Recommended Gasoline

Use UNLEADED R egular Gasoline suitable for automoti v e use (85 pump octane minim um). Leaded regular g asoline ma y be used if unleaded regular is not a v ailable .

Important: Nev er 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.

Gasoline is har mful or f atal if s w allo w ed. Long-ter m exposur e to v apor s can cause serious injur y and illness.

• A v oid pr olonged br eathing of v apor s.

• K eep f ace a w ay fr om nozzle and gas tank or

conditioner opening .

• K eep gas a w ay fr om ey es and skin.

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.

• Nev er ﬁll the fuel tank inside an enclosed

trailer .

• 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.

Using Stabilizer/Conditioner

Use a fuel stabilizer/conditioner in the mac hine to pro vide the follo wing beneﬁts:

• K ee ps g asoline fresh during storag e of 90 da ys or

less . F or long er storag e it is recommended that the fuel tank be drained.

Page 20

• Cleans the engine while it r uns

• Eliminates gum-lik e v ar nish buildup in the fuel

system, whic h causes hard star ting

Important: Do not use fuel additi v es containing methanol or ethanol.

Add the cor rect amount of g as stabilizer/conditioner to the g as .

Note: A fuel stabilizer/conditioner is most effecti v e when mix ed with fresh g asoline . T o minimize the c hance of v ar nish de posits in the fuel system, use fuel stabilizer at all times .

Filling the Fuel Tank

1. Shut the engine off and set the parking brak e .

2. Clean around fuel tank cap and remo v e the cap . Add unleaded regular g asoline to fuel tank, until the lev el is 1/4 to 1/2 inc h (6 to 13 mm) belo w the bottom of the ﬁller nec k. T his space in the tank allo ws g asoline to expand. Do not ﬁll the fuel tank completely full.

3. Install fuel tank cap securely . Wipe up any g asoline that ma y ha v e spilled.
