federal agencies as causing cancer or reproductive toxicity. When
checking or changing engine oil, take care not to ingest, breathe
the fumes, or contact used oil.
• Do not work on this equipment when mentally or physically
fatigued, or after consuming any alcohol or drug that makes
the operation of equipment unsafe.
EXHAUST SYSTEM
• Exhaust products of any internal combustion engine are toxic and
can cause injury, or death it inhaled. When operating the engine in a
confined area, make sure the ventilation system is operating
properly.
• DO NOT use exhaust gases to heat a compartment.
• Make sure that your exhaust system is free of leaks. Make sure that
exhaust manifolds are secure and are not warped by bolts unevenly
torqued.
BATTERIES
• Before starting work on the engine, disconnect batteries to prevent
inadvertent starting of the engine. Disconnect negative (-) cable first. EXHAUST GAS IS DEADLY!
• DO NOT SMOKE while servicing batteries. Lead acid batteries give
off a highly explosive hydrogen gas which can be ignited by flame,
electrical arcing or by smoking.
• Verify battery polarity before connecting battery cables. Connect
negative (-) cable last.
Exhaust gases contain carbon monoxide, a poisonous gas that can
cause unconsciousness and death. It is an odorless and colorless gas
formed during combustion of hydrocarbon fuels. Symptoms of carbon
monoxide poisoning are:
•Dizziness

LOCATING
If the tank is mounted above the carburetor, a fuel shut-off valve must
be connected between the fuel tank and the fuel pump.
Locate the engine at least 1 meter (3.0 ft) away from buildings or other
structures. Provide proper exhaust routing. Refer to EXHAUST SYS-
TEM below. Do not use the engine near flammables or other hazard-
ous materials such as trash, rags, lubricants, or explosives.
When determining the mounting location, make sure of the following:
• Gas and oil can easily be checked and supplied
• Oil can be changed.
Note: To prevent fuel from flooding the carburetor, the fuel valve
must be closed when the engine is not running.
Properly install fuel lines to the carburetor bycompletely inserting the
hose onto the fitting and then secure it with a hose clamp.
Gaseous fuels are flammable and explosive and
! WARNING
• The air cleaner can be serviced
can cause severe personal injury or death.
Do not smoke if you smell gas or are near fuel
tanks or fuel-buring equipment or are in an area
sharing ventilation with such equipment. Keep
flames, sparks, pilot lights, electrical switches,
arc-producing equipment and all other sources
of ignition well away. Keep a type ABC fire
extinguisher handy.
• Spark plugs can be checked.
Carefully examine the engines position, the method of connecting it to
a machine, and the foundation and support structure.
Locate the engine in a safe area on a stable level surface free of small
rock, loose gravel, etc.
! CAUTION
Operating the engine on an incline may cause
seizure due to improper lubrication; even at
maximum oil level.
Do not refill the fuel tank while the engine is running. Do not overfill the
tank.
Wipe away any spilled fuel and wait until it has dried before starting
the engine.
EXHAUST SYSTEM
EXHAUST GAS IS DEADLY! Engine-powered equipment must never
be operated inside buildings or other enclosed spaces.
If a long exhaust pipe is used, the internal resistance results in loss
of engine power. The exhaust pipe ID must increase in proportion to
exhaust pipe length. For example, if the exhaust pipe is:
Fuel recommendations
Use clean, fresh unleaded gasoline having a minimum octane rat-
ing (Anti-Knock Index) of 87. This engine is certified to operate on
unleaded gasoline.
less than 3.0 m (9.8 ft.) long - pipe ID = 30mm (1-3/16in)
less than 5.0 m (16.4 ft)long - pipe ID = 33mm (1.3in)
During some periods of the year only mandated “oxygenated” gaso-
lines may be available. These are acceptable for use, but not prefer-
able. Do not use gasoline or gasoline additives (de-icers) containing
methanol because methanol can be corrosive to fuel system compo-
nents.
It is the responsibility of the equipment operator(s) to check for
exhaust leaks on a daily basis and to have all leaks repaired before
continuing to operate the equipment.

