Operating Limits

It is important that you familiarize yourself with the operating limits of the Segway PT. These limits are set to maximize rider safety while reduc­ing the risk of damage to the Segway PT. The Segway PT will perform better when you observe these limits.

Weight Limits for Riders and Cargo

Segway sets weight limits for two reasons:

• Rider safety

• To reduce the risk of damage to the Segway PT

Dynamic Weight Limits

To keep the Segway PT and rider upright, the Segway PT must always have enough power to be able to drive its wheels forward and backward.

WARNING

Exceeding the weight limits, especially when combined with other variables that require more power, will increase your risk of falling or damag­ing the Segway PT.

Variables that require more power include:

• Higher payloads (weight of rider and all cargo)

• Steeper slopes

• Bumpier surface conditions

• Higher speeds

• Abrupt maneuvers

The Segway PT monitors the amount of power being used and will activate safety alerts when it senses excessive power demands. It is important

that you learn to anticipate and recognize when the Segway PT is reaching the limits of performance.

14

NOTE:

For more information on recognizing and responding to Safety Alerts, see "Speed Limiter" (p. 52), "Stick Shake Warning" (p. 54), and "Safety
Shutdown" (p. 57).

Minimum Rider Weight

The rider’s weight must not be less than 100 lbs (45 kg). If the rider is below the minimum rider weight, he/she may not be able to ride safely
because he/she cannot shift his/her weight far enough back (behind the centerline of the wheels) to safely slow down and stop. This is
especially true when riding downhill. Also, riders below the minimum weight may not sufficiently activate the rider detect system, failing to
properly interact with the Segway PT’s balancing system.

Handlebar Cargo

The total weight of any handlebar payload plus any other attachments hanging from the handlebar must not exceed 10 lbs (4.5 kg).

WARNING

Exceeding the handlebar cargo limit interferes with the Segway PT's balancing ability and could cause the Segway PT to accelerate forward,
risking injury and/or damage to the Segway PT.

StructuralWeightLimits(MaximumPayload)

The maximum payload (rider plus all cargo) is 260 lbs (117 kg). Exceeding the maximum weight limit increases the risk of damage to the
Segway PT. Heavier payloads place greater stress on the Segway PT. Several factors affect the loads transmitted to the Segway PT:

• Skill level of the rider

• Payload (weight of the rider and all cargo)

• Surface condition (obstacle height, etc.)

NOTICE

Exceeding the rider or cargo weight limits, especially when riding on uneven terrain, could damage the Segway PT.

15

Maximizing Range

Maximum range distances are provided in Table 2 (p. 12). The range of your Segway PT is affected by many variables, including:

• Terrain: Riding on smooth, flat terrain improves range, and riding on hilly terrain and unpaved surfaces reduces range.

• Speed and Riding Style: Riding at a consistent, moderate speed will increase range. Frequent starting, stopping, acceleration, and

deceleration reduces range.

• TireInationPressure: Riding with tire pressures below the specified limit reduces range and can result in premature tire wear.

• Rider Weight and Cargo: Lighter riders with less cargo experience better range than heavier riders with more cargo.

• Temperature: Storing, charging, and riding in temperatures close to the median of the recommended temperature range improves

range. Riding in colder temperatures reduces range significantly.

• Battery Condition: Properly charged and maintained batteries provide greater range. Old, cold, heavily used, or poorly maintained
batteries provide less range (see Table 11, p. 86).

• Wind: Riding with a tailwind increases range. Riding against a headwind reduces range.

The Segway PT

This chapter describes how the PT works. It includes:

• Information about PT components and subsystems

How the Segway PT Works

The PT works like the human body, using technology called dynamic
stabilization to maintain its balance and move forward or backward. When
walking, if you lean forward, you take a step forward to keep your balance.
If you lean back, you step back. On a PT when you lean forward or back the
machine powers the Wheels in the direction that you lean.

