Servicing The Spark Plug - Briggs & Stratton 130000 Manual Del Operador

1
Clean more frequently in dusty conditions or when many particles are in the air.
2
Not necessary unless engine performance problems occur.
Carburetor and Engine Speed
Do not make adjustments to the carburetor, governor spring, linkages, or other parts
to adjust the engine speed. If adjustments are necessary, contact a Briggs & Stratton
Authorized Service Dealer for servicing.
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 13) 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.
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.
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 14), and
keep it away from the spark plug (E).
2. Remove the oil drain plug (F, Figure 15). Drain the oil into an approved container.
NOTE: All of the oil drain plugs (G, Figure 15) can be installed in the engine.
3. Install and tighten the oil drain plug (F, Figure 15).
Add Oil
• Make sure that the engine is level.
• Clean the oil fill area of debris.
• See the Specifications section for oil capacity.
Short Dipstick, if installed
1. Remove the dipstick (A, Figure 16). Use a cloth to remove oil from the dipstick.
2. Install the dipstick (A, Figure 16). Do not turn or tighten the dipstick.
3. Remove the dipstick and check the oil level. The correct oil level is at the top of the
full indicator (B, Figure 16) on the dipstick.
4. If the oil level is low, slowly add oil into the engine oil fill (C, Figure 16). Do not add
too much oil. Wait one minute and check the oil level again. Make sure that the oil
level is correct.
5. Install and tighten the dipstick (A, Figure 16).
Extended Dipstick, if installed
1. Remove the dipstick (A, Figure 17). Use a cloth to remove remaining oil from the
dipstick.
2. Install the dipstick (A, Figure 17). Do not turn or tighten the dipstick..
3. Remove the dipstick and check the oil level. The correct oil level is at the top of the
full indicator (B, Figure 17) on the dipstick.
4. If the oil level is low, slowly add oil into the engine oil fill (C, Figure 17). Do not add
too much oil. Wait one minute and check the oil level again. Make sure that the oil
level is correct.
5. Install and tighten the dipstick (A, Figure 17).
6. Connect the spark plug wire to the spark plug. Refer to the Remove Oil section.
Change Gear Reduction Oil
Some engines are equipped with a Gear Reduction Unit. If equipped, refer to the steps
for one of the Gear Reduction Units that follow.
2:1 Chain Reduction Unit
If the engine is installed with a 2:1 chain reduction unit (G, Figure 18), an oil change is
not necessary. The oil in the engine also lubricates the chain reduction unit.
6:1 Gear Reduction Unit
If your engine is equipped with a 6:1 gear reduction unit, do the steps that follow:
1. Remove the oil fill plug (A, Figure 19) and the oil level plug (B).
2. Remove the oil drain plug (C, Figure 19) and drain the oil into an approved
container.
3. Install and tighten the oil drain plug (C, Figure 19).
4. Slowly add gear reduction oil (80W-90) into the oil fill hole (D, Figure 19). Continue
to add the gear reduction oil (80W-90) until the oil comes out of the oil level hole
(E).
5. Install and tighten the oil level plug (B, Figure 19).
6. Install and tighten the oil fill plug (A, Figure 19).
NOTE: The oil fill plug (A, Figure 19) has a vent hole (F) and must be installed on the
top of the gear case cover as shown.
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 servicing requirements.
Different models will use a foam or a paper filter. Some models could also have an
optional pre-cleaner that can be cleaned 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) (A, Figure 20).
2. Remove the cover (B, Figure 20).
3. Remove the fastener (E, Figure 20).
4. Carefully remove the pre-cleaner (D, Figure 20) and the filter (C) from the air filter
base (F).
5. To loosen debris, lightly tap the filter (C, Figure 20) on a hard surface. If the filter is
dirty, replace it with a new filter.
6. Remove the pre-cleaner (D, Figure 20) from the filter (C).
7. Clean the pre-cleaner (D, Figure 20) 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 20) to the filter (C).
