I am just finishing a total rebuild of a used and abused l4530b hoe and I need some info since I don't have a manual for it. First is what hdy. oil is recommended and what is the quantity required? Also I would like to know if the toplink goes in the top hole or does it not matter. Also is there a proper method of adjusting the toplink, with the weight of the hoe hanging or should the weight be off (released)? That's all for now I think. Thanks for any help. This is also the same as a Woods BH750-2.