When you lean, your center of gravity moves beyond the contact patch (the
place where the tire contacts the ground) causing the PT to tilt. The PT’s
systems sense this change, powering the Wheels to keep them underneath
you.

When you pivot the LeanSteer Frame left, the PT turns left. When you pivot
the LeanSteer Frame right, the PT turns right. To turn the PT, point the
LeanSteer Frame in the direction you want to go, keeping the Handlebar in
line with your body. When the LeanSteer Frame is centered, the PT travels
straight ahead.

The PT’s dynamic stabilization technology balances forward and backward
but not side-to-side. If you tip the PT onto one Wheel, it will not dynamically
bring itself underneath you and it could fall over. You are responsible for
maintaining side-to-side stability while riding the PT. To do this, keep your
body aligned with the LeanSteer Frame. Lean into turns and lean uphill when
riding across a slope to maintain side-to-side balance.

Figure 11: Leaning Forward and Back

How the Segway PT Works (cont.)

Slow Speed Roll Compensation Feature

The PT utilizes a feature called Roll Compensation that separates steering

input from terrain changes. This allows the rider to ride in a straight line
over uneven terrain by keeping the LeanSteer Frame oriented straight up
and down. When riding at low speeds and on slopes, Roll Compensation
is reduced, allowing for more precise control at slow speeds as well as
reducing steering drift during power on. As the rider's speed increases, Roll
Compensation increases, as well.

Beginner Setting Mount/Dismount Feature

The Segway PT LeanSteer technology was designed to provide responsive

steering. The software includes a feature to help new riders easily learn
how to mount and dismount the PT without unintentionally initiating a turn.
When the PT is in Beginner Setting and the rider has less than two of the
four Rider Detect Sensors (see "Rider Detect Sensors," p. 33) engaged, and
the PT is moving neither forward or backward, the sensitivity of the LeanSteer frame is 15% of normal operation. When the PT is in Beginner
Setting and the rider has two feet on the PT, and the PT is moving neither forward or backward, the sensitivity of the LeanSteer frame is 55%
of normal operation. As the PT's speed increases, the sensitivity of the LeanSteer frame is gradually increased.

NOTE:

The Beginner Setting Mount/Dismount Feature is only activated when the PT is in Beginner Setting (turtle icon displayed on Infokey Controller).

For more information on switching between Beginner Setting and Standard Setting, see "Beginner Button Functions," p. 43.

Segway PT Components and Subsystems

WARNING

All Segway PT parts must be approved by Segway, and properly installed.
Never attempt to stand on a PT without the LeanSteer Frame attached and
secured. Using your PT without all parts properly installed could damage your
PT and result in serious injury from loss of control, collisions, and falls.

WARNING

Do not modify the Segway PT. Modifications to the PT could interfere with the
operation of the PT, could result in serious injury and/or damage, and could
void the Segway PT Limited Warranty.

The Segway PT includes the following components and subsystems (see

Segway PT Components and Subsystems (cont.)

The PT has been designed with concern for the safety of the rider and those who may be nearby. Redundant subsystems maintain controlled

operation of the PT in the unlikely event of a component failure. If one component in a subsystem fails, the other component continues to
operate, allowing you to come to a complete and safe stop before stepping off. The PT has five redundant subsystems: Controller Boards,
Motors, Batteries, the Balance Sensor Assembly, and LeanSteer Sensors.

LeanSteer Frame/Handlebar

Ensure the following:

• The Handlebar is attached to the LeanSteer Frame.

• The LeanSteer Frame is attached to the Powerbase.

• The Handlebar is adjusted to the appropriate height.

See "Attach the LeanSteer Frame" (p. 19) for detailed installation instructions.

The LeanSteer Frame pivots at the base to control left/right direction of the PT. If you lean to the left while holding the Handlebar, the LeanSteer

Frame pivots and the PT turns left. If you lean to the right while holding the handlebar, the LeanSteer Frame pivots and the PT turns right.
Always lean left or right in coordination with the LeanSteer Frame.

