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.
