It is of vital importance, before attempting to operate your engine, to read the general
'SAFETY INSTRUCTIONS AND WARNINGS' section on pages 2-4 of this booklet 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.
Keep these instructions in a safe place so that you may readily refer to them whenever necessary.
It is suggested that any instructions supplied with the aircraft, radio control equipment, etc., are accessible for checking at the same time.

SAFETY INSTRUCTIONS AND WARNINGS ABOUT YOUR O.S. ENGINE
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.
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
These cover events which might involve serious (in extreme circumstances, even fatal ) injury.
NOTES
These cover the many other possibilities, generally less obvious sources of danger, but which, under certain circumstances, may also cause damage or injury.
WARNINGS
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.
A weakened or loose propeller may disintegrate or be thrown off and, since propeller tip speeds with powerful engines may exceed 600 feet(180 metres) per second, it will be understood that such a failure could result in serious injury, (see 'NOTES' section relating to propeller safety).
Model engine fuel is poisonous. Do not allow it to come into contact with the eyes or mouth. Always store it in a clearly marked container and out of the reach of children.
Model engine fuel is also highly flammable. Keep it away from an open flame, excessive heat, sources of sparks, or anything else which might ignite it.
Do not smoke or allow anyone else to smoke, near to it.
Never operate your engine in an enclosed space. Model engines, like automobile engines, exhaust deadly carbonmonoxide. Run your engine only in an open area.
Model engines generate 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 result in a serious burn.

NOTES
This engine was designed for model aircraft. Do not attempt to use it for any other purpose.
Mount the engine in your model securely, following the manufacturers' recommendations, using appropriate screws and locknuts.
Be sure to use the silencer (muffler) supplied with the engine. 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.
Install a top-quality propeller of the diameter and pitch specified for the engine and aircraft. Locate 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 nut, using the correct size wrench.
Always check the tightness of the propeller nut and retighten it, if necessary, before restarting the engine, particularly in the case of four-stroke-cycle engines. If a safety locknut assembly is provided with your engine, always use it. This will prevent the propeller from flying off in the event of a "backfire", even if it loosens. Also, check the tightness of all the screws and nuts before restarting the engine.
If you install a spinner, make sure that it is a precision made product and that the slots for the propeller blades do not cut into the blade roots and weaken them.
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, unless you are highly experienced in tuning propellers for specialized competition work such as pylon-racing.
Use an electric starter for this engine. The wearing of safety glasses is also strongly recommended.

NOTES
Take care that the glow plug clip or battery leads do not come into contact with the propeller. Also check the linkage to the throttle arm. A disconnected linkage could also foul the propeller.
After starting the engine, carry out any needle-valve readjustments from a safe position behind the rotating propeller. Stop the engine before attempting to make other adjustments to the carburetor.
Adjust the throttle linkage so that the engine stops when the throttle stick and trim lever on the transmitter are fully retarded. Alternatively, the engine may be stopped by cutting off the fuel supply. Never try to stop the engine physically.
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.
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.
For their safety, keep all onlookers (especially small children) well back (at least 20 feet or 6 meters) when preparing your model for flight. 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.
Warning! Immediately after a glowplug-ignition engine has been run and is still warm, conditions sometimes exist whereby it is just possible for the engine to abruptly restart if the propeller is casually flipped over compression WITHOUT the glowplug battery being reconnected. Remember this if you wish to avoid the risk of a painfully rapped knuckle!

NOTES WHEN APPLYING
AN ELECTRIC STARTER
Do not over-prime. This could cause a hydraulic lock and damage the engine on application of the electric starter.
If over-primed, remove glowplug, close needle-valve and apply starter to pump out surplus fuel. Cover the head with a rag to prevent pumped out fuel from getting into your eyes.

ABOUT THE ENGINE
This is an overhead valve four stroke cycle engine for model aircraft use. This engine has a largest displacement of 32.4cc in the FS series and is suitable for big scale and sport models.
The new O.S. PD-08 diaphragm type fuel pump combined with the new 80R carburetor ensures constant fuel supply irrespective of aircraft attitude, position of fuel tank and fuel level, which results in steady running, better throttle response and easier adjustment. The new F-6010 silencer produces a milder four stroke sound.
NOTE
Do not relocate the carburetor controls, or the engine will not run properly.

FUEL TANK & LINES
Make sure that the tank is well rinsed out with methanol or glow fuel before installation and that the pickup weight is well clear of the bottom of the tank when held vertically.
The suggested fuel tank size is 500cc or 14 oz. This will give approximately 12-13 minutes running time when some part-throttle operation is included.
For plumbing, use heavy duty silicone tubing of 2.5mm inner dia and 5mm outer dia.
It is suggested to keep the distance between the carburetor and fuel tank within 500~600mm.
Vent
Approx. 15mm

INSTALLATION
Because the FS-200S-P is a powerful, large-displacement, single-cylinder four-stroke-cycle engine, it is essential to use very substantial engine mounting. Conventional wooden mounting beams should be of rigid hardwood and of at least 15mm or 5/8- in square section.
Make sure that the mounting beams are parallel and that their top surfaces are in the same plane.
