5 Safety Precautions
Operation Precautions

WARNING
 When using a Ni-Cd/Ni-MH battery to power your system, always charge and check the
battery voltage prior to operation. Should the battery discharge below the minimum voltage
level, control will be lost.
 Prior to operation always perform a range test. Even one abnormality in the R/C system
may cause loss of control.
[Range Test Procedure]
Have a friend hold the model, or place on a stand where the wheels or prop can not come
in contact with any object. Operate from a distance of about 100 feet. Be sure to check the
movement of each servo to make sure it follows the movement of the steering wheel and
throttle trigger. If the servos do not follow the commands from the transmitter or any type of
interference is detected, Do not operate the model.
 Never operate in the rain or run through puddles.
The transmitter, receiver, batteries and most servos, and speed controls are not water-
proof. Contact with any type of moisture or immersion in water or snow will cause damage
along with possible loss of control. Should any type of moisture enter any component of
the system, immediately stop using the R/C system and return it to our service center for
inspection.
 Do not operate when visibility is limited.
Should you lose sight of the model, a collision or other dangerous situation may occur.
 Do not operate near people or roads.
Do not operate on any pond when boats are present.
Do not operate near high tension power lines or communication broadcasting antennas.
Prior to the operation of any model be sure the area you plan to use is safe. Be aware of all
objects that may be in the path of your model. Do not operate the model where people or
any type of moveable object could stray in the path of your model. Control loss due to inter-
ference, component failure, loss of sight or low battery voltage could result in serious injury
to yourself and others as well as damage to your model.
 Do not operate when you are tired, not feeling well or under the influence of alcohol or
drugs.
Your judgment is impaired and could result in a dangerous situation that may cause serious
injury to yourself and others.
 (Turning on the power switches)
Always check the throttle trigger on the transmitter to be sure it is at the neutral position.
1. Turn on the transmitter power switch.
2. Turn on the receiver or speed control power switch.
(Turning off the power switches)
Always be sure the engine is not running or the motor is stopped.
1. Turn off the receiver or speed control power switch.
2. Then turn off the transmitter power switch.
If the power switches are turned off in the opposite order the model may unexpectedly run
out of control and cause a very dangerous situation.
