“So when you search the website for Kohler 12kw maintenance kit be careful i clicked the first thing that popped up and clearly upon further review. This not is for the 12kw generator. And now i have to pay to ship it back and there's going to be a %10 restocking fee. On top of that i have to find a printer to print out the return label on the wing product. Anybody need to buy a 8.5 maintenance kit? Unopened in the box!”

Hi Matt, Thank you for taking the time to share your feedback. We’re sorry to hear about the mix-up with your order. It looks like the incorrect maintenance kit was selected during checkout — our listings specify compatible generator models to help customers choose the right one, but we understand how easy it can be to click the wrong item, especially when products appear similar. Our return policy and restocking fees are standard across all orders, but we’re happy to help make the process as smooth as possible. If you’d like assistance finding the correct 12kW kit or have questions about the return, please don’t hesitate to reach out to us at 855-453-4494 or sales@norwall.com. Regards, Norwall PowerSystems
