Maybe its just me, but I'm having problems setting the cutting blade on the machine. To me it seems like a cheap setup cos the blade holder can just slide out of the arm. You adjust the blade via a long bolt that is housed in plastic and you lock it of with a small nut. The nut comes lose half way through a job, which then you have to adjust again. Adjusting it by hand means that you are meant to move it only 0.1 of a millimeter which is near impossible. Any info would be great Thanks
