Care And Maintenance - GRAUPNER S-204 Operating Instructions Manual

The following points are important and must be observed at all times:
•
This model is not suitable for young persons under 14 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.
•
Operate the model carefully when there are persons or animals in the water, and always keep a safe
distance away from people and animals.
•
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
connections are secure.
•
The 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 50 m
away from the model carrying the transmitter. Your friend will be able to tell you whether all the
working functions operate correctly at this range.
•
Ensure that the frequency you intend to use 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 disconnected and removed the battery.
•
When the drive battery is connected keep well clear of the area around the propellers. Make sure any
spectators do the same.
•
Do not be tempted to exceed the recommended operating voltage. Higher voltages may cause the
motors 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 in particular when the
boat is running, as leaves and other debris may get caught in the power system components. The
motors 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 its low speed may result in the model drifting
off downstream.
•
If you have to salvage the model, 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.
•
Allow the boat to dry out thoroughly after each session on the water.

Care and maintenance

•
Clean the model carefully after every run, and remove any water which penetrates the hull. If water
gets into the RC components, dry them out carefully and send them to your nearest GRAUPNER
Service Centre for checking.
•
Clean the model and transmitter using suitable cleaning agents only. All you need is a lint-free cloth.
Never use chemical cleaners, solvents, methylated spirits, white spirit or similar.
•
Lubricate the propeller shafts at regular intervals by applying a small drop of oil to the bearings. Use a
type of oil which does not soil or contaminate water, e.g. Order No. 206. At the end of the season we
recommend that you remove the propeller shaft and re-lubricate it using water-neutral grease, Order
No. 570.
