O.S. Engine FS-56A Owner's Instruction Manual - Warnings

2

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. 

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.

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

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.

Never operate your engine in an en-

closed space. Model engines, like auto-

mobile engines, exhaust deadly carbon-

monoxide. 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.

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 also highly 

flammable. Keep it away from 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.
