couldnt get the top deck to come down on my decker today , tried everything but no good[ night lad had problems last night , but eventually got it to go.
so rang in and fitter came out, shows him the problem and he said the computers not telling the failsafe bars to go back into place , so he jumps up in back , hits them back with his HANDS 
, then down it commes alright
so he says thats all you do, now i said im not going under that deck and hitting them bars back by hand because once youve hit the last one back theres nothing in theory to stop that deck flattening you if whatever holds it up [hydraulics i guess] fail, but fitter says it will not come down , if hes right , whats the point of those failsafe bars 
all sounds dodgy to me , or am i worrying to much.
n.b explained this to night shift lad and he said fitter will be comming out to hit the bars back as like me he not going under deck
