1.4.2 Changing the Knife Blade
The knife blade should be replaced when the force has been increased by more than 20 percent
of the original cut force or the cut quality has degraded. The rst sign of blade degradation usually
occurs in the corners of the cut and may lead to poor weeding.
1. Remove the used blade
a) Loosen the brass thumbscrew on the carriage tool block and remove the knife holder assembly.
b) Unscrew the black tip of the Knife Holder assembly.
c) Carefully (blade will be sharp, use caution) remove the blade from the knife holder
assembly.
d) Discard the blade safely.
2. Insert a new blade
a) Take out a new blade from its plastic case and remove the protective latex cap. Cap color
indicates blade angle (Red = 45º blade, Green = 60º blade, Blue = 30º Blade). 30º is the
most commonly used label application
b) Carefully insert the new blade into the holder assembly.
c) adjust the black cap to obtain
desired blade depth.
3. Reinstall the Knife Holder
Assembly in the tool block on the
cutter carriage.
a) Ensure that the shoulder of
the assembly is seated ush
with the top of the tool block.

the tool block to keep the
knife holder in place.
