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.

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.

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

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  meters)  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 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  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.

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.

Fit 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. A safety locknut assembly is provided.  Always use it. This will prevent the propeller 
from flying off in the event of a "backfire", even if it loosens.

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 carburettor.

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!
