Oil and Fuel
POTENTIAL HAZARD
In certain conditions gasoline is extremely
flammable and highly explosive.
WHAT CAN HAPPEN
A fire or explosion from gasoline can burn you,
others, and cause property damage.
HOW TO AVOID THE HAZARD
Use a funnel and fill the fuel tank outdoors, in
an open area, when the engine is cold. Wipe up
any gasoline that spills.
Do not fill the fuel tank completely full. Add
gasoline to the fuel tank until the level is 1/4" to
1/2" (6 mm to 13 mm) below the bottom of the
filler neck. This empty space in the tank allows
gasoline to expand.
Never smoke when handling gasoline, and stay
away from an open flame or where gasoline
fumes may be ignited by a spark.
Store gasoline in an approved container and
keep it out of the reach of children.
Never buy more than a 30-day supply of
gasoline.
1. Do not smoke near fuel.
2. Mix and pour fuel outdoors and where there are no
sparks or flames.
3. Always shut off the engine before refueling. Never
remove the String Trimmer fuel tank cap while the
engine is running or right after just stopping the
engine.
POTENTIAL HAZARD
Gasoline contains gasses that can build up
pressure inside a gas tank.
WHAT CAN HAPPEN
Fuel can be sprayed on you when removing gas
cap.
HOW TO AVOID THE HAZARD
Remove fuel cap slowly to avoid injury from
fuel spray.
