1. Check the power delivered by your cigarette lighter socket. On lorries, 12V sockets are often of low power. The machine requires a minimum of 140W (minimum 12A fuse).
2. Do not use extension cords or power strips.
3. Test the machine in another vehicle.

If the machine doesn't work in another vehicle either, please contact our after-sales service sav@handpresso.fr to arrange for it to be repaired by our workshop.
