As with any product, it should be expected that component parts - particularly moving parts, seals, o-rings, wheels, hose, and connectors- will wear with use and over time, and eventually may need to be replaced or refurbished. This type of normal wear and tear is naturally not covered by our guarantee, but we will always be happy to provide you with prompt, high quality service and replacement parts at a nominal cost.This warranty gives you specific legal rights, and you may also have other rights which vary from state to state. (Some states do not allow the exclusion or limitation of incidental or consequential damages, so the above limitation may not apply to you.) You will find that we apply the same standard of excellence to our customer service as we do to our products.
