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
reaches the FULL mark. Start the engine and check for
proper pressure before continuing to operate.
If the oil level is between the ADD and FULL marks, do
not start the engine. Contact an authorized dealer to
have the oil pressure problem corrected.
Fuel Recommendations
Fuel must meet these requirements:
•
Clean, fresh, unleaded gasoline.
•
A minimum of 87 octane/87 AKI (91 RON). High alti-
tude use, see below.
•
Gasoline with up to 10% ethanol (gasohol) or up to
15% MTBE (methyl tertiary butyl ether) is acceptable.
CAUTION: Do not use unapproved gasolines, such
as E85. Do not mix oil in gasoline or modify the engine
to run on alternate fuels. This will damage the engine
components and void the engine warranty.
To protect the fuel system from gum formation, mix a fuel
stabilizer into the fuel. See the Storage section. All fuel is
not the same. If starting or performance problems occur,
change fuel providers or change brands. This engine is
certified to operate on gasoline. The emissions control
system for this engine is EM (Engine Modifications).
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 adjustment information.
Operation of the engine at altitudes below 2,500 feet (762
meters) with the high altitude kit is not recommended.
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.
