Congratulations –

 You have selected a fine four-cycle, single cylinder, air-cooled engine. Kohler designs long

life strength and on-the-job durability into each engine…making a Kohler engine dependable…dependability you

can count on. Here are some reasons why:

• Kohler engines are easy to service. All routine service areas (like the dipstick and oil fill, air cleaner, spark

plug, and carburetor) are easily and quickly accessible.

• Parts subject to the most wear and tear (like the cylinder, crankshaft, and camshaft) are made from

precision formulated cast iron. Because the cast iron cylinder can be rebored, these engines can last even

longer.

• Dependable, maintenance-free electronic ignition system ensures fast, easy starts time after time.

• Every Kohler engine is backed by a worldwide network of over 10,000 distributors and dealers. Service

support is just a phone call away. Call 1-800-544-2444 (U.S. & Canada) for Sales & Service assistance.

To keep your engine in top operating condition, follow the maintenance procedures in this manual.
