Briggs & Stratton 100000 Guide De L'utilisateur page 8

NOTICE
The equipment manufacturer specifies the maximum speed for the engine as installed
on the equipment. Do not exceed this speed. If you are not sure what the equipment
maximum speed is, or what the engine speed is set to from the factory, contact a Briggs
& Stratton Authorized Service Dealer for assistance. For safe and correct operation
of the equipment, the engine speed should only be adjusted by a qualified service
technician.
Servicing the Spark Plug
Check the spark plug gap (A, Figure 9) with a wire gauge (B). If necessary, set the
spark plug gap. Install and tighten the spark plug to the correct torque. For gap and
torque specifications, refer to the Specifications section.
NOTE: In some areas, it is mandatory by local law that you use a resistor spark plug
to decrease ignition signals. If a resistor spark plug was installed by the equipment
manufacturer, use the same type for replacement.
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 the engine OFF but warm, disconnect the spark plug wire (D, Figure 10), and
keep it away from the spark plug (E).
2. Remove the oil drain plug (F, Figure 11). Drain the oil into an approved container.
NOTE: All of the oil drain plugs (G, Figure 11) can be installed in the engine.
3. Install and tighten the oil drain plug (F, Figure 11).
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 12). Remove oil from the dipstick with a clean cloth.
2. Slowly add oil into the engine oil fill (C, Figure 12) Do not overfill. Wait one minute
and then check the oil level.

3. Install and tighten the dipstick (A, Figure 12).
4. Remove the dipstick and check the oil level. The correct oil level is at the top of the
full indicator (B, Figure 12) on the dipstick.
5. Install and tighten the dipstick (A, Figure 12).
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.
Paper Air Filter
1. Loosen the fastener(s) (C, Figure 13).
2. Remove the cover (A, Figure 13) and the filter (B).
3. To loosen debris, lightly tap the filter (B, Figure 13) on a hard surface. If the filter is
dirty, replace it with a new filter.
4. Install the filter (B, Figure 13).
5. Install the cover (A, Figure 13) with the fastener(s) (C). Make sure that the
fastener(s) is tight.
Paper Air Filter
1. Loosen the fastener(s) (A, Figure 14).
2. Remove the cover (B, Figure 14).
3. Remove the fastener (E, Figure 14).
4. Carefully remove the pre-cleaner (D, Figure 14) and the filter (C) from the air filter
base (F).
5. To loosen debris, lightly tap the filter (C, Figure 14) on a hard surface. If the filter is
dirty, replace it with a new filter.
6. Remove the pre-cleaner (D, Figure 14) from the filter (C).
7. Clean the pre-cleaner (D, Figure 14) in liquid detergent and water. Let the pre-
cleaner fully air dry. Do not lubricate the pre-cleaner.
8. Assemble the dry pre-cleaner (D, Figure 14) to the filter (C).
9. Install the filter (C, Figure 14) and the pre-cleaner (D) to air filter base (F) and onto
the stud (G). Make sure the filter is correctly assembled to the air filter base with a
fastener (E).
10. Install the cover (B, Figure 14) with the fastener(s) (A). Make sure 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 Strainer, if installed
1. Remove the fuel cap (A, Figure 15).
2. Remove the fuel strainer (B, Figure 15).
3. If the fuel strainer is dirty, clean or replace it. If you replace the fuel strainer, make
sure to use an original equipment replacement fuel strainer.
