At operating temperature, the hydraulic tank is hot and under pressure.Hot oil and components can cause personal injury. Do not allow hot oil or components to contact skin.Remove the filler cap only when the engine is stopped, and the filler cap is cool enough to touch with your bare hand. Remove the filler cap slowly in order to relieve pressure.
Care must be taken to ensure that fluids are contained during performance of inspection, maintenance, testing, adjusting and repair of the machine. 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 in Caterpillar machines.Dispose of all fluids according to local regulations and mandates.
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 hydraulic system and the maintenance requirements of the hydraulic system.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 in the hydraulic system.Obtain the S O S Sample
