Operation

Warning!! Never attempt to adjust or removeValve Air Outlet (#A-9). It is pre-set at 170

psi. Removal of valve voids warranty.

Warning!! Before using your compressor for the first time,fill with oil.Running the com-

pressor with low,or no oil,voids the warranty.

1. Carefully and slowly unscrew the Oil Dipstick (#B-19) from the oil reservoir.The assembly

is made of plastic and will break if you are too forceful.

2. Check that oil reaches the full mark on the Oil Dipstick (#B-19). If not, fill with a standard,

non-detergent, 30-weight motor oil. Do not overfill. If overfilled, remove the drain plug and

drain appropriate amount.

Tool

For best service, you should incorporate an oiler, regulator, and filter, in line, as shown in the

diagram below. Hoses, couplers, oilers, regulators, and filters are all available from Harbor

Freight Tools.

1. Conncect your air hose to the 1/4” NPT.

2. Safety pre-check:

a. Make sure the drain valve at the bottom of the tank is closed.

b. Re-check the oil level.

c. Make sure the Valve Air Outlet (#A-9) is undamaged and functional.

3. Turn the Valve Air Outlet (#A-9) to the off position. In the off position, the handle is

perpendicular to the air hose fitting.

4. Turn on the compressor by pulling up the Air Pressure Switch (A-10). (To turn it off, push

the Air Pressure Switch (A-10) down.

5. Watch the Pressure Guage (#A-6) and allow the compressor to build up at least 80 psi.

6. After reaching 80 psi, open the Valve Air Outlet (#A-9) by turning it parallel to the air hose

fitting.This will pressurize the hoses and air tools. Check for air leaks and test your air tool.

7. When the Air Pressure Switch(A-10) is in the on position, the compressor is automati-

cally controlled by an internal pressure switch.The compressor automatically turns on when

the pressure drops to 80 psi, and turns back off when it reaches 110 psi.

Warning! Although the internal pressure switch is adjustable, changing the pressure

setting is not recommended; any change to the on/off pressure levels will cause addi-

tional stress to the motor, resulting in shortened motor life.

Note: If you need to quickly depressurize the air compressor, turn it off by pressing the Air

Pressure Switch (A-10) down, then, pull out the SafetyValve Ring (#A-4).

Operational Warnings:

1. To reduce the risk of explosion or fire, never spray flammable liquids in a confined area.

Make sure the work area is well ventilated. Never smoke while spraying. Never spray near

flames or sparks. Keep compressor away from all flammable objects.

2. Air from a compressor is not suitable for breathing purposes. Never inhale air from the

compressor.

3. Never alter or weld on the air compressor tank. Welding on a tank is extremely hazardous

and could affect tank strength; this may result in an explosion, causing severe injury or death.

4. Never use the compressor outdoors in the rain, or on a wet surface. Electric shock may

result.

5. Never make adjustments or work on the compressor when it is pressurized.

6. Never service or perform maintenance on the air compressor until it is depressurized and

unplugged.

7. When not in use, always put the Air Pressure Switch (A-10) in the off, or down position.

Maintenance

Warning! Make sure the compressor tank is drained and the compressor is unplugged

before attempting any maintenance.

Never use flammable liquids or solvents to clean the compressor. Clean with a mild detergent

and water. Be careful to not spill water onto electrical components.

Each use.

1. Check oil level. If needed, fill according to instructions on page 5.

2. Drain air tank. Turn the Water Valve (#A-5) clockwise. Reverse to close. It is good prac-

tice to leave it open between uses, to keep tank dry.

3. Check for worn or damaged cords or plugs.

After first 50 hours or 30 days.

1. Replace the oil. See the top of page 5.

2. Check to make sure fittings are tight.

3. Blow air and clean out the cylinder cooling fins on Cylinder Head (#B-5).
