Remove Oil
1. With engine off but still warm, disconnect the spark plug wire (D, Figure 9) and keep
it away from the spark plug (E).
2. Remove the oil drain plug (F, Figure 10). Drain the oil into an approved container.
Note:
Any of the oil drain plugs (G, Figure 10) may be installed in the engine.
3. After the oil has drained, install and tighten the oil drain plug (F, Figure 10).
Add Oil
• Make sure the engine is level.
• Clean the oil fill area of any debris.
• See the
Specifications
section for oil capacity.
Short Dipstick, if equipped
1. Remove the dipstick (A, Figure 10) and wipe with a clean cloth.
2. Slowly pour oil into the engine oil fill (C, Figure 10). Fill to point of overflowing.
3. Install the dipstick (A, Figure 10). Do not turn or tighten. Remove and check the
oil level. Correct oil level is at the top of the full indicator (B) on the dipstick.
4. Reinstall and tighten the dipstick (A, Figure 10).
5. Connect the spark plug wire (D, Figure 9) to the spark plug (E).
Extended Dipstick, if equipped
1. Remove the dipstick (A, Figure 11) and wipe with a clean cloth.
2. Slowly pour oil into the engine oil fill (C, Figure 11). Do not overfill. After adding oil,
wait one (1) minute and then recheck the oil level.
3. Install and tighten the dipstick (A, Figure 11).
4. Remove and check the oil level. Correct oil level is at the top of the full indicator (B,
Figure 11) on the dipstick.
5. Reinstall and tighten the dipstick (A, Figure 11).
6. Connect the spark plug wire (D, Figure 9) to the spark plug (E).
Air Filter
The engine is not equipped with an air filter. DO NOT use this engine for anything other
than snow removal.
Storage
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
When Storing Fuel Or Equipment With Fuel In Tank
• Store away from furnaces, stoves, water heaters or other appliances that have pilot
lights or other ignition sources because they can ignite fuel vapors.
NOTICE
Store the engine level (normal operating position). If the engine is tipped for
maintenance, the fuel tank must be empty and the spark plug side must be up. If the
fuel tank is not empty and if the engine is tipped in any other direction, it may be difficult
to start due to oil or gasoline contaminating the air filter and/or the spark plug.
Fuel System
Fuel can become stale when stored over 30 days. Stale fuel causes acid and gum deposits
to form in the fuel system or on essential carburetor parts. To keep fuel fresh, use Briggs
& Stratton Advanced Formula Fuel Treatment & Stabilizer, available wherever Briggs
& Stratton genuine service parts are sold.
There is no need to drain gasoline from the engine if a fuel stabilizer is added according
to instructions. Run the engine for two (2) minutes to circulate the stabilizer throughout the
fuel system before storage.
If gasoline in the engine has not been treated with a fuel stabilizer, it must be drained into
an approved container. Run the engine until it stops from lack of fuel. The use of a fuel
stabilizer in the storage container is recommended to maintain freshness.
Engine Oil
While the engine is still warm, change the engine oil. See the
Change Engine Oil
section.

Engine power will decrease 3.5% for each 1,000 feet (300 meters) above sea level and
1% for each 10° F (5.6° C) above 77° F (25° C). The engine will operate satisfactorily at
an angle up to 15°. Refer to the equipment operator's manual for safe allowable operating
limits on slopes.

We recommend that you see any Briggs & Stratton Authorized Dealer for all maintenance
and service of the engine and engine parts.
Power Ratings: The gross power rating for individual gasoline engine models is labeled
in accordance with SAE (Society of Automotive Engineers) code J1940 Small Engine
Power & Torque Rating Procedure, and is rated in accordance with SAE J1995. Torque
values are derived at 2600 RPM for those engines with “rpm” called out on the label and
3060 RPM for all others; horsepower values are derived at 3600 RPM. The gross power
curves can be viewed at www.BRIGGSandSTRATTON.COM. Net power values are taken
with exhaust and air cleaner installed whereas gross power values are collected without
these attachments. Actual gross engine power will be higher than net engine power and
is affected by, among other things, ambient operating conditions and engine-to-engine
variability. Given the wide array of products on which engines are placed, the gasoline
engine may not develop the rated gross power when used in a given piece of power
equipment. This difference is due to a variety of factors including, but not limited to, the
variety of engine components (air cleaner, exhaust, charging, cooling, carburetor, fuel
pump, etc.), application limitations, ambient operating conditions (temperature, humidity,
altitude), and engine-to-engine variability. Due to manufacturing and capacity limitations,
Briggs & Stratton may substitute an engine of higher rated power for this engine.
