Check flywheel and add ball bearing oil
Check the flywheels (located on the rear axis) before riding. Make sure there
are no abnormal noises coming from the Space Scooter when moving the
board up and down. If there is an abnormal noise, flip the Space Scooter®
Junior upside down and add 3 to 5 drops of ball bearing oil between the gaps
of the flywheel and bearing. Wait for a minute to let ball bearing oil saturate
the flywheel. The user should add ball bearing oil approximately every month
to keep the flywheels running smooth and increase the Space Scooter’s
durability, even if there aren’t any abnormal noises coming from the Space
Scooter.
