Fuel Filter, if equipped
1. Before cleaning or replacing the fuel filter (A, Figure 14), drain the fuel tank or
close the fuel shut-off valve. Otherwise, fuel can leak out and cause a fire or
explosion.
2. Use pliers to squeeze tabs (B, Figure 14) on the clamps (C), then slide the clamps
away from the fuel filter (A). Twist and pull the fuel lines (D) off of the fuel filter.
3. Check the fuel lines (D, Figure 14) for cracks or leaks. Replace if necessary.
4. Replace the fuel filter (A, Figure 14) with an original equipment replacement filter.
5. Secure the fuel lines (D, Figure 14) with clamps (C) as shown.
Fuel Strainer, if equipped
1. Remove the fuel cap (A, Figure 15).
2. Remove the fuel strainer (B, Figure 15).
3. If the fuel strainer is dirty, clean or replace it. If you replace the fuel strainer, make
sure to use an original equipment replacement fuel strainer.
Service Cooling System
WARNING
Running engines produce heat. Engine parts, especially muffler, become
extremely hot.
Severe thermal burns can occur on contact.
Combustible debris, such as leaves, grass, brush, etc., can catch fire.
• Allow muffler, engine cylinder and fins to cool before touching.
• Remove accumulated debris from muffler area and cylinder area.
NOTICE Do not use water to clean the engine. Water could contaminate the fuel
system. Use a brush or dry cloth to clean the engine.
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:16
Store the engine level (normal operating position). Fill fuel tank (A, Figure16) 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°
®
PROTECTION™to the fuel as
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.
