General Safety Precautions
A. Avoid Carbon Monoxide Poisoning
All engine exhaust contains carbonmonoxide,adeadlygas. Breathingcarbonmonoxidecan 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-ventilatedareas.Ifyouexperienceanysymptoms ofcarbonmonoxidepoisoning,leavetheareaimmediately, 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 ventilateengineexhaustwithfansoropenwindows 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.
•NEVERrunengineoutdoorswhereengineexhaust 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 andbeignitedbyasparkorflamemanyfeet awayfromengine.Topreventinjuryordeath 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
andspaceheaters,clothesdryers,electricmotors, etc.
•NEVER remove fuel cap or add fuel when engine is running.
•NEVER start or operate the engine with 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 recommendspurchasinggasolineincontainerswith 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.
C.AdultSupervisionofOperation,Refueling and Maintenance
Not everyone who is allowed to use an engine is capable of safely and responsibly operating, maintaining and/or fueling it. TecumsehPower recommends the following:
•An adult should fuel the engine. NEVER allow children to refuel an engine.
•Anadultshouldperformmaintenanceonanengine. Only allow children to perform maintenance if an adult has determined they are experienced and capable of such operation.
•Anadultshouldstarttheengine.Onlyallowchildren to start the engine if an adult has determined they are experienced and capable of such operation.
Toavoidunsupervisedoperationoftheengine,especially by children, NEVER leave it unattended when it is running.
D. Stay Away from Rotating Parts
NEVER operate an engine with an unguarded engine shaft.
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 rotatingparts,leadingtoseriousinjuryor death. To avoid serious injury or death, be sure the flywheel guard is in place.

Reviewing The Engine ID Label
Effective with the 2004 Model Year, we have changes to the engine I.D. label on our products. The following pages will explain the information contained on the label dependent on the age of your product.
Specification Number
The numbers following the model number make up the specification number.
Using model LV195EA-361541B, as an example, interpretation is as follows:
LV195EA-361541B is the model and specification number.

Warranty Code
Is the specification number used for properly identifying the parts of the engine
Indicates a standard power configuration Indicates EPA/CARB compliant
Indicates a 195 cc displacement
Indicates a vertical shaft configuration
Indicates an L-Head, side valve configuration
Date of Manufacture
The Date of Manufacture (D.O.M.) indicates the production date.
For this example, 03188BC0010 is the D.O.M. (Date of Manufacture).
