It is of vital importance, before attempting to operate your

engine, to read the general 'SAFETY INSTRUCTIONS

AND WARNINGS' in the following section and to strictly

adhere to the advice contained therein.

Also, please study the entire contents of this

instruction manual, so as to familiarize yourself with

the controls and other features of the engine.

SAFETY INSTRUCTIONS AND WARNINGS ABOUT YOUR O.S. ENGINE

The advice which follows is grouped under two

headings according to the degree of damage or

danger which might arise through misuse or

neglect.

WARNINGS

NOTES

These cover events which might involve serious

(in extreme circumstances, even fatal) injury.

These cover the many other possibilities, generally

less obvious sources of danger, but which, under

certain circumstances, may also cause damage or

injury.

WARNINGS

ABOUT THE ENGINE

STANDARD ACCESSORIES

ENGINE PARTS NAME

INSTALLATION

Remember that your engine is not a " toy ", but a

highly efficient internal-combustion machine

whose power is capable of harming you, or others,

if it is misused or abused. As owner, you, alone,

are responsible for the safe operation of your

engine, so act with discretion and care at all times.

If at some future date, your O.S. engine is acquired

by another person, we would respectfully request

that these instructions are also passed on to its

new owner.

If you have to carry the model to the take-off point

with the engine running, be especially cautious.

Keep the propeller pointed away from you and walk

well clear of spectators.

Switch off the ignition module to stop the engine or

fully close the throttle valve via the transmitter to

shut off the fuel supply. Otherwise there is a

possibility of injury.

Immediately after the engine is stopped, the engine

may start with a crank even when the igniter switch

is off. Do not crank the engine, or there is a

possibility of injury.

Be sure to install an externally operable switch for

the ignition system battery to stop the engine if it is

started unintentionally with the radio transmitter

turned off or there is the possibility of injury.

Connect the throttle linkage so that the engine can

be stopped via radio operation.

Always check the throttle linkage.If it is disconnected,

throttle action becomes uncontrollable, which may

result in a serious accident.

Take care that loose clothing (ties, shirt sleeves,

scarves, etc.) do not come into contact with the

propeller. Do not carry loose objects (such as

pencils, screwdrivers, etc.) in a shirt pocket from

where they could fall through the propeller arc.

Use an electric starter for this engine. The wearing of

safety glasses is also strongly recommended.

If you try hand starting, be sure to use a chicken stick

or heavy glove. Never attempt to start the engine

with a bare hand.

Be sure to carry out adjustments of the high speed

needle and slow speed needle after stopping the

engine.

Do not start your engine in an area containing loose

gravel or sand. The propeller may throw such

material in your face and eyes and cause injury.

Discard any propeller which has become split,

cracked, nicked or otherwise rendered unsafe.

Never attempt to repair such a propeller: destroy it.

Do not modify a propeller in any way.

Install the propeller on the shaft so that the curved

face of the blades faces forward – i.e. in the direction

of flight. Firmly tighten the propeller washer and

propeller installing screws using the correct size

wrench. Always check the tightness of propeller

installing screws and retighten them, if necessary,

before starting the engine. Also, check the tightness

of all the screws and nuts before restarting the

engine.

When checking a spark plug with the power source

on, do not hold the plug, plug cap, high tension cord ,

or you will get a shock.

Install a top-quality propeller of the diameter and

pitch specified for the engine and aircraft.

Any propeller requires utmost attention to handle.

Be sure to follow the instruction manual supplied with

a propeller.

This engine was designed for model aircraft.

Do not attempt to use it for any other purpose.

Start the engine only after installing it in the model.

Do not start the engine before installing it in the

model, or there is a possibility of injury.

Be sure to use an effective silencer (muffler).

Frequent exposure to an open exhaust may

eventually impair your hearing. Such noise is also

likely to cause annoyance to others over a wide area.

Mount the engine in your model securely, following

the manufacturers’ recommendations.

For their safety, keep all onlookers (especially small

children) well back (at least 10 meters) when

preparing your model for flight.

NOTES

Model engines generates considerable

heat. Do not touch any part of your engine

until it has cooled. Contact with the muffler

(silencer), cylinder head or exhaust header

pipe, in particular, may results in a serious

burn.

Observe the laws and regulations in each

country and district concerning the usage,

transportation and storage of gasoline. Ask

details at fire station in each district.

Never operate your engine in an enclosed space.

Model engines, like automobile engines, exhaust

deadly carbon-monoxide. Run your engine only

in an open area.

Do not operate the engine nor model alone, or

there is a possibility of injury.

Carry out the mixing of the gasoline and

oil outdoors or in a well ventilated place

away from any source of fire to prevent the

possibility of a fire.

Refill the fuel tank only after the engine is

well cooled down, or there is a danger of

fire.

Never touch, or allow any object to come

into contact with the rotating propeller and

do not crouch over the engine when it is

running.

Gasoline is poisonous. Do not allow it

come into contact with the eyes or mouth.

Always store it in a clearly marked

container in a cool and dark place and out

of the reach of children. There is a

possibility that it may damage your health.

Gasoline is highly flammable. Keep it away

from an open flame, excessive heat,

sources of sparks, or anything else which

might cause it to ignite. Do not smoke or

allow anyone else to smoke near to it.

This engine is designed for experienced fliers.

Beginners and newcomers should not use this engine.

The engine unit, silencer and carburetor are

specially designed.

The normal rotation direction of the engine is

counterclockwise facing to the propeller.

It offers broad power characteristics suitable for

sport flight as well as acro flight.

The specially designed ignition module “IG-02” is

equipped with a micro computer and designed not to

operate below 120 rpm.

The new E-6020 silencer develops very efficient silencing.

The engine can be easily choked for starting by

connecting a choke rod (not supplied) to the

carburetor choke lever.

Use a tank designed for gasoline. (Tanks designed

for glow fuel use a rubber cap which is deteriorated

by gasoline.)

A 600cc tank will provide 12~13 minutes flight.

(With full throttle, it will provide 7~8 minutes flight.)

Install a commercially available gasoline fuel filter

between fuel tank and carburetor. (Clean the filter

from time to time.)

For plumbing use TYGON F-4040 (Yellow color) or

strong nitrile rubber of more than 3mm ID and 6mm

OD. Replace tubing periodically as it becomes

hardened. (Replace tubing inside the fuel tank every

six months.)

FUEL TANK & LINES

Use a strong enough material for the mounting face

of the model, such as birch ply firewall of more than

8mm thick.

Make sure the mounting face of the model is flat. If it is

uneven, work on it to be flat. (When shims are added

to change the thrust angle, work on it to be flat.)

Engine mounting face has been high-precision

machined flat. Make sure mounting face of the

model is also flat.

Use 5mm steel hex socket head bolts to install the

engine. (Do not use brass, soft steel nor aluminum

screws, because they are not strong enough.) Also,

use the Nord Lock Washers (optional extra) and

other anti-loosening washers or apply locking agent.

Be sure that there is sufficient air intake and outlet

area on the model for engine cooling to avoid

overheating. (Pay careful attention to the cooling

since a gasoline engine generates more heat than a

glow engine.)

Secure at least a 30mm dia. area around the air

intake of the carburetor so that the air intake will not

be restricted. (Cut out the firewall big enough if

necessary.)

Use fuel line keepers of stainless wire, etc. at the

end of the tubing to prevent at from coming off.

This engine does not require a muffler pressurized

fuel system but be sure to provide an air vent.

#38608 GT60 w/o muffler does not include the above

muffler set.