Tire/Wheel Assembly and Fenders

Ensure that Tires are inflated to the proper tire inflation pressure as specified in "Segway PT Specifications" (p. 12).

Tires and Wheels are shipped as an assembly. Do not remove the Tire from the Wheel.

The Fenders on the PT are designed to protect the rider from debris and to safeguard the rider while leaning into turns.

WARNING

Do not remove fenders or ride a Segway PT that has its fenders removed. Doing so could result in loss of control and/or serious personal injury.

28

Powerbase

The Powerbase consists of the following parts:

• Mats/Console

• Rider Detect Sensors

• Controller Boards

• Motors

• Balance Sensor Assembly

• Running Lights

Mats

Your PT comes with two Mats installed. These Mats protect the Rider Detect
Sensors located beneath them, as well as provide a comfortable surface on
which to stand. Mats should be secured in place prior to riding.

For more information, see "Remove/Install the Mats" (p. 114).

Console

The Console is located behind the LeanSteer Frame and between the two
Mats.

There are two sets of Indicator lights on the Console (see Figure 15):

• Balance Indicator lights provide visual feedback about whether or

not the PT is ready for you to step on.

• Charge Indicator lights provide Battery charge status information

for the PT Batteries when the Segway PT is plugged into AC power.

Rear Running lights

Segway PT Components and Subsystems (cont.)

Balance Indicator Lights

Five Balance Indicator lights are located on the Console. These lights provide
visual feedback about the balancing status of the PT, and help the rider de­termine when it is safe to step onto the Mats (see Figure 16).

Table 3 describes the Balance Indicator light patterns, and the correspond­ing balance status of the PT.

Red Balance Indicator lights indicate that the Powerbase or LeanSteer Frame
are tilted, and the PT is not ready to be stepped on:

• One red left or right Balance Indicator light

Pivot the LeanSteer Frame in the opposite direction of the red light,
until the LeanSteer Frame is vertical, and the red Balance Indicator
lights are replaced by one green Balance Indicator light in the center.

• One red front or rear Balance Indicator light

Tilt the Powerbase in the opposite direction of the red light, until the
Powerbase is level, and the red Balance Indicator lights are replaced
by one green Balance Indicator light in the center.

• Two adjacent red Balance Indicator lights

Move both the LeanSteer Frame and the Powerbase in the opposite
direction of the lights until the red Balance Indicator lights are re­placed by one green Balance Indicator light in the center.

• Five red Balance Indicator lights

Ensure LeanSteer Frame is vertical, Powerbase is level, Wheels
are not moving, and wait until the red Balance Indicator lights are
replaced by one green Balance Indicator light in the center.

Red

Figure 16: Balance Indicator Lights

30

Green Balance Indicator lights indicate that the PT is ready to be stepped on,
or that a rider is already on:

• One green Balance Indicator light in the center

The PT is in Standby Mode, ready for the rider to step on.

• Five green Balance Indicator lights pulsing

The PT is in Riderless Balance Mode, ready for the rider to step on.

• Four green Balance Indicator lights rotating

The PT is in Balance Mode with a rider on.

Balance Mode/Riderless Balance Mode

You ride your PT in Balance Mode. In this mode, the PT detects when you lean
forward or backward, or tilt the LeanSteer Frame left or right, and it moves its
Wheels in response to your movements. The PT also has a Riderless Balance
Mode, which allows you to slowly move the PT when you are not riding it. Step
down off the PT, and walk with your PT in Riderless Balance Mode to move
around obstacles, stairs, or terrain that is difficult to navigate or dangerous
to rider over. When the PT is in Riderless Balance Mode, it is important to
hold onto the Handlebar to prevent the PT from moving on its own.

