Well... they replied in English with two PDF files on how to use the system. Apparently they have two types of lancets so the user has a choice of just poking their finger manually or using their little spring loaded lancet.
With the spring loaded lancet you basically push down the plunger (actually it is the needle) to make the needle go into and load the spring mechanism. then you twist off the protective cover of the plunger to reveal the needle. Then you hold the lancet against the puncture site and push the trigger. The rest of the test I could figure out.
This is what was in my kit, though mine also had a small lancet separate so it is confusing. I don`t know if the thing they say is a lancet actually has a needle inside.

Hopefully I will get a response in English from the company but I am also hoping for some help here.
