Fuel - Briggs & Stratton 110000 Series Operating & Maintenance Instructions

Fuel

Type of gasoline to use
This engine is certified to operate on gasoline. The
emission control system for this engine is EM (Engine
Modifications).
Always use gasoline that meets these requirements:
Clean, fresh unleaded gasoline.
•
A minimum of 87 octane/87 AKI (91 RON). If
•
operating at high altitude, see below.
Gasoline with up to 10% ethanol (gasohol) or up to
•
15% MTBE (methyl tertiary butyl ether), is
acceptable.
Use of any gasoline other than those approved
•
above will void the engine warranty. In some local
areas fuel pumps may be marked if the gasoline
contains alcohols or ethers. If you are unsure about
the gasoline you purchase check with your fuel
provider.
Do not modify the engine fuel system or carburetor
•
to run on alternative fuels.
Never mix oil with gasoline.
•
All gasoline is not the same. If you experience starting
or performance problems after new gasoline has been
used in your engine, switch to a different fuel provider or
change fuel brands.
CAUTION
Some fuels, called oxygenated or reformulated fuels,
are fuels blended with alcohols or ethers. Excessive
amounts of these blends can damage the fuel
system or cause performance problems. If any
undesirable operating symptoms occur, use
gasoline with a lower percentage of alcohol or ether.
Adding Fuel
1. Turn engine OFF and let engine cool at least 2
minutes before removing gas cap.
2. Remove cap. Fill tank to approximately 1 inch
(25mm) below top of neck to allow for fuel
expansion. Be careful not to overfill.
3. Replace cap before starting.
Fuel cap
Fuel Storage
Fuel can become stale when stored over 30 days. Stale
fuel causes acid and gum deposits to form in fuel
system or on essential carburetor parts. Mix fuel
stabilizer with fuel in tank or storage container. Run
engine for a short time to circulate stabilizer through
carburetor and engine. Engine and fuel can be stored
up to 24 months.
If fuel stabilizer is not used, you need to drain gasoline
from equipment prior to storage.
If the FRESH START continuous fuel preserver fuel cap
(concentrated liquid cartridge) is used, there is no need
to drain fuel, as long as cartridge contains stabilizer for
seasonal storage.
Fuel Stabilizer
To protect the fuel system from gum formation, use
Briggs & Stratton FRESH STARTt fuel stabilizer plus,
or FRESH START continuous fuel preserver fuel cap
(concentrated liquid cartridge), or FRESH START
preservative & stabilizer (granular).
High-altitude Use
At higher altitudes (over 5,000 feet), 85 octane/85 AKI
(89 RON) gasoline can be used. Operation at high
altitude may require a high-altitude carburetor jet kit to
improve performance and decrease fuel consumption.
See your local authorized Briggs & Stratton dealer for
more information.
Gasoline 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
•
2 minutes before removing gas cap.
Fill fuel tank outdoors or in well-ventilated
•
area.
Do not overfill fuel tank.
•
Keep gasoline 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.
