AIR COMPRESSOR - OWNER'S MANUAL

BREAK-IN PROCEDURES

After eight hours of running, check the oil level and look for any oil leaks. Turn the compressor off and bleed down the

tank pressure to about 20 psi and open the drain valve to allow all of the moisture to drain from the tank. Allow the pump to
cool and torque the head bolts and the bolts which hold the inner and after cooler.

We recommend that you change your oil after the first 8 hours of operation. This could help remove any small particles in
the pump and will improve the life of the pump.

After the first week of operation follow the guidelines in the MAINTENANCE SCHEDULE.

MAINTENANCE SCHEDULE

THE LIFE OF YOUR COMPRESSOR WILL BE DETERMINED BY HOW IT IS MAINTAINED.

- A clean pump will run cooler, causing less moisture in the tank and lines. Since the cooler the air is, the easier it is to

compress, cleaning of the pump will make the motor and pump run less and save you money.

- A clean air filter will allow you to compress more air per ciyle. A dirty air filter causes the oil from the crankcase to be

sucked up pas the piston rings if happens you get MAJOR problems. First, the oil gets into your air system, mixes with
the water vapor in the lines and creates a

“

”

that can foul up tools and destroy paint systems with

“

eye

”

. Secondly, the oil becomes baked onto the valve plates where it builds up and cuts the efficiency of the pump

dramatically.

- Clean oil at the proper level in the crankcase is your best insurance against pump failure.

- A dry tank will last many more years than a tank with water sitting in it rusting away metal. The tank is a great heat sink

and will take out the bulk the moisture that is in your air system

if you drain it

Turn off power before servicing and be sure the air tank is unloaded. These instructions are based on normal operating
conditions. If the compressor is located in an exceedingly dusty area, increase the frequency of all inspections.

- Inspect the compressor visually.
- Check oil level and add some if necessary, before turning the compressor on.
- Drain moisture from the piping system.
- Be sure there is no excessive or unusual vibration or noise.

- Remove and clean intake air filters; do not wash the filter element.
- Check V-belt for tightness. Belt tension should be adjusted to allow approximately 3/8" to 1/2" (9 to 13 mm) deflection with

normal thumb pressure, see Figure page 16.

- Clean cylinders externally, cylinder head, motor, fan blade, tubing, and tank.
- ASME safety valve should be tested manually to see if it is working properly.

- Check entire system for air leakage around fittings, etc by using water and soap lather.
- Check the pressure switch operation.
- Check for oil contamination and change it if necessary.
