Hello, I am new to this forum. Thanks for letting me participate. I have a Snapper 60375 tiller I have cleaned up and am getting ready to sell. I thought I should go over it and adjust the chain, change the gear box lube, etc... before I sold it. I found a parts manual online. Does anyone know if there is a place to find an operator's manual online so I can see the recommended weight of the gear lube and the proper amount of tension the chain should have?
