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 Exhaust and Cooling Systems
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.
This is an air cooled engine. Dirt or unwanted material can prevent air flow and cause
the engine to become too hot. This results in unsatisfactory performance and decreases
the life of the engine. The cylinder cooling fins can collect unwanted material that cannot
be remove without partial disassembly of the engine. Make sure that a Briggs & Stratton
Authorized Service Dealer examines and cleans the air cooling system. Refer to the
Maintenance Schedule.
1. Make sure that no combustible materials are around and behind the muffler.
2. Use a brush or dry cloth to remove all unwanted material from the blower housing
cover, muffler and cylinder area. DO NOT use water to clean the engine.
3. Make sure that the linkage, springs, and controls are clean.
4. Examine the muffler for cracks, corrosion, or other damage.
5. Remove the deflector or the spark arrester, if installed, and examine for damage or
carbon blockage. Make sure that you clean or install the replacement parts before
you operate the equipment.
6. If Installed, make sure that the oil cooler fins are clean.
Servicing the Spark Plug
Check the spark plug gap (A, Figure 15) 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.
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 engine off but warm, disconnect the spark plug wire(s) (D, Figure 16) and keep
it away from the spark plug(s) (E).
2. Remove the oil drain plug (F, Figure 17). Drain the oil into an approved container.
NOTE: All of the oil drain plugs (F, Figure 17) can be installed in the engine.
3. Install and tighten the oil drain plug (F, Figure 17)
4. When you drain the oil from the top oil fill tube (C, Figure 18), 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 5). Remove oil from the dipstick with a clean cloth.
2. Slowly add oil into the engine oil fill (C, Figure 5). Do not put too much oil in the
engine oil fill. Wait one minute and then check the oil level.
NOTE: Do not add oil at the quick oil drain, if equipped.
3. Install and tighten the dipstick (A, Figure 5).
4. Remove the dipstick and check the oil level. The correct oil level is at the top of the
full indicator (B, Figure 5) on the dipstick.
5. Install and tighten the dipstick (A, Figure 5).
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 use either a foam or a paper filter. Some models can 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.
1. Loosen the fastener(s) (A, Figures 19, 20).
2. Remove the cover (B, Figures 19, 20), if equipped.
3. Remove the fastener(s) (E, Figure 20), if equipped.
4. To make sure debris does not enter the carburetor, remove the pre-cleaner (D,
Figures 19, 20), and the filter (C) from the air filter base.
5. To loosen debris, lightly tap the filter (C, Figures 19, 20) on a hard surface. If the air
filter is dirty, replace it with a new filter.
6. Remove the pre-cleaner (D, Figures 19, 20) from the filter (C).
7. Clean the pre-cleaner (D, Figures 19, 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, Figures 19, 20) to the filter (C).
9. Install the filter (C, Figures 19, 20) and the pre-cleaner (D). Make sure the filter is
installed correctly on the air filter base.
10. Make sure the gasket (F, Figure 20), if equipped, is in the correct position under the
filter (C). Attach the filter (C) with fastener(s) (E), if equipped.
11. Install the cover (B, Figures 19, 20) 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.
• If fuel spills, wait until it dries before you start the engine.
