II. Special Information for Users

Installing an Engine

If you purchased this engine

separately with the intention of installing it on a recreational vehicle, ensure that the vehicle is designed or is retrofitted to be used specifically with this Tecumseh Power Sport engine. If you use an improper, nonapproved and/or wrong sized engine, there is a potential for serious injury or death from:

• operation at unsafe speeds or a runaway vehicle,

• improper fit and operation of guards, electrical wiring, throttle cable, clutch, torque converter, etc.

III. Engine Model Applications

I. General Safety Precautions

B. Avoid Gasoline Fires

WARNING

Read equipment manufacturer’s manual and this material thoroughly before using this engine. Failure to do so can result in serious injury or death. Call Tecumseh Power Company at 1-800-558-5402 or visit www.TecumsehPower.com if you have any questions.

A. Avoid Carbon Monoxide Poisoning

All engine exhaust contains carbon monoxide, a deadly gas. Breathing carbon monoxide can cause headaches, dizziness, drowsiness, nausea, confusion and eventually death.

Carbon monoxide is a colorless, odorless, tasteless gas which may be present even if you do not see or smell any engine exhaust. Deadly levels of carbon monoxide can collect rapidly and you can quickly be overcome and unable to save yourself. Also, deadly levels of carbon monoxide can linger for hours or days in enclosed or poorly-ventilated areas. If you experience any symptoms of carbon monoxide poisoning, leave the area immediately, get fresh air, and SEEK MEDICAL TREATMENT.

To prevent serious injury or death from carbon monoxide:

• NEVER run engine indoors. Even if you try to ventilate engine exhaust with fans or open windows and doors, carbon monoxide can rapidly reach dangerous levels.

Gasoline (fuel) vapors are highly flammable and can explode. Fuel vapors can spread and be ignited by a spark or flame many feet away from engine. To prevent injury or death from fuel fires, follow these instructions:

• NEVER store engine with fuel in fuel tank inside a building with potential sources of ignition such as hot water and space heaters, clothes dryers, electric motors, etc.

• NEVER add fuel with engine running.

• NEVER start or operate the engine with the fuel fill cap removed.

• Allow engine to cool before refueling.

• NEVER fill fuel tank indoors or in an enclosed area such as a garage, barn shed, etc. Fill fuel tank outdoors in a well-ventilated area.

• DO NOT smoke while refueling tank.

• Use only an approved red GASOLINE container to store and dispense fuel. Tecumseh recommends purchasing gasoline in containers with a capacity of

2.5 gallons or less. Small containers are easier to handle and help eliminate spillage during refueling.

• DO NOT pour fuel from engine or siphon fuel by mouth. To empty the fuel tank see "I. Draining Fuel" instructions on page 26.

• NEVER run engine in poorly-ventilated or partially enclosed areas such as barns, garages, basements, carports, under dwellings, or in pits.

• NEVER run engine outdoors where engine exhaust can be drawn into a building through openings such as windows and doors.

C. Adult Supervision of Operation, Refueling

and Maintenance

The manufacturer of the recreational vehicle may provide information about who is allowed to operate or ride in the vehicle (see equipment manufacturer’s manual). Not everyone who is allowed to operate or ride in the vehicle is capable of safely and responsibly operating, maintaining and/or fueling this Tecumseh Power Sport Engine. Tecumseh recommends the following:

• An adult should fuel this engine. NEVER allow children to refuel this engine. See "D. Filling Fuel Tank" instructions on page 8.

• An adult should perform maintenance on this engine. See "VIII. Maintenance" instructions on page 18. Only allow children to perform maintenance if an adult has determined they are experienced and capable of such operation.

• An adult should start the engine. See "G. Avoid Accidental Starts" instructions on page 3 and "A. Engine Pre-Ride Checklist" instructions on page 6. Only allow children to start the engine if an adult has determined they are experienced and capable of such operation.

Figure 1. DO NOT use Without Engine Shaft Guard

To avoid unsupervised operation of the recreational vehicle, especially by children, NEVER leave the engine unattended when it is running.

D. Stay Away from Rotating Parts

NEVER operate the engine with an unguarded engine shaft. See Figure 1.

The equipment manufacturer attaches a sprocket and chain or pulley and belt to the engine shaft. If these parts are not properly guarded, or if you are not sure whether they are properly guarded, DO NOT use your recreational vehicle; contact the equipment manufacturer. Hands, feet, hair, jewelry, clothing, etc. can become entangled in rotating parts, leading to serious injury or death. To avoid serious injury or death, be sure the flywheel guard is in place. See Figure 2.

E. Do Not Modify Engine

To avoid serious injury or death, DO NOT modify engine in any way. Tampering with the governor setting can lead to a runaway vehicle and cause the engine to operate at unsafe speeds. NEVER tamper with factory setting of engine governor.

P O T S

1. Muffler Guard

2. Flywheel Guard

Figure 2. Typical Engine Guard Locations

F. Avoid Burns and Fire from Hot Surfaces

The muffler and other engine parts become extremely hot during operation and remain hot after the engine has stopped.

• To avoid severe burns on contact, NEVER operate the engine without the muffler guard in place, see Figure 2 and avoid hot areas of the engine.

• To reduce the risk of fire keep all materials that can burn, including grass and leaves, away from muffler and rest of engine. DO NOT operate, idle or park the recreational vehicle in long dry grass or other dry ground cover.

G. Avoid Accidental Starts

To prevent accidental starting when working on equipment always:

• Disconnect spark plug wire and keep it away from spark plug. See Figure 3.

• Keep the disconnected spark plug wire securely away from metal parts where arcing could occur.

• Attach the spark plug wire to the grounding post, if provided. See Figure 4.

• Disconnect battery at negative terminal first, if engine is equipped with an electric starter.

• Turn off all engine switches.

• Remove ignition key, if provided.

H. Use Hearing Protection

Engine noise may cause hearing damage. Always wear hearing protection when operating a recreational vehicle engine.

IV. Before Starting Your Engine

A. Engine Pre-Ride Checklist

WARNING

To avoid serious injury or death,

always complete both the engine and equipment manufacturer’s pre-ride checklist before using the engine. This engine should NEVER be used if you identify a problem with any of the steps listed below.

Be sure the engine is turned off for steps 1 thru 4:

1. Fuel cap—Check that the anti-splash fuel fill cap is

securely in place.

2. Guards—Check that all of the guards are securely in

place. NEVER operate the vehicle if you think there may be a guard missing. Check with equipment manufacturer for a complete list of guards. See Figure 7 and Figure 8. See "D. Stay Away from Rotating Parts" instructions on page 2.

3. Debris—Check that engine, controls and guards are

free from debris, snow or ice. For debris removal areas, see "B. Removing Debris From Engine" instructions on page 20.

4. Throttle—With the engine off, check that the gas pedal

operates smoothly and returns to an idle position when released.

WARNING

An adult should start the engine. Only

allow children to start engine if an adult has determined they are experienced and capable of such operation.

5. Idle speed—Be sure that operator is in place with the

brake engaged before starting the engine. Start the engine and slowly release the brake. Check that the vehicle does not move when the engine is idling. If it does move at idle, stop the vehicle and shut off the engine. The vehicle requires service and should not be operated.
