Fuel System - Briggs & Stratton 110000 Manual Del Operador

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 Check and Add Oil.
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, Figure 6). Remove oil from the dipstick with a clean cloth.
2. Slowly add oil into the engine oil fill (C, Figure 6). Do not overfill. Wait one minute
and then check the oil level.
3. Install and tighten the dipstick (A, Figure 6).
4. Remove the dipstick and check the oil level. The correct oil level is at the top of the
full indicator (B, Figure 6) on the dipstick.
5. Install and tighten the dipstick (A, Figure 6).
6. Connect the spark plug wire(s) to the spark plug(s). See Remove Oil section.
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 service requirements.
Different models will use a foam or a paper filter. Some models could also have an
optional pre-cleaner that can be washed and used again. Compare the illustrations in
this manual with the type installed on your engine and service as follows.
Foam Air Filter
1. Loosen or remove the fastener(s) (A, Figure 17), if installed.
2. Open or remove the cover (B, Figure 17).
3. Carefully remove the foam element (C, Figure 17) from the air filter base.
4. Clean the foam element (C, Figure 17) in liquid detergent and water. Compress the
foam element with your hands in a clean cloth until dry.
5. Soak the foam element (C, Figure 17) with clean engine oil. To remove unwanted
engine oil from the foam element, compress it with your hands in a clean cloth.
6. Install the foam element (C, Figure 17) onto the air filter base.
7. Close or install the cover (B, Figure 17) and attach with the fastener(s). Make sure
that the fastener(s) is tight.
Paper Air Filter
1. Loosen or remove the fastener(s), if installed, (A, Figure 18).
2. Open or remove the cover (B, Figure 18).
3. To prevent debris that falls into the carburetor, carefully remove the pre-cleaner (D,
Figure 18) and the filter (C) from the air filter base.
4. Remove the pre-cleaner (D, Figure 18), if installed, from the filter (C).
5. To loosen debris, lightly tap the filter (C, Figure 18) on a hard surface. If the filter is
very dirty, replace with a new filter.
6. Clean the pre-cleaner (D, Figure 18), if installed, in liquid detergent and water. Let
the pre-cleaner fully air dry. Do not add oil to the pre-cleaner.
7. Assemble the dry pre-cleaner (D, Figure 18), if installed, to the filter (C).
8. Install the filter (C, Figure 18) and the pre-cleaner (D) onto the air filter base. Make
sure that the filter fits tightly on the air filter base.
9. Close or install the cover (B, Figure 18) and secure with the fastener(s) (A). Make
sure that the fastener(s) is tight.
Servicing the Fuel System
WARNING
Fuel and its vapors are flammable and explosive. Fire or explosion could result in
burns or death.
• Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition
sources.
• Frequently examine the fuel lines, fuel tank, fuel cap, and connections for cracks
or leaks. Replace damaged parts.
• Before you clean or replace the fuel filter, drain the fuel tank or close the fuel
shut-off valve.
• If fuel spills, wait until it dries before you start the engine.
• 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.
Fuel Filter, if installed
1. Before you clean or replace the fuel filter (A, Figure 19), drain the fuel tank or close
the fuel shut-off valve. If the fuel tank is not drained, fuel leakage could occur and
cause a fire or explosion.
2. Use pliers to squeeze tabs (B, Figure 19) on the clamps (C), then move the clamps
away from the fuel filter (A). Twist and pull the fuel lines (D) off of the fuel filter.
3. Examine the fuel lines (D, Figure 19) for cracks or leaks. Replace if necessary.
4. Replace the fuel filter (A, Figure 19) with an original equipment replacement filter.
5. Attach the fuel lines (D, Figure 19) with clamps (C).
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

Fuel System

WARNING
Fuel and its vapors 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.
NOTE: Some models have a fuel tank for vertical storage that will let the engine tilt for
maintenance or storage (C, Figure 20). Do not keep in vertical position with the fuel tank
filled above the bottom of the fuel level indicator (D), if equipped. For more instructions,
refer to the equipment manual.
Keep the engine level (normal operating position). Fill the fuel tank (A, Figure 21) with
fuel. For fuel expansion, do fill above the fuel tank neck (B).
Fuel can become stale when kept in a storage container for more than 30 days. The
use of an alcohol-free fuel stabilizer and ethanol treatment in the fuel storage container
is recommended. This keeps fuel fresh and decreases fuel-related problems or
contamination in the fuel system.
When you fill the fuel container with fuel, add an alcohol-free fuel stabilizer as specified
by the manufacturer's instructions. If gasoline in the engine has not been treated with a
