4.8. SPECIAL HAZARDS

You should be aware of the following special hazards and it is your duty to point them out to passengers and
spectators:

Propellers

Rotating, and indeed even stationary propellers pose potential dangers. Rotating propellers are very hard to
see,  so  special  attention  should  be  made  to  keep  persons,  and  especially  children  and  pets,  clear  of  the
aircraft  once it has been  started.  Persons should  never stand  either  in  line with the arc of the propeller  or
behind it since there is always a possibility that stones or other objects can be picked up and hurled at great
speed in any direction.  In the event of a propeller strike close down the engine immediately and do not re-
start  until  you  are  satisfied  that  no  structural  damage  has  been  done  to  the  propeller  or  airframe.    If  any
damage is visible, do not fly until the damaged blade has been repaired or replaced and the engine has been
inspected for shock load damage.

Running up and testing the engine on the ground, with or without the wing attached

Whenever  you  need  to  perform  an  engine  check  of  any  sort,  particular  care  must  be  taken  to  observe  the
following procedures:

1. Move  the  aircraft  to  an  area  clear  of  people,  animals  etc.    ALWAYS  LEAVE  AMPLE  ROOM  AHEAD  IN
CASE THE AIRCRAFT BREAKS FREE WHILE RUNNING UP.
2. Check the ground around the propeller area for loose stones etc. and remove any such objects.
3. Tie the aircraft to a solid object - a large and sound tree, a car with its parking brake applied, a concrete
post  etc  -  using  webbing  or  rope  which  is  sufficiently  strong  to  take  a  load  of  225  kilos  (500lbs)  minimum.
Securely attach both ends of the rope/webbing to the rear axles of the Quik and Quik GT450 just inboard of

THE EXHAUST SYSTEM: Do not touch the exhaust while the engine is running or directly after it has been
shut  down.    It  will  be  very  hot  and  will  inflict  serious  burns  if  touched.    Keep  items  of  clothing  and  the
aircraft's seat belts clear also.  Inspect the entire exhaust system for cracks and damage before and after
each flight.  Do not fly if there is any damage.

THE OIL SYSTEM: engine oil is stored in the reservoir underneath the left side of the engine. This
becomes very hot in use and will inflict serious burns if it comes into contact with human skin.

THE  RADIATOR  SYSTEM:  The  cooling  system  is  pressurised  when  the  engine  is  warm,  so  you  should
never open the cap until the engine has cooled down.  The coolant in the system is very hot and will inflict
serious burns if it comes into contact with human skin.

The coolant contains Ethylene Glycol which is harmful if swallowed.  Do not attempt to siphon or drain the
coolant system by sucking on a tube.

Failure to observe this Warning could result in injury or death.
