Important Safety Notices
Read and follow all safety notices:
To replace parts on the Ninebot ONE, you must read and follow all instructions and warnings in this
manual.
Always power off the Ninebot ONE before performing any maintenance or installing any part or
accessory. Always unplug the AC power cord before performing any maintenance or installing any part
or accessory.
Remove the Battery before performing any service on the Ninebot ONE.
Do not use the Battery if the exterior wrap/covering is broken or if the Battery emits an unusual odor,
smoke, or excessive heat, or leaks any substance. Avoid contact with any substance seeping from the
Battery. Batteries contain toxic and corrosive materials that could cause serious injury.
Observe and follow all safety information on the warning label found on the Battery.
Use only charging devices approved by Ninebot and never attempt to bypass or override their charging
protection circuits.
Do not wash the Ninebot ONE with a power washer or high pressure hose. Avoid exposure to heavy
downpours or extended periods of heavy rain (including during riding, storage, or while being
transported). Clean with soap and water and a soft cloth. Make sure that the Charge Port is dry before
you plug in the Power Cord.
Do not submerge the Ninebot ONE or Battery in water. If you suspect the Battery has been submerged
or experienced water intrusion, call Segway Technical Support immediately at 1-866-473-4929, prompt
#2. Until you receive further instructions, store the Ninebot ONE outdoors and away from flammable
objects.
As with all rechargeable batteries, do not charge near flammable materials. When charging, the
batteries heat up and could ignite a fire.
Always wear gloves when handling chemicals (such as lubricants, corrosion inhibitors, greases, or oils)
to reduce the potential for skin damage or irritation.
Failure to adhere to these warnings could lead to serious injury, death, fire, or damage to property.
