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.
Fuel System
See Figure: 13
Store the engine level (normal operating position). Fill fuel tank (A, Figure 13) with fuel.
To allow for expansion of fuel, do not overfill above the fuel tank neck (B).
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.
