• 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

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 bycompletely 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.

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 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.

EXHAUST GAS IS DEADLY!  
! WARNING  
Never operate engine-powered equipment  
indoors without a proper exhaust system, ample fresh  
air ventilation and an operable carbon monoxide  
detector.  
7 Plug the exhaust outlet to prevent moisture, dirt, bugs, ect. from  
entering.  
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 ame, electrical arcing or  
smoking.  
! WARNING  
2. Use fresh gasoline and ll the fuel tank after each day’s use to  
reduce problems with moisture condensation if this is a gasoline  
engine.  
3. Keep the battery in a well-charged condition.  
8 Disconnect the battery (negative (-) cable rst) and follow the  
battery or equipment manufacturer’s storage instructions.  
4. After each use push the equipment throttle knob or lever to the  
middle of its speed range. Then, if ice forms on the linkage during  
storage it will be easier to start the engine.  
9 Cover the engine with a plastic sheet or canvas and store in a dry  
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 lter 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 rst).  
3 Drain oil from the engine while it is still warm. Rell 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  
crankshaft several times by hand and reinstall the spark plug.  
5 Clean the outside of the engine with an oiled cloth.

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 lter. 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 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  
batteries give off a highly explosive hydrogen gas  
which can be ignited by ame, 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 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.

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.
