： This pressure switch turns the compressor ON and OFF . It is operated manually, but
5-2-3-1
when it is 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 in use and before unplugging compressor.
5-2-4 ： AIR PRESSURE REGULATOR
The air pressure regulator enables operator to adjust line pressure to the tool in use. Never
exceed maximum working pressure of the tool. To adjust pull up on knob and turn right to
increase pressure or left to decrease pressure.
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 understood, or if it is in doubt as to whether the
compressor is properly grounded, have the installation checked by a qualified electrician.
This product is for use on a 20A circuit. A cord with a grounding plug, as shown above,
5-2-5-1：
must be used. Make sure that the product is connected to an outlet having the
same configuration as the plug. No adapter should be used with this product.
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 performed. If use of an extension cord can
not be avoided, refer to the following guidelines before using ::
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. The smaller the gauge, the heavier
the cord.

6 ： COMPRESSOR LUBRICATION
Do not add or change oil while the compressor is in operation. Use the recommended SAE10-30W
non-detergent oil only.
6-1 ： FILLING THE OIL
6-1-1
： Remove the oil fill plug.
6-1-2 ：
Slowly pour the proper oil into the pump crankcase.
6-1-3 ：
Always keep oil level between "Up Level" and "Low Level" marks on the oil dipstick or
on the red circle on the sight glass.
6-2 ： CHANGE THE OIL
Change oil after the first 8 hours of compressor operation, then change oil after every 300
working hours or 3 months (whichever comes first).
6-2-1：
Remove the oil drain plug and allow oil to drain out.
6-2-2 ：
Replace the oil drain plug, then use a sealing compound or Teflon tape to avoid leakage.
6-2-3 ：
Refill with the recommended oil to the proper level
7 ： INITIAL START-UP PROCEDURE
Do not attempt to operate the air compressor unit without first checking the oil level in the pump
and adding oil as required. Serious damage may result from use without oil.
7-1：
Check to see that nuts and bolts are all snug, as some fasteners may become loose in transit.
7-2：
Check that proper oil type and level is correct (see above for proper compressor lubrication).
7-3：
Check that compressor is on a strong, stable, level base.
7-4：
Check that oil breather is clean.
7-5：
Check that air filter is clean.
7-6 ：
Do not place any materials on or against the belt guard or the compressor unit itself. Placing
materials there will limit the cooling of the air compressor and could lead to premature
failure.
7-7 ：
Turn the compressor ON .
7-8：
Open the air receiver outlet valve and start the unit. Ensure air is escaping to atmosphere. Allow
the unit to operate for a minimum of twenty minutes in this no-load condition to lubricate
bearings and piston.
7-9:
After running the compressor for twenty minutes, close the valves and allow the unit to reach
maximum operating pressure. Ensure that the compressor shuts down at the preset maximum
pressure and the head pressure is released through the pressure switch.
7-10：
Check the air compressor and piping systems for leakages and correct as required.
7- 11 ：
Shut of f of all power to the air compressor before attempting any repair or maintenance.
7-12：
Stop the compressor and check the oil level in the crankcase. Add oil as required.
7-13：
Your compressor is ready for use.
