GRAUPNER BERNHARD GRUBEN Instructions De Montage page 45

The following points are important and must be observed at all times:
•
This model is not suitable for young persons under fourteen years of age.
•
The projecting parts of the model may be sharp, and the aerials and masts could cause eye injuries.
•
Bear in mind that tools can be dangerous; always be careful when handling them.
•
Never operate the model when there are persons or animals in the water, as its relatively high speed
constitutes a considerable injury hazard.
•
Never run your model in protected sites, animal or plant sanctuaries or sites of special scientific interest
(SSSIs). Check with your local authority that the stretch of water you wish to use is suitable for model
boats.
•
Never run the boat in salt water.
•
Never run the boat in adverse conditions, e.g. rain, storm, strong wind, choppy water or strong currents.
•
Read the instructions provided with your radio control system and accessories, and observe the
recommendations.
•
Before you run the model check that the radio control system is working reliably, and that all con-
nections are secure.
•
Dry batteries must never be recharged. Only batteries marked as "rechargeable" are safe to recharge.
•
Check the range of the radio control system before each session: ask a friend to walk about 100 m
away from the model carrying the transmitter. Your assistant will be able to tell you whether all the
working functions operate correctly at this range.
•
Ensure that the frequency on which you intend to transmit is not already in use by other modellers.
Never run your boat if you are not certain that your channel is free.
•
Bear in mind that other radio equipment and transmitting stations can cause serious interference to the
model. Ensure that no equipment of this type is being used in the vicinity while you are operating the
model.
•
Do not carry out any work on the drive train unless you have already disconnected the battery.
•
When the drive batteries are connected, keep well clear of the area around the rotating parts - the
propellers in particular - and make sure any spectators do the same.
•
Do not be tempted to exceed the recommended operating voltage. Higher voltages may cause the
motor or speed controller to overheat, and the electrical cables may even melt. If this should happen,
the model could easily be ruined.
•
Check that all the drive train components work smoothly and freely. This applies especially when the
boat is running, as leaves and other debris may get caught in the power system components. The motor
and speed controller could then be ruined by overloading.
•
Dry cells and rechargeable batteries must never be short-circuited. Do not allow them to come into
direct contact with water.
•
Remove the rechargeable battery and the dry cells in the transmitter and receiver pack if the model is to
be transported, or will not be used for a long period.
•
Do not subject the model boat to high levels of humidity, heat, cold or dirt.
•
Secure the model and your RC equipment carefully when transporting them. They may be seriously
damaged if they are free to slide about.
•
Never operate the boat in moving water (e.g. a river), as any fault which develops could result in the
model drifting off downstream.
•
If you have to salvage the boat, take care not to risk your own life or that of others.
•
Take particular care to ensure that the boat is completely watertight, as it will sink if too much water
enters the hull. Check the model for damage before every run, and ensure that water cannot penetrate
through the shaft bearings or the rudder bush.
•
Allow the boat to dry out thoroughly after each session.
•
Be sure to check repeatedly during the first run that the shaft systems are watertight. If water enters the
hull through the shaft tubes, remove the shafts and lubricate the tubes with plenty of grease, Order No.
570.
•
NOTE: the electric motors installed in the model must not be discarded in the household rubbish. When
it is worn out, it should be removed from the boat and taken to your local collection point for electrical
waste.
•
NOTE: if you are using drive batteries wired in parallel, please remember that they should only be
connected while the boat is running. If the batteries are inter-connected under no-load conditions, they
may interact with each other and suffer damage. For this reason you should connect the batteries just
before running the boat, and disconnect them again immediately after the run. Never store the batteries
with the parallel cables connected.
