REV A 4-4 605046
Fuel and Evaporative Emissions Control
System
The fuel and evaporative emissions control system for this
mower is EPA compliant. Use only BigDog
®
Mowers approved
replacement parts.
Your evaporative emission control system may include parts
such as: fuel tanks, fuel lines, fuel line fittings, fuel caps, carbon
canisters, canister mounting brackets, carburetor purge port
connection, filters, vapor hoses, clamps, control valves, control
solenoids, electronic controls, vacuum control diaphragms,
purge valves, liquid/vapor separator and other associated
components.
Modifying or Tampering with the evaporative emissions
control system or the fuel system is prohibited. Federal law
and California State law prohibit the following acts or the
causing thereof:
1. The removal or rendering inoperative by any person other
than for purposes of maintenance, repair, replacement, of
any device or element of design incorporated into any
equipment for the purposes of emissions control prior to
or after its sales or delivery to the ultimate purchaser or
while it is in use, or
2. The use of the equipment after such device or element of
design has been removed or rendered inoperative by any
person.
The fuel tank is located under the seat platform with the filler
neck and fuel cap located in the left side fender. Figure 4-4
Remove the fuel cap slowly.
When threading the fuel cap onto the filler neck, tighten the
cap until it begins to click, then, continue to turn it until at least
three clicks are heard.
IMPORTANT: Do not overfill the fuel tank. The fuel tank
should be filled no higher than the bottom of the fill neck.
Use of replacement parts not equivalent to the original
parts may result in system failure and pose a safety haz-
ard.
To avoid personal injury or property damage, use
extreme care in handling fuel. Fuel is extremely flam-
mable and the vapors are explosive.
Observe usual fuel handling precautions
• Do not smoke while refueling. Extinguish all ciga-
rettes, cigars, pipes and other sources of ignition.
• Do not remove fuel cap or fill tank with engine
running or while engine is hot. Clean up any fuel
spills.
• If fuel is spilled, do not attempt to start the engine
but move the machine away from the area of spill-
age and avoid creating any source of ignition until
fuel vapors have dissipated.
• Allow engine to cool before storing machine inside
a building.
• Keep fuel away from open flame or spark and store
machine away from open flame or spark or pilot
light such as on a water heater or appliances.
• Use extreme care when handling gasoline and other
fuels. They are extremely flammable and vapors are
explosive. A fire or explosion from fuel can burn
you and others and can damage property.
• Refuel outdoors. Never refuel or drain the fuel from
the machine indoors.
• Never attempt to start engine when there is a strong
odor of gasoline fumes present. Locate and correct
cause.
• Store fuel in an approved container and keep it out
of the reach of children. Never buy more than a 30
day supply of fuel.
• Do not fill fuel containers inside a vehicle or on a
truck or trailer bed with interior carpets or plastic
truck bed liners. Always place fuel containers on
the ground away from your vehicle before filling.
• When practical, remove gas powered equipment
from the truck or trailer and refuel the equipment
with its wheels on the ground. If this is not possible,
then refuel such equipment on the truck or trailer
using a portable container and not a fuel dispenser
nozzle. If a fuel dispenser nozzle must be used,
keep the nozzle in contact with the rim of the fuel
tank or container opening at all times until fueling is
complete. Do not use a nozzle lock-open device.
• Never use gasoline for cleaning parts.
• Read and observe safety precautions elsewhere in
this manual.
• Gasoline is harmful or fatal if swallowed.
• Long-term exposure to vapors can cause serious
injury and illness.
• Avoid prolonged breathing of vapors.
• Keep face away from nozzle and gas tank or fuel
container opening.
• Keep gas away from eyes and skin.
• If fuel is spilled on clothing, change clothing imme-
diately.
