Gasoline vapor can build up inside the fuel tank creating pressure. This pressure may
increase when the engine is hot from running. Opening the fuel tank under pressure can
cause rapid escape of flammable vapors and possible fuel spills that may ignite from
contact with hot engine surfaces resulting in burn hazard. To avoid rapidly escaping fuel
vapor, always allow the engine to cool for at least two (2) minutes before removing fuel
cap and loosen the fuel cap slowly to relieve any pressure in the tank.

REFUELING
Gasoline is highly flammable and gasoline vapors are extremely explosive. Fire and
explosions can cause severe burns and/or death. Keep gasoline away from flames,
sparks, and other ignition sources. Refuel outdoors in a well-ventilated area with the
engine stopped and cool. Wipe up any spilled gasoline and allow engine to dry before
starting. Keep a fire extinguisher handy while refueling. Do not operate engine with leaks
in the fuel system. Do not store gasoline near other flammable materials.
Old gasoline can create deposits that clog fuel systems causing hard starting and poor
performance. Damage caused by old fuel is not covered by warranty. To minimize
deposits, avoid old fuel related performance issues, and prevent costly repair work, do
not use gasoline that is older than 30 days.
OLD FUEL
Using gasoline with an alcohol blend greater than 10% (E10) will damage the engine.
Damage caused by using an alcohol blend of 15% (E15), 85% (E85), or any other alcohol
blend higher than 10% (E10) is not covered under warranty. To avoid engine damage
caused by an alcohol blend that is too high, use gasoline with 10% (E10) alcohol or less.
ALCOHOL BLENDS
The use of fuel system cleaning additives can damage the engine and fuel systems.
Damage caused by the use of fuel system cleaning additives is not covered by warranty.
To avoid engine and fuel system damage, do not use any fuel system cleaning additives.
