Service Air Filter - Briggs & Stratton 300 Serie Manuel De L'opérateur

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.
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 8) and keep
it away from the spark plug (E).
2. Remove the dipstick (A, Figure 9).
3. When you drain the oil from the top oil fill tube (C, Figure 10), 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 9) and wipe with a clean cloth.
2. Slowly pour oil into the engine oil fill (C, Figure 9). Do not overfill. After adding oil,
wait one minute and then check the oil level.
3. Install and tighten the dipstick (A, Figure 9).
4. Remove the dipstick and check the oil level. Correct oil level is at the top of the full
indicator (B, Figure 9) on the dipstick.
5. Reinstall and tighten the dipstick (A, Figure 9).
6. Connect the spark plug wire (D, Figure 8) to the spark plug (E).

Service Air Filter

See Figure: 11, 12
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
1. Open the cover (B, Figure 11).
2. Remove the foam element (C, Figure 11).
3. Wash the foam element (C, Figure 11) in liquid detergent and water. Squeeze dry
the foam element in a clean cloth.
4. Saturate the foam element (C, Figure 11) 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 11).
6. Close the cover (B, Figure 11).
Paper Air Filter
1. Open the cover (B, Figure 12).
2. Remove the filter (C, Figure 12).
3. To loosen debris, gently tap the filter (C, Figure 12) on a hard surface. If the filter is
excessively dirty, replace with a new filter.
4. Install the filter (C, Figure 12).
5. Close the cover (B, Figure 12).
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.
NOTICE Store the engine level (normal operating position). If the engine is tipped for
maintenance, the fuel tank must be empty and the spark plug side must be up. If the
fuel tank is not empty and if the engine is tipped in any other direction, it may be difficult
to start due to oil or gasoline contaminating the air filter and/or the spark plug.
Fuel System
Fuel can become stale when stored over 30 days. Stale fuel causes acid and gum deposits
to form in the fuel system or on essential carburetor parts. To keep fuel fresh, use Briggs
& Stratton Advanced Formula Fuel Treatment & Stabilizer, available wherever Briggs
& Stratton genuine service parts are sold.
There is no need to drain gasoline from the engine if a fuel stabilizer is added according
to instructions. Run the engine for two (2) minutes to circulate the stabilizer throughout the
fuel system before storage.
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.
