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 somefuture 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
Never touch, or allow any object to come into contact with, the rotating propeller and donot 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 intocontact 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 automobileengines, exhaust deadly carbonmonoxide. Run your engine only in an open area.

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.

Model engines generate considerable heat. Do nottouch 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.

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. Besure 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. If you remove the glowplug from the engine and check its condition by connecting the battery leads to it, do not hold the plug with bare fingers.Use an appropriate tool or a folded piece of...
