Taking oil samples under a running machine may cause personal injury or death. The use of a sample tube allows an oil sample to be taken while the person is outside of the tread path of the tires. The sample tube should be attached to the sample port when the machine is not running. The oil sample should then be taken only when the following conditions exist:
The machine transmission is in NEUTRAL.
The parking brake is applied.
The swing lock pin is engaged.
All implements are lowered to the ground.
The hydraulic lockout switch (if equipped) is applied.
Attach a hose with a female quick disconnect fitting to the hydraulic quick disconnect fitting. Note: Ensure that all personnel are clear of the machine before starting the engine.
Turn the engine start switch in order to start the engine.
Use the hose in order to obtain a sample of the hydraulic oil. Note: Allow oil to pass through the hose for 10 seconds before obtaining the sample in order to ensure that no contaminants are in the oil sample.
Turn off the engine.
Remove the hose that was used to obtain the oil sample. Refer to Special Publication, SEBU6250, "S O S Oil Analysis" for information that pertains to a sample of the hydraulic oil. For additional information about taking an oil sample, refer to Special Publication, PEHP6001, "How To Take A Good Oil Sample".
