loss of control, collision, and falls. To ride safely, you must read
and follow all warnings and instructions in the user guide.
WARNING: PINCH POINTS!
Keep fingers, hair, and clothing away from belts,
motors , wheels, and all moving parts
WARNING: RISK OF ELECTRIC SHOCK!
Do not open or tamper with electronics
housings, which also voids the warranty.
WARNING: AVOID WATER!
Your board is not water proof. Electronics,
bearings, and other components can be damaged.
Water damage is not covered under the warranty.
Please ride responsibly and respect those around you, both for
your safety and to help promote new sport and mode of
transportation.
WARNING: Do not ride board in environments, on inclines, or at
speeds where you would not be safely in control of an unpowered
longboard. In the event of wireless interference or battery fault,
you may need to rely on skating techniques like footbraking or
sliding to stop.
Always wear a helmet when riding. Avoid water, wet surfaces,
slippery/uneven surfaces, steep hills, traffic, cracks,tracks, gravel,
rocks, or any obstacles that could cause a loss of traction and
cause a fall. Avoid night riding, areas with poor visibility, and small
spaces.
