The importance of maintaining the proper oil level cannot be overemphasized. Inspecting the Oil Level Window 1. Stop the engine and allow it to cool. 2. Set the unit on a flat, level surface, such as a workbench or table. The cutting head shield should hang over the edge so that the engine is level (Fig. 11). NOTE: Failure to keep the engine level may cause the oil to overfill. 3. Look into the oil level window; use a flashlight if necessary. The oil level should fill the window approximately halfway (Fig. 12). If the oil level is too low, add oil. Refer to Adding Oil. Adding Oil 1. Clean the area around the oil fill plug (Fig. 12) to prevent debris from entering the oil fill hole. 2. Unscrew the oil fill plug. 3. Add oil to the oil fill hole until the oil level is approximately halfway up the oil level window (Fig. 12). NOTE: DO NOT overfill the crankcase. 4. Wipe up any oil that may have spilled. 5. Reinstall the oil fill plug. NOTE: Make sure the O-ring is in place on the oil fill plug (Fig. 12). 11 Oil Fill Plug Oil Fill Hole Maximum Oil Level Fig. 11 Fig. 12 O-Ring
