• DO NOT let any exposed battery contacts or wires touch each other.
This will cause the battery to short circuit and create the risk of fire.
• While charging, ALWAYS place the battery on a nonflammable surface
such as concrete.
• NEVER charge batteries on wood, cloth, carpet or on any other flammable
material.
• ALWAYS charge batteries in a well-ventilated area.
• REMOVE flammable items and combustible materials from the charging
area.
• DO NOT place objects on top of the charger or batteries.
• If any battery or battery cell is damaged in any way, do NOT charge,
discharge, or
use the battery.
• DO NOT disassemble, crush, short circuit, or expose the batteries or cells to
flame or
any other source of ignition.
• If a battery gets hot to the touch during the charging process, disconnect the
battery
from the charger and discontinue charging immediately.
• ALWAYS unplug the charger and disconnect the batteries when not in use.
• DO NOT leave the charger and batteries unattended while charging,
discharging, or
any time that the charger is ON with batteries connected.
If there are any signs of a malfunction or in the event of an emergency, unplug
the charger from the power source and disconnect the batteries from the
charger.
• REMOVE the batteries from your car before charging.
• DO NOT expose the batteries and charger to water or moisture.
• ALWAYS store battery packs safely out of the reach of children and pets.
• DO NOT charge batteries under ANY of the following conditions:
- Batteries that are hot to the touch.
- Batteries that are not expressly stated by the manufacturer to be suitable to
accept the power output (voltage and amperage) the charger delivers during
the charging process.
- Batteries that are damaged or defective in any way.
Examples of damage or defects include, but are not limited to, batteries with
dented cells, damaged or frayed wires, loose connections, fluid leaks, corro-
sion,
plugged vents, swelling, cell deformity, impact damage, melted components, or
any
other signs of damage.
- Battery packs that have been altered from original manufacturer configura-
tion.
- Non-rechargeable batteries (explosion hazard).
- Batteries that have missing or unreadable labels, preventing you from proper-
ly
identifying the battery type and specifications.

• Because your model is controlled by radio, it is subject to radio interference
from many
sources that are beyond your control. Since radio interference can cause
momentary
losses of radio control, always allow a safety margin in all directions around
the model in
order to prevent collisions.
• Range test your radio system in the area that you will be running the model to
ensure
that you have range that covers the area you want to drive.
After range testing, drive slowly in the area at first to make sure there is no
interference
that can cause momentary lapses of control.
• Always use new or freshly charged batteries in your model to maximize signal
power
output and range.
• The motors, batteries, and speed control can become hot during use.
Be careful to avoid getting burned.
• Choose the right location to drive. Your model is absolutely not intended for
use on
public roads or congested areas where its operation can conflict with or disrupt
pedestrian or vehicular trafc. This is to prevent the possibility of injury or death
resulting from collision with the model by another human being or animal.
• Do not drive the RC car by yourself. Bring a friend along to act as a spotter to
alert
you if a person or animal is approaching.
• Do not operate your model at night, or anytime your line of sight to the model
may be
obstructed or impaired in any way.
• Do not drive the model close to you where a mistake or loss of control could
cause the
model to collide with you or any spectator.
• Always carefully inspect your model for damage or loose components before
running.
Do not drive the model if it is damaged in any way. Tighten any loose hard-
ware.
• Never pick up the model by its tires or wheels. Always keep your hands
safely clear of
moving parts whenever the batteries are plugged in.
• Keep the RC car stored with the batteries removed, out of the reach of
children and
protected from access by any other unauthorized driver.
• Always disconnect the batteries in the model when it is not in use.
Never store the vehicle with batteries in the model, as this can cause a fire
leading to
property damage, serious personal injury or even death.
• Do not continue to operate the model with low batteries or you could lose
control of it.
Indications of low battery power include slow operation and delayed vehicle
response.
Stop immediately at the first sign of weak batteries. When the batteries in the
transmitter become weak, the red power light will begin to flash.
Stop immediately and install new batteries.
• Most importantly, use good common sense at all times.

Speed control
Your model’s electronic speed control (ESC) is an
extremely powerful electronic device capable of
delivering high current. Please closely follow these
precautions to prevent damage to the speed control
or other components.
• Disconnect the Battery: Always disconnect the
battery or batteries from the speed
control when not in use.
• Insulate the Wires: Always insulate exposed wiring
with heat shrink tubing to prevent
short circuits.
• Transmitter on First: Switch on your transmitter first
before switching on the speed
control to prevent runaways and erratic perfor-
mance.
• Don’t Get Burned: The ESC and motor can
become extremely hot during use, so be
careful not to touch them until they cool. Supply
adequate airflow for cooling.
• No Reverse Voltage: The ESC is not protected
against reverse polarity voltage.

MOTOR CARE
• Seat the motor brushes by driving smoothly on a flat surface during use of the first battery charge. Failing to
do so can greatly reduce motor performance and functional life.
• Prolong motor life by preventing overheating conditions. Undue motor wear results from frequent turns, stops
and starts, pushing objects, driving in deep water and tall grass, and driving continuously up hill.
Tighten the wheel
Tighten the wheel nuts before each
running session and periodically
check the tightness of the wheel
nuts while you are running.

not working
Rebinding the
remote control
with the car
Wheels are not
spinning properly
/coming off
Troubleshooting
Firstly, Plug in the charger
1. Solid red light on the charger = Charger is
plugged in.
2. Blinking red light on the charger = Charger is
defective.
1. Connect the li-ion battery.
2. Turn on the remote control first and within 3
seconds turn on the car as well.
3. Then remote control will bind to the car
automatically.
4. Please remember do not to touch the trigger
during binding.
1. Tighten the locknuts (Part Number 25-WJ02) that
are holding the wheels in place.
2. Check for any missing pieces like optical axis (Part
Number 25-ZJ09) and/or rear dog bone (Part Number
55-WJ02).
3. If all parts are intact, wheels still are not spinning
properly,the differential may be broken and needs to
be replaced.
If not successful, repeat this action 2-3 times.
Charger is normal,then plug in the battery
1. Blinking green light on the charger = Battery is
plugged in and charging.
2. Solid green light on the charger = Battery is
fully charged
3. Change from solid red light to flashing=Battery
is defective.
4. Blinking green light after 3-4hrs of charging =
Battery is defective.
Or please try charging the battery using the
second USB charger to determine which is
defective.

Troubleshooting
-
The RC car comes with a protective plastic film
that needs to be removed prior to using the car.
Reverse command
not responding
When the car is moving forward in order to go
in reverse please execute the following
commands on the remote:
first throttle push will bring the car to a stop and
in neutral mode. The second throttle push will
make the car go in reverse.
(please refer to Transmitter Instructions in this
User Manual)
RC car will not
pair with the
remote
1. Replace the batteries of the remote with brand
power.
2. The RC car has a thermal protection feature.
When the ESC detects that the temperature is
too high, it will automatically start thermal
protection.
Thus, it needs to be switched off and wait for a
few minutes to cool the temperature down.
3. Keep the remote and the car a few feet away
from each other while pairing.
4. Move away from large metal objects(vehi-
cles,etc.)
5. Remind the remote control with the car, and
check the light of the ESC(electronic speed
controller) and remote control, it should be a
solid red.
