Operating Procedures

Piping

Plastic or PVC pipe is not designed for use with compressed air. Regardless of its indicated pressure rating, plastic pipe can burst from air pressure. Use only metal pipe for air distribu- tion lines.

If a pipe line is necessary, use pipe that is the same size as the air tank outlet. Piping that is too small will restrict the flow of air. If piping is over 100 feet long, use the next larger size. Bury underground lines below the frost line and avoid pockets where condensation can gather and freeze. Apply pressure before underground lines are covered to make sure all pipe joints are free of leaks.

Connect the piping to the 3/8" NPT air outlet opening at the end of the air tank.

Additional Regulators and Controls

Since the air tank pressure is usually greater than that which is needed, a separate regulator is employed to control the air pressure ahead of any individual air driven device.

Separate air transformers which combine the function of air regulation, moisture and dirt removal should be used where applicable.

Break-in Procedures

Serious damage may result if the following break-in instructions are not closely followed.

This procedure is required:

1.Before the air compressor is put into service. (Before the hose is installed)

2.When the check valve is replaced.

3.When a complete compressor pump is replaced.

a.Set the pressure switch lever to the "OFF" position.

b.Plug the power cord into the correct branch circuit receptacle.

c.Turn the regulator clockwise (or open the shut-off valve), opening it fully, to prevent air pressure build-up in the tank.

d.Move the pressure switch lever to "ON/AUTO". The compressor will start.

e.Run the compressor for 30 minutes. Make sure the regulator, or shut-off valve, is open and there is no tank pressure build-up.

f.After 30 minutes, close the regulator by turning it counterclockwise or close the shut-off valve by turning the knob clockwise. The air receiver will fill to cut-out pressure and the motor will stop. The compres- sor is now ready for use.

Daily Start-Up Checklist

Perform the following checks before starting the compressor outfit.

1.Make sure that nothing is blocking the belt guard air openings or air filter inlet.

2.Pull the ring on all safety valve to make sure the valve moves freely and smoothly.

3.Check the oil level; add oil if necessary.

4.Clean or blow off fins or any part of compressor that collects dust and dirt. Compressor will run cooler and provide longer service.

5.Before attaching an air hose or accessory make sure the pressure switch lever is in the "OFF" position. Close the air regulator outlet by turning it counterclock- wise.

6.Attach hose and accessory

Start the compressor outfit and check the following:

1.With the outlet valve closed, start the compressor outfit. Allow the outfit to pump up to cut-off pressure.

2.Make sure that all controls are operating correctly. Refer to "Description of Operation" section of this manual.

3.Check all line fittings and piping for air leaks. Even minor leaks can cause the compressor to over work, resulting in premature breakdown or unsatisfactory performance.

4.Check for any unusual vibration and noise.

5.Check for oil leaks. Correct any leaks found.

6.Open shutoff valve. Your outfit is ready for use.

TOO MUCH AIR PRESSURE CAUSES A HAZARD- OUS RISK OF BURSTING. CHECK THE MANUFACTURER'S MAXIMUM PRESSURE RAT- ING FOR AIR TOOLS AND ACCESSORIES. THE REGULATOR OUTLET PRESSURE MUST NEVER EXCEED THE MAXIMUM PRESSURE RATING. ON MODELS HAVING ONLY A SHUT-OFF VALVE, YOU MUST INSTALL A REGULATOR BEFORE USING ACCESSORIES RATED AT LESS THAN 125 PSIG.

Compressed air from the outfit may contain water condensation and oil mist. Do not spray unfil- tered air at an item that could be damaged by moisture. Some air operated tools or devices may require filtered air. Read instructions for the air tool or device.

When You Are Finished:

7.Set the pressure switch lever to "OFF".

8.Close the shutoff valve.

9.Remove the air tool or accessory.

10.Open the shutoff valve and allow the air to slowly bleed from the tank. Close shutoff valve when tank pressure is approximately 20 PSI.

DRAIN TANK DAILY. WATER WILL CONDENSE IN THE AIR TANK. IF NOT DRAINED, WATER WILL CORRODE AND WEAKEN AIR TANK, CAUSING A RISK OF AIR TANK RUPTURE.

11.With tank pressure at approximately 20 PSI, open the drain cock and allow moisture to drain.

NOTE

If the drain cock valve is plugged, release all air pressure. The valve can then be removed, cleaned and reinstalled.

12.After the water has been drained, close the drain cock. The air compressor can now be stored.
