Problem with Wohlenberg 137 cutter

Our company has a mid 2000's Wohlenberg 137 cutter. We have had this issue for almost as long as we owned the cutter. It will work fine for long periods of time then out of nowhere it just stops cutting when the cut buttons are pushed. You push the buttons over and over and nothing happens. Eventually some times as much as 5 or 10 times of pressing the buttons it will make a cut. The cutter will act up like this sometimes for 1 hour or up to a day. Then out of nowhere it just starts working again. We have cleaned the cut buttons, tightened up the lock nuts that hold the buttons on. I have completely removed the switches that activate the blade cleaned them and reinstalled with no success. We have tried resetting the cutter again with no success. Has anyone had a similar issue and if so where you able to resolve it.

If you have a multimeter handy, can you check if you have continuity through the buttons when they are pushed? Do this several times to make sure the buttons aren't the culprit. If they are fine, the next thing to check would be the wires leading from the buttons to wherever they go. Check for continuity from the buttons all the way thru the wires they terminate to. Faulty wiring can cause this issue. If everything looks good, your next step would be to check whatever circuit registers your cut buttons.

On our Polar 76 em, our cut buttons light up LEDs on a circuit board inside our cutter corresponding to which button is pressed. I'm not sure if this cutter has the same setup.
