SAFETY PRECAUTIONS

All of us at Traxxas want you to safely enjoy your new model. 
Operate your model sensibly and with care, and it will be exciting, 
safe, and fun for you and those around you. Failure to operate your 
model in a safe and responsible manner may result in property 
damage and serious injury. The precautions outlined in this manual 
should be strictly followed to help ensure safe operation. You alone 
must see that the instructions are followed and the precautions are 
adhered to. 

Important Points to Remember

• Your model is not intended for use on public roads or congested  

areas where its operation can conflict with or disrupt pedestrian or 
vehicular traffic.

• Never, under any circumstances, operate the model in crowds of people. 

Your model is very fast and could cause injury if allowed to collide  
with anyone.

• Because your model is controlled by radio, it is subject to radio 

interference from many sources that are beyond your control. Since  
radio interference can cause momentary losses of radio control, always 
allow a safety margin in all directions around the model in order to 
prevent collisions. 

• The motor, battery, and speed control can become hot during use. Be 

careful to avoid getting burned.  

• Don’t operate your model at night, or anytime your line of sight to the 

model may be obstructed or impaired in any way.

• 

Most importantly, use good common sense at all times.

Batteries and Battery Charging

Your model uses rechargeable batteries that must be handled with care for 
safety and long battery life. Make sure to read and follow all instructions 
and precautions for charging and maintaining the batteries. It is your 
responsibility to charge and care for the battery packs properly. In addition 
to your battery and charger instructions, here are some more tips to keep 
in mind.
• Do not charge batteries inside of an automobile. Do not charge batteries 

while driving in an automobile. The charger is equipped with a long cord 
intended to allow the battery to be charged outside of an automobile 
when using the automobile’s auxiliary power socket. If the cord will not 
reach outside of the automobile, find another power source.

• Never charge batteries on wood, cloth, carpet or on any other  

flammable material.

• Do not operate the charger in a cluttered space, or place objects on top 

of the charger or battery.
