looking for documents for an Aqua fresh extractor

[Seastar]

I'm considering purchasing a carpet extractor which is a discontinued model of an Aqua Fresh . It's a ten gallon...probably not used very much at all. It was stored in a barn..It is a 1998 model...everything works on it but having diffulty getting the sprayer to operate..First time I started it it did one good sweep..then the sprayer stopped...Any sugestions on finding a manuel or trouble shooting...Would be a great enhancement to my biz...Thanks Sea
