I am trying to use an older model of a FeatherLite trimmer used by my late father who didn't get the chance to teach me haw to use it. Do you still have the manual available for: Weed Eater FeatherLite XT25 Plus made by Fridgidaire Home Products. I have no idea how old it is but it was barely used. It is the petrol model by the way. I hope you can help me as the weeds are nearly up to my knees!!! Regards, Terry Brown
