The ALI (Automotive Lift Institute) is the sponsor of several different ANSI recognized safety requirements for vehicle lifts & the website www.autolift.org, which discusses safety in detail. Yet citing two of these specific references, both Lifting It Right and ANSI-ALIOIM (Automotive Lift Institute Operations Installation and Maintenance) state say to never circumvent a lift manufacturers stated safety warnings & operate the lift in a manner not recommended by that specific manufacturer. In simple English: Don’t use the lift if the manufacturer states not to.
While these safety warnings seem and sound like common sense ideas, many lift buyers and specifiers are ignoring the warnings on the side of a lift and doing what the manufacturer clearly states not to do. Ignoring a manufacturers stated warnings isn’t safe for you, your technicians, & the vehicles being serviced in your garage. Safety warning labels are put on lifts for a specific reason (safety) & ignoring these or circumventing these warnings is just not smart.
Any smart lift buyer, specifier, or lift owner will follow the manufacturers stated warnings and not use the lift in a manner where there is a clear warning to not use the lift.
