I just wanted to add a few bits to this.
While I'm very confident that the machine can be used and that it has no problem with any of the major components, it is what it is. An old machine that is not perfect. It is modified so some of the HM features are not there any more.
For example if your water ran out I believe the machine in it's original state would shut down to protect the pump. This machine doesn't. Making sure you always have enough water is important. Or if you loose pressure at the wand for whatever reason, shut it down asap. Most of the time when this happens it is because the strainer at the header tank is blocked and it's a simple job but pumps don't like running dry. Also the machine doesn't shut down when the waste tank is full. None of this stops the machine from being useable but it does mean you will need to have a handle on these things while working. For anyone looking to get into the TM world I would strongly recommend that you have some technical know how or it is going to be tough going. I'm not trying to put you off but I don't want you to think that using a TM is plain sailing. I am pretty good at the technical stuff and as such have a good understanding of the machine and the potential pitfalls. In my view that is essential for anyone considering getting a TM.
Phil I have put this on here for your benefit really as you sound a decent bloke and I don't want you to be disappointed. But also I have put it on here to so it's plain that I have pointed out what the machine is all about. It's a great deal if you are prepared to take it on but just don't do it Lightly.
