This is a scanned page (MA-9) from a factory service manual's Engine Maintenance section, under the heading "Before Engine Starts (Cont'd)." It covers five maintenance procedures. Replacing the P.C.V. filter requires removing the air cleaner cover and replacing the filter, shown with an illustration of the air cleaner (SMA712A). Checking vapor lines involves visually inspecting for proper attachment, cracks, damage, loose connections, chafing and deterioration, and checking the vacuum relief valve for clogging or sticking (SMA147B). Checking fuel lines (hoses, piping, connections) requires inspecting for loose connections, cracks and deterioration, retightening loose connections, and replacing damaged or deformed parts, with a diagram showing engine, fuel line and fuel tank locations (SMA803A). Replacing the fuel filter requires disconnecting the battery cable, disconnecting the fuel hoses from the filter and replacing it, and plugging the open fuel hoses immediately after removal (SMA521A). Finally, the beginning of the changing engine coolant procedure includes a warning never to change coolant when the engine is hot to avoid scalding, and an instruction to set the heater TEMP control lever fully to the HOT position when replacing coolant. Some text at the bottom of the page is faded and illegible.
