How To Service The Air Filter - Figure 8
WARNING
Gasoline and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
Never start or run the engine with the air cleaner assembly or the air filter removed.
•
CAUTION: 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 or oval cartridge. 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 pre-cleaner (B), if equipped, and the filter (C).
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.
Oval Air Filter
1. Remove the cover (A, Figure 9).
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.

CAUTION: Do not use water to clean the engine. Water could contaminate the fuel
9 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 11).
Storage
When Storing Gasoline 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 FRESH START
drip concentrate cartridge.
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. The engine and fuel can then be stored up to 24 months.
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.
