2.4 Adjusting the Blade Length

CAUTION
When handling cutter blades, be careful to avoid cutting your fingers or other parts of
your body.
Make sure that the blade length is suitable for the thickness of the medium being used.
If the blade is extended too far, the writing panel and the blade itself may be damaged.
Adjusting the Blade Length
(1) Before adjusting the blade length, align the blade tip with the tip of the cutter pen by turning the blade
adjustment knob in the B direction (see the figure below).
(2) Next, extend the blade tip to the length suitable for the medium to be used by turning the blade adjust-
ment length in the A direction.
Observe the scale on the plunger cap to determine how far to move the blade.
When the knob is turned the distance of one scale unit, the blade moves 0.1 mm. When it is given one
full turn, the blade moves 0.5 mm.
To extend the blade, turn the knob in the A direction.
To retract the blade, turn it in the B direction.
Obtaining the Correct Blade Length
Assuming that the film thickness is "t", the blade length " " should be equal to "t". Make sure that " " is
never greater than the combined thickness of the film and its backing sheet.
If the film thickness cannot be accurately determined, adjust the blade length by gradually increasing it until
only traces of the blade appear on the backing sheet when a cutting test is executed.
