You were trying to trim the beard...into what shape? What was your goal?
Trimming is pretty simple, but as you discovered the hard way, it's easy to take off too much.
I was trying to clean up my neck line mostly and trim away from the sideburns.
Personally mate, I recommend letting it be. A neckline should look natural, although if you really need it trimmed for work or preference I would say find a good barber. Someone specializing in men cuts, with beard experience. Again though: my first word of advice is leave the beard be. Let it do it's glorious job.
thanks!! i thought about this too.
My routine: Always double check the security of the guard, and the setting when trimming sideburns. I trim the neckline (without the guard, and with the finer narrower trimmer head) to about a finger width below my jawbone, curve under the chin appropriately to deal with (conceal) looser-than-desired skin, and repeat on the other side.

i learn my mistake. double and triple checking next time.
I'm too much of a chickenshit to use a guard to "even up" my beard.
I trim the long hairs when necessary to keep a roughly round shape, but I'd love it if I could just buzz the whole thing and come away with the same effect.
I'm just so hesitant because I once had an inexperienced female "barber" trim me with a guard, and wound up looking like a Chernobyl victim.
