4. Open the needle valve, and flush 1 liter (1 quart) of hydraulic fluid though the sampling assembly. This
fluid can be directed to a waste container or back into the HPU reservoir.
5. Obtain a sample of the hydraulic fluid after flushing the valve hose assembly.
a) Without closing the valve, quickly place the sample bottle into the fluid stream (keep the sample bottle
sealed until the sample is to be taken).
b) Fill the sample bottle (175 mL/6 oz) with fluid.
c) Close the valve on the hose valve assembly and cap the sample bottle.
6. Check the fluid qualities of the sample by comparing it to a small jar of clean hydraulic fluid. Clean hydraulic
fluid has an amber color.
Consult the table, “Appearance of Hydraulic Fluid Sample” for indicators of unacceptable fluid qualities.
