Adjusting the Blade Length
CAUTION
• To avoid cutting your fingers, always handle the cutter blade with caution.
• If the blade is extended too far in relation to the thickness of the film being cut, it will
damage the cutting mat. Be sure to properly adjust the blade length.
Step 1
Adjust the blade length by turning the blade length adjustment knob as shown
in the figure below. Turn the knob in the “A” direction to extend the blade, or
in the “B” direction to extract the blade. Refer to the scale on the plunger mark
to determine how far to move the blade. When the knob is turned the distance
of one scale unit, the blade moves about 0.1 mm. A full turn of the knob moves
the blade about 0.5 mm.
Step 2
First of all, align the blade’s tip with the tip of the cutter pen. From that position, extend the blade to
suit the thickness of film to be cut.
Step 3
Assuming that the film’s thickness is “t”, the blade length “ ”
should be equal to or slightly greater than “t”. Be sure that “ ”
is never greater than the combined thickness of the film and
its backing sheet.
If you cannot accurately determine the film’s thickness, adjust
the blade length by gradually increasing it until only traces of
the blade appear on the backing sheet as a result of running
a cutting test.
