Fire or explosion can cause severe burns or death.
Never start or run 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 can
damage the filter and solvents will dissolve the filter.
The air filter system uses either a flat, round, or oval air filter. Some models are also
equipped with a pre-cleaner that can be washed and reused.
Flat Air Filter
1. Remove the cover (A, Figure 8).
2. Remove the filter (C) and the pre-cleaner (B).
3. To loosen debris, gently tap the filter on a hard surface. If the filter is excessively
dirty, replace with a new filter.
4. Wash the pre-cleaner in liquid detergent and water. Then allow it to thoroughly air
dry. Do not oil the pre-cleaner.
5. Assemble the dry pre-cleaner and the filter into the engine base (D).
6. Install the cover.
Round or Oval Air Filter
1. Remove the cover (A, Figure 9, 10).
2. To remove the filter (B), lift the end of the filter.
3. Remove the pre-cleaner (C), if equipped, from the filter.
4. To loosen debris, gently tap the filter on a hard surface. If the filter is excessively
dirty, replace with a new filter.
5. Wash the pre-cleaner in liquid detergent and water. Then allow it to thoroughly air
dry. Do not oil the pre-cleaner.
6. Assemble the dry pre-cleaner to the filter.
7. Install the filter into the engine base (D) and push down until the filter snaps in place.

How To Replace The Fuel Filter - Figure 11
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
Keep fuel away from sparks, open flames, pilot lights, heat, and other ignition

sources.
Check fuel lines, tank, cap, and fittings frequently for cracks or leaks.

Replace if necessary.
Before replacing the fuel filter, drain the fuel tank or close the fuel shut-off valve.

Replacement parts must be the same and installed in the same position as the

original parts.
If fuel spills, wait until it evaporates before starting engine.

1. Before replacing the fuel filter (A, Figure 11), if equipped, drain the fuel tank or close
the fuel shut-off valve. Otherwise, fuel can leak out and cause a fire or explosion.

2. Use pliers to squeeze tabs (B) on the clamps (C), then slide the clamps away from
9 10
the fuel filter. Twist and pull the fuel lines (D) off of the fuel filter.
3. Check the fuel lines for cracks or leaks. Replace if necessary.
4. Replace the fuel filter with an original equipment replacement filter.

How To Clean The Air Cooling System - Figure 12


NOTICE: Do not use water to clean the engine. Water could contaminate the fuel
system. Use a brush or dry cloth to clean the engine.
This is an air cooled engine. Dirt or debris can restrict air flow and cause the engine to
overheat, resulting in poor performance and reduced engine life.
Use a brush or dry cloth to remove debris from the finger guard/rotating screen (A).
Keep linkage, springs and controls (B) clean. Keep the area around and behind the
muffler free of any combustible debris (Figure 12). Make sure the oil cooler fins (C) are
free of dirt and debris.
Storage
When Storing Fuel Or Equipment With Fuel In Tank

Fuel System
Fuel can become stale when stored over 30 days. Stale fuel causes acid and gum
deposits to form in the fuel system or on essential carburetor parts. To keep fuel fresh,
use Briggs & Stratton Advanced Formula Fuel Treatment & Stabilizer, available
wherever Briggs & Stratton genuine service parts are sold.
There is no need to drain gasoline from the engine if a fuel stabilizer is added according
to instructions. Run the engine for 2 minutes to circulate the stabilizer throughout the fuel
system before storage.
If gasoline in the engine has not been treated with a fuel stabilizer, it must be drained into
an approved container. Run the engine until it stops from lack of fuel. The use of a fuel
stabilizer in the storage container is recommended to maintain freshness.
Engine Oil
While the engine is still warm, change the engine oil. See the How To Change The Oil
section.

WARNING
Running engines produce heat. Engine parts, especially muffler,
become extremely hot.
Severe thermal burns can occur on contact.
Combustible debris, such as leaves, grass, brush, etc. can catch fire.
Allow muffler, engine cylinder and fins to cool before touching.
Remove accumulated debris from muffler area and cylinder area.
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
Store away from furnaces, stoves, water heaters or other appliances that have
pilot lights or other ignition sources because they can ignite fuel vapors.
