I. 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 exhaustwith 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
canbe drawninto a building throughopeningssuch
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.
• NEVERremovefuel fill cap or add fuelwhen 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.Toemptythefueltank,see"I. DrainingFuel"
instructions on page 26.
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.

recreational vehicle, especially by
children, NEVER leave the engine unattended when it is
running.Alwaysturnofftheenginebefore exiting thevehicle
and remove ignition key, if provided.
NEVER store engine with fuel in the
fuel tank inside a building with
potential sources of ignition such as hot water or space
heaters, clothes dryers, electric motors, etc. Doing so may
lead to an explosion resulting in death or serious injury.
VII. Transporting Your Recreational
Vehicle
NEVER transport this engine inside
another vehicle or in any enclosed
space if there is any gasoline in the tank. Fuel vapor or
spilled fuel may ignite leading to serious injury or death.
If there is fuel in the fuel tank, close the fuel shut-off valve, if
equipped, and transport the recreational vehicle in an open
vehicle, such as an open trailer or open bed of a pickup
truck.
If you DO NOT have an open vehicle and have to transport
the recreational vehicle in a closed vehicle, follow these
steps for emptying the fuel tank before transporting:
1. Empty fuel tank by using a commercially available
suction device designed for use with gasoline.
To avoid serious injury or death, DO
NOT pour fuel from engine or siphon
fuel by mouth.
2. Drain fuel into an approved red GASOLINE container,
being careful to avoid spilling.
3. Run the engine until remaining fuel is consumed.
NEVER leave the engine unattended
when it is running and NEVER run
engine in enclosed areas to avoid death or serious injury.
VIII. Maintenance
