• Find another wheel labeled “Rear” and repeat the previous steps on the other
side to install the other rear wheel.
• Insert the axle cap.
• 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).
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.
Gap
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.
NOTE:
The front and rear wheels are different. For better aesthetics, mount all wheels
on the carriage so the rim design is consistent (for example, the rim design appears
clockwise).
4. SEAT BACK ASSEMBLY
• Gently turn the carriage body upright,
making sure not to damage the door
handles and undercarriage flourishes.
• Slide the seat back into the slots in the
plastic body, push until it clicks into
place. Use the screwdriver to tighten with
four 4x16 round head screws at the back
