Fire or explosion can cause severe burns or death.
Fuel leakage and fire hazard.
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.
Do not store in vertical position with fuel tank filled above the bottom of the fuel

tank neck.
Mow N' Stowt
Fold down the handle and tip up for storage as shown in Figure 14. See the equipment
manual for details.
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 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.
NOTICE: If the engine is tipped for storage, the fuel tank must not be filled above the
bottom of the fuel tank neck and the spark plug side must be up. 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.
