ENGINE SAFETY PRECAUTIONS
Warning Carbon Monoxide Poisoning
Engines give off carbon monoxide, an odorless, colorless,
poisonous gas. Carbon monoxide may be present even if you do
not smell or see any engine exhaust. Breathing carbon monoxide
can cause nausea, fainting or death, in addition to drowsiness,
dizziness and confusion. If you experience any of these
symptoms, seek fresh air and medical attention immediately.
If your product comes with a separate engine manual, be
sure to read and follow all safety and warning precautions
outlined there, in addition to any in this manual.
Preventing Carbon Monoxide Poisoning
• Always start and run engine outdoors. Do not start or run
engine in an enclosed area, even if doors or windows are open.
• Never try to ventilate engine exhaust indoors. Carbon
monoxide can reach dangerous levels very quickly.
• Never run engine outdoors where exhaust fumes may be
pulled into a building.
• Never run engine outdoors in a poorly ventilated area where
the exhaust fumes may be trapped and not easily taken
away. (Examples include: in a large hole or areas where hills
surround your working area.)
• Never run engine in an enclosed or partially enclosed area.
(Examples include: buildings that are enclosed on one or
more sides, under tents, car ports or basements.)
• Always run the engine with the exhaust and muer pointed
in the direction away from the operator.
• Always keep the throttle in the “slow” position when not in use.
• Never point the exhaust muer towards anyone. People
should always be many feet away from the operation of the
engine and its attachments.
• Do not change the engine governor settings or over-speed
the engine.
Gasoline Fires and Handling Fuel Safely
Use extra care in handling gasoline and other fuels. They are
ammable and vapors are explosive.
• When storing extra fuel be sure that it is in an appropriate
container and away from any re hazards.
• Prevent re and explosion caused by static electric discharge.
Use only nonmetal, portable fuel containers approved by the
Underwriter’s Laboratory (U.L.) or the American Society for
Testing & Materials (ASTM).
• Always ll fuel tank outside in a well ventilated area. Never
fill your fuel tank with fuel indoors. (Examples include:
basement, garage, barn, shed, house, porch, etc.) Never
ll tank near appliances with pilot lights, heaters, or other
ignition sources. If the fuel has to be drained, this should

YOUR WARRANTY RIGHTS AND OBLIGATIONS

stringent anti-smog standards the federal government. Ardisam will
warrant the emission control system on your engine for the periods of
time listed below provided there has been no abuse, neglect, modication or improper maintenance of your engine.
The emission control system includes all components whose failure
would increase the emissions of any regulated pollutant. These
components are listed in the emission-related parts list located in a
subsequent section of this emissions warranty statement. Ardisam
will repair your engine at no cost to you for diagnosis, replacement
parts and labor, should a warrantable condition occur.
MANUFACTURER’S WARRANTY COVERAGE:
The emission control system is warranted for two years. If, during such
warranty period, any emission-related part on your engine is found to
be defective in materials or workmanship, repairs or replacement will
be performed by an Ardisam Authorized Warranty Service Facility.
PURCHASER’S/OWNER’S WARRANTY RESPONSIBILITIES:
As the SORE purchaser/owner, you are responsible for the completion of all required maintenance as listed in your factory supplied
Manual(s). For warranty purposes, Ardisam recommends that you
retain all receipts covering maintenance on your SORE. However,
Ardisam cannot deny warranty solely because of the lack of receipts
or for your failure to ensure the completion of all scheduled maintenance.
As the SORE purchaser/owner, you should, however, be aware that
Ardisam may deny any and/or all warranty coverage or responsibility
if your SORE or a part/component thereof, has failed due to abuse,
neglect, improper maintenance or modications, or the use of counterfeit and/or “grey market” parts not made, supplied or approved by
Ardisam.
You are responsible for presenting your SORE to an Ardisam Authorized Warranty Service Facility as soon as a problem occurs. The warranty repairs should be completed in a reasonable amount of time,
not to exceed 30 days.
