How to do a free move - in other words, how to get your carriage from one side of the machine to the other, without knitting, and without dropping stitches
Brother: Both part buttons in, set carriage to hold - hold is not necessary in most cases, but if you have needles in hold they may return to B position and drop the work.
Silver/Knitmaster: Use the carriage release lever, ie "pop the top"
Toyota: ??? Not sure, can someone tell me?
Note: with the Japanese machines, you can take the carriage off one end and move it to the other. It's not possible on my Passap E6000 because the colour changer and other things are in the way.