Installation
Check the oil level daily, before starting. Keep the oil level between the
upper and lower level on the gauge.
ENGINE OIL
Recommendations
Use premium quality motor oil, Class SE or higher. Look for the SAE
(Society of Automotive Engineers) or API viscosity grade. Referring to
the table below, choose the viscosity grade appropriate for the ambient
temperatures expected during the period of time until the next sched-
uled oil change.

STARTING BATTERIES
An engine equipped with an electric starter requires a properly sized
battery along with appropriately sized interconnecting cables to insure
proper starting. Neither cranking performance or starter service life will
be satisfactory if an undersized battery is used.
Single-grade SAE 30 oil is preferable when temperatures are 50° and
90°F (10° - 32°C).
If multi-grade oil is used, oil consumption tends to increase if the ambi-
ent temperature is high.
Use a battery rated 12V-30 amp or larger.
The customer must supply battery cables. Use the table below to
select the proper cable for the positive side connection.
Connect a ground strap to the negative terminal. Use a flat strap
25.0mm (0.25”) wide.
Filling and Change Interval
After the first 20 hours of operation the initial oil and oil filter should be
replaced.
Thereafter, change the oil every 100 hours of operation and change
the oil filter every 200 hours.
Apply a thin coat of oil to the oil filter gasket surface and install by
tightening the oil filter about 3/4 turn after the seal has reached the
crankcase surface.
The oil capacity of the crankcase is 1.55L (53 fl.oz.).
When filling the crankcase, keep the engine level and fill up to the up-
per mark of the oil gauge. Check the oil with the oil gauge pushed all
the way in its seat.

place.
RETURNING THE ENGINE TO SERVICE
OUT-OF-SERVICE PROTECTION
1 Remove the cover and all protective wrapping and the plug from the
exhaust outlet.
Protect an engine that will be out of service for more than 30 days as
follows:
2 Check the tag on the oil base. Change the oil if the viscosity is not
appropriate for the expected ambient temperatures.
1 Run the engine until it reaches normal operating temperature then,
shut-off the fuel supply and let the engine run until it stops.
3 Check the fuel filter and fuel lines to make sure they are secure and
2 If the equipment will not be operated for more than 30days, add a
fuel preservative (ie. Sta-Bil) to the equipment fuel tank. Follow the
instructions on the container label. Unless a preservative is added,
gasoline will deteriorate causing fuel system corrosion, gum
formation and varnish-like deposits which can lead to hard starting
and rough operation.
have no cracks.
4 Check that the choke, throttle and governor linkages move freely.
5 If so equipped, clean and check the battery according to the battery
or equipment manufacturer’s instructions and connect the battery
cables (positive (+) cable first).
3 Drain oil from the engine while it is still warm. Refill with fresh oil
and attach a tag stating the viscosity of the oil used.
6 Start the engine. The initial startup may be slow and there may be
smoke and rough operation for a few minutes until the oil in
the cylinder burns off. If the engine does not start, clean or replace
the spark plug as it may have been fouled by the oil added to the
cylinder when the equipment was stored.
4 To prevent rust in the cylinder bore, remove the spark plug and pour
30mL (2 tbsp. or 1oz.) of SAE 30 oil in the opening. Turn the

10 DO NOT FILL TO A LEVEL ABOVE THE FULL MARK ON THE
DIPSTICK. Drain the excess oil if too much has been added.
Foam Filter
Remove and wash the urethane foam in water and detergent.
Squeeze the foam wrapper dry like a sponge. Rinse with clean water
and allow it to dry. Coat the wrapper evenly with 14 mL (one tbsp.) of
SAE 30 engine oil. Knead the oil into the wrapper and squeeze out the
excess oil.
Note: Failure to adequately wring out excess oil from the wrapper
may cause a drop in engine power due to restriction of inlet air.
Install the foam wrapper over the paper air cleaner element by stretch-
ing it over the inner cover. Completely cover all exposed paper pleats.
Replace the air cleaner assembly when it becomes torn or stretched.
Air Cleaner Element Replacement
To keep anything from entering the carburetor and engine while the
air cleaner element is off, pull the choke knob to the full-choke posi-
tion to close the choke plate in the carburetor. Remove the outer cover
and wipe away loose dust and debris from the air cleaner assembly.
Remove the air cleaner assembly. Wipe off dust and debris from the air
cleaner base. Use forced air to blow off dust and debris from the paper
element.
! CAUTION
Too much oil can cause high oil consumption, high
operating temperatures and oil foaming. Too little oil
can cause severe engine damage. Keep the oil level
between the Full and Add marks on the dipstick.
Reinstall the paper element on the engine. Replace the foam wrapper
and outer cover. Secure with the wing nut.
11 Reconnect the spark plug wires and battery.
12 Start the engine and run it for a short time while checking for oil
leaks around the drain plug and oil filter. Do not overtighten: tighten
only as necessary to eliminate leaks.

