SAFETY PRECAUTIONS AND WARNINGS
Read and follow all manuals and safety precautions before use. Improper use can result in fire, serious injury
and damage to property. As the user of this product, you are solely responsible for operating in a manner that
does not endanger yourself and others or result in damage to the product or property of others. This model is
controlled by a radio signal subject to interference from many sources outside your control. This interference
can cause momentary loss of control, so it is advisable to always keep a safe distance in all directions around
your model as this margin will help avoid collisions or injury. • Never operate your model with low transmitter
batteries. • Always operate your model in open spaces away from full-size vehicles, traffic and people. • Never
operate the model in the street or in populated areas for any reason. • Carefully follow the directions and
warnings for this and any optional support equipment (chargers, rechargeable battery packs, etc.) you use. •
Keep all chemicals, small parts and anything electrical out of the reach of children. • Never lick or place any
portion of the model in your mouth as it could cause serious injury or even death. • Exercise caution when
using tools and sharp instruments. • Take care during maintenance as some parts may have sharp edges. •
Immediately after using your model, do NOT touch equipment such as the motor, electronic speed control and
battery, because they generate high temperatures. You may burn yourself seriously touching them. • Do not
put fingers or any objects inside rotating and moving parts, as this may cause damage or serious injury. •
Always turn on your transmitter before you turn on the receiver in the car. Always turn off the receiver before
turning your transmitter off. • Keep the wheels of the model off the ground when checking the operation of the
radio equipment.
