Page 5: General Information
General Information Description The Murphy LM2000 model maintains the crankcase oil level of an engine, pump or compressor. Adjusted to the correct running-oil-level, the LM2000 will replenish oil as it is used. An integral, low-level switch will alarm and/or shutdown the equipment if supply oil is lost and the equipment continues to use oil. -