You know your PT is in Balance Mode or Riderless Balance Mode when the
Balance Indicator lights on the forward part of the Console are pulsing
or rotating green and your InfoKey Controller displays a happy face. For
information on how to put your PT into Balance Mode, see “Riding Your
Segway PT,” p. 61.

Battery Charge Indicator Lights

Two Battery Charge Indicator lights on the Console indicate the charge
status of the Batteries when the PT is plugged in. The front Battery Charge
Indicator light corresponds to the front Battery and the rear Battery Charge
Indicator light corresponds to the rear Battery (see Figure 17).

For more information, see "Battery Charge Indicator Lights" (p. 89).

Rider Detect Sensors

WARNING

To prevent a riderless PT from traveling on its own, never let go of it while it is
in Balance Mode. It will travel some distance on its own before shutting down,
risking injury to others and damage to the PT.

WARNING

Never place anything on the Mats, except your feet. Doing so could interfere
with the Rider Detect Sensors and allow the PT to travel on its own, risking
running into a person or property, and causing injury or damage.

The PT has four sensors located beneath the Mats. Rider Detect Sensors
detect the presence or absence of a rider while the PT is powered on.

When your feet are properly positioned on the Mats, all four Rider Detect sen­sors depress, allowing the PT to operate normally in Balance Mode.

If fewer than three Rider Detect sensors are depressed while riding, the PT
reduces the top speed limit regardless of whether Beginner Setting is enabled
or not. Once your feet are properly positioned again, the PT regains full per­formance.

If the PT is moved too quickly while in Balance Mode and none of the Rider
Detect Sensors are depressed, the PT will give the Stick Shake Warning before
exiting Balance Mode and transitioning to Standby Mode.

Rider Detect Sensors

Figure 18: Rider Detect Sensors

33

Segway PT Components and Subsystems (cont.)

Controller Boards

The two Controller Boards receive input from the PT’s Batteries, Motors, Rider
Detect Sensors, LeanSteer Sensors, rate, and tilt sensors. Based on this input,
the Controller Boards send commands to the Motors that turn the Wheels.

If the system senses a malfunction in a critical component or a Battery that is
depleted beyond its safe limit, the PT will perform a Safety Shutdown.

For more information on Safety Shutdown, see "Safety Shutdown" (p. 57).

Figure 19: Controller Board Location

34

Motors

Each Wheel is independently driven by redundant, high-speed electric Motors
that are quiet and efficient. Each Motor is computer controlled to precisely
regulate the PT’s motion.

Each Motor is wound as two separate electrical circuits, capable of indepen­dent operation, acting as one mechanical entity. If either winding in a Motor
fails, the PT will perform a Safety Shutdown.

For more information on Safety Shutdown, see "Safety Shutdown" (p. 57).

Figure 20: Motor Location

35

Segway PT Components and Subsystems (cont.)

Balance Sensor Assembly

The Balance Sensor Assembly contains five angular rate sensors (solid state
gyroscopes) and two tilt sensors. The Balance Sensor Assembly sends infor­mation about the PT’s orientation to the Controller Boards. All sensors are
constantly monitored by the PT to ensure each is operating correctly. If one
of these sensors fails, the PT will perform a Safety Shutdown.

For more information on Safety Shutdown, see "Safety Shutdown" (p. 57).

Figure 21: Balance Sensor Assembly Location

36

Running Lights

The PT Running Lights, located at the front and rear of the Powerbase (see
Figure 22), are intended to make the PT and rider more visible to others in
low-light conditions. The Running Lights turn on automatically and stay on
until the PT is powered down.

PT Running Lights are not user-serviceable; if there are any problems with
the Running Lights, contact your Segway dealer.

WARNING

To ride safely, you must be able to clearly see what is in front of you and you
must be clearly visible to others.

