The standard upper knife made of tool steel is marked “A“. This type of knife can be also purchased as a

type made of sintered carbide for a longer service life. To cut very small radiuses, it is possible to use a

knife of the “B“ type; and for thin and soft materials it is possible to order the “C“ type. With the latter two

knives it is necessary to reduce the trimming mechanism lifting (Service manual, section 8.2) to the value

given in the table; it is necessary to adjust their correct height again (Service manual, section 8.3).

The supplied knives can be sharpened again after they have gone blunt, either by means of a special

manual fixture M269 (may be ordered additionally), or on a bracket of a special grinding machine,

observing the prescribed geometry (Service manual, section 8.8).
