The Automatic Locating Collet on the tool positively notifies the operator when the desired sleeve is reached. Running through two consecutives seal bores located two feet apart, indicates a sleeve. Running through only one seal bore indicate a landing nipple.

Proof of Sleeve Shift. After completion of a shift, either open or closed, an attempt to repeat the operation ( in the same sleeve ) will give surface indication that the shift was performed.

Safety Release. If the sleeve is opened in the presence of a differential pressure in favour of the annulus, the pressure mechanism is held inoperative by flow until the pressure equalizes. During equalization maximum strain should be held on the Wireline string.

Emergency Release. The Shifting Tool has a shear pin release mechanism bellow the Shifting Digs for emergency release.

Delibrate Release. Even after Shifting Tool is seated in a sleeve, it can be released without shifting the sleeve.

Open / Close Sequence. Upward jarring opens the sleeve. This allows the use of Hydraulic or Mechanical Jars. Run in the inverted position, the tool will close the sleeve with downward jarring. At least 6 feet, without restriction, should be provided bellow the sleeve.
