Fuel System; Engine Oil - Briggs & Stratton 120000 Manual Del Operario

This is an air cooled engine. Dirt or debris can restrict air flow and cause the engine to
overheat, resulting in poor performance and reduced engine life.
1. Use a brush or dry cloth to remove debris from the air intake grille.
2. Keep linkage, springs and controls clean.
3. Keep the area around and behind the muffler, if equipped, free of any combustible
debris.
4. Make sure the oil cooler fins, if equipped, are free of dirt and debris.
After a period of time, debris can accumulate in the cylinder cooling fins and cause the
engine to overheat. This debris cannot be removed without partial disassembly of the
engine. Have a Briggs & Stratton Authorized Service Dealer inspect and clean the air
cooling system as recommended in the Maintenance Schedule.
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

See Figure: 20
Store the engine level (normal operating position). Fill fuel tank (A, Figure 20) with fuel.
To allow for expansion of fuel, do not overfill above the fuel tank neck (B).
Fuel can become stale when kept in a storage container for more than 30 days. Each
time you fill the container with fuel, add STA-BIL 360°
specified by the manufacturer's instructions. This keeps fuel fresh and decreases fuel-
related problems or contamination in the fuel system.
It is not necessary to drain fuel from the engine when STA-BIL
®
360° PROTECTION™ is added as instructed. Before storage, turn the engine ON for 2
minutes to move the fuel and stabilizer through the fuel system.
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. See the Change Engine Oil
section.

Engine power will decrease 3.5% for each 1,000 feet (300 meters) above sea level and
1% for each 10° F (5.6° C) above 77° F (25° C). The engine will operate satisfactorily
at an angle up to 15°. Refer to the equipment operator's manual for safe allowable
operating limits on slopes.
