all times. Parents should ensure that children only use the electric ride-on toy
safely and within their age and physical limits.
Children should be made aware of all possible riding hazards and correct riding
behavior before they ride the electric ride-on toy and should be supervised by
an adult at all times. Please explain the following to them as often as necessary.

TOOLS REQUIRED:
1. FRONT AXLE ASSEMBLY
• Turn over the vehicle body and cut off the
plastic tie on the front wheel axle with
scissors.
• Remove the M5 screw, washer and nut
from the front wheel axle.
• Adjust the wheel axle so that the axle is in
the correct position as shown in diagram;
then reinsert the M5 screw and the Ø5
washer as shown, making sure the M5
screw goes through the holes in the metal
plates A and B (ensure plate A sites over
plate B as shown in the diagram and
indicated by a stopper, to avoid fingers
being trapped while steering), and tighten
securely with the nut under it.

2. FRONT WHEEL ASSEMBLY
3. REAR AXLE ASSEMBLY
4. DRIVING WHEEL ASSEMBLY
• Turn the vehicle body upside down.
• Remove all parts from front wheel axle.
• Fit a Ø12 washer onto the axle.
• Fit a bushing onto the axle.
• Slide a wheel onto the axle, and make the
bushing match inside the wheel.
• Fit another Ø12 washer and a M10 locknut,
then tighten it. (Note: Do not over-tighten)
• Insert the axle cap.
• Repeat above operation for the front
wheel on the other side.
• Turn the vehicle body upside down.
• Remove all parts from the rear axle.
• Insert the longer end of the rear axle
through the hole in the vehicle body as
shown, and ensure that the rear axle sits
well inside the vehicle body.
• Slide the gear box (standing at back of
vehicle body) onto the rear axle. Connect
motor and motor wire, and insert the
wires into car body first before you insert
the motor (Remark: “R” labeled gear box
should be fitted to the “R” labeled side of
vehicle body, “L” labeled gear box should
be fitted to “L” labeled side of vehicle
body.)
• Slide the driving wheel onto rear axle and
make it match up with the gear box.
• Insert a Ø12 washer onto the axle.
• While holding the rear axle with a 17mm
socket wrench, fit the M10 locknut to the
end of the rear axle with another 17mm
socket wrench. DO NOT over tighten;
the rear axle ends are supposed to be
exposed; 1-2 threads exposed can be OK.
• Insert the axle cap.

IMPORTANT! CHECK GAP AFTER ASSEMBLING WHEELS
5. STEERING COLUMN ASSEMBLY
• Turn the vehicle on its side as shown in diagram.
• Slide a Ø10 washer onto the steering column from the longer end.
• Insert the longer end of steering column shaft through the bottom hole in the
front of vehicle body until it sticks out of the hole in the dash.
• Slide a Ø10 washer onto the short end of steering column, then insert it
through the hole in the front axle linkage.
• Fit a Ø10 washer onto the short end of the steering column.
• Then insert a split pin into the hole in the short end of steering column, and
split it using standard slip joint pliers.
6. STEERING WHEEL ASSEMBLY
• Turn the vehicle body upright gently.
Remove the M5 x 35 machine screw and
M5 nut from the steering wheel with a
screwdriver.
• Insert the steering wheel onto the end
of the steering column, line up the hole
in the steering wheel and the hole in the
steering column, reinsert the M5 x 35
machine screw and M5 nut as shown
and tighten securely with a screwdriver.
After assembling any wheel onto the axles, make sure to
check the gap between the screw thread and the outside of
the wheel (refer to the adjacent diagram). If the gap is too
big, add two or three washers on the axle to the inside of the
wheel. After tightening the nut on the outside of the wheel,
please turn the wheel with your finger to check if the wheel
can run smoothly. This is a very important step because if
the wheel can run smoothly, it is ok; but if the nut presses
the wheel and the wheel can't run smoothly, the motor will
be broken easily! If the wheel does not run smoothly, you
will need to decrease one or two washers to make sure the
wheel can run smoothly!
Note: If the wheel nuts are loose, the wheels will not engage
the forward gear. Tighten the nut with the wrench.
