Criticisms are with me on the one hand, that the neck (not motor!) Gets too hot for the hand during operation, and have done so without load! Whether that is a lubrication problem or simply to tight manufacturing tolerances, the shrink is perhaps only, I can not say yet. Hand the machine is easy enough to spin; the transmission also has the necessary game. I'll be watching the problem further.
Criticism 2 is a consequence of the first, and concerns one probably. just me: Curious, I realized that disassembly of the gearbox of the machine for the purpose of assessment obviously konstuktionsbedingt relatively complex would be (but one probably is a trick I still do not see.). In the interest of preserving warranty I have such intervention attempts so far failed. Since more heavily loaded gearboxes an occasional cleaning and lubrication of the gears but is highly useful (especially when they are so hot), is the unnecessary complication in my eyes.
