6. MAINTENANCE AND ADJUSTMENTS
6.1 Servicing Knife
6.1.1 Need for Knife Service
The Knife will periodically require servicing when the
Knife Blade
becomes dull. An indication of a
possibly dulling blade may be frequent
messages or ragged cuts on the film edge.
These symptoms should not be confused with problems related to the Knife returning after a completed cut
which can be caused by misalignments.
6.1.2 Operator Knife Service Procedure
Servicing the knife by the operator consists of changing the cutting edge of the knife blade or replacing the
knife blade. The following step-by-step procedure describes the process:

Thumb Nut

marker pen or a grease pencil to mark the
recently dulled edge corner of the blade for
later reference.
5.

ways that four different edges of the blade
can be exposed for cutting. Select a new edge
of the existing blade or if all four edges have
been used, replace the blade with a new one.

Knife Blade
onto the pins on the

careful not to cut yourself!).
7.
