Hot oil and hot components can cause personal injury. Do not allow hot oil or hot components to contact the skin.
Obtain the Sample and the Analysis
In addition to a good preventive maintenance program, Caterpillar recommends using S O S oil analysis at regular scheduled intervals in order to monitor the condition of the engine and the maintenance requirements of the engine.Each oil sample should be taken when the oil is warm and when the oil is well mixed in order to ensure that the sample is representative of the oil that is in the crankcase.Obtain the S O S Sample
Do not use the same vacuum sampling pump for extracting oil samples that is used for extracting coolant samples.A small residue of either type sample may remain in the pump and may cause a false positive analysis for the sample being taken.Always use a designated pump for oil sampling and a designated pump for coolant sampling.Failure to do so may cause a false analysis which could lead to customer and dealer concerns.
