understand the operation of the parts here and we have provided photographs and descriptions but i would like to just start off and say that if you if you look at what the physical layout is it becomes very clear what is happening here in the photographs document very clearly what is happening here has two surfaces it's kind of oblong shape one surface is intended to be down and in contact with what's called the rulers which it's a electrical switch rather small is designed with a flat surface so that when it rotates when it's at either extreme that would push the plunger down and engage the brakes there is a service on the other side as well and behind it there was another range part of the kim obviously room when it was installed one of those design the surface was not supposed to come into play at all and when it was installed upside down this resulted in a strange operation of this with the world home would not always contact the surface rubber roller and the cam service which is what was intended when that happened that change where the debris engaged at the lower end of this because this was not undergone a lot of modification of the machine that would have solved the manufacture of my bill not only was it not something that didn't modif very many companies just like with automobiles that are not actually manufacturers representatives who work sell these machines and work on these machines the machine was serviced by  these new specificities are in the service and there has never been a service manual for this machine produced the representative of you heinrich testified got his information from a manual for a different machine which was similar but it was not the same machine it was a different machine and his other information as he thought id got by making a phone call to germany and asking other people because he wasn't there at the time he didn't have the records known hasn't been able to find the records of the actual sale of this machine so his opinions  matter what service person it was or when it was done before the yes obviously from the record it was clear that cam had been in both positions and had been  supposed to function the other we don't know what it was but it wasn't the one that was designed to fall for it was just gonna stop it you lose it or not it could rotate built well they designed this machine with a hammer that was critical to the safety and operation of the machine it was a safety device it was cr identifies this or identifies the necessity of the alignment and that it is someone who's working on the machine a way of ascertaining the line there's no mark there's no stick or not hi right and what would happen is they would say it seems to be working fine because when you would go use it you knew it was going on you'd be gone long if you pulled it up high enough it's it's not going to come into play you know they couldn't recreate the condition and that's what made it so dangerous it was the consistent you could you could be going on like the plane was and it would stop suddenly right without moving it up and down other times you know they don't have protractors they don't know what the they didn't design him in a way that would ensure that work properly and it was able to be easily position so that would not for ages talking about what it is to be a modified machine and they were they created this test and it's not they didn't do this at the trial court this is new case law that they came up with according to the routes it where it's from fifteen to twenty five as opposed to fifteen to thirty four so what he did was it actually extended the operational era where it fixed position he did not remember anything about how this work and how adjustments were made when you look at his testimony about previously when he tried to change the subject as he talks about adjusting the switch it's not like a sophomore or it's hard to stop so sometimes that will stop when you're here and sometimes will stop when you're there and you never know until you actually encounter where it's going to stop and if you started off of the stock or the first service manual nobody knows where it is or what the service manual for this but here was the operators manual was not on the machine and available for the people you got things the response to do on a daily basis to
