may have similar laws. Contact the original equipment manufacturer, retailer, or
dealer to obtain a spark arrester designed for the exhaust system installed on this
engine.
Remove accumulated debris from muffler and cylinder area. Inspect the muffler for
cracks, corrosion, or other damage. Remove the deflector or the spark arrester, if
equipped, and inspect for damage or carbon blockage. If damage is found, install
replacement parts before operating.
WARNING
Replacement parts must be of the same design and installed in the same position
as the original parts. Other parts may not perform as well, may damage the unit, and
may result in injury.
Change Engine Oil
See Figure: 14, 15, 16
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
Running engines produce heat. Engine parts, especially muffler, become
extremely hot.
Severe thermal burns can occur on contact.
• When you drain the oil from the top oil fill tube, the fuel tank must be empty or fuel
can leak out and result in a fire or explosion.
• Allow muffler, engine cylinder and fins to cool before touching.
Used oil is a hazardous waste product and must be disposed of properly. Do not discard
with household waste. Check with your local authorities, service center, or dealer for
safe disposal/recycling facilities.
For

models, an oil change is not required. If you desire to change
oil, then follow the procedure below.
Remove Oil
The oil must be drained from the top oil fill tube.
1.
With engine off but still warm, disconnect the spark plug wire (D, Figure 14) and
keep it away from the spark plug (E).
2.
Remove the dipstick (A, Figure 15).
3.
When you drain the oil from the top oil fill tube (C, Figure 16), keep the spark plug
(E) end of the engine up. Drain the oil into an approved container.
WARNING
When you drain the oil from the top oil fill tube, the fuel tank must be empty or fuel
can leak out and result in a fire or explosion. To empty the fuel tank, run the engine
until it stops from lack of fuel.
Add Oil
• Make sure the engine is level.
• Clean the oil fill area of any debris.
• See the
Specifications
section for oil capacity.
1.
Remove the dipstick (A, Figure 15) and wipe with a clean cloth.
2.
Slowly pour oil into the engine oil fill (C, Figure 15).
Do not overfill.
After adding
oil, wait one minute and then check the oil level.
3.
Install and tighten the dipstick (A, Figure 15).
4.
Remove the dipstick and check the oil level. Correct oil level is at the top of the full
indicator (B, Figure 15) on the dipstick.
5.
Reinstall and tighten the dipstick (A, Figure 15).
6.
Connect the spark plug wire (D, Figure 14) to the spark plug (E).
Service Air Filter
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.
Various models use either a foam or a paper filter. Some models may also have an
optional pre-cleaner that can be washed and reused. Compare the illustrations in this
manual with the type installed on your engine and service as follows.
Foam Air Filter
See Figure: 17
1.
Open the cover (B, Figure 17).
2.
Remove the foam element (C, Figure 17).
3.
Wash the foam element (C, Figure 17) in liquid detergent and water. Squeeze dry
the foam element in a clean cloth.
4.
Saturate the foam element (C, Figure 17) with clean engine oil. To remove the
excess engine oil, squeeze the foam element in a clean cloth.
5.
Install the foam element (C, Figure 17).
6.
Close the cover (B, Figure 17).
Paper Air Filter
See Figure: 18
1.
Open the cover (B, Figure 18).
2.
Remove the filter (C, Figure 18).
3.
Remove the pre-cleaner (E, Figure 18), if equipped, from the filter. To loosen
debris, gently tap the filter on a hard surface. If the filter is excessively dirty,
replace with a new filter.
4.
Wash the pre-cleaner in liquid detergent and water. Then allow it to thoroughly air
dry.
Do not
oil the pre-cleaner.
5.
Assemble the dry pre-cleaner, if equipped, to the filter.
6.
Install the filter (C, Figure 18).
7.
Close the cover (B, Figure 18).
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.
