Raising a vehicle involves a certain amount of risk. If done correctly, it poses no danger to you or anyone else with Spiral Jack. But if done incorrectly, it could cost you your life!
SAFETY RULE #1: NEVER trust a jack, and NEVER crawl under a vehicle supported by a jack alone. Always position a pair of sturdy jack stands under the frame, subframe, axle or control arm(s) to prevent the vehicle from falling on you. Cinder blocks, wooden boards, logs, old wheels, metal cans or anything else that may be laying around are NOT jack stands and should NEVER be used to prop up a vehicle.
ways place the transmission in gear or Park, set the parking brake and/or block the wheels with a brick, chunk of 4x4 or a safety chock to prevent the vehicle from moving or rolling when you are jacking it up.
If you are raising one or both FRONT wheels off the ground on a Rear-Wheel Drive (RWD) or Four-Wheel_drive (4WD) car or truck, the parking brake and/or transmission should keep the vehicle from rolling. But if you are raising the REAR wheels off the ground, you must block the front wheels to prevent the vehicle from moving.
If you are raising one or both FRONT wheels off the ground on a Front-Wheel Drive (FWD) car or minivan, the parking brake should hold the rear wheels. You should still block the rear wheels because the parking brake may not hold tight enough to prevent the vehicle from moving. If you are raising the REAR wheels on a FWD car or minivan off the ground, the transmission should hold the front wheels. Blocking the front wheels is still a good idea for an extra margin of safety.
If you are raising all FOUR wheels off the ground on any type of vehicle, block the wheels on the front, then raise the rear wheels off the ground. Position safety stands under the rear axle, control arms or frame to support the rear of the vehicle, then lower the jack so the weight is fully supported by the stands. Make sure the vehicle is stable before raising and supporting the front wheels.
SAFETY RULE #3:Always work on a relatively FLAT surface. Don't jack up a vehicle if it is sitting on an incline or a hill. A slope of only a few inches can be enough to cause a vehicle to roll when it is raised off the ground.
SAFETY RULE #4:If you will be working under your vehicle, tell someone so they can check on you periodically. Or, have a cell phone in your pocket so you can call someone should something go wrong and you find yourself trapped or pinned under your vehicle. If you follow the first three safety rules, this rule should not be necessary.
SAFETY RULE #5: When raising a vehicle, position your floor jack under the lift points indicated in your owners manual. On most late model vehicles, the factory lift points for the factory scissor jack are flattened areas along the rocker arm pinch welds on both sides of the car. But with a floor jack, you want something more substantial to support the weight of the vehicle. Position the jack under an axle, control arm, subframe or frame. Do not place it under any sheetmetal, the engine oil pan, steering linkage, radiator support or other such components. Make sure there are no fuel lines, brake lines or vent hoses between the jack and vehicle when you raise it.
SAFETY RULE #6: Go easy on the leverage when yanking, pulling, prying, pushing or jerking on things when working under your vehicle. You might shake it or tip it off its jack stands! The best advice here is to use a pair of jack stands AND a 2T Scissor Jack to support one or both ends of the vehicle. If a support stand slips, hopefully the jack will stop the vehicle from falling any further.
