OPERATING YOUR MODEL SAFELY
Do not put your hands or
any objects into rotating
parts, as this could result in
serious accidents!
Handle fuel ONLY
outdoors!Vapors and
exhausts are very noxious to
health!
Right after use, do NOT
touch equipment on the
model such as the engine
and muffler, because they
generate high temperatures!
You may burn yourself
seriously touching them!
ONLY use glow fuel for radio
control models! Because the
use of gasoline and
kerosene in R/C models ac--
counts for fires, NEVER use
them!
NEITHER swallow fuel NOR
let it into your eyes!
Immediate measures should
be taken:
if fuel is swallowed, in-duce
vomit-ing. If fuel gets into
eyes, rinse them and consult
an orphamologist!
For accident prevention, do not run your model under
the following circumstances:
Always be considerate of other beach users whilst using this
model.
When rivers are swollen or their current is strong!
With weak radio batteries!
Also make sure that nobody is using the same
frequency as you do at the same time!
When the boat behaves or operates strangely!
With R/C boats, discover a new world of pleasure.
Wheth-er you run your boat on lakes, rivers or else-
where, take precautionary measures to avoid accidents.
In order to avoid accidents and personal injury, be sure to observe the following:
15
Fuel is highly inflammable and high-explosive!
PROHIBITED
PROHIBITED
NEVER use fuel indoors or in places with open fires and
sources of heat!
Store fuel ONLY in cool, dry and dark places out of
childrenÕs reach! Tightly shut the cap!
Do NOT dispose of empty fuel
cans into a fire! There is danger
of explosion!
In the sea or in other salt water.
