Thanks for the response.

It's a passenger lift.

The operating permit has expired because the elevator stopped working so we let the permit lapse.

We had a qualified Union Elevator Company servicing the elevator but the contract is not in place at the present time. We had them out about a year ago to have a look but after a couple of hours and $1000, they were unable to solve the issue ( which I described in the previous post) so we decided to put the work on hold.

The original hydraulics were replaced at some point.

Also FYI, we were in discussions with the city re grandfathering certain current requirements. The discussion was also placed on hold when the elevator quit working.

I believe that someone with knowledge of how the system works and the drawings will be able to correct the issue so that is actually what I am looking for.
