How To Clean The Air Cooling System - Figure 9
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.

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 air intake grille (A, Figure 9). Keep
linkage, springs and controls (B) clean. Keep the area around and behind the muffler (C)
free of any combustible debris. Make sure that the oil cooler fins (D) are free of dirt and
debris.
How To Replace The Fuel Filter - Figure 10
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 10), 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
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.
5. Secure the fuel lines with the clamps as shown.
Storage
WARNING
Fuel and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
When Storing Fuel Or Equipment With Fuel In Tank
Store away from furnaces, stoves, water heaters or other appliances that have

pilot lights or other ignition sources because they can ignite fuel vapors.
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,
en
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.
