how to replace the knife
Knife changing procedures for the Polar 80 and Mohr 80 paper cutters are listed in the machines operations manual. We recommend training by a technician on the procedure prior to attempting on your own. We also find that the majority of our customers choose to have a blade exchange program with us instead of performing their own blade changes. The blade change programs provides a trained technician to replace the blade and check the unit for squareness and accuracy.
