The car jack is a tool used to lift vehicles. It is primarily used on the Satsuma to put on parts like wheels. Unlike the floor jack and motor hoist, the car jack can be picked up and carried in a vehicle. The handle of the car jack must be extended before use.
To extend the car jack, place it under the car in a place you want lifted and start left clicking on the crank. Right-click on the crank to wind it back down, one step at a time.
Be careful not to push the jack through the ground when positioning it, as you'll then have to go to the landfill to retrieve it.
