Starting

WARNING

Carbon Monoxide can cause severe nausea, fainting or death.

Avoid inhaling exhaust fumes.

Engine exhaust gases contain poisonous carbon monoxide. Carbon monoxide is odorless, colorless, and can cause death if inhaled.

WARNING

Rotating Parts can cause severe injury.

Stay away while engine is in operation.

Keep hands, feet, hair, and clothing away from all moving parts to prevent injury. Never operate engine with covers, shrouds, or guards removed.

NOTE: Over priming may make it difficult to start engine. It is usually not necessary to prime a warm engine.

NOTE: Choke position for starting may vary depending upon temperature and other factors. Once engine is running and warm, turn choke to OFF position.

NOTE: Extend starter cord periodically to check its condition. If cord is frayed have it replaced immediately by a Kohler authorized dealer.

1.Turn fuel shut-off valve to ON position

(if equipped).

2.Turn engine on/off switch to ON position (if equipped).

3.Start engine as follows:

a.Primer Bulb Models: Place finger or thumb on center of primer bulb. Push primer 3 times.

or

b.Manual Choke Models:

Cold engine: Place throttle control to FAST position. Pull choke control into CHOKE/ON position.

Warm engine: place throttle control to RUN/FAST position.

or

c.Smart-Choke™ Models: this feature automatically adjusts choke on start-up.

4.Retractable Start: Slowly pull starter handle until just past compression-STOP! Return starter handle; firmly pull straight out to avoid excessive rope wear from starter rope guide.

Electric Start: Key switch (refer to operating instructions of equipment that this engine powers).

5.Gradually return choke control to OFF position after engine starts and warms up. Engine/equipment may be operated during warm up period, but it may be necessary to leave choke partially on until engine warms up.

Cold Weather Starting Hints

1.Use proper oil for temperature expected.

2.Disengage all possible external loads.

3.Use fresh winter grade fuel. Winter grade fuel has higher volatility to improve starting.

Stopping

1.If possible, remove load by disengaging all PTO driven attachments.

2.If equipped, move throttle control to slow or idle position; stop engine.

3.If equipped, close fuel shut-off valve.

Angle of Operation

Refer to operating instructions of equipment this engine powers. Do not operate this engine exceeding maximum angle of operation; see specification table. Engine damage could result from insufficient lubrication.

Engine Speed

NOTE: Do not tamper with governor setting to increase maximum engine speed. Overspeed is hazardous and will void warranty.

High Altitude Operation

This engine may require a high altitude carburetor kit to ensure correct engine operation at altitudes above 4000 ft.

(1219 meters). To obtain high altitude kit information or to find a Kohler authorized dealer visit KohlerEngines.com or call 1-800-544-2444 (U.S. and Canada).

This engine should be operated in its original configuration below 4000 ft. (1219 meters) as damage may occur if high altitude carburetor kit is installed and operated below 4000 ft. (1219 meters).
