Turn the trimmer off. Put your thumb under the teeth of the attachment. Push Up. The attachment should snap off. Replace the beard trimmer in the slot. Hope this helps.

Do you have a beard trimmer/clippers that don't hold the charge? Time to change the battery and give your beard trimmer a second life. .... Wahl Trimmer All-In-One Lithium Ion Unboxing - TimmyTechTV - Duration: 6:32. by ...
welcome to genetics....a topical solution will work but you have to keep using it or the hair will go away. a brand name like rogaine is a topical one. but Im not sure if it is face approved.
Oiling the trimmer is very simple. It is only necessary to apply oil to the blades. Simply apply one or two drops of oil directly to the blades while running. This should be done before each use.
You should have gotten a bottle of the blade oil with your clipper. If you have also lost this, you can buy a bottle of Wahl clipper oil from shaveroutlet.com. see link below
After or during showering, when your skin is still moist and pores still open, shave in the direction of the hair growth. This is different for different people -- not everyone has the same patter of hair growth, so there is no one direction to shave in. This is the same advice for ladies who shave their legs and such, so that's how I know. If you use an electric razor, the direction may not matter.
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...
