5.5 Knife Blade Cleaning
Occasionally knife blades will become dirty from buildup of coated tapes
affecting knife performance. This may cause material to loop between the
feed and knife mechanisms. In order to restore knife to original operating
condition build up on blades must be removed.
• Coatings will build up at different number of cuts depending on
material being cut.
• Coatings that are thicker and softer may require more frequent
cleaning.