Figure 22: Running Lights

37

Batteries

The two PT Batteries are sealed units (when properly installed) that require
no maintenance other than proper charging and storage. The Batteries are
interchangeable and can each be installed in either the front or rear of the
Powerbase. For the PT to operate, both Batteries must be installed, and both
must be of the same chemistry/manufacture type. If one Battery fails or is
depleted beyond its safe limit, the PT will perform a Safety Shutdown.

For more information on Safety Shutdown, see "Safety Shutdown" (p. 57).

Activating the Training Safety Shutdown

WARNING

Before you demonstrate a Safety Shutdown for training purposes, you must
read "Safety Shutdown" (p. 57) and watch the Safety Video.

The purpose of demonstrating a Safety Shutdown is to introduce the rider to
the experience while in a predictable, controlled environment with a spotter.

1. Make sure the PT is in Balance Mode.

2. The rider should stand on the Mats with the PT remaining stationary.

3. The spotter should firmly hold the PT, ready to keep it steady and
stationary when the Safety Shutdown begins.

4. A third person should hold the InfoKey Controller, and confirm that
both the rider and the spotter are ready.

5. The third person may then press and hold both the Information Dis­play button and the Power/Standby button simultaneously until the
Safety Shutdown initiates. Figure 26 shows the InfoKey Controller
display during a training Safety Shutdown.

6. The spotter must continue holding the PT so it does not move.

7. The rider must step off the PT before 10 seconds elapse.

In a non-training Safety Shutdown, the rider has approximately 10 seconds
from the start of the Safety Shutdown to come to a controlled stop and step
off. After 10 seconds, the PT will immediately shut down when the Wheels
reach zero speed.

Safety Alerts

This chapter describes the Segway PT’s safety alerts. The safety alerts include:

• Speed Limiter

• Stick Shake Warning

• Safety Shutdown

It is important that you recognize these alerts and know how to respond appropriately before you ride your PT.

WARNING

Read and follow all the instructions in the User Manual and watch the Safety Video for important safety information about the Speed Limiter,
Stick Shake, and Safety Shutdown safety alerts.

NOTE:

Not every safety issue triggers an alert. For additional safety tips and guidelines, see "Avoiding Hazards" (p. 62).

51

Speed Limiter

When you approach the maximum allowed speed, the PT’s Speed Limiter will
push the Handlebar back to slow you down (see Figure 27).

WARNING

Riding against the Handlebar can cause loss of control, collisions, falls, and
injury.

The PT’s Speed Limiter is an alert that you are moving too fast! When the
Speed Limiter pushes the Handlebar back, stop leaning forward and slow
down. Always leave a gap between yourself and the Handlebar as shown in
Figure28. Once you slow to a speed that the PT determines is safe, it will
resume normal operation and riding position.

The speed at which the Speed Limiter pushes the Handlebar back depends
on a variety of factors including riding style, terrain, payload, whether or not
the Beginner Setting is enabled, Battery condition, foot positioning, and other
factors.

Figure 27: Speed Limiter

52

Figure 28: Gap Between Rider and Handlebar

NOTE:

Conditions that may cause the Speed Limiter to activate when you are travel­ing at less than the maximum speed allowed for your operating mode include:

• Riding up or down a steep hill

• Riding on bumpy terrain

• Riding with fewer than three Rider Detect Sensors depressed

• The first few seconds after you power on and step on the Powerbase

• Low Battery charge

• Batteries that are too hot or too cold

• Riding down a hill with fully charged Batteries

Because of regenerative charging, if the Batteries are fully charged, the PT will
activate the Speed Limiter to avoid overcharging.

Table 6 shows the icons that display on the InfoKey Controller when the
Speed Limiter is engaged at a speed lower than the top speed set by the In­foKey Controller. This table also describes the error that has occurred and the
recommended action you should take.

Stick Shake Warning

One of the ways that the PT notifies you when you are at risk of falling is by
shaking the Handlebar and making growling noises. This is called the Stick
Shake Warning. The Stick Shake Warning can occur in conjunction with, or
independent of the Speed Limiter and Safety Shutdown alert, depending on
your riding situation (see Figure 29).

