GASOLINE SPECIFICATIONS
SPECIFICATIONS & INFORMATION
GASOLINE SPECIFICATIONS
IMPORTANT: To avoid engine damage:
• DO NOT mix oil with gasoline
• Use only clean oil and fuel
• Use clean approved containers and funnels.
• Store oil and fuel in an area protected from dust,
moisture and other contamination.
Unleaded fuel is recommended because it burns
cleaner and leaves less unburned deposits in engine
combustion chamber. Regular unleaded gasoline with
an anti-knock index of 85 octane or higher may be
used. Use of gasohol is acceptable as long as the ethyl
alcohol blend does not exceed 11 percent. Do not use
gasoline that contains Methanol.
Fill fuel tank at end of each day's operation. Fill only to
bottom of filler neck
.
GASOLINE STORAGE
Keep fuel in a clean container in a protected area. Do
not use deicers to remove water from fuel. Do not
depend on fuel filters to remove water.
If possible, install a water separator at the storage tank
outlet.
IMPORTANT: Keep all dirt, scale, water or other
foreign material out of fuel.
If mower is stored for the winter, add gasoline storage
stabilizer to the fuel. Follow directions on can.
LUBRICANT SPECIFICATIONS
ENGINE OIL
Use oil viscosity based on the expected air temperature
range during the period between oil changes.
The following oil is preferred:
• 10W30
Other oils may be used if they meet one of the
following:
• API Service Classification SG
• API Service Classification SF
• CCMC Specification G4
Oils meeting Military Specification MIL-L-46167B may
be used as arctic oils.
ENGINE BREAK–IN OIL
IMPORTANT: ONLY use a quality break-in oil in
rebuilt or remanufactured engines for the first 5
hours (maximum) of operation. DO NOT use oils
with heavier viscosity weights than SAE 5W-30
or oils meeting specifications API SG, SH; or
oils meeting CCMC Specification G5. These oils
will not allow rebuilt or remanufactured engines
to break-in properly.
CAUTION
Handle fuel with care, it is highly flammable. DO
NOT refuel machine:
• Indoors. Always fill fuel tank outdoors.
• While you smoke.
• When machine is near and open flame or
sparks.
• When engine is running. STOP engine.
• When engine is hot. Allow it to cool.
Help prevent fires:
• Fill fuel tank only to bottom of filler neck.
• Clean oil, grease and dirt from machine.
• Clean up spilled fuel immediately.
• Do not store machine with fuel in tank in a
building where fumes may reach an open
flame or spark.
To prevent fire and explosion caused by static
electric discharge while you fill tank:
• Use approved, non-metal fuel container.
• When using a funnel, MAKE SURE it is
PLASTIC.
• Avoid using a funnel which has a metal screen
