If you find that your front wheel is shaking or wobbling don't worry - all this requires is a very simple adjustment. First remove the black plastic wheel cover that sits above the front wheel held in place by four screws. Once removed, you will see a nut holding the front wheel in place. Then using a wrench, turn the nut a very small amount at a time until the wobble is gone. If the wheel becomes stiff that means you have tightened it too much and you will need to loosen the nut slightly until you have the maneuverability you need.
