Q&A

Maintenance Tips

• Clean exterior shell: Use mild soap + water; avoid solvents that can weaken the roto-molded plastic.
• Latch & seal care: Keep gasket and front/rear lids free of dust to maintain tight closure and dust resistance.
• Wheel maintenance: Clean integrated rear wheels after transport; remove grit for smooth rolling.
• Handle check: Ensure 1-touch pull handle locks securely; tighten mounting hardware if any looseness develops.
• Rack rail inspection: Periodically verify rack screws/rails to prevent vibration loosening during travel.
• Vent/pressure check: Keep any pressure equalization features clear for smooth lid operation.
• Impact inspection: Check corners and edges after heavy travel for stress marks or cracks.
• Storage: Store upright in a cool, dry place away from direct sunlight to reduce UV wear and warping risk.
