IMPORTANT-READ THIS BEFORE RUNNING

1.Before Starting

•Please read manual carefully (With a parent, guardian or a responsible adult if necessary).

2.While Operating

•Any running area you choose must be dry. Do not run vehicle near any water or wet areas.

•Do not run on public streets. It is very easy to have the car run over or be damaged by hitting the curb.

•Do not operate the car in tight confined places. The vehicle is very fast and will easily hit something.

•Do not run near people or animals. The car is very fast and could easily hit someone if you are not an
expert driver.

•Do not operate the car at night. You will not be able to drive it safely.

3.Before Operating

•Make sure that all screws and nuts are properly tightened.

•Always use fresh batteries for your transmitter and receiver before running the car. If the radio does
not have full control of the car with steering, throttle and brake. Do not run it until corrected. Failure
to correct this will result in possible injury and damage to the car or property.
We strongly recommend using a failsafe.

•Please confirm the steering and throttle is at neutral position.

4.Check Your Vehicle After Runing

•Turn OFF receiver first, then transmitter. This will prevent the car from losing control.

•After running radio controlled car, it is necessary to perform routine maintenance.

5.Cautions for Safety

•If your model does not operate correctly, stop it and find the cause.

•Keep hands and tools away from moving parts.

WARNING: After each run, the model is hot, beware of getting burned.

IMPORTANT-READ THIS BEFORE RUNNING
