For reference... In Canada, Princess Auto sells the X2 with an MT3 spindle as well, even though their catalog states it is R8.
The draw bar thread is not machine specific though, since it only passes through the machine. It's the accessory (end mill holder, collet, drill chuck, etc.) that determines the thread. I have accessories that use 3/8" draw bars and others that use M10 draw bars.
But, getting back on topic... On my X2, I loosen the draw bar a couple of turns to start. Now if the table is clear, I lower the head onto "something" to support the head. Usually though, there is a setup on the table and I'm changing cutters mid-project. In this case, I make sure to tighten the lock on the Z-axis. Now give a few light-medium taps. As mentioned before, this is better than a big whack. I use a small 4 oz. hammer for this. It's small enough to remind myself not to swing it to hard. This has always worked for me.
Every once in a while, I'll rub the inside of the spindle taper with an oily rag to clear out any possible chips. Just remember to dry it off before using - you don't want oil in there. All collets, chucks, etc also get a quick rub with an oily cloth and a dry down before being installed.
