Operation
Before operating, c hec k the fuel and oil lev el, and remo v e debris from the mac hine . Also , ensure that the area is clear of people and debris .
Adding Fuel
In cer tain conditions, gasoline is extr emel y flamma ble and highl y explosi v e. A fir e or explosion fr om gasoline can bur n y ou and other s and can dama ge pr oper ty .
Fill the fuel tank outdoor s, in an open ar ea, when the engine is cold. W ipe up an y gasoline that spills.
Do not fill the fuel tank completel y full. Add gasoline to the fuel tank until the lev el is 1/4 to 1/2 inch (6 to 13 mm) belo w the bottom of the filler neck. T his empty space in the tank allo ws gasoline to expand.
Nev er smok e when handling gasoline, and stay a w ay fr om an open flame or wher e gasoline fumes may be ignited by a spar k.
Stor e gasoline in an appr o v ed container and k eep it out of the r each of childr en. Nev er buy mor e than a 30-day suppl y of gasoline.
Al w ays place gasoline container s on the g r ound a w ay fr om y our v ehicle bef or e filling .
Do not fill gasoline container s inside a v ehicle or on a tr uck or trailer bed because interior car pets or plastic tr uck bed liner s may insulate the container and slo w the loss of an y static charge.
W hen practical, r emo v e gas-po w er ed equipment fr om the tr uck or trailer and r efuel the equipment with its wheels on the g r ound.
If this is not possible, then r efuel such equipment on a tr uck or trailer fr om a por ta ble container , rather than fr om a gasoline dispenser nozzle.
If a gasoline dispenser nozzle must be used, k eep the nozzle in contact with the rim of the fuel tank or container opening at all times until fueling is complete.
12
Use unleaded g asoline (87 pump octane minim um). Leaded, regular g asoline ma y be used if unleaded is not a v ailable .
Important: Do not use methanol, gasoline containing methanol, or gasohol containing mor e than 10% ethanol because the fuel system could be dama ged. Do not mix oil with gasoline.
Checking the Oil Level
Important: T he machine is shipped
without oil in the crankcase. Y ou must fill the crankcase with 20 oz. (0.6 l) of SAE 30 or 10W -30, high quality detergent oil with an API classification of SF , SG , or SH. Sev er e engine dama ge will r esult if y ou attempt to r un it without oil.
Using Stabilizer/Conditioner
