SNAP CLOSURE

With the valve closed, make sure the trip rod is pushed fully into its sleeve, then lock the trip rod in this position by tightening the thumbscrew in the clutch top.
Slide Valve Thief: Open the valve by pulling it outward until the clutch pin holds it open.
Internal Valve Thief: Open the valve by pushing the lever down until the cock pin holds it open.
Put the bail assembly hook into the slot at the top of the trip rod sleeve.
Slowly lower the oil thief to the desired level in the tank.
Give the lowering line an abrupt upward jerk. This should trip the valve closed, making the sample ready for retrieval from the tank.
