Heidelberg SM72 FP, Intermittent Main Motor Issue

[marg_lucas]

We have a Heidelberg SM72 FP ,1986 that starts normally but after 4 to 5 hours of running the motor stops and needs to be manually restarted using a handle on the machine
Has anyone come across this issue before? What could be the problem? Could it be major?
The machine is in a tight space so access to the motor is restricted.

Your assistance will be greatly appreciated
Thanks

Thanks for the quick reply . The machine is a 1986. There is a handle that is used to re start the machine.

Kind regards

Any error codes?
What does the screen say?

"Handle on the machine", meaning the main motor brake handle? If that's so, you have a brake disc problem, or best case, the switch on the brake requires readjustment or replacement.

There are no error codes. An engineer checked it and thought it was the clutch (that needed replacement
