Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the product. Be prepared to collect the fluid with suitable containers before opening any compartment or disassembling any component containing fluids.Refer to Special Publication, NENG2500, "Caterpillar Tools and Shop Products Guide" for tools and supplies suitable to collect and contain fluids on Caterpillar products.Dispose of all fluids according to local regulations and mandates.
S O S Services is a highly recommended process for Caterpillar customers to use in order to minimize owning and operating cost. Customers provide oil samples, coolant samples, and other machine information. The dealer uses the data in order to provide the customer with recommendations for management of the equipment. In addition, S O S Services can help determine the cause of an existing product problem.Refer to Special Publication, SEBU6250, "Caterpillar Machine Fluid Recommendations" for detailed information concerning S O S Services.Refer to the Operation and Maintenance Manual, "Maintenance Interval Schedule" for a specific sampling location and a service hour maintenance interval.Take the oil samples as close as possible to the standard intervals. To receive the full value from S O S oil analysis, you must establish a consistent trend of data. To establish a pertinent history of data, perform consistent oil samplings at set intervals.Operate the machine for a few minutes before you obtain the oil sample. This will thoroughly mix the oil for a more accurate sample.Reference: Refer to Special Publication, PEHP6001, "How To Take A Good Oil Sample" for more information about obtaining an oil sample.Consult your Caterpillar dealer for complete information and for assistance in establishing an S O S program for your equipment.Location of Sampling Valves

The cooling system is not equipped with sampling valves. Obtaining a sample of the coolant will require a vacuum pump or an equivalent. Slowly remove the cooling system pressure cap on the top of the radiator and withdraw the coolant through the filler opening.More Frequent S O S Sampling Improves Life Cycle Management
Traditionally, the suggested S O S sampling intervals have been at each oil change (250 hours for engines and every 500 hours for all other compartments). However, more frequent oil sampling is recommended in severe applications. If the machine is operated under a high load and/or in high temperature conditions, sample
