Outdoor temperatures determine the proper oil viscosity for
the engine. Use the chart to select the best viscosity for the
outdoor temperature range expected.
* Below 40°F (4°C) the use of SAE 30 will result in hard starting.
** Above 80°F (27°C) the use of 10W-30 may cause increased oil con-
sumption. Check oil level more frequently.
How To Check/Add Oil
Before adding or checking the oil
• Place engine level.
• Clean the oil fill area of any debris.
1. Remove the dipstick (A, Figure 2) and wipe with a
clean cloth.
2. Insert and tighten the dipstick.
3. Remove the dipstick and check the oil level. It should
be at the top of the full indicator (B, Figure 2) on the
dipstick.
4. If low, add oil slowly into the engine oil fill (C, Figure
2). Do not overfill. After adding oil, wait one minute
and then recheck the oil level.
5. Replace and tighten the dipstick.
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) is accept-
able.
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. This will damage the engine compo-
nents and void the engine warranty.
To protect the fuel system from gum formation, mix a fuel
stabilizer into the fuel. Refer to "Storage". 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)
16
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 a Briggs & Stratton 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.
How To Add Fuel
WARNING
!
Fuel and its vapors are extremely flammable and explo-
sive.
Fire or explosion can cause severe burns or death.
When Adding Fuel
• Turn engine off and let engine cool at least 5 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.
1. Clean the fuel cap area of dirt and debris. Remove the
fuel cap (A, Figure 3).
2. Fill the fuel tank with fuel. To allow for expansion of the
fuel, do not fill above the bottom of the fuel tank neck
(B, Figure 3).
3. Reinstall the fuel cap. Make sure the vent (C, Figure
3) is open after refueling.
Operator Seat Adjustment
1. With the engine stopped, loosen the two adjusting
knobs (A, Figure 4) and move the seat to the desired
position. After adjustment, tighten the knobs securely.
NOTE: If the seat does not move after loosening the knobs,
it may be necessary to loosen the 5/16" patch lock screws
or hex nuts (B, Figure 4) located at the rear of the seat.
