Retainer Cover, AIR Cleaner, Clean Engine

Your four-cycle engine will normally consume some oil; therefore, check engine oil level regularly--

approximately every five hours of operation and before each usage. Stop engine and wait several minutes before checking oil level. With engine level, the oil must be to the FULL mark on dipstick (refer to figure 11). Change engine oil after the first five hours of operation, and every twenty-five hours thereafter.
