Operation DANGER In certain conditions, fuel is extremely flammable and highly explosive. A fire or explosion from fuel can burn you and others and can damage property. • Fill the fuel tank outdoors, in an open area, when the engine is cold. Wipe up any fuel that spills. • Never fill the fuel tank inside an enclosed trailer. • Never smoke when handling fuel, and stay away from an open flame or where fuel fumes may be ignited by a spark.
3. Clean around each fuel tank cap and remove the cap. DANGER Important: Do not open the fuel tanks when parked on a hill. The fuel could spill out. Operating on icy or steep slopes can cause sliding and loss of control. 4. Add fuel to both fuel tanks, until the level is even with the bottom of the filler neck (Figure 40). Do not over fill the fuel tanks. A track dropping over an edge can cause a rollover, which may result in serious injury, death, or drowning. Always use the seat belt.
