For the safety, you must put the extra wheel beside the jack and under the car.
To remove the jack, turn the releasing button named 2 and let the car go down.
For the first 30°, you can set the down speed. The jack is pressurized, that means the rod will
automatically go in the tube. You will not have any free stroke after turning out the releasing
button. Be careful, don’t trap your hand with the jack pad, it will come fast. If you want to retract
the jack correctly, put the pin on the tube before closing the scroll wheel 2.
To pack the jack correctly, remove it from the car lifting tube, fold the pin over the tube jack. It
allows the part named 1 to move downward, let it down to the maximum and plug the pin to the
clip or the magnet.
Then you can fit the jack in your trunk and go back to racing.
