LeROI Rotary Screw Air Compressor w40-50ss

Remove surface dirt and dust from the exterior surfaces of the oil cooler and aftercooler, if required (Air cooled units)

Obtain an oil sample from the compressor oil system and have the sample analyzed for condition

Change oil and oil filter, if required, based on results of the oil analysis

Check the air cleaner and service as required

Drain water (condensate) from the oil reservoir. Close the drain valve securely when oil appears

Check the compressor oil reservoir oil level

Operate air receiver/oil reservoir pressure relief valve manually to make certain it will open before starting the unit

Visually inspect all air and oil lines and fittings for leaks. This includes the air cleaner and any inlet piping of the air induction system. Correct leaks as required

Start and run the unit at rated full load pressure long enough to reach normal operating temperature (N.O.T.)

Observe the air cleaner restriction indicator. If the restriction indicator shows a red 'flag', the air cleaner element must be cleaned or renewed

With the unit running, check the oil filter condition. Units with restrictor indicators, if indicator shows red, the oil filter element must be renewed. Units using dual gauges (located at top rear of the air end, near oil filter or instrument panel). Observe the pressure on both gauges, if the difference in pressure is 15 PSI or more the oil filter element must be renewed

With the unit running, check the separator element condition. On units with restrictor indicators, if the indicator shows red, the restrictor is too high. On units with dual gauges (located top of air/oil reservoir or on instrument panel) observe the pressure on both gauges, if the difference in pressure is 15 PSI or more the restrictor is too high

Warning: Always wear protective gear when handling oil.
