2.2 Install the Handlebar and Control Shaft
Before installation, please find in the standard
accessories a set of 2 hexagon wrenches. Please
retain this tool kit; it is useful for maintenance and
transportation of the unit. A pair of work gloves is
recommended to protect your hands from dirt and
scratches. Take out the handlebar and control shaft,
insert the handlebar into the slot as shown below.
Fix them together using the small fixing nob. Then
install the handlebar and shaft assembly onto the
wheel assembly and fasten with the large fixing
knob. Make sure to install the control shaft with the
handlebar by lining the inner hole with the outer
hole.
