6.
Remove the cap from the sample coupler and clean the coupler with a clean rag.
7.
Push on the coupler spring ball using a small tip to purge oil before taking a sample. The residual
pressure in the system will push the oil out of the coupler. Use a small container to recuperate the
oil that will come out. Let the oil leak for a few seconds (about half a cup). In this operation, the
pump must be engaged.
Taking an Oil Sample
Once you have released the residual pressure, you can take the sample.
To do so:
1.
Remove the sample kit from its bag and, using a screw driver, remove the vent cap from the bottle
cap.
