Warning: Replacement electrical parts cannot be returned, refunded or replaced in the event of a breakdown (unless the malfunction is immediate and it is proven that the problem comes from the part) for the following reasons that we advise you to apply:

- use an extension cord of 2.5² of wire, unwound and 10 m maximum

- do not plug the extension cord or the machine into an electric grinder

- if the machine is connected directly to the wall socket, check that other electrical devices requiring electricity are not operating simultaneously on the same electrical line which could cause an overload and therefore damage the electrical or electronic components.

- check that your tools are well sharpened: a tool that no longer cuts causes the motor or electrical components to overheat
