Polar 76 em error

[bharatmacho]

Can any body provide solution for polar 76 em cutting machine error. the error code is 59

i think it is the backguage limit switch error.
try replacing it. is the back guage in the middle of the table or far at the back?

[bharatmacho]

the back gauge is at the middle. but in the manual it was given for error 59= replace card AR.

I am not saying this is the problem but has your cable been changed? I have found backgage errors appear because the cable running from the machine to the backgage has gone back and forth so many times it breaks a connection someplace. I have replaced two cables on ours. Lots of years and lots of cutting.
