Work carefully around an engine that is running. Engine parts that are hot, or parts that are moving, can cause personal injury.
Keep all parts clean from contaminants.Contaminants may cause rapid wear and shortened component life.
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, "Dealer Service Tool Catalog" for tools and supplies suitable to collect and contain fluids on Cat® products.Dispose of all fluids according to local regulations and mandates.
Note: The following oil pressure measurements are taken between the oil filter and the engine lubrication system. Before you begin this procedure, ensure that the area around the oil pressure port is clean and dry. Be careful not to introduce any form of contamination into the lubrication system during this procedure.
