7-4: Do not place any materials on or against the belt guard, or the compressor unit.
Obstacle materials will limit the cooling effect and could lead to premature failure.
5-2-4:AIR PRESSURE REGULATOR
The air pressure regulator allows you to adjust the line pressure for the tool in use.
Never exceed maximum working pressure of the tool. To adjust, pull up the knob, turn clockwise to
increase pressure or turn counterclockwise to decrease pressure.
7-5: Open the air receiver outlet valve and start the unit for no load operation. Allow the unit to
operate for a minimum of twenty minutes in no load condition.
7-6: After running the compressor for twenty minutes, close the valve and allow the unit to reach
5-2-5:GROUNDING INSTRUCTIONS
Do not modify the plug that has been provided, if it does not fit the available outlet, the correct
outlet should be installed by a qualified electrician. The plug must be plugged into an outlet that is
properly installed and grounded in accordance with all local codes. If these grounding instructions
are not completely understand or if in doubt as to whether the compressor is properly grounded,
have the installation checked by a qualified electrician.
maximum operating pressure. Ensure that the compressor shuts down at the preset
maximum pressure and the head pressure is released through the pressure switch.
7-7: Check the air compressor and piping systems for leakages and correct as required.
7-8: Shut off all power to the air compressor before attempting any repair or maintenance.
5-2-5-1:This product is for use on a nominal 115 or 230 volt circuit. A cord with a grounding plug as
shown here shall be used. Make sure that the product is connected to an outlet that matches
the plug. No adapter should be used with this product.
(FOR AREA OTHER THAN USA, PLEASE CHECK THE LOCAL CODE.)
5-2-6:EXTENSION CORDS
The use of any extension cord will cause some drop in voltage and loss of power. For optimum
performance, plug the compressor power cord directly into a grounded wall socket. Do not use an
extension cord unless absolutely necessary. It is better to use a long air hose to reach area where
work is being performance. If use of an extension cord can not be avoided, refer to the following
guidelines:
Use only 3-wire extension cord. Make sure your extension cord is in good condition. Be sure
gauge is sufficient to carry the current the unit will draw. Note that the smaller the gauge the
heavier the cord. Example: Gauge 10 is heavier than gauge 12.
