GRAUPNER HARPOON II Mode D'emploi page 59

Don't ignore our warnings or those provided by other manufacturers. They refer to things and processes
which, if ignored, can result in fatal injury or permanent damage.
You alone are responsible for the safe operation of your radio-controlled model and its jet engine.
Turbines may damage your hearing; always wear ear protectors when operating these engines.
•
Never run a jet engine in an enclosed space such as a workshop, garage, hall etc. Turbines develop very high
•
exhaust gas temperatures of +500°C and more, and therefore represent a serious fire hazard.
This model must only be operated outdoors.
•
Persons not required directly to operate the model and turbine must be kept well clear of the model. When
•
the jet engine is running, never look, reach or walk into the area of the hot exhaust gas flow.
When the turbine is running keep your hands at least 15 cm away from the area of the intake funnel. Keep
•
all extraneous objects - clothing, animals, children etc. - well clear. The engine develops a very powerful
suction force in this area, which is perfectly capable of sucking a hand, finger or other object into the
spinning compressor in an instant. Keep this potential hazard in mind at all times!
Before you run the engine, remove all loose objects from the area of the intake duct. This applies to cleaning
•
cloths, screws, nuts, cables and any other miscellaneous objects. Check in particular that you have not left
any small loose items in the inlet duct, such as waste materials from building the model, odd screws or even
sanding dust. Loose parts can very quickly enter the turbine and cause serious damage or personal injury.
When running the jet engine always ensure that no persons, animals or movable objects are in the plane of
•
rotation of the engine (hazard zone!).
Propellers and other rotating parts which are powered by a motor constitute a constant hazard and represent
•
a real risk of injury. Don't touch them with any part of your body. For example, a propeller spinning at high
speed can easily slice off a finger.
At low ambient temperatures the plug-in connections for the starting gas / fuel system may freeze or bind;
•
the starter mechanism may also tend to freeze up. Free the parts carefully - on no account use excessive
force.
All model flyers should behave in such a way that the danger to people, other creatures and property is
•
minimised. Never act in any way which will disturb other modellers and prevent safe, orderly flying at the
site.
Turbine fuel is toxic! Avoid skin contact at all times! Fuel must always be stored in clearly marked
•
containers, and kept out of the reach of children.
Jet-powered models are capable of extremely high airspeeds, and for this reason they must only be flown
•
where there is plenty of open airspace, and where unrestricted vision is guaranteed. Do not fly the model
when there is low cloud cover, and never fly directly into the sun in bright conditions. Since the model is so
fast, within a few seconds it can fly completely out of sight of the pilot. Always give way to full-size aircraft
of any kind well before there is the remotest chance of collision. To avoid all risks, stop the turbine and land
the model as quickly as possible. Manned aircraft and human life have top priority.
Do not fly the model unless you are in the best of health, and are able to concentrate fully on the activity.
