the head pump is harder to pump
My wife is complaining the head is harder to pump this year. She said last year the metal piece under the handle had grease on it but this year it does not. Is there some kind of lubricate to use? I did not want to useany old grease because I an heard it can be harmful to plastic/seals. What do you put on the metal rod that slides in and out as you pull the handle up and down.