Rider On

If the Stick Shake Warning occurs while riding, slow down. If the Stick Shake
Warning persists, come to a stop and safely step off the PT. Do not attempt to
ride again until the condition that caused the persistent Stick Shake Warning
has been identified and corrected. If the Stick Shake Warning occurs while
you are stopped or stuck, step off immediately and do not attempt to ride
again until:

• You are clear of all obstacles and slopes.

• You are certain that you did not experience a Safety Shutdown.

For additional information, see "Safety Shutdown" (page 57).

Figure 29: Stick Shake Warning

54

When riding, the Stick Shake Warning occurs if you demand too much
power from the PT. The Stick Shake Warning can happen when riding on a
steep slope, over rough terrain, against an obstacle, or when accelerating
or decelerating abruptly. The Stick Shake Warning also occurs if you ride
backward too fast or if you try to step on the PT when it is not ready to
balance. The Stick Shake Warning is more likely to occur when your Batteries
are low, cold, heavily used, or poorly maintained because there is less energy
available to keep you balanced.

Table 7 lists possible causes of the Stick Shake Warning and recommended
actions to take when the Stick Shake Warning occurs with a Rider on the
Mats.

Stick Shake Warning (cont.)

Rider Off

You do not have to be riding the PT for the Stick Shake Warning to occur. The
Stick Shake Warning occurs if the PT is moved too quickly while in Riderless
Balance Mode. Riderless Balance Mode is when the PT is in Balance mode
without a rider standing on the Powerbase. The Stick Shake Warning also
occurs if the Wheels spin as you pull the PT over a curb or up stairs.

Table8 lists possible causes of the Stick Shake Warning and recommended
actions to take when the Stick Shake Warning occurs with no Rider on the
Mats.

Table8:StickShakeWarningWithNoRideronMats

Possible Causes Recommended Action

Moving a PT too
quickly with no rider
on the Powerbase
while in Riderless
Balance Mode.

Stepping on the PT
when it is powered
on, but not ready for
you to step on.

When moving your PT in Rider­less Balance Mode, you must
move slowly and carefully. Always
keep the PT below you (lead it up
stairs or slopes and keep it below
you when descending stairs or
slopes) (p. 78).

Step off, center the LeanSteer
Frame, and level the Powerbase.
Once the center Balance Indica­tor light turns green (p. 69), step
on again.

Safety Shutdown

WARNING

Do not get back on the Segway PT after a Safety Shutdown until the condition
that caused the Safety Shutdown has been identified and corrected.

WARNING

Never restart and ride your Segway PT after it has indicated an empty Battery
condition or performed Safety Shutdown due to low Battery. The PT may not
have enough power to keep you balanced, especially if you demand a lot of
power at once. If you restart and continue riding, you risk falling. Also, you
risk damaging your Batteries, resulting in reduced Battery life and capacity.

If the PT detects a fault in any of its redundant systems or a Battery is
depleted beyond its safe limit, it performs a Safety Shutdown (Figure 30).

When a Safety Shutdown occurs, the PT automatically reduces its speed,
gives the Stick Shake Warning (shakes the Handlebar and makes growling
noises), flashes the Balance Indicator lights, emits a warning tone, and the
InfoKey Controller displays an unhappy face.

You have approximately 10 seconds from the start of a Safety Shutdown
to come to a controlled stop and step off. After 10 seconds, the PT will
immediately shut down when the Wheels reach zero speed.

If a Safety Shutdown occurs:

1. Immediately come to a controlled stop.

2. Carefully step off one foot at a time.

Figure 30: Safety Shutdown

Safety Shutdown (cont.)

WARNING

Theft detection systems, such as the type used in some libraries and retail
stores can interfere with the Segway PT’s ability to balance and/or cause the
PT to perform a Safety Shutdown. Do not ride within 5 feet (1.5 meters) of
any theft detection system.

