polar mohr cutter

Don't know how old this is. We use it all the time. For sale. It is leaking Gear Oil. We are in Victoria Canada. We require a written offer. Photos on Drop Box. We may be able to generate a video.

Today we changed the blade of our Polar Mohr 92EM. After setting up the blades. We cut the paper and after sometimes when we going to make the first cut the blade stops before cutting and then we get error code 85. It happened first time only. Any help with resolving this would be greatly...
