I. General Safety Precautions

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. Consult your local Authorized TecumsehPower Servicing Dealer, call 1-800-558-5402, or go to www.TecumsehPower.com for additional information.

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.

• 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.

B. Avoid Gasoline Fires

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 remove fuel fill cap or add fuel when engine is running.

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

• Allow engine to cool before refueling.

• NEVER fill fuel tank indoors. 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. TecumsehPower Company 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. T o empty the fuel t ank, see "I. Draining Fuel" instructions on page 24.

C. Adult Supervision of Operation, Refueling

and Maintenance

The manufacturer of the equipment may provide information about who is allowed to use this engine (see equipment manufacturer’s manual). NOT everyone who is allowed to use this engine is capable of safely and responsibly operating, maintaining and/or fueling it. TecumsehPower Company recommends the following:

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

• An adult should perform maintenance on this engine. See "VII. Maintenance" instructions on page 17. 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 2. Only allow children to start the engine if an adult has determined they are experienced and capable of such operation.

• To avoid unsupervised operation of the engine, especially by children, NEVER leave it unattended when it is running. Remove ignition key, if equipped.

D. Stay Away from Rotating Parts

NEVER operate the engine with an unguarded engine shaft or flywheel. See Figure 1 on page 2.

The equipment manufacturer may attach 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 engine; 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 1 on page 2.

181-1275-14 4-Cycle • Snow King Engine Page 1

E. DO NOT Modify Engine

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

WARNING

Use of this engine on fun-carts, go-kar ts, or m ini-bikes can result in serious injury or death. TecumsehPower Company manufactures the Power Sport line of engines for use in such applications. Consult your local Authorized TecumsehPower Servicing Dealer, call 1-800-558-5402, or visit www.TecumsehPower .com for additional information.

Figure 1. Typical Flywheel Guard Location

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, STAY AWAY from hot areas of engine. DO NOT operate the engine without the muffler guard in place, if equipped. TecumsehPower Company offers a muffler guard for all 4-Cycle Snow King Engines. Consult your local Authorized TecumsehPower Servicing Dealer or call 1-800-558-5402 for additional information. See Figure 2.

• 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 engine powered equipment in long dry grass or other dry ground cover.

G. Avoid Accidental Starts

To prevent accidental starting when working on equipment always:

OH195SA/OH195SP

LH318SA/LH358SALH195SA/LH195SP

• Carefully disconnect spark plug wire and keep it away from spark plug. See Figures 3 and 4.

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

• Carefully attach the spark plug wire to the grounding post, if provided.

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

• Turn all engine switches to “OFF” position.

• Remove ignition key, if provided.

A. Oil

To operate your engine you need to use a clean, high quality, detergent oil. For recommended engine oil, see Table 1. In addition, you need to be sure the oil sump contains the correct amount of oil to operate properly. For recommended oil sump capacity, see Table 2.

NOTES

Be sure original container is marked A.P.I. Service “SL/SJ”. Using multigrade oil above 32°F (0°C) will increase oil

consumption. SAE 10W40 is NOT recommended. Special-formulated oils are available at your Authorize d

B. Fuel

Use unleaded regular, unleaded premium or reformulated automotive fuel only. You may use gasoline containing the components identified in Table 3.

• DO NOT use leaded fuel.

• Fuel must be fresh and clean. NEVER use fuel left over from last season or stored for long periods.

• NEVER mix oil with fuel.

• DO NOT use fuel containing Methanol (Wood Alcohol).

CAUTION

The use of alternative fuels such as E85

or E20 are NOT recommended for use in TecumsehPower engines. Alternative fuels with high alcohol content can cause hard starting, poor engine performance, and may cause internal engine damage.

NOTE Damage and/or performance problems that occur fro m use of fuels other than those listed in the Operator’s Manuals will not be considered warranty.

IV. Before Starting Your Engine

A. Checking Oil Level

To avoid engine damage, it is important to:

• Check oil level before each use and every 5 operating hours when engine is warm. Check oil level more frequently during engine break-in.

• Keep oil level between “FULL” and “ADD” marks on oil fill cap/dipstick or to point of overflow on engines with an oil fill cap/plug. See Figure 7.

• Be sure oil fill cap/dipstick or oil fill cap/plug is tightened securely.
