Adjusting the Blade Extension

The appropriate blade extension differs depending on the material type and thickness. Before installing the holder in the carriage, turn the holder cap to adjust the blade extension, and then perform trial cutting.




Use the following table to select the appropriate settings according to the material that will be cut.

* Adjust the setting for “Cut Pressure” in the settings screen. For details, see "Settings for Specific Functions".
* Use a high tack adhesive fabric support sheet or a iron-on fabric appliqué contact sheet when you cut a piece of fabric out.
For details, see "Mat and Material Combinations".


The settings indicated in the table are approximations. The setting will differ depending on the type and thickness of the material to be cut. Be sure to perform a trial cutting first.



Appropriate Blade Extension


Adjust the blade extension to slightly exceed the thickness of the material that will be cut. Use the markings on the holder to make the adjustment.

(3) Length of blade tip

Be careful that the blade does not extend too much. The blade can cut even though it only slightly extends from the holder. If too much of the blade extends, it may break.



Adjusting the Cutting Blade


  1. Remove the protective cap.

    After use, be sure to retract the blade into the holder and attach the protective cap.




    Do not allow infants/children to put the protective caps in their mouths.


  2. With the reference line on the holder facing toward you, fully turn the cap to the right to extend the blade tip to its maximum.
