3. REAR WHEEL ASSEMBLY
• First, remove all washers and nuts from
the rear axle.
• Insert the rear axle through the hole in the
vehicle body as shown, making sure the
axle exposure at the left and right ends
are equal.
• Find a rear wheel marked with an “R”
and labeled with an “Rear”. Find the “R”
marking at the rear end of the vehicle body
to match this wheel and slide the wheel
onto the axle.
• 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 is acceptable.
• For your safety, insert a split pin into the
hole in the end of rear axle, and split it
using standard needle nose pliers. (Refer
to the drawings illustrated for front wheel at
page 9).
• Insert the axle cap.
• Find the other rear wheel, marked with an
“L” and labeled with and “Rear”. Find the
“L” marking at the rear end of the vehicle
body to match this wheel and slide the
wheel onto the axle. Secure this wheel with
the same steps as the other rear wheel
above.
2. FRONT WHEEL ASSEMBLY
• Turn the vehicle body upside down (this
should be handled carefully by two adults)
• Cut the tie on the front axle with scissors.
• Adjust the front wheel axle until the axle
clicks into position to ensure that it is
secure for safety (see Figure A).
• Remove washers and nuts from the front
wheel axle.
CAUTION:
To avoid pinching your
fingers, do not put your hand into the slot
when adjusting the front wheel axle.
• Fit a Ø19 washer onto the axle.
• Find a front wheel marked with an “R”
and labeled with an "Front". Find the “R”
marking on the front of the vehicle body to
match this wheel and slide the wheel onto
the axle.
NOTE
: Refer to the below drawing showing
"R" and "L" location on vehicle body.
• Fit a Ø12 washer and M10 locknut onto the
axle, then tighten it.
• Insert the axle cap until it clicks into place.
• Find the other front wheel, marked with an
“L” and labeled with and “Front”. Find the
“L” marking on the front end of the vehicle
body to match this wheel and slide the
wheel onto the axle. Secure this wheel with
the same steps as the other front wheel
above.
• Front wheels should spin freely;
if not, loosen nut slightly.

IMPORTANT! CHECK WHEEL GAP
After assembling any wheel onto the axles,
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, spin the wheel to check if the
wheel spins smoothly. If the wheel gets
caught or does not spin smoothly, the
friction may cause damage to the motor. Try
increasing the gap by removing one or two
washers to ensure the wheel spins smoothly.
NOTE:
If the wheel nuts are loose,
the wheels will not engage the
forward gear. Tighten the nut with
the socket wrench.
