Well I believe it's just a rebadged Hudy, so the requirements are probably the same or at least close. The Hudy calls for 25 amps continuous. Good luck.

I would agree with that...I have a PS made from a computer Pwr.Sup., which puts out 10 amps, and if your taking 2-3mm's it'll kick off.

I've used one of those automotive jump starters to power one, cutting every tire around and it still works.

It depends on cut depth as the other guys have said. 15 amps will allow you to pull 2-3mm off a 40 shore tire. With the HUDY carbide bit you can take more. When the blade gets dull you can take less.

I have one and thought the same thing...no instructions?

If you look very closely at the one piece of paper you got with the unit, there's some basic stuff.

As far as the current draw, I haven't had any problem with my 30 amp supply or a car battery. It's not made to take more than about 1mm at a time, and that's pushing it. Any more than that and you probably get alot of smoke and chunking. I would suggest using a rasp with the machine turned on high speed to take large amounts quickly.
Also, I have found that if you dont want to spend the money for a hudy carbide blade, a bosch metal 14 tooth/inch jigsaw blade works a bit better than the stock for smoothness. The stock blade looks like a 12 tooth/inch bosch wood jigsaw blade.
