Please take extra care to read the supplied instructions YOU MUST NOT TAKE OUT THE ADJUSTMENT SCREW FOR MOTOR as we have adjusted it already (just remove the 2 little screws holding the motor mount plate) ....if it's not done correctly the beval and pinion gear will strip and that will mean it's not been adjusted correctly. Getting it right is super easy so what are you waiting for 😁
