Summary: A car jack is the primary tool for changing flat tires. Learn how to safely lift your automobile using an emergency jack in this free video.
" Hi! This is John on behalf of expertvillage.com. In this video clip, I will show you how to use an emergency jack which is also known as a spare tire jack. When you get your emergency jack from your trunk, what you will want to do is position it underneath your lift points on your vehicle and start cranking it up. Now with emergency jacks, nobody likes them, they are not very fun and they take forever but in case of an emergency, they work great. Once the jack meets that lift point, you want to continue to slowly raise it, and test to make sure that the jack is secure and continue to raise it some. Test it again and typically I will not have my hand underneath it while I raise it in case the jack slips out or the car falls, so you can continue to raise it up until you have your desired height.
