it seems to me that you have a semi automatic gear, which as far as i know very similar to an automatic gear, the only difference is that you change gears.
what you should do, is start in Neutral, change to 1st gear and drive. when the RPMs goes to high, leave the throtle and change to 2nd gear, like you'd do with a regular gear, the clutch is automatic. do so with any gear change, just don't lower gears when you're to fast for it.
I have to say that I'm not familiar with the model, and I'm not a Mechanic.
