TUBE AS 5096852 - Caterpillar

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 to relieve pressure.
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.
Always use a designated pump for oil sampling, and use a separate designated pump for coolant sampling. Using the same pump for both types of samples may contaminate the samples that are being drawn. This contaminate may cause a false analysis and an incorrect interpretation that could lead to concerns by both dealers and customers.
Obtain the hydraulic oil sample as close as possible to the recommended sampling interval. In order to receive the full effect of S O S oil analysis, establish a consistent trend of data. In order to establish a pertinent history of data, perform consistent oil samplings that are evenly spaced.Obtain a sample of the steering and brake hydraulic system oil on this machine from the filler tube of the hydraulic oil tank. The steering and brake hydraulic oil tank is located on the left-hand side of the machine beneath the left-hand cab platform.
Operate the machine in order to warm the oil.
Park the machine on level ground. Lower the implement so that the bucket is placed flat on the ground with a slight downward pressure.
Engage the parking brake and stop the engine.

Open access door (1) in the platform on the left-hand side of the cab.
Press the button on breaker relief valve (2) in order to relieve any tank pressure.
Slowly remove filler cap (3). Remove filler strainer that is inside of the filler tube.
Clean the filler strainer and the filler cap in a clean nonflammable solvent.
Keep the lids in place on empty sampling bottles until you are ready to collect the sample. Complete the information on the label for the sampling bottle before you begin to take the sample.
Collect the sample from the hydraulic tank filler tube. Use a designated pump to collect the sample in order to avoid contamination. Note: Keep the sample suction tube above the bottom of the tank at all times.
Do not collect a sample from the hydraulic tank drain.
