Ingersoll Rand Mobile Compressor 9/270HA

Warning: This procedure requires trained personnel only!

Is the service valve adjusted to maintain normal operating discharge pressure and full speed position?

Does the tachometer move away from the full speed position before normal operating discharge pressure is attained?

If yes, turn the adjusting screw ‘A’ clockwise to increase the pressure.

Is the optimum adjustment achieved when the throttle just moves from its full speed position and the pressure increases slightly?

Has the engine slowed to idle speed?

CAUTION: Never allow the idle pressure to exceed maximum allowable pressure.

WARNING: Do not remove the filter(s) without first making sure that the machine is stopped and the system has been completely relieved of all air pressure.

• Clean the exterior of the filter housing and remove the spin–on element by turning it in a counter–clockwise direction.

CAUTION: If there is any indication of the formation of varnishes, shellacs or lacquers on the filter element, it is a warning that the compressor lubricating and cooling oil has deteriorated and that it should be changed immediately. Refer to LUBRICATION later in this section.

• Clean the filter gasket contact area and install the new element by screwing in a clockwise direction until the gasket makes contact with the filter housing. Tighten a further 1/2 to 3/4 of a revolution.

CAUTION: Start the machine and check for leakage before the machine is put back into service.;

Remove Y–strainer screens at the bottom of the moisture separator and both filters and clean out any residue

Verify that the orifices below the Y–strainers are not clogged

Verify that the piping from the orifice purge points to the exhaust system is not clogged

Disconnect the switch, the machine should shutdown.

At twelve month intervals, test the low engine fuel level switch by removing and operating the float manually
