2 post lift install -- documented
The three main “don’ts” I remember are 1) don’t stop it without the lock engaged, 2) don’t bypass the locks on the arms and 3) don’t raise a vehicle from one end using only one arm.
These all seem obvious, but he said people do it all the time. I never even thought of that last one. He said they were called out to remove a lift that failed because the shop was doing that, and when they moved the vehicle there was a bloody mess.
