At the end of the mowing season, thoroughly clean the mower. Touch up any chipped paint. Wipe exposed metal with a rust-preventing lubricant. Apply a graphite, Teflon or silicone lubricant on throttle and choke cables. Drain the gasoline from the fuel tank (following the manufacturer’s safety precautions). Start the mower and allow it to run until the engine burns all the fuel in the carburetor and fuel lines. Store your mower in a dry location, if possible.
