Start The Engine - Snapper 2691556, 2691663 Manual Del Operador

• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane/87 AKI (91 RON). High altitude
use, see below.
• Gasoline with up to 10% ethanol (gasohol) is acceptable.
NOTICE Do not use unapproved gasolines, such as E15
and E85. Do not mix oil in gasoline or modify the engine to
run on alternate fuels. Use of unapproved fuels will damage
the engine components, which will not be covered under
warranty.
To protect the fuel system from gum formation, mix a fuel
stabilizer into the fuel. See Storage. All fuel is not the same.
If start or performance problems occur, change fuel providers
or brands. This engine is certified to operate on gasoline.
The emissions control system for carbureted engines is EM
(Engine Modifications). The emissions control systems for
engines with electronic fuel injection are ECM (Engine Control
Module), MPI (Multi Port Injection), and if equipped an O2S
(Oxygen Sensor).
High Altitude
At altitudes over 5,000 feet (1524 meters), a minimum 85
octane/85 AKI (89 RON) gasoline is acceptable.
For carbureted engines, high altitude adjustment is
required to maintain performance. Operation without this
adjustment will cause decreased performance, increased
fuel consumption, and increased emissions. Contact
a Briggs & Stratton Authorized Service Dealer for high
altitude adjustment information. Operation of the engine at
altitudes below 2,500 feet (762 meters) with the high altitude
adjustment is not recommended.
For Electronic Fuel Injection (EFI) engines, no high altitude
adjustment is necessary.
Add Fuel
WARNING
Fuel and its vapors are extremely flammable and explosive.
Always handle fuel with extreme care. Failure to Observe
these safety instructions can cause fire or explosion which
could result in severe burns or death.
When Adding Fuel

minutes before you remove the fuel cap.
• Extinguish all cigarettes, cigars, pipes, and other

• 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 you start the
engine and avoid creating any source of ignition.
• Use only an approved fuel container.
1. Remove unwanted material from the fuel cap area.
2. Remove the fuel cap (A, Figure 7).

Engines give off carbon monoxide, an odorless, colorless,
poison gas.
Breathing carbon monoxide can cause nausea, fainting, or
death.
Fire or explosion can cause severe burns or death.
• Start and operate the engine outdoors.
• Do not start or operate the engine in enclosed area,
even if doors or windows are open.