SPARK PLUG MAINTENANCE AND REPLACEMENT
To adjust the speed control solenoid:
1 Run the engine with no load until the engine control times out
(about 15 seconds) and energizes the solenoid.
Refer to the Specifications for spark plug type and gap specifications.
Check and clean spark plugs every 200 hours. Replace plugs every
500 hours.
2 Adjust engine to 2200 RPM by loosening the two slotted screws
retaining the solenoid.
To prevent cross threading the spark plug, always thread it in by hand
until it seats. If the spark plug is being reused, turn it with a wrench
and additional 1/4 turn. If the spark plug is new, turn it an additional 3/8
to 1/2 turn. If you have a torque wrench, tighten a new spark plug to
11.8-14.7 N-m (120-150 Kg/cm) (8.7-10.9 ft/lb).
3 Slide solenoid forward to increase the speed, or backwards to
decrease the speed.
4 Retighten the two screws.
CHECKING BATTERIES
Following reassembly of either the carburetor or intake manifold, re-
align the governor arm on the governor shaft BEFORE making speed
adjustments to compensate for the slightly different alignment of parts.
Every 50 hours or once a month check the fluid level of the battery.
Refill with distilled water if levels are low.
Governor and Speed Control Assembly
Battery gas is explosive. Wear safety glasses and do
not smoke while servicing batteries. Lead acid
batteries give off a highly explosive hydrogen gas
which can be ignited by flame, electrical arcing or
smoking.

High Altitude Engine Operation
How to remove the spark arrestor
•
•
•
Please have an authorized Robin America service dealer modify
this engine if it is to be run continuously above 5,000 feet (1,500
meters). Failure to do so, may result in poor engine performance,
spark plug fouling, hard starting, and increased emissions.
1. Remove the flange bolts from the muffler cover and remove the
muffler cover.
2. Remove the special screw from the spark arrestor and remove the
spark arrestor from the muffler.
Carburetor modification by an authorized Robin America service
dealer will improve performance and allow that this engine meets
EPA (Environmental Protection Agency) and California ARB (Air
Resources Board) emission standards throughout its useful life.
Clean the spark arrestor screen
Use a brush to remove carbon deposits from the spark arrestor
screen. Be careful to avoid damaging the screen.
An engine converted for high altitudes can not be run at 5,000 feet
or lower. In doing so, the engine will overheat and cause serious
engine damage. Please have an authorized Robin America service
dealer restore high altitude modified engines to the original factory
specification before operating below 5,000 feet.
The spark arrestor must be free of breaks and holes. Replace the
spark arrestor if it is damaged.
Install the spark arrestor, and muffler protector in the reverse order of
disassembly.
Spark Arrestor (Optional)
In a dry or wooded area, it is recommendable to use the engine with a
spark arrestor. Some areas require the use of a spark arrestor. Please
check your local laws and regulations before operating your engine.
The spark arrestor must be cleaned regularly to keep it functioning as
designed.
Spark Arrestor Screen
A clogged spark arrestor:
•
•
•
•
Prevents the flow of exhaust gas
Reduces engine output
Increases fuel consumption
Makes starting difficult
If the engine has been running, the muffler and the spark arrestor will
be very hot. Allow the muffler to cool before cleaning the spark arres-
tor.
