Starting The Engine; Adding Fuel - Simplicity 2691127-0 Operator's Manual

High Altitude
At altitudes over 5,000 feet (1,524 meters), a minimum 85
octane/85 AKI (89 RON) gasoline is acceptable. To remain
emissions compliant, high altitude adjustment is required.
Operation without this adjustment will cause decreased
performance, increased fuel consumption, and increased
emissions. See an authorized dealer for high altitude ad-
justment information.
Operation of the engine at altitudes below 2,500 feet (762
meters) with the high altitude adjustment is not recom-
mended.

Adding Fuel

WARNING
Fuel and its vapors are extremely flammable and
explosive.
Fire or explosion can cause severe burns or
death.
When Adding Fuel
• Turn engine off and let engine cool at least 3 minutes
before removing the fuel cap.
• Fill fuel tank outdoors or in well-ventilated area.
• Do not overfill fuel tank. To allow for expansion of the
fuel, do not fill above the bottom of the fuel tank neck.
• Keep fuel away from sparks, open flames, pilot lights,
heat, and other ignition sources.
• Check fuel lines, tank, cap, and fittings frequently for
cracks or leaks. Replace if necessary.
• If fuel spills, wait until it evaporates before starting
engine.
1. Clean the fuel cap area of dirt and debris. Remove the
fuel cap (A, Figure 7). Also see Features and Controls
section.
2. Fill the fuel tank (B) with fuel. To allow for expansion of
the fuel, do not fill above the bottom of the fuel tank neck
(C).
3. Reinstall the fuel cap.
