Fuel System; Engine Oil - Briggs & Stratton 2691351-00 Operator's Manual

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
• Store 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
key.
Battery life will be increased if it is removed. Put in a cool,
dry place and keep fully charged during storage. If the bat-
tery 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
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.
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 this manual.
• Allow the engine to warm up for several minutes before
use.
