We recommend the use of Briggs & Stratton
®
Warranty Certified oils for best
performance. Other high-quality detergent oils are permitted if classified for service SF,
SG, SH, SJ or higher. Do not use special additives.
Use the chart to select the best viscosity for the outdoor temperature range expected.
Engines on most outdoor power equipment operate well with 5W-30 Synthetic oil. For
equipment operated in hot temperatures, Vanguard
®
15W-50 Synthetic oil gives the best
protection.
A
SAE 30 -
Below 40 °F (4 °C) the use of SAE 30 will result in hard starting.
B
10W-30 -
Above 80 °F (27 °C) the use of 10W-30 may cause increased oil
consumption. Check the oil level frequently.
C
5W-30
D
Synthetic 5W-30

Check and Add Oil
Before you check or add oil
• Make sure the engine is level.
• Clean the oil fill area of debris.
• Refer to the
Specifications
section for oil capacity.
NOTICE
This engine was shipped from Briggs & Stratton without oil. Equipment manufacturers or
dealers could have added oil to the engine. Before you start the engine for the first time,
make sure that the oil is at the correct level. Add oil as specified by the instructions in
this manual. If you start the engine without oil, damage will occur and the engine will not
be repaired under warranty.
1. Remove the dipstick (A, Figure 3) and clean with a cloth.
2. Install and tighten the dipstick (A, Figure 3).
3. Remove the dipstick and check the oil level. Make sure that the oil level is at the
top of the full indicator (B, Figure 3) on the dipstick.
4. If the oil level is low, slowly add oil into the engine oil fill (C, Figure 3). Do not add
too much oil. After you add oil, wait one minute and check the oil level again. Make
sure that the oil level is correct.
5. Install and tighten the dipstick (A, Figure 3).
Low Oil Protection System (if equipped)
A low oil sensor is installed on some engines. If the oil is low, the sensor will display a
warning light or stop the engine. Stop the engine and follow these steps before you start
the engine.
• Make sure the engine is level.
• Do an oil check. Refer to the
Check Oil Level
section.
• If the oil level is low, add the correct amount of oil. Start the engine and make sure
the warning light (if equipped) does not come on.
• If the oil level is not low, do not start the engine. Contact a Briggs & Stratton
Authorized Service Dealer to have the oil problem corrected.
Fuel Recommendations
WARNING
Missing or inoperative automatic safety "fuel lock-off" valve can cause a fire or
explosion.
• DO NOT operate the equipment if the automatic safety "fuel lock-off" valve is missing
or inoperative.
Fuel must meet these requirements
• Use clean, dry fuel, free of moisture or any particulate material. Using fuels outside
the recommended values can cause performance problems.
• In engines set up to operate on LPG, commercial grade HD5 LPG is recommended.
Recommended fuel composition is fuel with a minimum fuel energy of 2500 BTU's/ft³
with maximum propylene content of 5% and butane and heavier gas content of 2.5%
and minimum propane content of 90%.
NG or LPG engines are certified to operate on natural or liquid propane gas. The
emissions control system for this engine is EM (Engine Modifications).
Add Fuel
WARNING
Fuel vapors are flammable and explosive. Fire or explosion could result in burns
or death.
When you add fuel
• Fill the fuel tank outdoors or in an area that has good airflow.
• Frequently examine the fuel lines, fuel tank, and connections for cracks or leaks.
Replace damaged parts.
For information on refueling natural or LP gas engines, read the operating instructions
supplied by the equipment manufacturer.
Start the Engine
WARNING
Fuel and its vapors are flammable and explosive. Fire or explosion could result in
burns or death.
When you start the engine
• Make sure that the spark plug, muffler, fuel cap and air cleaner (if equipped) are
correctly installed.
• Do not crank the engine with the spark plug removed.
• If the engine is flooded, set the choke (if equipped) to the OPEN or RUN position.
Move the throttle (if equipped) to the FAST position and crank until the engine starts.
• If there is natural or LP gas leakage in the area, do not start the engine.
• Because vapors are flammable, do not use pressurized starter fluids.
WARNING
POISONOUS GAS HAZARD. Engine exhaust contains carbon monoxide, a
poisonous gas that could kill you in minutes. Although you do not smell exhaust
fumes, you could still be exposed to dangerous carbon monoxide gas. If you feel
sick, dizzy, or weak while you use this product, get to fresh air RIGHT AWAY. See
a doctor. You may have carbon monoxide poisoning.
• Carbon monoxide gas can collect in occupied spaces. To reduce the risk of carbon
monoxide gas, ONLY operate this product outdoors and far away from windows,
doors and vents.
• Install battery-operated carbon monoxide alarms or plug-in carbon monoxide alarms
with battery back-up as specified by the manufacturer's instructions. Smoke alarms
cannot sense carbon monoxide gas.
• DO NOT operate this product in homes, garages, basements, crawlspaces, sheds, or
other closed spaces, even if you use fans or open doors and windows for ventilation.
After the operation of this product, carbon monoxide can quickly collect in these
spaces and stay for hours.
• ALWAYS put this product downwind and point the engine exhaust away from
occupied spaces.
