Contact your Authorized Service Dealer orDistributor or go to www.Toro.com for a list of all approvedattachments and accessories.OperationNote: Determine the left and right sides of the machinefrom the normal operating position.CAUTIONThis machine produces sound levels in excess of 80dBA at the operators ear and can cause hearing lossthrough extended periods of exposure.Wear hearing protection when operating thismachine.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: 51.1 liters (13.5 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. Use of winter gradefuel at lower temperatures provides lower flash point andcold flow characteristics which will ease starting and reducefuel filter plugging.Use of summer grade fuel above -7° C (20° F) will contributetoward 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 fuel 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.19
