AIR INDEX
To show compliance with California emission regulations, a hangtag has been provided
displaying the Air Index level and durability period of this engine.
The Air Index level defi nes how clean an engine’s exhaust is over a period of time. A bar
graph scaled from “0” (most clean) to “10” (least clean) is used to show an engine’s Air Index
level. A lower Air Index level represents cleaner exhaust from an engine.
The period of time (in hours) that the Air Index level is measured is known as the durability
period. Depending on the size of the engine, a selection of time periods can be used to
measure the Air Index level (see below).
Descriptive Term Applicable to Emissions Durability Period
Moderate 50 hours (engine from 0 to 80 cc)
125 hours (engine greater than 80 cc)
Intermediate 125 hours (engine from 0 to 80 cc)
250 hours (engine greater than 80 cc)
Extended 300 hours (engine from 0 to 80 cc)
500 hours (engine greater than 80 cc)
Notice: This hangtag must remain on this engine or piece of equipment, and only be
removed by the ultimate purchaser before operation.

all receipts covering maintenance on your engine, but
ROBIN AMERICA cannot deny warranty solely for the

ROBIN AMERICA may deny warranty coverage if your
engine or part has failed due to abuse, neglect, improper
maintenance or unapproved modifi cations.
You are responsible for presenting your engine to the
nearest service dealer authorized by ROBIN AMERICA

SAFETY PRECAUTIONS
!
The safety alert symbol ( ) is used with a signal
word (DANGER, CAUTION, WARNING), a pictorial
and/or a safety message to alert you to hazards.
DANGER indicates a hazard which, if not avoided,
will result in death or serious injury. WARNING indicates a hazard which, if not avoided, could result
in death or serious injury. CAUTION indicates a
hazard which, if not avoided, might result in minor
or moderate injury. NOTICE indicates a situation
that could result in engine damage. Follow safety
messages to avoid or reduce the risk of injury or
death.
The manufacturer cannot possibly anticipate every
possible circumstance that might involve a hazard.
The warnings in this manual, and the tags and
decals affi xed to the unit are, therefore, not all-
inclusive. If you use a procedure, work method or
operating technique that the manufacturer does not
specifi cally recommend you must satisfy yourself
that it is safe for you and others. You must also
make sure that the procedure, work method or operating technique that you choose does not render
the engine system unsafe.

Running engine gives off carbon
monoxide, and odorless, colorless,
poison gas.
Breathing carbon monoxide can
cause headache, fatigue, dizziness, vomiting, confusion, seizures, nausea, fainting or death.

WARNING
!
WARNING
▲
Propane and Natural Gas are
extremely fl ammable and explo-
sive.
Fire or explosion can cause
severe burns or death.
• Install the fuel supply system according to
applicable fuel-gas codes.
• Before placing the engine into service, the fuel
system lines must be properly purged and leak
tested. Procedures used in gaseous fuel leak-
age tests must comply strictly with applicable
fuel gas codes.
• DO NOT use fl ame or any source of heat to test
for gas leaks.
• NO leakage is permitted.
• LP gas is heavier than air and will settle in low
areas.
• Natural gas is lighter than air and will collect in
high areas.
• DO NOT operate engine if smell of fuel is
present or other explosive conditions exist.
• The slightest spark can ignite these fuels and
cause an explosion.
• DO NOT smoke around the engine. Wipe up
any oil spills immediately. Keep the area near
the engine clean and free of debris.
• Operate engine ONLY outdoors.
• Keep exhaust gas from entering a confi ned
area through windows, doors, ventilation
intakes, or other openings.

SAFETY PRECAUTIONS
Please make sure you review each precaution carefully.
EXHAUST PRECAUTIONS
• Never inhale gas.
It contains carbon monoxide, a colorless,
orderless and extremely dangerous gas
which can cause unconsciousness
or death.
• Never operate the engine indoors or in
a poorly ventilated area, such as tunnel,
cave, etc.
• Exercise extreme care when operating
the engine near people or animals.
• Keep the exhaust pipe free of foreign
objects.
REFUELING PRECAUTIONS
• Be sure to stop the engine prior to connecting a fuel line. Refuel outdoors, in a
well-ventilated area.
• Use only approved LP/NG fuel hose and connectors.
• Check for fuel leaks before operating the engine
.
FIRE PREVENTION
• LPG is extremely fl ammable and combustible, and so is NATURAL gas.
• Do not operate while smoking or near an open fl ame.
• Do not use around dry brush, twigs, cloth rags, or other fl ammable materials.
• Keep the engine at least 3 feet (1 meter)
away from buildings or other structures.
• Keep the engine away from fl ammables
and other hazardous material (trash, rags,
lubricants, explosives).
• DO not leave cigarettes, sparks and
fl ames near by any fuel-related parts.
• Never smoke near LPG or Natural gas
and keep other fl ames and sparks away.
• In order to reduce the risk of the fi re or
explosion, be careful when working
around LPG or Natural gas.
8
PROTECTIVE COVER
• Place the protective covers over the
rotating parts.
If rotating parts such as the drive shaft,
pulley, belt, etc. are left exposed, they
are potentially hazardous.
To prevent injury, equip them with
protective covers or shrouds.
• Be careful of hot parts.
The muffl er and other engine parts
become very hot while the engine is
running or just after it has stopped.
Operate the engine in a safe area and
keep children away from the running
engine.
• Never make adjustments on the
machinery while it is connected to the
engine, without fi rst removing the ignition
cable from the spark plug. Turning the
crankshaft by hand during adjusting
or cleaning might start the engine, and the
machinery with it, causing serious injury to
the operator.
• Never run the engine with governor
disconnected, or operate at speeds in
excess of 3600 rpm load.
SURROUNDINGS
• Operate the engine on a stable, level
surface free of small rocks, loose gravel,
etc.
NOTE
Operating the engine at a steep
incline may cause seizure due to
improper lubrication even with a
maximum oil level.
