I bought this lock a few years ago and have finally decided to play around with it.

With the lock came these barrel type things and a small allen key:

I assume these barrel things are to disable individual pins but I can't figure out how to get into the lock to install them! At the back of the plug (I think it is called) there are three grooves (at 3, 6, and 9 o'clock). I am reluctant to apply too much force here without being sure as I tried and the metal piece between 3 and 6 o clock moved slightly. I am concerned it could snap off.
Can anyone help me out and confirm what the barrel things are for, and how to use them!?
Thanks very much
