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.
Check and Add Engine Oil
1. Place the tractor on a level surface (see Figure 4).
CAUTION: 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 and void the engine 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 starting or performance problems occur, change
fuel providers or change brands. This engine is certied to
operate on gasoline. The emissions control system for this
engine is EM (Engine Modications).
High Altitude
At altitudes over 5,000 feet (1524 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 Briggs & Stratton Dealer for
high altitude adjustment information.
Operation of the engine at altitudes below 2,500 feet (762
meters) with high altitude adjustment is not recommended.
Fuel Recommendations
Fuel must meet these requirements:
• 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.
2. Stop the engine.
3. Clean the oil ll area of any debris and remove.
4. Remove the dipstick and wipe with a clean cloth (see
Figure 5).
5. Fully insert the dipstick.
6. Remove the dipstick and check the oil level. It should be
at the FULL mark on the dipstick.
7. If FULL, insert the dipstick and tighten securely.
If LOW, add oil slowly into the engine oil ll tube (see Oil
Recommendations).  After adding oil,
wait one minute, then check the oil level.
