Safety Conventions
The following safety messaging conventions are used throughout this document:
WARNING! Warns you about actions that could result in death or serious injury.
CAUTION! Warns you about actions that could result in minor or moderate injury.
NOTE
Indicates information considered important, but not related to personal injury.
Examples include messages regarding possible damage to the One S1 or
other property, or usage tips.
Important Safety Notices
Read and follow all safety notices.
WARNING!
• To replace parts on the One S1, you must read and follow all instructions and warnings in this manual.
• If servicing a One S1 on a raised surface such as a table, be sure to secure the One S1 so it cannot fall.
• Always power off the One S1 before performing any maintenance or installing any part or accessory.
Always unplug the power cord before performing any maintenance or installing any part or accessory.
• Do not use the battery if the case 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. If you experience any of the above, call
Segway Technical Support immediately at 1-866-473-4929, prompt #2.
• Observe and follow all safety information on the warning label found on the battery and all other labels.
• Use only charging devices approved by Ninebot or Segway and never attempt to bypass or override their
charging protection circuits.
• Do not wash the One S1 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 One S1 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 One S1 outdoors and away from ammable objects.
• As with all rechargeable batteries, do not charge near ammable materials. When charging, the batteries
heat up and could ignite a re.
• Always wear gloves when handling chemicals (such as lubricants, corrosion inhibitors, greases, or oils) to
reduce the potential for skin damage or irritation.
• When a procedure requires the use of safety glasses (such as those in which a mallet or solvent is used),
failure to wear eye protection could result in serious injury.
• Failure to adhere to these warnings could lead to serious injury, death, re, or damage to property.
CAUTION!
• When a repair involves removing, disconnecting, or handling electronic components, use best-practice
electrostatic discharge (ESD) control procedures to avoid damaging sensitive electronic components.

Introduction
Service Manual
Introduction
Purpose
The purpose of this manual is to provide instructions for servicing the
Ninebot One S1 by Segway.
Audience
This manual is written for authorized service technicians.
General Service Procedures
Before performing any service on the One S1, you must rst determine
which components may be damaged or malfunctioning. In some cases
this requires a simple visual inspection — as in the case of a cracked or
damaged housing. In other cases diagnostic equipment must be used
to troubleshoot the problem — as in the case of a vehicle limiting the
maximum speed to lower than expected.
No matter what the problem is, the service procedure is the same:
1. Identify — identify the symptoms.
2. Diagnose — determine which components may be malfunctioning.
3. Replace — replace the malfunctioning component(s).
4. Verify — operate the vehicle to verify the problem has been solved.
It may be the case that there are multiple problems affecting a One S1.
Try to isolate the problems and solve them one at a time.
Related User Materials
This document is a service manual intended for use by trained
technicians to service and repair the One S1. It does not contain
general operating information. The following additional user materials
may be needed for reference during service:

Please check www.segway.com for the latest user manual, and/or
contact Segway to conrm you have on hand the most recent service
publications.

Introduction
10 One S1
Control Board Connectors
Some One S1 connectors have a locking tab holding it in place. To
unplug/disconnect these connectors you must depress the locking tab
while pulling on the connector.
NOTE
When pulling on a connector it is possible to pull the socket as well. Be
careful not to pull the socket off the board.
Fasteners
Always tighten fasteners in a cross pattern to ensure that components
sit at against each other. Tighten fasteners to the torque specication
listed (if provided). If no torque specication is provided, tighten
fasteners securely, but do not overtighten.
NOTE
If a fastener falls into the housing/interior of the unit during service,
you MUST remove the fastener before turning ON or operating the
unit. A loose fastener could possibly cause a short or some other type
of mechanical failure.
ESD Protection
When a repair involves removing, disconnecting, or handling electronic
components, use best-practice electrostatic discharge (ESD) control
procedures to avoid damaging sensitive electronic components.
At a minimum, ESD protection should include an antistatic mat and an
antistatic wrist strap. Both these items must be properly grounded.
Power Tools
Do not use power tools when servicing the One S1. Tighten fasteners
to the torque specication listed (if provided). If no torque specication
is provided, tighten fasteners securely, but do not overtighten.

Batteries
Service Manual
Overview
There are two batteries, one on each side of the unit. Each battery
is accessed by opening the battery cover. A gasket underneath the
battery cover protects the batteries from the elements.
This component is not serviceable; if there is a problem with the
battery it must be replaced.
When to Replace
Replace when troubleshooting determines that the battery is
malfunctioning.
Safety
WARNING!
Always remove the batteries before servicing the One S1. Failure
to remove the battery could result in serious injury or death due to
electric shock.
WARNING!
After removing the batteries, press the ON/OFF button to discharge
any residual energy in the One S1. Failure to do so could result in
serious bodily injury from electric shock.
WARNING!
Do not allow any metallic object to touch the pins of the battery
connector. Shorting these pins could result in a hazardous release of
stored energy.
WARNING!
Do not use the battery if the case 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.
If you experience any of the above, call Segway Technical Support
immediately at 1-866-473-4929, prompt #2.

WARNING!
Remove BOTH batteries before performing any
internal service. Otherwise you risk serious injury or
death due to electric shock.
Tools Required
• Phillips screwdriver
Removal
Make sure the One S1 is powered off and the
charger is not connected.
1. Remove the battery cover (page14)
2. Use a Phillips screwdriver to remove the four
battery screws (Figure 5).
3. Unplug the black connector rst, then unplug the

Pull on the connectors, not on the wires. You
don’t want to pull the wires out of the connectors.
4. Follow the steps above to remove the battery
from the other side of the One S1.
WARNING!
Do not touch any internal electrical components
until after you have removed BOTH batteries and
pressed the ON/OFF button to discharge the
residual power. Failure to do so could result in
serious bodily injury from electric shock.
5. Press and hold the ON/OFF button until all
lights are off in order to discharge any power
remaining in the One S1.
