Servicing the Exhaust System
WARNING
During operation, the engine and muffler become hot. If you touch a hot engine,
thermal burns can occur.
Combustible materials, such as leaves, grass and brush, can catch fire.
• Before you touch the engine or muffler, stop the engine and wait two (2)
minutes. Make sure that the engine and muffler are safe to touch.
• Remove debris from the muffler and engine.
It is a violation of California Public Resource Code, Section 4442, to use or operate the
engine on any forest-covered, brush-covered, or grass-covered land unless the exhaust
system is equipped with a spark arrester, as defined in section 4442, maintained in
effective working order. Other states or federal jurisdictions may have similar laws;
reference Federal Regulation 36 CFR Part 261.52. Contact the original equipment
manufacturer, retailer, or dealer to obtain a spark arrester designed for the exhaust
system installed on this engine.
Remove debris from the 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 the replacement parts
before you operate the equipment.
WARNING
Replacement parts must be of the same design and installed in the same position as the
original parts. Other parts could result in damage or an injury.
Change Engine Oil
WARNING
Fuel and its vapors are flammable and explosive. Fire or explosion could result in
burns or death.
During operation, the engine and muffler become hot. If you touch a hot engine,
thermal burns can occur.
• If you drain the oil from the top oil fill tube, the fuel tank must be empty. If it is not
empty, fuel leakage can occur and cause a fire or an explosion.
• Before you touch the engine or muffler, stop the engine and wait two (2)
minutes. Make sure that the engine and muffler are safe to touch.
Used oil is a hazardous waste product and must be discarded of correctly. Do not
discard with household waste. Contact your local authorities, service center, or dealer
for safe disposal or recycling facilities.
Remove Oil
1. With engine OFF but warm, disconnect the spark plug wire(s) (D, Figure 7), and
keep it away from the spark plug(s)(E).
2. Remove the dipstick (A, Figures 8, 9).
3. Remove the oil drain plug (F, Figures 10, 11). Drain the oil into an approved
container.
4. Install and tighten the oil drain plug (F, Figures 10, 11).
Change Oil Filter, if installed
1. Drain the oil from the engine. Refer to the Remove Oil section.
2. Remove the oil filter (G, Figures 12, 13) and discard correctly.
3. Before you install the new oil filter, lightly lubricate the oil filter gasket with clean oil.
4. Install the oil filter by hand until the gasket touches the oil filter adapter, then tighten
the oil filter 1/2 to 3/4 turns.
5. Add oil. Refer to the Add Oil section.
6. Start and operate the engine. When the engine is warm, do a check for oil leaks.
7. Stop the engine. Make sure that oil level is at the top of the full indicator on the
dipstick. Refer to the Add Oil section.
Add Oil
• Make sure the engine is level.
• Clean the oil fill area of all debris.
• Refer to the Specifications section for oil capacity.
1. Remove the dipstick (A, Figures 14, 15). Remove oil from the dipstick with a clean
cloth.
2. Slowly add oil into the engine oil fill (C, Figures 14, 15) Do not overfill. Wait one
minute and then check the oil level.
3. Install and tighten the dipstick (A, Figures 14, 15).

4. Remove the dipstick and check the oil level. The correct oil level is at the top of the
full indicator (B, Figures 14, 15) on the dipstick.
5. Install and tighten the dipstick (A, Figures 14, 15).
6. Connect the spark plug wire(s) (D, Figure 14) to the spark plug(s).
Servicing the Air Filter
WARNING
Fuel vapors are flammable and explosive. Fire or explosion could result in burns
or death.
• Do not start and operate 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 could result in
damage to the filter and solvents will dissolve the filter.
See the Maintenance Schedule for servicing requirements.
Some models have an optional pre-cleaner that can be cleaned and used again.
Compare the illustrations in this manual to the type installed on your engine.
1. Open the fastener(s) (A, Figure 16) and remove the cover (B).
2. Remove the nut (D, Figure 16) and retainer (E).
3. Remove the air filter (F, Figure 16).
4. Remove the pre-cleaner (G, Figure 16), if equipped, from the air filter (F).
5. To loosen debris, lightly tap the filter (F, Figure 16) on a hard surface. If the air filter
is dirty, replace it with a new filter.
6. Clean the pre-cleaner (G, Figure 16), if equipped, in liquid detergent and water. Let
the pre-cleaner fully air dry. DO NOT lubricate the pre-cleaner.
7. Assemble the dry pre-cleaner (G, Figure 16), if equipped, to the air filter (F).
8. Install the air filter (F, Figure 16) and attach with the retainer (E) and nut (D).
9. Install the cover (B, Figure 16).
Servicing the Cooling System
WARNING
During operation, the engine and muffler become hot. If you touch a hot engine,
thermal burns can occur.
Combustible debris, such as leaves, grass, and brush can catch fire.
• Before you touch the engine or muffler, stop the engine and wait two (2)
minutes. Make sure that the engine and muffler are safe to touch.
• Remove debris from the muffler and engine.
NOTICE
Do not use water to clean the engine. Water could cause contamination of the fuel
system. Use a brush or dry cloth to clean the engine.
This is an air cooled engine. Dirt or debris can prevent air flow and cause the engine to
become too hot and result in unsatisfactory performance and decreased 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 combustible
debris.
4. Make sure the oil cooler fins, if equipped, are clean.
After a period of time, the cylinder cooling fins can collect debris and cause the engine
to overheat. This unwanted material 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
Propane and natural gas are flammable and explosive. Fire or explosion could
result in burns or death.
Fuel Storage
• Because pilot lights or other ignition sources can cause explosions, keep fuel or
equipment away from furnaces, stoves, water heaters or other appliances that
have pilot lights.
Engine Oil
While the engine is warm, change the engine oil. Refer to Change the Engine Oil
section.
