Service Air Filter - Briggs & Stratton Vanguard 611400 Manual Del Operario

Change Oil Filter, if equipped
Some models are equipped with an oil filter. For replacement intervals, see the
Maintenance Schedule.
1. Drain the oil from the engine. See Remove Oil section.
2. Remove the oil filter (G, Figure 9) and dispose of properly.
3. Before you install the new oil filter, lightly lubricate the oil filter gasket with fresh,
clean oil.
4. Install the oil filter by hand until the gasket contacts the oil filter adapter, then tighten
the oil filter 1/2 to 3/4 turns.
5. Add oil. See Add Oil section.
6. Start and run the engine. As the engine warms up, check for oil leaks.
7. Stop the engine and check the oil level. Correct oil level is at the top of the full indicator
(B, Figure 8) on the dipstick.
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 8) and wipe with a clean cloth.
2. Slowly pour oil into the engine oil fill (C, Figure 8). Do not overfill. After adding oil,
wait one minute and then check the oil level.
3. Install and tighten the dipstick (A, Figure 8).
4. Remove the dipstick and check the oil level. Correct oil level is at the top of the full
indicator (B, Figure 8) on the dipstick.
5. Reinstall and tighten the dipstick (A, Figure 8).
6. Connect the spark plug wire(s) (D, Figure 7) to the spark plug(s) (E).

Service Air Filter

See Figure: 10
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.
The air filter system uses a paper filter with an optional pre-cleaner. The pre-cleaner can
be washed and reused.
1. Remove the fastener(s) (A, Figure 10).
2. Remove the cover (B, Figure 10).
3. Remove the fastener(s) (C, Figure 10) and retainer (D).
4. Remove the air filter (E, Figure 10).
5. Remove the pre-cleaner (F, Figure 10), if equipped, from the air filter (E).
6. To loosen debris, gently tap the air filter (E, Figure 10) on a hard surface. If the air
filter is excessively dirty, replace with a new air filter.
7. Wash the pre-cleaner (F, Figure 10), if equipped, in liquid detergent and water. Allow
the pre-cleaner to thoroughly air dry. Do not oil the pre-cleaner.
8. Assemble the dry pre-cleaner (F, Figure 10), if equipped, to the air filter (E).
9. Install the air filter (E, Figure 10) and secure with retainer (D) and fastener(s) (C).
10. Install the cover (B, Figure 10) and secure with the fastener(s) (A). Make sure the
fastener(s) is tight.
Service Fuel System
See Figure: 11
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 Filter, if equipped
1. Before replacing the fuel filter (A, Figure 11), if equipped, 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 11) 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 11) for cracks or leaks. Replace if necessary.
4. Replace the fuel filter (A, Figure 11) with an original equipment replacement filter.
5. Secure the fuel lines (D, Figure 11) with clamps (C) as shown.
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: 12
Store the engine level (normal operating position). Fill fuel tank (A, Figure 12) with fuel.
To allow for expansion of fuel, do not overfill above the fuel tank neck (B).
