7. operaTion
7.1 before operaTinG your new air compressor
Please check the following points carefully:
1. Check that all nuts and bolts are secure.
2. Make sure oil has been properly added to compressor.
(See installing the Oil and Oil Breather section)
7.2 iniTial sTarT-upprocedure
1. Open the Air Tank Drain Valve to permit air to escape preventing air from pressure buildup in Air Tank.
2. Run the air compressor for a minimum of 20minutes in this “up-load”position to libricate the piston and
bearing.
3. Close Air Tank Drain Valve . Your compressor is ready for use.
Depending on the CFM draw of the tools being operated, your new Air C ompressor can be used for operating
paint sprayers, air tools, grease guns, air brushed, caulking guns, abrasive blasters, tire & plastic toy inflation,
spraying weed killer and insecticides, etc. Proper adjusting the Air Pressure Regulator is necessary for all of these
operations. Refer to the air pressure specifications provided with the tool you are using.
7.3 General overview
To compress air, the piston moves up and down in the cylinder. On the down stroke air is drawn in through the
valve inlet. The discharge valve remains closed. On the upstroke of the piston air is compressed; the inlet valve
closes and air is forced out through the discharge valve ,through the check valve, and into the air tank. Working
air is not available untill the compressor has raised; the tank pressure above that required in the air service
connection. The air inlet filter openings must be kept clear off obstructions, which could reduce air delivery of the
compressor.
7.4 insTallaTion and locaTion
Locate the compressor in a clean, dry and well ventilate area. The compressor should be located 12 to 18 inches
against walls or any other obstruction which would interfere with airflow. Place the compressor on a firm, level
surface. Keep all of spare parts which collect dust or dirt clean. A clean compressor runs cooler and provides
longer servisce. Do not place rag, containers or other materials on top of the compressor.
7.5 connecTinG To power source
This Air Compressor is designed to operate on a properly grounded 220 (110) V, 50(60)HZ, single phase,
alternating current (AC) power source. It is recommended that a qualified electrician verify the ACTUAL VPLTAGE
at the receptacle into which unit will be plugged and confirm that the receptacle is properly fused and grounded.
The use of the proper circuit size can eliminate nuisance circuit breaker tripped whie operating your air
compressor.
7.6 exTension cords
For optimum Air Compressor performance an extension cord should not be used unless absolutely necessary. If
necessary, care must be taken to select an extension cord appropriate for use with your specific Air Compressor.
Select a properly grounded extension cord which will mate directly with the power source receptacle and the Air
Conpressor power cord without the use of adapters. Make certain the extnsion cord is properly wired and in good
electrical condition. Extension cords must be #14 gauge or I mm2 at the smallest. Do not
use an extension cord over 25ft. in length.
7.7 aTTachinG an air hose
Your Air Compressor is ready to accept air hoses with (1/4”)Male Plug or (1/4”)Female Hose End. To install an air
hose into Air Cock or Air Quick Coupler, equipped with proper conneeter. Verify that air hose is
securely connected to Air Outlet by pulling lightly on air hose.
Note: Use only Air Hoses rated for use with 115PSI air pressure or higher.
