Ingersoll Rand Mobile Compressor 9/300HA

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: This inspection requires trained personnel with PPE!

Scavenge line clear of any obstruction

Orifice, check valve and hoses examined

No oil carryover into the discharge air

Cleaned the exterior of the filter housing?

Removed the filter element by releasing the nut?

Is the safety element to be renewed?

Cleaned the interior of the filter housing prior to removing the safety element?

Checked for cracks, holes or any other damage to the element?

Checked the seal at the end of the element and replaced if any sign of damage is evident?

Assembled the new element into the filter housing ensuring that the seal seats properly?

Secured the element in the housing by hand tightening the nut?

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.;
