3.
Install and tighten the oil drain plug (B, Figure 23).
4.
To fill, slowly pour oil (see Specifications section) into the oil fill (C, Figure 23).
5.
Install the dipstick (A, Figure 23).
6.
Remove the dipstick (A, Figure 23) and check the oil level. Correct oil level is at
the top of the oil fill indicator (D) on the dipstick.
7.
Install the dipstick (A, Figure 23).
Service Air Filter
See Figure: 24
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
• Never start and run the engine with the air cleaner assembly (if equipped) or the
air filter (if equipped) removed.
NOTICE
Do not use pressurized air or solvents to clean the filter. Pressurized air
can damage the filter and solvents will dissolve the filter.
See the Maintenance Schedule for service requirements.
Paper Air Filter
1.
Loosen the fastener(s) (C, Figure 24).
2.
Remove the cover (A, Figure 24).
3.
Remove the filter (B, Figure 24).
4.
To loosen debris, gently tap the filter (B, Figure 24) on a hard surface. If the filter is
excessively dirty, replace with a new filter.
5.
Install the filter (B, Figure 24) .
6.
Install the cover (A, Figure 24) and secure with the fastener(s) (C). Make sure the
fastener(s) is tight.
Service Fuel System
See Figure: 25
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
• Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition
sources.
• Check fuel lines, tank, cap, and fittings frequently for cracks or leaks. Replace if
necessary.
• Before cleaning or replacing the fuel filter, drain the fuel tank or close the fuel shut-
off valve.
• If fuel spills, wait until it evaporates before starting engine.
• Replacement parts must be the same and installed in the same position as the
original parts.
Fuel Strainer, if equipped
1.
Remove the fuel cap (A, Figure 25).
2.
Remove the fuel strainer (B, Figure 25).
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.
12
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: 26
Store the engine level (normal operating position). Fill fuel tank (A, Figure 26) 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.
