• Loosen setscrew (C) on knob using the allen wrench provided.
   
• Remove knob (D) from body of cylinder (B).
   
• The drive tab (J) must be aligned with the cylinder to install the cylinder into the lock mechanism. If the tab cannot be rotated to this position, push the pin (E) down with the ring wrench (F) included to disengage the stops and turn the cylinder shaft (B) until the drive tab (J) is aligned with the cylinder (G).
   
• Holding in this position, insert the cylinder body into door so the tab on the cylinder is inside of the lock.
   
• Rotate the shaft (B) that the thumb turn attaches to so that the top of the post moves toward the edge of the door or insert the key (A) into the cylinder and rotate so the top of the key moves towards the edge of the door (H). This will extend the deadbolt. If the post or key is rotated the wrong direction, it will rotate approximately 120 degrees and lock up where it cannot be rotated in either direction. If this happens, push the pin (E) down with the ring wrench (F) included to disengage the stops and turn the key (A) in the opposite direction until the deadbolt extends.
   
• Fix knob (D) horizontally on cylinder shaft (B) with setscrew hole (C) downwards.
   
• Tighten setscrew (C). Install cylinder screw.
   

TO REMOVE CYLINDER: Loosen and remove cylinder screw and repeat steps 1-4 above.
