NOTICE
FEDERAL EMISSION COMPONENT DEFECT WARRANTY and CALIFORNIA
EMISSION CONTROL WARRANTY are applicable to only those engines
complied with EPA (Environmental Protection Agency) and CARB (California
Air Resources Board) emission regulations in the U.S.A.
NOTICE
To the engines exported to and used in the countries other than the U.S.A.,
warranty service shall be performed by the distributor in each country in accordance with the standard Robin engine warranty policy as applicable.
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 defines 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 65 cc)
125 hours (engine greater than 65 cc)
Intermediate - 125 hours (engine from 0 to 65 cc)
250 hours (engine greater than 65 cc)
Extended - 300 hours (engine from 0 to 65 cc)
500 hours (engine greater than 65 cc)
Notice : This hangtag must remain on this engine or piece of equipment, and
only be removed by the ultimate purchaser before operation.

1. SAFETY PRECAUTIONS
Please make sure you review each precaution carefully.
EXHAUST PRECAUTIONS
■ Never inhale exhaust gas.
It contains carbon monoxide, a colorless, odorless 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 operat-
ing the engine near people or
animals.
■ Keep the exhaust pipe free of foreign
objects.
REFUELING PRECAUTIONS
■ Be sure to stop the engine prior to
refueling.
■ Do not overfill the fuel tank.
■ If fuel is spilt, wipe it away carefully
and wait until the fuel has dried
before starting the engine.
■ After refueling, make sure that the
fuel cap is secured to prevent
spillage.
FIRE PREVENTION
■ Do not operate while smoking or near
an open flame.
■ Do not use around dry brush, twigs,
cloth rags, or other flammable materials.
■ Keep the engine at least 3 feet
(1 meter) away from buildings or
other structures.
■ Keep the engine away from flamma-
bles and other hazardous materials
(trash, rags, lubricants, explosives).
− 1−
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 muffler 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 first 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.
− 2−
■ Drain the fuel when transporting
the engine.
■ Do not move the engine while in
operation when it has been
removed from the equipment.
■ Keep the unit dry (do not operate it in
rainy conditions).
PRE-OPERATION CHECKS
■ Carefully check fuel hoses and
connections for looseness and fuel
leakage. Leaking fuel creates a
potentially dangerous situation.
■ Check bolts and nuts for looseness.
A loose bolt or nut may cause serious engine trouble.
■ Check the engine oil daily and refill if
necessary.
■ Check the fuel level and refill if
necessary.
Do not overfill the tank.
■ Wear snug fitting working clothes
when operating the engine.
Loose aprons, towels, belt, etc., may
be caught in the engine or drive train,
causing a dangerous situation.

CHECK ENGINE OIL
(DAILY)
Before checking or refilling engine oil, be
sure the engine is not running and is
located on a stable, level surface.
■ If the oil level is below the lower level
line on the oil gauge, refill with the
proper oil (see table) to the upper
level.
OIL CAPACITY : 52.48 oz. (1.55 liter)
■ When filling oil in the engine, keep
the engine level and fill the oil up to
the upper mark of the oil gauge.
Measure the oil level with the oil
gauge plugged in position.
■ After an oil change, run the engine,
and recheck the oil level. The oil level
may drop a little as the oil fills the oil
filter. Fill the oil up to the upper mark
of the oil gauge.
■ Change oil if it is contaminated.
(See page 14 Maintenance Schedule.)

CHECK FUEL
FUEL PUMP
FUEL INLET
WARNING
Do not refuel while smoking, near
an open flame or other potential
hazards.
■ The fuel tank shall be provided sepa-
rately, because the engine is not
equipped with a fuel tank.
A fuel valve and fuel filter should be
connected between the fuel tank and
fuel pump.
Securely connect with fuel hoses to
the fuel pump to prevent leakage.
■ Fuel tank may be mounted up to .66
meters (2 feet) below the carburetor.
If the fuel tank is mounted above the
carburetor, a fuel shut off valve must
be connected between the fuel tank
and fuel pump. The fuel valve must
be shut off when the engine is not
operating to prevent fuel from
flooding the carburetor.
■ A serious accident may occur if the
fuel hose comes off. Properly secure
the fuel line connections by
completely inserting the hose onto
the fittings and securing the
connection with a hose clamp.
■
Use automotive unleaded gasoline only.
This engine is certified to operate on
automotive unleaded gasoline.

Is there enough compression?
If the spark plug is loose, tighten it.
Is the spark plug wet with gasoline?
1. Choke (close choke lever) and slowly start the engine for 2 or 3 seconds.
Remove the plug and check if its electrode is wet. If the electrode is wet, fuel is
well supplied to your engine.
2.When the electrode is dry, check to find where the fuel is restricted.
(Check the fuel intake of the carburetor and fuel strainer intake.)
3. In case the engine does not start with well supplied fuel, try using fresh fuel.
WARNING
Wipe off spilled fuel carefully
before checking the spark plug.
Place spark plug as far away from
spark plug hole as possible.
Do not hold spark plug by hand
while checking.
Is there a strong spark across
the electrode?
1. Remove the spark plug and connect it
to the plug cap.
Turn key switch to START position
while grounding spark plug against
engine body.
2. Try with a new spark plug if the spark
is weak or there is no spark.
3. The ignition system is faulty if there is
no spark with a new spark plug.
Take your engine to your nearest
Robin dealer.

8. "HOW-TO" MAINTENANCE
INSPECTING THE SPARK
PLUG
■ Clean off carbon deposits on the
spark plug electrode using a plug
cleaner or wire brush.
■ Check electrode gap.
0.03 in
(0.7 to 0.8 mm)
Adjust gap to : 0.03 inches
(0.7mm to 0.8mm)
■ Use a proper spark plug :

OIL DRAIN PLUG
(ON BOTH SIDE)
OIL FILLER CAP
ENGINE OIL CHANGE
■ Initial oil change
・・・・・After 20 hours of operation
■ Thereafter
・・・・・Every 50 hours of operation
1. When changing oil, stop the engine
and loosen the drain plug.
2. Re-install the drain plug before refilling oil.
3. Refer to the recommended oil table
on page 5.
4. Always use the best grade and clean

■
Initial engine oil filter replacement should
be performed after 20 hours of operation.
Thereafter replace the engine oil filter
every 200 hours.
■
When installing a new oil filter, apply oil
to O-ring, attach the oil filter in position
and tighten 2/3 turns by hand or with
wrench after touching the O-ring to the
sealing surface of engine.
■
Run the engine for a minute ; stop the
engine and check for oil leakage around
the oil filter and recheck the oil level.
CLEANING AIR CLEANER
A dirty air cleaner element will cause starting
difficulty, power loss, engine malfunctions,
and shorten engine life extremely.
Always keep the air cleaner element clean.
Replaced the air cleaner element set more
often in dusty environments.
The air cleaner paper inner element and
urethane foam outer element can be
removed after removing knob and air
cleaner cover. When installing, set the
paper element and urethane foam on the
air cleaner base. Check that the grommet
is in position, and then install the cover
with knob tightened securely.
■
Urethane Foam cleaning
Wash and clean the urethane foam in
kerosene. Saturate in a mixture of 3
parts kerosene and 1 part engine oil, and
then squeeze to remove excess oil.
Clean or replace the urethane foam
element every 50 hours. (more often in
dusty environments)
■
Paper element
Clean by tapping gently to remove dirt
and blow off dust. Never use oil.
Clean or replace the paper element every
50 hours of operation, and replace element
set every 200 hours or once a year.
Clean and replace air cleaner elements
more often when operating in dusty
environments.
