How to Run a Polar-Mohr Eltromat 72

have you tried Youtube??? seems like everthing is in there...

no video on youtube Labguy, i found a really neat fancy NEW cutter video but nothing on my old guy. Thank you JB those instructions are great so far, i think something may be not working right and your stuff helped alot, i will be back when i have more info, thank you!!

You have the basic operation correct. On thing you need to know about these cutters is that they have a lot of redundant safety features built in.

The light barrier cannot be blocked in any way of it will not cut.

The buttons have to be pushed within about 1/2 second or less of each other or it will not cut.

There are a number of position sensors that must be properly set for it to work as well. The main thing being the light curtain. All 5 of the of the light barrier lights must be calibrated to line up. if they aren't seen by the sensors on the other side no cutting. I am not sure on this model but there is usually a green and red indicator on the left barrier assembly if you don't have a green light then something is not right with the barrier. A burnt bulb or misalignment can cause this as well as something like heavy dust blocking the lenses. (I have also had plenty of pot bellied operators have this be a problem.)

Other thing involved are timing switches relays and a host of other devices that require specific adjustments. One other problem I have come across that created an issue was leveling. The machined must be set perfectly level and the blade carrier must be perfectly perpendicular to the cutting bed. If not binding can occur and it wont cut.

Although Heidelberg does not support these machines any longer you might be able to get a bit of phone assistance from them. If you have anything that might help me diagnose the problem a bit more please post it in this forum. There are a couple of people such as myself on here that have worked with these cutters before.

Alright so we think that that blade is stuck in the half up position and its not moveing at all for that reason.

So my next question is:

Is there a way to manually move the blade into the correct position, or any other option to get it to work while the blade is half down (or half up depending on your outlook :) )?

Excellent description Greg I have just a couple of things to add. You have to tighten the clutch handles into the flywheel real tight to unload the brake or the flywheel will not turn and make sure you run the blade up to top dead center. You can roughly tell this by watching the blade edge. Just before it hits TDC it will make a clicking sound. This is the safety bolt dropping into place. The blade will raise about 1/16th of an inch after that. Make sure you rotate it in the direction of operation, there should be an arrow to indicate rotation direction.

Other than that GA to ya!

Any ideas on progrssively worse problem with no cut cycle starting. All suspect switches replaced. Large vertically mounted Solinoid right rear inconsistent in energizing and deenergizing. Local repairman now says it's the Solinoid thats not easily available. Eltromat 72 # 4551057 in ABQ

yea shut machine off there should be a handle with holes in it for bolts insert the bolts through handle and into fly wheel once in far enough you will be able to roll blade up or down

The safety light curtain is VERY sensitive !

Once our machine wouldn't cut only when the ventilation of the hall was switch on. So : ventilation off -> Polar OK, ventilation on -> no cut.
Finally I found out : when the ventilation was on, a tiny little paper where the operater had written some notes, waved (now and then) just 1 millimeter between the safety light curtain... I kindly asked the operater to stick his little note some place else, and everything worked fine. Ventilation or not.

Thank you all very much, Greg and J B both of those are really helpful, i am going to go try that and i will keep you up to date, and 44m thanks for the warning on the safety curtain, i will certainly check that now and keep it in mind for the future.

Happy to help Katy, If you have any other questions or problems please let me know.

Hello Katy,

It looks like you have hit gold with the answers you are getting! 'gringogreg' and double j b are very good. And I know gringogreg has a 115 cs (I think it is).

Just a thought. Have you tried searching for "Polar Mohr" under 'search all CR4' on the right hand side of the screen? There is quite a lot of Members who have asked for help on your machine and if you have not done so you may find the 'missing link' you need there?I have tried helping a few people with Polar Mohr's.

My first move was trying to get help from the Polar Mohr site........... Do not even try! It seems they are only interested in Sales.

I will keep an eye on your thread as I used to run a Polar Mohr, and I think it was your one, but I cannot recall the type. I know it was the first with "computer control" I think they called it, where you could 'program' the back-gauge.

Take care
