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.

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.
Using Stabilizer/Conditioner
Use a fuel stabilizer/conditioner in the traction
unit 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.
•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. P ark the mac hine on a lev el surface and stop
the engine .
2. Allo w the engine to cool.
3. Clean around the fuel tank cap and remo v e it.
4. Add unleaded g asoline to the fuel tank, until
the lev el is 1 inc h (26 mm) belo w the bottom
of the filler nec k.
Important: T his space in the tank allo ws
gasoline to expand. Do not fill the fuel
tank completel y full.
5. Install the fuel tank cap securely .
6. Wipe up any g asoline that ma y ha v e spilled.
Checking the Oil Level
