Pretrip Inspection and Daily Maintenance pump, causing sudden loss of engine power, possi- bly resulting in serious personal injury due to re- duced vehicle control. WARNING 18. Check the fuel level in the tank(s) and be sure the fuel cap vent area is clean. Check the fuel/water separator, if equipped, for leaks, and if needed, prime the fuel tank system. Do not mix gasoline or alcohol with diesel fuel. This mixture could cause an explosion. When filling fuel tanks, do not smoke or use an open flame near the fuel tanks. Combustion of diesel fuel oil or fuel va- pors could result, possibly causing personal injury or property damage.
WARNING 18.2 Always strain or filter fuel before filling it into the tanks. This will lengthen the life of the engine fuel filter and reduce the chances of dirt entering the engine. Never fill fuel tanks to more than 95 percent of their liquid capacity. This could make them more likely to rupture from impact, possibly causing fire and re- sulting in serious personal injury or death by burn- ing. 18.3 Before installing the fuel cap, check the vent line for debris. Clean the area around the fuel tank cap with a rag, or if necessary, clean the cap with solvent. IMPORTANT: Use only low-sulfur diesel fuels.
Low-sulfur diesel fuels have a maximum 0.05 percent sulfur content compared to a 0.26 to 0.30 percent sulfur content. Failure to use low- sulfur diesel fuels may void the warranty on emission components. CAUTION Don’t crank the engine for more than 30 seconds at a time during any of the following procedures. Wait two minutes after each try to allow the starter to cool. Failure to do so could cause starter damage. 18.1 To keep condensation to a minimum, fill the fuel tanks at the end of each day, but not to more than 95 percent of liquid capacity. Se- lect the proper grade of fuel as specified by the engine manufacturer. IMPORTANT:
