If you have to ask how to educate a horse to a new bit, that particular bit is much too strong and complicated for your skillset.
I always educated my horses to the plain snaffle, and then with many years of training, I will educate them to a medium port curb bit. Never had any problems with doing so.
I've ridden horses in Tom Thumbs, and the only thing you can do is NOT touch the bit because most horses aren't educated to it, and it is intrinsically a confusing bit to teach a horse to navigate, especially if you don't know how.
Get a plain snaffle with no shanks and teach your horse to flex and bend in that bit by direct-reining and using leg pressure. Educating your horse to the snaffle is simply a matter of pressure-and-release, and teaching the horse to use the sides of the bit in order to avoid the nutcracker effect when both reins are pulled directly back. Leg aids should work in conjunction with the use of the bit.
