I needed additional help with leaves as this fall I had a very hard time cleaning them up. Luckily I have a very good spot to dispose of them. My Dr Leaf Vac didn't cut the mustard as I had to empty it 7 or 8 times per day, when trying to get rid of them. So I shopped around for a good Billy Goat Blower. I purchase a Billy Goat leaf blower F1402V (14HP Vanguard engine) in good condition. After checking it doesn't look like it had a lot of maintenance. The engine oil level was on the low mark of the dip stick. This indication sent me to the local Auto store for engine oil, and gear oil, spark plug. I have downloaded numerous PFD's from Billy goat for Owners manual. Not one show how and where to put fluids. The only one I can figure out is engine oil. Billy goat claims I need 32 oz of gear oil, but the fill and drain I cannot find. This is the push blower, not a self propelled model.
