Oil Pressure - Briggs & Stratton 2691670 Manual Del Operador

6

Oil Pressure

If the oil pressure is too low, a pressure switch (if equipped)
will either stop the engine or activate a warning device on the
equipment. If this occurs, stop the engine and check the oil
level with the dipstick.
If the oil level is below the ADD mark, add oil until it touches
the FULL mark. Start the engine and check for the correct oil
pressure before you continue to operate the machine.
If the oil level is between the ADD and FULL marks, DO NOT
start the engine. Contact an authorized service dealer to
correct the oil pressure problem.
Add Fuel
Fuel must meet these requirements:
10
• Clean, unleaded gasoline.
• A minimum of 87 octane / 87 AKI (91 RON). See High
Altitude Requirements.
• Gasoline with up to 10% ethanol (gasohol).
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 cause
damage to engine components, which will not be covered
under warranty.
• This engine is certified to operate on gasoline.
• The emissions control system for carbureted engines is
EM (Engine Modifications).
• The emissions control system for engines with electronic
fuel injection are ECM (engine control module), MPI (multi
port injection) and if equipped an 02S (oxygen sensor).
High Altitude Requirements
• At altitudes over 5,000 feet (1,524 meters), a minimum 85
octane / 85 AKI (89 RON) gasoline is acceptable.
• For carbureted engines, high altitude adjustment is
required to remain emissions compliant. 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, high altitude
adjustment is not necessary.
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
• Stop the engine and let the engine cool at least 3
minutes before you remove the fuel cap.
• Extinguish all cigarettes, cigars, pipes, and other
sources of ignition.
• 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 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).
