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 (A) (Figure 18). Keep
linkage, springs and controls (B) clean. Keep the area around and behind the muffler (C)
free of any combustible debris.
Storage
WARNING
Gasoline and its vapors are extremely flammable and explosive.
Fire or explosion can cause severe burns or death.
When Storing Gasoline Or Equipment With Fuel In Tank
• Store away f rom furnaces, stoves, water heaters or other appliances that have
pilot lights or other ignition sources because they can ignite gasoline 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 FRESH START
®
fuel stabilizer, available as a liquid additive or a
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.
