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 19). Keep
linkage, springs and controls (B) clean. Keep the area around and behind the muffler (C)
free of any combustible debris.

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.
For engines equipped with a FRESH START
®
START available in 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 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.
