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.
Foam Air Filter
1.
Loosen or remove the fastener(s) (A, Figure 14), if installed.
2.
Open or remove the cover (B, Figure 14).
3.
Carefully remove the foam element (C, Figure 14) from the air filter base.
4.
Clean the foam element (C, Figure 14) in liquid detergent and water. Compress the
foam element with your hands in a clean cloth until it is dry.
5.
Soak the foam element (C, Figure 14) 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 14) onto the air filter base.
7.
Close or install the cover (B, Figure 14) 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 15).
2.
Open or remove the cover (B, Figure 15).
3.
Carefully remove the pre-cleaner (D, Figure 15) and the filter (C) from the air filter
base.
4.
Remove the pre-cleaner (D, Figure 15), if installed, from the filter (C).
5.
To loosen all unwanted material, lightly tap the filter (C, Figure 15) on a hard
surface. If the filter is very dirty, replace with a new filter.
6.
Clean the pre-cleaner (D, Figure 15), if installed, in liquid detergent and water.
Make sure that pre-cleaner is fully dry. Do not add oil to the pre-cleaner.
7.
Assemble the dry pre-cleaner (D, Figure 15), if installed, to the filter (C).
8.
Install the filter (C, Figure 15) and the pre-cleaner (D) onto the air filter base. Make
sure that the filter is tightly on the air filter base.
9.
Close or install the cover (B, Figure 15) and attach 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.
•
If fuel spills, wait until it dries before you start the engine.
Fuel Filter, if installed
1.
Before you replace the fuel filter (A, Figure 16), drain the fuel tank or close the fuel
shut-off valve. If the fuel tank is not drained, fuel leakage can occur and cause a fire
or explosion.
2.
Squeeze the tabs (B, Figure 16) on the clamps (C) with pliers. Move the clamps
away from the fuel filter (A).
3.
Twist and pull the fuel lines (D, Figure 16) off of the fuel filter.
4.
Examine the fuel lines (D, Figure 16) for cracks or leaks. If it is necessary, replace
the fuel lines.
5.
Replace the fuel filter (A, Figure 16).
6.
Attach the fuel lines (D, Figure 16) with clamps (C).

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 17). 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 6) 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 to the
specified instructions by the manufacturer. 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 is out of fuel.
Engine Oil
While the engine is still warm, change the engine oil. Refer to Change the Engine Oil
section.

Service Parts
Purchase Briggs & Stratton service parts at
shop.briggsandstratton.com/parts or find an Authorized Service
Dealer at BRIGGSandSTRATTON.COM. You will need your
identification number (model - type - trim). Refer to the Features and
Controls section to find your engine identification number.
Power Ratings
The gross power rating for individual gasoline engine models is labeled in accordance
with SAE (Society of Automotive Engineers) code J1940 Small Engine Power & Torque
Rating Procedure, and is rated in accordance with SAE J1995. Torque values are
derived at 2600 RPM for those engines with "rpm" called out on the label and 3060 RPM
for all others; horsepower values are derived at 3600 RPM. The gross power curves
can be viewed at www.BRIGGSandSTRATTON.COM. Net power values are taken with
exhaust and air cleaner installed whereas gross power values are collected without
these attachments. Actual gross engine power will be higher than net engine power and
