Taking the Molle 3 apart into handy pieces is literally a piece of cake (if you know how to do it).
Roll the carriage all the way to the left and undo the carriage return string. Hook it to the pin on the right of the rear carriage rail.
Remove screw (number 1 in the top picture), or push and pull 1 and 2 slightly, to move the carriage beyond the blocking mechanism and take it off the machine.
Push the Caps and Figs keys and secure them.
