PURPOSE: A lift is provided to efficiently remove waste oil when oil is replaced in a vehicle. CONSTITUTION: An oil replacement device efficiently removes waste oil by tilting a vehicle to the drain plug of an oil pan. The oil replacement device comprises two supports installing hydraulic cylinders. While oil is replaced, one hydraulic cylinder is operated to tilt the vehicle and after the replacement, the other hydraulic cylinder is operated to return the vehicle back. The tilting degree is less than 30 degrees for safety and a link balances the supporting face of tires regardless of the tilting degree. |
