8. Steering wheel failure
Under normal conditions, the main causes of steering wheel failure are:
(1) the chain above the front wheel is loose or broken, so replace the chain in time.
(2) If the connecting spline of steering wheel is loose, tighten the spline locking screw.
The spline is located above the chassis and at the bottom of the steering gear.
9. No dust
Check whether the vibration motor is damaged and whether the vibration dust chain
is loose or broken. If it is damaged, replace it. Check whether the relevant circuit and
switch button are normal. If damaged, replace it.
