PRECAUTIONS FOR SAFE ENJOYMENT OF YOUR R/C CAR
For children under the age of 13, parental guidance is recommended when running.

ASSEMBLY PRECAUTIONS

• Do not assemble around small children. The parts can be dangerous if accidentally swallowed.

• Check the contents carefully before assembly. Please contact Customer Support if you happen to notice any defective or missing items.

• You will find the assembly process much easier by carefully reading through the manual, and familiarizing yourself with the instructions.

• Many different tools are required during assembly. For safety purposes, please use suitable tools.
  Exercise extra caution when using a sharp tool such as a hobby knife.

• Many different materials are used for the parts. Use extra care when handling parts with sharp edges, such as machined metal parts.

• When cutting plastic parts, watch for any flying parts.

• Try to assemble any rotating parts or drivetrain parts as smooth as possible.

• Bundle wires neatly away from the ground or any moving drivetrain components.
  Make sure that all wires are properly connected to prevent shorting.

• Unnecessary modifications may be unsafe and hinder performance.

• Always paint in a well ventilated area away from flames.

PRECAUTIONS BEFORE RUNNING

• Yokomo R/C cars are built for competition use, and some models may exceed speeds of 40km per hour. Practice common sense and run the car in open safe places, or R/C car tracks.
• Do not run the car on public roads with high amounts of traffic, or in areas that may cause an inconvenience to people in that area.
• R/C cars are controlled using a radio frequency. In a worst-case scenario, radio interferences may cause loss of control.
• If others near you are running R/C cars, confirm that they are not running on the same frequency.
• R/C cars do not like water. Avoid running on rainy days, or areas with water puddles. Exposure of the electronics to water may cause loss of control or damage to the electronics.
• The drivetrain of an R/C car consists of many moving parts like gears, belts, shafts, and tires. Avoid touching these areas when the battery is connected.
• Many parts of an R/C car will become hot after running. Allow the parts to sufficiently cool before conducting any maintenance.

BEGINNING A RUN

1. Place the R/C car on a stand so the wheels are off the ground.
2. Confirm that the speed controller switch is OFF, and connect the motor and battery.
3. Extend the transmitter antenna and turn the switch ON. (It is unsafe to use a transmitter with low voltage. Make sure that the transmitter batteries are good before running.
4. Turn the speed controller switch ON.

FINISHING A RUN

1. Turn the speed controller switch OFF.
2. Disconnect the battery.
3. Turn the transmitter switch OFF, and retract the antenna.

BATTERY USAGE

（Carefully read the instruction included with the batteries）

• When charging batteries, make sure that the surrounding area is void of anything highly flammable. Also avoid charging in high-temperature locations.

• When charging batteries, frequently monitor the charging status. In a worst case scenario, overcharging a battery may cause it catch on fire. If the battery reaches 50 degrees Celsius or more, stop charging.

• Batteries will become hot after running. Continuous use of the battery pack may result in damage to the cells. Allow the battery too cool down before
  re-charging.

• Please do not discard old battery packs in the trash. Although inconvenient, please locate a battery disposal center.

MOTOR USAGE

（Carefully read the instructions included with the motor.）

• Connecting a 7.2V battery directly to the motor can be very dangerous. This may cause the internal parts of the motor to break apart, causing some parts to fly out of the motor. To break-in the motor, safely secure the motor and run the motor at about 3-5V.
• Motors require periodic maintenance. Slower speeds and decreased run times may indicate a worn-out motor. Periodically clean the motor and change the brushes when needed.
• Choose a gear ratio that matches the power characteristics of the motor. Using a gear ratio unsuited to the characteristics of the motor will not only prevent the motor from performing at its optimum, but may even cause damage to the other electronics.
• Motors will generally become very hot after running.
  Continuous running will reduce the life of the motor. Allow the motor to sufficiently cool between each run.
