Repair by Garland

If the generator has to be repaired by the manufacturer, please enclose an exact description of the error. If possible, use the original package for the return. If it isn’t available, do not use porous material for wrapping (like styropor). This could enter the unit and the electronic parts and is difficult to remove.
