Fuel Gauge
See Figure 1. Some models have a fuel gauge on the left side of the tank. The fuel gauge is not removable.
The fuel range feature may also be used to determine the remaining fuel. See Controls and Indicators → Instruments.
Fuel Filler Cap
WARNING
Avoid spills. Slowly open fuel filler cap. Do not fill above bottom of filler neck insert, leaving air space for fuel expansion. Secure filler cap after refueling. Gasoline is extremely flammable and highly explosive, which could result in death or serious injury. (00028b)
See Figure 1. To remove, turn fuel filler cap counterclockwise. The cap turns approximately three-quarters of a turn before it begins to loosen.
To install, turn fuel filler cap clockwise until it clicks. The ratchet action of the cap prevents overtightening.
See SAFE OPERATING RULES section and review safety procedures listed below.
