Oil Recommendations
We recommend the use of Briggs & Stratton Warranty Certified oils for best
performance. Other high-quality detergent oils areacceptable if classified for service SF,
SG, SH, SJ or higher. Do not use special additives.
Outdoor temperatures determine the proper oil viscosity for the engine. Use the chart to
select the best viscosity for the outdoor temperature range expected.
SAE 30
10W-30
Synthetic 5W-30
5W-30
°F °C
* 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 consumption. Check
oil level more frequently.
How To Check/Add Oil - Figure
2 4
Before adding or checking the oil
Place engine level.
Clean the oil fill area of any debris.
Models with oil fill cap (Figure 2)
1. Remove the oil fill cap (A).
2. To add oil, pour theoil slowly into the engine oil fill (B). Fill to point of overflowing.
3. Replace and tighten the oil fill cap.
Models with short dipstick (Figure 2)
1. Remove the dipstick (C) and wipe witha clean cloth.
2. Insert the dipstick but do not screw in. Oil level should be at FULL mark (D).
3. To add oil, pour theoil slowly into the engine oil fill (B). Fill to point of overflowing.
4. Replace and tighten the dipstick.
Models with extended dipstick (Figure 4)
1. Remove the dipstick (A) and wipe witha clean cloth.
2. Insert and tighten the dipstick.
3. Remove thedipstick andcheck the oillevel. Itshould be at the top of the fullindicator
(B) on the dipstick.
4. To add oil, pour theoil slowly into the engine oil fill (C). Do not overfill. After adding
oil, wait one minute and then recheck the oil level.
5. Replace and tighten the dipstick.
Low Oil Protection System (if equipped)
Some engines are equipped with a low oil sensor. If the oil is low, the sensor will either
activate awarning light orstop the engine.Stop the engineand followthese steps before
restarting the engine.
Make sure the engine is level.
Check the oil level. See the How To Check/Add Oil section.
If the oil level is low, add the proper amount of oil. Start the engine and makesure
the warning light (if equipped) is not activated.
If the oil level is not low, do not start the engine. Contact an Authorized Briggs &
Stratton Dealer to have the the oil problem corrected.
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.
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.
To protect the fuel system from gum formation, mix a fuel stabilizer intothe fuel. See
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 (EngineModifications).
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 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, no high altitude adjustment is necessary.

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 enginecool atleast 2minutes beforeremovingthe fuel
cap.
Fill fueltank outdoors orin 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.
Keepfuel awayfromsparks, openflames,pilot lights,heat,and otherignition
sources.
Check fuellines, tank, cap, andfittings frequently forcracks or leaks.
Replace ifnecessary
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 (B) with fuel. To allow for expansion of the fuel, do not fill above the
bottom of the fuel tank neck (C).
3. Reinstall the fuel cap.
How To Start The Engine - Figure
5 6 8
Rapid retraction of starter cord (kickback) will pull hand and arm
toward engine faster than you can let go.
Broken bones, fractures, bruises or sprains could result.
WARNING
When starting engine, pull the starter cord slowly until resistance is felt and then
pull rapidly to avoid kickback.
