OFNA Racing Nexx8 User Manual

IMPORTANT-READ THIS BEFORE RUNNING

1.Before Starting

•Please read manual carefulyl (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 seriously injured someone.

•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. But remember failsafe does not protect all power is lost

in vehicle.

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

4.Check Your Vehicle After Runing

•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

•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.

WARNING: To avoid a possible fire hazard, always unplug the battery. Do not leave your vehicle

unattended with the battery plugged in.
