[. . . ] To keep your engine in top operating condition, follow the maintenance procedures in this manual. To ensure safe operation please read the following statements and understand their meaning. Also refer to your equipment owner's manual for other important safety information. This manual contains safety precautions which are explained below. WARNING Warning is used to indicate the presence of a hazard that can cause severe personal injury, death, or substantial property damage if the warning is ignored. [. . . ] Annually or every 300 hours of operation (more often under extremely dusty or dirty conditions), replace the paper element and check the inner element. Unhook the two retaining clips on each end and remove the end caps from the air cleaner housing. See Figure 1. Service Oil Cooler Some engines are equipped with an optional oil cooler. Inspect and clean oil cooler every 100 hours of operation (more frequently under severe conditions). To service the oil cooler, clean the outside of fins with a brush. Remove the hardware holding the cooler unit to the blower housing. Clean the inside of the cooler with a brush. After cleaning, reinstall the oil cooler to the blower housing with the mounting hardware. 9 2. Pull the air cleaner paper element out of the housing on opposite side. See Figures 9 and 10. Ejector Area Inlet Screen Figure 9. Install the new inner element, followed by the paper element. Replace the plug if worn or reuse is questionable. NOTE: Do not clean the spark plug in a machine using abrasive grit. Some grit could remain in the spark plug and enter the engine causing extensive wear and damage. Check the gap using a wire feeler gauge. Adjust the gap to 0. 76 mm (0. 030 in. ) by carefully bending the ground electrode. Wire Gauge Spark Plug Fuel System High Pressure Fluids can puncture skin and cause severe injury or death. Do not work on fuel system without proper training and safety equipment. WARNING General The precision components inside the fuel pump module are not serviceable. DO NOT attempt to open the fuel pump module. Damage to the components will result and the warranty will be void. Because the fuel pump module is not serviceable, the engines are equipped with a special 10-micron EFI fuel filter to prevent harmful contamination from entering the module. If there are two filters in the system, the one before the lift pump will be a standard 51-75 micron filter, and the one after the lift pump will be the special 10-micron filter. Be sure to use an approved 10-micron filter for replacement. [. . . ] (b) (c) Be aware, however, that Kohler Co. may deny warranty coverage if the engine or a part has failed due to abuse, neglect, improper maintenance or unapproved modifications. For warranty repairs, the engine must be presented to a Kohler Co. service center as soon as a problem exists. [. . . ]
