GRAUPNER Wave Explorer TX 2 PY Betriebsanleitung Seite 13

Do not carry out any work on the power system unless the motor is disconnected from the drive battery.
•
When the drive battery is connected, keep well clear of the area around the propeller, as this
•
represents the greatest risk of accident and injury. Make sure any spectators do the same.
Do not exceed the recommended voltage of the drive battery. Increasing the voltage may cause the
•
motor and / or the mechanical motor switch to overheat, and the electrical leads can even melt. In the
worst case this may cause the model to go up in flames and be completely ruined.
The maximum continuous load capacity of the mechanical motor switch is only fifteen Amps.
•
Check that all the drive train components work smoothly and freely. This applies in particular when you
•
are running the model, as leaves and other detritus can get caught up in the power train. If this happens
and you do not remove the obstruction, the motor, the motor switch or the rudder servo may be ruined
due to overloading.
The battery must never be left on charge unsupervised. Observe the instructions included with the
•
battery charger and the battery at all times.
If you are using a battery charger powered by a car battery, always carry out the charging process
•
outside the car.
Ensure that the servos are not mechanically obstructed at any point in their travel.
•
Dry cells and rechargeable batteries must never be short-circuited. Do not allow them to come into
•
direct contact with water.
Allow the motor and the motor switch to cool down after every run. Don't touch the hot parts!
•
Do not subject the model to high levels of humidity, heat, cold, vibration or dirt.
•
Remove all batteries from the model and the transmitter prior to transporting and storing them, and
•
always store them in such a way that there is no chance of short-circuiting the contacts.
The drive battery should always be removed from the boat prior to transporting it.
•
Secure the model, the batteries and the RC equipment carefully when transporting them. They may be
•
seriously damaged if they are free to slide about.
Please bear in mind that the boat only has one forward speed (model stopped / full-throttle), i.e. the
•
motor will immediately burst into life at full speed when you activate the motor switch. This means that
the model will start running very abruptly, and it has no "reverse gear". Keep this in mind at all times
when you are operating the boat.
Always ensure that the tin-contact connectors between the RC box and the drive motor are properly
•
insulated; they must never make direct contact with each other.
Towards the end of each run you will notice that the model is slowing down; this is your warning of an
•
almost flat battery. Drive the boat straight back to the bank at this point, and cease operations. You
must now recharge the battery before running the boat again.
If you wish to operate the model on moving water (e.g. a river), bear in mind that it could be washed
•
away downstream if the battery fails or a malfunction occurs.
If you have to salvage the model, take care not to risk your own life or that of others.
•
Check regularly that the hull is completely watertight, as the model may sink if too much water enters
•
the hull. Check the boat for damage before every run, and ensure that water cannot penetrate the hull
through the propeller shaft or rudder openings. Check the rubber seals on the boat in particular. The RC
box should always be kept closed, so that spray cannot enter it from above. Components damaged by
water will not be repaired under guarantee!
Secure the hatch cover by pushing the split pin through the hole in the retainer, working from the rear of
•
the cover.
Care and maintenance
Clean the model carefully after every run, and use a piece of kitchen paper or similar to remove any
•
water which penetrates the hull. Leave the hatch cover off the boat for a long period after every run, so
that any residual damp can evaporate.
Clean the model and transmitter using suitable cleaning materials. If you are not sure about this, ask
•
your model shop for advice
Lubricate the propeller shaft at regular intervals. Water-neutral lubricants are readily available; please
•
ask your local model shop for details.
If you know that the boat will not be run for a long period, dismantle all the moving parts (propeller shaft
•
etc.), then clean and re-lubricate them. Remove all dry and rechargeable batteries from the model and
the transmitter, and store them separately.
