Fuel SafetyDANGERIn certain conditions, fuel is extremelyflammable and highly explosive. A fire orexplosion from fuel can burn you and othersand can damage property.• Fill the fuel tank outdoors, in an open area,when the engine is cold. Wipe up any fuelthat spills.• Never fill the fuel tank inside an enclosedtrailer.• Never smoke when handling fuel, and stayaway from an open flame or where fuelfumes may be ignited by a spark.• Store fuel in an approved container andkeep it out of the reach of children. Neverbuy more than a 180-day supply of fuel.• Do not operate the machine without theentire exhaust system in place and inproper working condition.WARNINGFuel is harmful or fatal if swallowed.Long-term exposure to vapors can causeserious injury and illness.• Avoid prolonged breathing of vapors.• Keep your hands and face away from thenozzle and the fuel-tank opening.• Keep fuel away from your eyes and skin.• Use only an approved fuel container.• Never remove the fuel cap or add fuel to the fueltank while the engine is running.• Never fill containers inside a vehicle or on a truckor trailer bed with a plastic liner. Always placecontainers on the ground and away from yourvehicle before filling.• Remove the equipment from the truck or trailerand add fuel to it while it is on the ground. If thisis not possible, then add fuel using a portablecontainer rather than from a fuel-dispenser nozzle.• Keep the fuel-dispenser nozzle in contact withthe rim of the fuel tank or container opening atall times until fueling is complete. Do not use anozzle lock-open device.• If you spill fuel on your clothing, change yourclothing immediately.• Fill the fuel tank until the fuel level is 25 mm (1inch) below the bottom of the filler neck. Do notoverfill the fuel tank. Replace the fuel-tank capand tighten it securely.Selecting a BladeUsing a Standard-CombinationSail BladeThis blade provides excellent lift and dispersion inalmost any condition. If more or less lift and dischargevelocity is required, consider a different blade.Attributes: It has excellent lift and dispersion in mostconditions.Using an Angled-Sail BladeThe blade generally performs best in lower heights ofcut—1.9 to 6.4 cm (3/4 to 2-1/2 inches).Attributes:• The discharge remains more even at lower heightsof cut.• The discharge has less tendency to throw left andthus leaves a cleaner look around bunkers andfairways.• There is a lower power requirement at lowerheights of cut and in dense turf.Using a High-Lift-Parallel SailBladeThe blade generally performs better in the higherheights of cut—7 to 10 cm (2 to 4 inches).Attributes:• There is more lift and a higher discharge velocity.• Sparse or limp turf is picked up significantly athigher heights of cut.• Wet or sticky clippings are discharged moreefficiently, reducing congestion in the deck.• It requires more horsepower to run.• It tends to discharge further left and tends towindrow at lower heights of cut.WARNINGUsing the high-lift blade with the mulchingbaffle may cause the blade could break,resulting in personal injury or death.Do not use the high-lift blade with themulching baffle.24
