Storage
l_ 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
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.
For engines equipped with a FRESH START _ fuel cap, use Briggs & Stratton FRESH
START _ available in a drip concentrate cartridge.
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.
