Troubleshooting; Specifications - Briggs & Stratton 080000 Operator's Manual

3. When you drain the oil from the top oil fill tube (C, Figure 15), 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. If it is not
empty, fuel leakage can occur and could result in a fire or an explosion. Operate the
engine until the fuel tank is empty.
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 14). Remove oil from the dipstick with a clean cloth.
2. Slowly add oil into the engine oil fill (C, Figure 15). Do not overfill. Wait one
minute and then check the oil level.
3. Install and tighten the dipstick (A, Figure 14).
4. Remove the dipstick and check the oil level. The correct oil level is at the top of the
full indicator (B, Figure 14) on the dipstick.
5. Install and tighten the dipstick (A, Figure 14).
6. Connect the spark plug wire(s) (D, Figure13) to the spark plug(s) (E).
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 16), if equipped, that secure the cover.
2. Open or remove the cover (B, Figure 16).
3. Carefully remove the foam element (C, Figure 16) from the air filter base.
4. Clean the foam element (C, Figure 16) 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 16) with clean engine oil. To remove the excess
engine oil, compress the foam element with your hands in a clean cloth.
6. Install the foam element (C, Figure 16) onto the air filter base.
7. Close or install the cover (B, Figure 16) and attach with the fastener(s). Make sure
the fastener(s) is tight.
Paper Air Filter
1. Remove the cover (B, Figure 17).
2. Remove the filter (C, Figure 17).
3. Remove the pre-cleaner (E, Figure 17), if equipped, from the filter (C). Lightly tap
the filter on a hard surface to remove unwanted material. If the filter is dirty replace
it a new filter.
4. Clean the pre-cleaner (E, Figure 17), if equipped, in liquid detergent and water. Let
the pre-cleaner fully air dry. Do not add oil to the pre-cleaner.
5. Assemble the dry pre-cleaner (E, Figure 17), if equipped, to the filter (C).
6. Install the filter (C, Figure 17).
7. Install the cover (B, Figure 17).
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 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
Fuel System
NOTE: Some models have a fuel tank for vertical storage that will let the engine tilt for
maintenance or storage (C, Figure 18). 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 19) with
fuel. For fuel expansion, do fill above the fuel tank neck (B).
If gasoline in the engine has not been treated with a fuel stabilizer, it must be drained
into an approved container. Operate the engine until it stops from lack of fuel. The use of
a fuel stabilizer in the storage container is recommended to keep fuel fresh.
Engine Oil
While the engine is still warm, change the engine oil. Refer to Change the Engine Oil
section.
