Technically fine. Motor control is faulty. It reacts late to the speed controller (potentiometer), so it starts jerkily. Unstable rotation during work. You can't turn it on with the green button, You can't turn it on with the green button.The green button puts it into operation by default,and then the direction of rotation can be selected.After every "F" or "R" switch off, the machine switches off completely, in all such cases, it must be put into operation with the green button.This does not ensure continuous work.The control panel is likely to be defective, Since the machine is under warranty, I do not perform measurements in the control unit.I have notified the technical team, I am waiting for their reply.Overall, the machine is good, so it is recommended for purchase.Service help, I will see how helpful they are.
