Storage

WARNING
Never store the unit (with fuel) in an enclosed,
unventilated structure. Fuel vapors can travel
to an ignition source (such as a furnace, water
heater, etc.) and cause an explosion. Fuel vapor
is also toxic to humans and animals.
When Storing Fuel Or Equipment With Fuel in Tank
• S tore away from furnaces, stoves, water heaters, or
other appliances that have pilot lights or other ignition
sources because they can ignite fuel vapors.

Equipment

Disengage the PTO, set the parking brake, and remove the
starter insert.
Store battery in a cool, dry place and fully charge about
once a month. If the battery is left in the unit, disconnect the
negative cable.

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 FRESH START® fuel stabilizer, available as a
liquid additive or 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. The engine and fuel can then be stored up to 24
months.
If gasoline in the tank 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.

Before starting the unit after it has been stored:
• Check all fluid levels. Check all maintenance items.
• Perform all recommended checks and procedures found
in the engine owner's manual.
• Allow the engine to warm up for several minutes before
use.
