How To Clean/Replace The Debris Strainer - Figure 14
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.
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. Remove the fuel cap (A, Figure 14).
2. Remove the debris strainer (B).
3. If the debris strainer is dirty, clean or replace it. If you replace the debris strainer,
make sure to use an original equipment replacement debris strainer.
How To Clean The Air Cooling System - Figure 15
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.

* Engine power will decrease 3.5% for each 1,000 feet (300 meters) above sea level and 1% for each 10 F (5.6 C) above 77 F (25 C). The engine will operate satisfactorily at an
angle up to 15. Refer to the equipment operator's manual for safe allowable operating limits on slopes.

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). Keep linkage,
springs and controls (B) clean. Keep the area around and behind the muffler (C) free of
any combustible debris (Figure 15).
After a period of time, debris can accumulate in the cylinder cooling fins and cause the
engine to overheat. This debris cannot be removed without partial disassembly of the
engine. Have a Briggs & Stratton Authorized Dealer inspect and clean the air cooling
system as recommended in the Maintenance Chart.
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 light or other ignition source 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,
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.
