Oil Recommendations
We recommend the use of Briggs & Stratton Warranty Certified oils for best
performance. Other high-quality detergent oils are acceptable 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

Before adding or checking the oil
• Place engine level.
• Clean the oil fill area of any debris.
1. Remove the oil fill cap (A, Figure 2).
2. To add oil, pour the oil slowly into the engine oil fill ( B). Fill to point of overflowing.
3. Replace and tighten the oil fill cap.
Fuel Recommendations
Fuel must meet these requirements:
• Clean, fresh, unleaded gasoline.
• A minimum of 87 octane/87 AKI (91RON). High altitude 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 willdamage 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 thesame. 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 (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.

WARNING
Gasoline and its vapors are extremely flammable and explosive.
Fire or explosioncan cause severe burns or death.
When Adding Fuel
• Turn engine off and let engine coolat least2 minutesbefore removingthe fuelcap.
• Fill fuel tank outdoors or in well-ventilated area.
• Do not overfill fuel tank. Fill tank to approximately 1.5 inches (38 mm) below top of
neck to allow for fuel expansion.
• Keepgasoline awayfrom sparks,open flames,pilot lights,heat, andotherignition
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 (B) with gasoline. To allowfor expansion of the gasoline, do not fill
above the bottom of the fuel tank neck (C).
3. Reinstall the fuel cap.
How To Start The Engine - Figure

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 slo wly until resistance is felt and then pull
rapidly to avoid kickback.
WARNING
Gasoline and its vapors are extremely flammable and explosive.
Fire or explosioncan cause severe burns or death.
When Starting Engine
• Ensure that spark plug, muffler, fuel cap and air cleaner are in place and secured.
• Do not crank engine with spark plug removed.
• If engine floods, set choke (if equipped) to open/run position, move throttle (if
equipped) to fast position and crank until engine starts.
Engines give off carbon monoxide, an odorless, colorless, poison gas.
Breathing carbon monoxide can cause nausea, fainting or death.
WARNING
• Start and runengine outdoors.
• Do not start or run engine in enclosed area, even if doors or windows are open.
CAUTION: This engine was shipped from Briggs & Stratton without oil. Before you start
the engine, makesure you add oil according to t he instructions in this manual. If you
start the engine without oil, it will be damaged beyond repair and will not be covered
under warranty.
1. Check the oil level. See the How To Check/Add Oil section.
2. Make sure equipmentdrive controls, if equipped,are disengaged. Seetheequipment
manual for location and operation of these controls.
3. Move the choke control lever (A) to the choke
position (Figure 4).
Note: Choke is usually unnecessary when restarting a warm engine.
4. Move the throttle control lever ( B), if equipped, to the fast
position. Operate
the engine with the throttle control lever in the fast position.
5. On engines equipped with a stop switch (C), move the switch to the on position.
6. Firmly hold the starter cord handle (D). Pull thestarter cord handle slowly until
resistance is felt, then pull rapidly.
