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. TecumsehPower
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. TecumsehPower 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.

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.
