Frequently Asked Questions

Q: What makes air-cooling better than liquid cooling for my application?

A: Air-cooling eliminates leak risks in remote or rugged environments. You avoid water pumps, hoses, and thermostats that create failure points. Maintenance becomes simpler and more cost-effective over the engine's lifetime.

Q: Can this engine operate in extreme temperatures?

A: Yes. The air-cooled design prevents freezing issues in cold climates and boiling problems in hot conditions. High-surface-area aluminum fins dissipate heat effectively across temperature ranges.

Q: What's included in the 1-year warranty?

A: Our warranty covers manufacturing defects and material failures. Global local agents provide service support. You receive responsive assistance throughout the warranty period.

Q: How quickly can I receive a custom order?

A: Standard inventory ships immediately from our 100-unit stock. Custom orders (1-10 units) complete within 20 days. Larger customizations receive dedicated project timelines.

Q: What maintenance does this engine require?

A: Regular maintenance includes spark plug inspection, air filter cleaning, and proper fuel-oil mixture at 25:1 ratio. The simple structure means fewer components to service compared to liquid-cooled alternatives.

Q: Is technical documentation available in my language?

A: We provide comprehensive technical manuals and support materials. Our global agent network offers localized assistance in multiple languages.
