5.2. Cutting Foam
- Prepare Workpiece: Place the foam material on a stable, heat-resistant surface.
- Guide the Tool: Once the blade is hot, gently guide the tool through the foam material with ease. Apply steady, light pressure. The hot wire will melt through the foam, producing clean, precise cuts every time.
- Using Sled and Ruler: For straight and precise cuts, attach the sled and ruler accessory. This allows you to maintain a consistent cutting depth and angle.

5.3. Important Considerations
- Do not force the tool through the foam. Let the heat do the work.
- Avoid prolonged contact with a single spot to prevent excessive melting or burning.
- Always ensure the area is well-ventilated to disperse any fumes.
6. Maintenance
Proper maintenance ensures the longevity and performance of your foam cutter:
- Cleaning the Blade: After use, allow the blade to cool completely. Use the included brush to gently remove any melted foam residue from the blade and cutting wire. Do not use abrasive cleaners or solvents.
- Storage: Always store the foam cutter and its accessories in the provided blue plastic case. This protects the components from dust, damage, and keeps them organized. Store in a dry place away from direct sunlight and extreme temperatures.
- Cord Care: Inspect the power cord regularly for any signs of damage. Do not use the tool if the cord is frayed or damaged.
