moving parts, etc.  
• Used engine oils have been identied by some state and  
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  
conned 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 rst. 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 ame,  
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  
• Vomiting  
PROTECT AGAINST MOVING PARTS  
Headache  
• Do not wear loose clothing in the vicinity of moving parts, such as  
PTO shafts, ywheels, blowers, couplings, fans, belts, etc.  
• Keep your hands away from moving parts

Throbbing in Temples  
Weakness and Sleepiness  
If you experience any of these symptoms, get out into fresh air imme-  
diately, shut down the unit and do not use it until it has been inspected.  
The best protection against carbon monoxide inhalation is proper  
installation and regular, frequent inspections of the complete exhaust  
system. If you notice a change in the sound or appearance of exhaust  
system, shut the unit down immediately and have it inspected and  
FUEL SYSTEMS  
• DO NOT ll fuel tank while engine is running  
• DO NOT smoke or use an open ame in the vicinity of the engine or  
fuel tank. Internal combustion engine fuels are highly ammable.  
• Fuel line must be made of steel tubing which adequately secured,  
and free from leaks. Tubing which connects to the carburetor should repaired at once by a competent mechanic.  
be factory approved exible line. Do not use copper tubing as the  
exible lines as copper will harden and become brittle enough to  
break.  
KEEP THE UNIT AND SURROUNDING AREA CLEAN  
• Make sure that oily rags are not left on or near the engine.  
• Remove all unnecessary grease and oil from the unit. Accumulated  
grease and oil can cause overheating and subsequent engine  
damage and present a potential re hazard.  
• Be sure all fuel supplies have a positive shutoff valve.  
• Benzene and lead, found in some gasoline, have been identied by  
some state and federal agencies as causing cancer or reproductive  
toxicity. When checking, draining, or adding gasoline take care not

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 ammables 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 ooding the carburetor, the fuel valve  
must be closed when the engine is not running.  
Properly install fuel lines to the carburetor by completely inserting the  
hose onto the tting and then secure it with a hose clamp.  
Gaseous fuels are ammable 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  
ames, sparks, pilot lights, electrical switches,  
arc-producing equipment and all other sources  
of ignition well away. Keep a type ABC re  
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 rell the fuel tank while the engine is running. Do not overll 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 certied 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.

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 SJ or SL. 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 at strap  
25.0mm (0.25”) wide.  
Filling and Change Interval  
After the rst 20 hours of operation the initial oil and oil lter should be  
replaced.  
Thereafter, change the oil every 100 hours of operation and change  
the oil lter every 200 hours.  
Apply a thin coat of oil to the oil lter gasket surface and install by  
tightening the oil lter about 3/4 turn after the seal has reached the  
crankcase surface.  
The oil capacity of the crankcase is 1.55L (53 .oz.).  
When lling the crankcase, keep the engine level and ll up to the up-  
per mark of the oil gauge. Check the oil with the oil gauge pushed all  
the way in its seat.

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 Specications for spark plug type and gap specications.  
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 uid level of the battery.  
Rell 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

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 ange bolts from the mufer cover and remove the  
mufer cover.  
2. Remove the special screw from the spark arrestor and remove the  
spark arrestor from the mufer.  
Carburetor modication 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 modied engines to the original factory  
specication 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 mufer 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 ow of exhaust gas  
Reduces engine output  
Increases fuel consumption  
Makes starting difcult  
If the engine has been running, the mufer and the spark arrestor will  
be very hot. Allow the mufer to cool before cleaning the spark arres-  
tor.
