Warranty Backed by Ko-ken USA
-
U.S.-Based Support: Warranty coverage is offered and funded directly by Ko-ken USA, not by the manufacturer in Japan.
-
Local Management: All warranty services are handled through our U.S. operations to provide fast, reliable assistance tailored to our market.
Why Only Authorized Purchases Qualify
-
Authorized Network Only: We can only provide warranty coverage for tools purchased through our approved North American dealers and distributors.
-
Unsupported Channels: Tools purchased outside of this network—including from unauthorized sellers or international sources—are not eligible for warranty support.
-
Sustainability of Service: As our warranty resources are limited to our regional operations, we are unable to absorb the cost of replacements for items not sold through our official channels.
Our Recommendation
To receive full product support, including warranty coverage, always purchase Ko-ken tools through authorized North American dealers. This ensures you benefit from the complete service and support structure we’ve built for our customers.
We appreciate your understanding and thank you for choosing Ko-ken tools.
