9. WARNING NOTES
No toy. Not suitable for children under 14 years.
Keep the product out of the reach of children.
Pay close attention to the following points, as they can de-
stroy the product and void your warranty. Non-observance
of these points can lead to property damage, personal and
severe injuries!
• Never leave the product unsupervised while it is switched on,
in use or connected with a power source. If a defect occurs,
it could set fire to the product or the surroundings.
• Never wrap your product in plastic film, metal foil or similar.
In fact, make sure it gets enough fresh air.
• Avoid incorrect connections or connections with reversed
polarity of the product.
• All wires and connections have to be well insulated. Short-
circuits can possibly destroy the product.
• Never allow this product or other electronic components to
come in contact with water, oil or fuels or other electrocon-
ductive liquids, as these could contain minerals, which are
harmful for electronic circuits. If this happens, stop the use
of your product immediately and let it dry carefully.
• Never cut off or modify the original plugs and original wires.
• Never open the product and never solder on the PCB or other
components.
• Never use this product when the case is open, damaged or
missing or when the product is wrapped in a shrink-fit tube.
This will reduce protection, may cause short circuits and da-
mage the product.
• Always remove the battery from your product or disconnect

the product from the power source, if the product is not in use.
Always remove the battery from your product or disconnect
Always remove the battery from your product or disconnect
• Always switch on your transmitter first before you switch on the receiver or the speed control. The
receiver could receive interference signals, start full acceleration and damage your model. When you
switch off, make sure you do so in the reverse sequence. First switch off the receiver and speed control,
then switch off the transmitter.
• Never solder a Schottky diode to the motor when you are using this speed-control.
• If the speed-control is connected to the motor, never run the motor directly with a separate battery or
run-in device.
• Never change the polarity of the receiver connector.
• Always wire up all the parts of the equipment carefully. If any of the connections come loose as a result
of vibration, you could loose control over your model.
• Avoid soldering longer then 5 seconds per soldering joint when replacing the power wires to prevent pos-
sible damage to the product due to overheating of the components. Use a high power soldering station
for soldering.
• Never apply full throttle if the motor is not installed. Due to the extremely high RPMs without load, the
motor can get damaged.
