- For optimal performance, limit continuous operation to 60 minutes.
- Material Compatibility: This tool is suitable for various foam materials including EPS (Expanded Polystyrene), XPS (Extruded Polystyrene), EPE (Expanded Polyethylene), EVA (Ethylene-vinyl acetate), and other foamed plastics. Refer to the full user manual for a detailed density table for cutting materials.
- Power Off: Release the trigger to stop heating. Unplug the tool from the power outlet when finished or when changing blades. Allow the tool and blades to cool completely before storage.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your foam cutter.
- Cleaning Blades: After each use, ensure the tool is unplugged and the blades are cool. Use the provided cleaner tool to gently scrape off any accumulated foam residue from the blades. Do not use abrasive materials or solvents.
- Tool Body: Wipe the tool body with a soft, dry cloth. Do not immerse the tool in water or any other liquid.
- Storage: Store the foam cutter and all accessories in the original storage case in a dry, dust-free environment.
