I know this is going to be pretty generic and vague, just looking for info from others....Got a new customer that has a few newer Otis Gen 2 cars, looking for us to maintain them. Customer purchased the Otis tool for the cars. I think one of them has had a few issues, nothing serious from my understanding. Just wanted to get some opinions or general info from others who have some on route... knowing they have the tool for the cars will that be enough in most cases? is there any other concerns we need to consider taking these over. Obviously we are not Otis, just a small shop but trying to get some of the proprietary stuff on contract. thanks for any help
