WARNING
engine repair and maintenance. If you are unfamiliar with two and four cycle engine operation
and maintenance, DO NOT attempt any maintenance or repairs. Contact your local Tecumseh
Servicing Dealer for assistance.
IMPORTANT NOTICE!
Safety Definitions
Statements in this manual preceded by the following
words and graphics are of special significance:
Or
WARNING indicates a potentially hazardous situation
which if not avoided, could result in death or serious
injury.
NOTE
Refers to important information and is placed in italic
type.
It is recommended that you take special notice of all
items discussed on the next two pages and wear the
appropriate safety equipment.
Before operating an engine it is your responsibility to
read the Operator’s Manual. Follow these basic rules
for your personal safety:
Tecumseh Contact Information
For engine adjustments, repairs or warranty service,
contact your nearest Authorized Tecumseh Servicing
Dealer. Find them on our website at www.TecumsehPower.
com or call Tecumseh Power Company at 1-800-558-5402
or 262-377-2700 if you are located outside the U.S.
• Keep this manual handy at all times for
future reference.
• Read it carefully and familiarize yourself
with operating, maintenance, components
and safety instructions.
Notice Regarding Emissions
Engines which are certified to comply with California and
U.S. EPA emission regulations for SORE (Small Off Road
Equipment), are certified to operate on regular unleaded
gasoline, and may include the following emission control
systems: (EM) Engine Modification and (TWC) ThreeWay Catalyst (if so equipped).

General Safety Precautions
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 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. 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.
C. Adult Supervision of Operation, Refueling
and Maintenance
Not everyone who is allowed to use an engine is capable
of safely and responsibly operating, maintaining and/or
fueling it. Tecumseh recommends the following:
• An adult should fuel the engine. NEVER allow
children to refuel an engine.
• An adult should perform maintenance on an engine.
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. 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.
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
rotating parts, leading to serious injury or
death. To avoid serious injury or death,
be sure the flywheel guard is in place.

Model Numbering System for Current Tecumseh’s Full Engine Line
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.
L V 195 E A - 361541B (B)
{
{
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
{
Warranty Code
Is the specification number used
for properly identifying the parts of
the engine
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).
