•If you are under 18 please read manual (with a parent, guardian or a responsible adult if necessary).

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

•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 space. The car 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.

•Radio-Check battery life before running the car. If the radio does not have full control of the car with

steering and/or throttle/brake, do not run until corrected. Failure to correct this will result in possible

injury and damage to the car or property.

•Please confirm the neutral throttle trigger position.

4.Check Your Car After Running

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

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

5.Battery Safety

IMPORTANT-READ THIS BEFORE RUNNING

•Please be careful when handling the battery. It will be hot after running. If the wire is frayed, a short

circuit can cause a fire.
