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.

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.
