Step 5: Drain the Jack Oil
Place the bottle jack unit into a pan and drain the oil as best you can. On the bottle jack unit in one of the videos it was easy to work the plunger in order to extract more of the oil. The spring on the plunger is too strong for that on this jack. Be aware that additional oil will pour out of the jack in coming steps. Have a pan or newspaper available to catch it and minimize the mess.
