Hi Kevin, unfortunately we don't have an Operators/Owners Manual for the Model 590. There are 2 Parts Lists Manuals (One early, One later date). Can you please try my method and let us know how you get on?
Please do not PM me asking for support. Please post your questions in the appropriate forums, as the replies it may receive may help all members, not just the individual member. Kindest Regards, Darryl
