Engine Oil; Fuel System - Briggs & Stratton 80012812WST Manual Del Operario

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
ignition key.
Store battery in a cool, dry place and keep fully charged
during storage. 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® 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.

Engine Oil

While the engine is still warm, change the engine oil. See
Changing the Engine Oil section.
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.
