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
Fuel can become stale when stored over 30 days. Stale fuel causes acid and gum
deposits to form in the fuel system or onessential 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

to instructions.Run the enginefor 2 minutesto circulate thestabilizer throughout the fuel
system before storage.
If gasolinein the enginehas not beentreated witha fuel stabilizer, it must be drained into
an approved container. Run the engineuntil it stops fromlack of fuel. The use of a fuel
stabilizer in the storage container is recommended to maintain freshness.
