I had recently put together one that may or may not be the same - the head seperated from the body, and a small spring loaded detent inserts in the backside that "locks" the head at steadily increasing disances (lengths). The hardest part to assemble is the switch: which the outer slider is installed first, then the switch assembly (w/Small printed circuit board ) is slid very deeply into the plastic body of the shaver - you'll see where it locks into place. Then the lower circuit board and prongs attach at the bottom (also you can see where it locks in). Lastly, the battery is installed within its' holder and snaps into the plastic case. The two pars of the cases are then mated and click-lock into place (Think there's a single phillip's screw to keep it locked). Lastly, the blade cover snaps into place from the top, and you should be good to go - I never got to take it apart, but I had to put it back together...I believe that's how it goes, and mine works - there is no allowance for error, and it looks to me that if it's not 100% right it won't go together anyhow - good luck...
