Blade Resharpening
Please note: A dull knife does not cut accurately. The cutting of thicker stock paper or cardboard, will blunt the
blade easily. When the knife cannot cut the paper pile cleanly even when the cutting stick has been changed and
the knife adjustment has been done, then the blade is required to be resharpened. When you need to resharpen
the blade, take the blade to be resharpened and then refer to the ‘Blade Replacement’ section for instructions on
how to reload the blade.
Precise cuts are only possible with a sharp knife. The knife should be changed as soon as the quality and the
accuracy of the cuts are not to the expected standards. If the knife should jam in the paper pile or leave grooves
in the paper, the knife must be changed right away. Knife life with basic paper is approximately 600 cutting times,
depending on the cutting capacity. This will vary depending on the paper stock being cut. The knife should only
be changed by a single person, to avoid injuries. The cutting edge is extremely sharp and must be handled with
care.
NOTE: Please refer to the following sections of the manual for ‘Blade Replacement’
