Hold cocking piece to the rear and rotate bolt sleeve left (counterclockwise) to remove firing assembly from bolt. Release cocking piece, pull front end of mainspring towards rear, tilt firing pin to disconnect doll's-head joint.  

Stop and think if you really need to do the tricky stuff.

If so, drop extractor retaining pin downward to remove extractor.  The pin may be staked in place and should then be left alone unless you have to replace the extractor or sleeve. Turn safety to vertical (note little "exit ramp" for detent) and pull out to rear of sleeve.  Good luck getting it back in (best done with a small wedge to depress detent).
