When using optional accessories, always take into account the length of the blade fixed in the holders of the platforms and choose/adjust the correct blade heating cycle. To do this, follow these steps:
1) Set the step-by-step power controller to the minimum value.
2) Fix the blade to the platform holders.
3) Activate the cutter by holding down the power button (switch)
4) Touch the material with the blade.
5) Turn the step-by-step power controller until the blade starts to cut the material smoothly.
Note that it takes 3 to 5 seconds for the blade to heat to the value set on the controller.
6) When the right value is set, you can now start working.

NB! Do not use the maximum power without the need for a long time. This can lead to strong cutting blade deformation or HWS250! breakage.
