MetricLathe Machine Threading Chartpdf

Hello I am trying to cut .1mm X 30mm thread in aluminum on my lathe, I dont understand what the chart on the machine is trying to tell me and I lost the useless Chinese owners manual long ago, can anyone walk me through how to make it work?

Man, I haven't done manual threading on a lathe since high school, that's going back a couple decades, and then some! Not being familiar with your machine, I don't have a lot to offer you. I would suggest posing your question on an actual machining forum, such as CNCZone.com or PracticalMachinist.com (hope you have thick skin for the latter)

Been  a long time for me also, but I do remember that you will need to change the actual gear on the machine to cut a metric thread. The chart there shows which gear you need for metric and standard. So first determine which gear is already installed. Then look at the chart on your machine for your desired pitch, then set your levers to match the chart for that pitch, the ABC levers, also have to set the lever on the bottom with all of the holes. If this is your first time cutting threads on a lathe, be aware that to stop the thread is different than hitting the foot brake. If this is the first time you are cutting threads on the lathe, machine them away from the chuck. Also make sure that on the carriage, there is a lever that you have to pivot into the lead screw, this coordinates the spindle to the lead screw. This lever usually has 1234 on it. The idea is to engage the feed lever with either 1 or 3, or 2 and 4, never 1 and 2, either odd or even. This will bugger the threads if you don't engage the lever the same way. For some practice runs, just cut really far away from the chuck to get a feel for it, how your lathe works.
