Figure 91. Expansion tank3. If the coolant is low, add a 50/50 mixture of water andethylene glycol antifreeze. Do not use water only oralcohol/methanol base coolants.4. Install the radiator cap and expansion-tank cap.Adding FuelUse only clean, fresh diesel fuel or biodiesel fuels with low(<500 ppm) or ultra low (<15 ppm) sulfur content. Theminimum cetane rating should be 40. Purchase fuel inquantities that can be used within 180 days to ensure fuelfreshness.Fuel tank capacity:79 L (21 US gallons).Use summer grade diesel fuel (No. 2-D) at temperaturesabove -7° C (20° F) and winter grade (No. 1-D or No.1-D/2-D blend) below that temperature. Using winter-gradefuel at lower temperatures provides lower flash point andcold-flow characteristics, which eases starting and reducesplugging of the fuel filter.Using summer-grade fuel above -7° C (20° F) contributestoward longer fuel-pump life and increased power comparedto winter-grade fuel.Important: Do not use kerosene or gasoline instead ofdiesel fuel. Failure to observe this caution will damagethe engine.WARNINGFuel is harmful or fatal if swallowed. Long-termexposure to vapors can cause serious injury andillness.• Avoid prolonged breathing of vapors.• Keep face away from nozzle and gas tank orconditioner opening.• Keep fuel away from eyes and skin.Biodiesel ReadyThis machine can also use a biodiesel blended fuel of upto B20 (20% biodiesel, 80% petrodiesel). The petrodieselportion should be low or ultra low sulfur. Observe thefollowing precautions:• The biodiesel portion of the fuel must meet specificationASTM D6751 or EN14214.• The blended fuel composition should meet ASTM D975or EN590.• Painted surfaces may be damaged by biodiesel blends.• Use B5 (biodiesel content of 5%) or lesser blends in coldweather.• Monitor seals, hoses, gaskets in contact with fuel as theymay degrade over time.• Expect plugging of the fuel filter for a time afterconverting to biodiesel blends.• Contact your distributor for more information aboutbiodiesel fuel.DANGERIn certain conditions, fuel is extremely flammableand highly explosive. A fire or explosion from fuelcan burn you and others and can damage property.• Fill the fuel tank outdoors, in an open area, whenthe engine is cold. Wipe up any fuel that spills.• Never fill the fuel tank inside an enclosed trailer.• Never smoke when handling fuel, and stay awayfrom an open flame or where fuel fumes may beignited by a spark.• Store fuel in an approved container and keep itout of the reach of children. Never buy morethan a 30-day supply of fuel.• Do not operate without entire exhaust system inplace and in proper working condition.23