Table 9 shows the InfoKey Controller icon that displays when a Safety
Shutdown occurs. The table also describes the recommended action you
should take.

Table 9: Safety Shutdown

Display Icon Description Recommended Action

The system has detected a fault
and is slowing to zero speed

If a Safety Shutdown occurs:

Do not resume use of your PT after a Safety Shutdown has occurred
until you have identified and corrected the condition that caused it.

See "Troubleshooting the Segway PT" (p. 119).

Figure 31: Security Systems

1. Immediately come to a controlled stop.

2. Carefully step off one foot at a time. You have approximately
10 seconds from the start of the Safety Shutdown to come to a
controlled stop and step off the Powerbase.

58

Empty Battery Condition

The PT notifies you of a pending empty Battery condition before starting a Safety Shutdown. An unhappy face icon displays on the InfoKey
Controller, the PT’s speed is limited, and the PT emits a warning tone.

Whenever the PT notifies you of a pending empty Battery condition, come to a controlled stop and safely step off of the PT before the Safety
Shutdown begins.

Table 10 shows the InfoKey Controller icon that displays when a pending empty Battery notification occurs. The table also describes the
recommended action you should take.

NOTE:

In some cases, old, cold, heavily used, or poorly maintained Batteries may develop a high resistance condition. This can cause a pending
empty Battery condition to occur even if the Batteries were recently charged.

Table 10: Empty Battery Condition

Display Icon Description Recommended Action

The system has detected and
notified you of a pending empty
Battery condition (empty PT
Battery charge level shown).

Riding Your Segway PT

This section describes how to ride the Segway PT. It discusses riding for the first time and gives guidelines and helpful hints for all rides. Follow
these steps to learn to ride your PT. It is important that you practice riding in a controlled, familiar environment until you are comfortable using
your PT and InfoKey Controller.

Before riding, make sure your PT is assembled and charged. See "Assembling Your Segway PT" (p. 17), and "Charging Your Batteries" (p. 87).
Inspect your PT before each use (see "Pre-Ride Checklist" on the inside back cover of this manual). Do not ride if any part is loose, damaged,
or if the Tires are not properly inflated. See "Maintaining Your Segway PT" (p. 97). Do not wear loose clothing or jewelry that could get caught
in the PT.

Riding Form

Your posture and stance affect your ability to ride safely:

• Be alert. Scan both far ahead and in front of the Wheels—your eyes are your best tool for safely avoiding obstacles and slippery sur­faces.

• Keep a firm grip on the Handlebar, your legs loose, and knees and elbows bent. This helps you maintain your balance over rough terrain.

• Leave a gap between yourself and the Handlebar. Do not lean over or into the Handlebar. Leaning over or into the Handlebar dramati-

cally increases the risk of collisions, falls, and loss of control.

• Keep your feet centered on the Mats.

• Practice controlled stopping.

• Keep your body aligned with the LeanSteer Frame and lean into turns.

• Point the LeanSteer Frame in the direction you want to travel.

• Make sure the Handlebar is set to the correct height. See "Adjust the Handlebar Height" (p. 21).

61

Avoiding Hazards

The PT is highly maneuverable and allows you to easily navigate around ob­stacles. However, to prevent the loss of traction, you must always be care­ful when riding and learn to identify and avoid slippery, icy, or wet surfaces,
loose materials (sand/gravel), steep slopes, and obstacles. Stop and step off
your PT and use Riderless Balance Mode (p. 79) to move your PT over unsafe
surfaces or terrain.

Avoiding Slips

The PT Tires must be able to grip the ground for the machine to stay upright!
Slips occur when the tires lose traction, potentially causing loss of control and
a fall. Abrupt maneuvers, and riding over slippery surfaces, loose objects and
materials, or steep slopes can cause the tires to lose traction.

• Avoid abrupt maneuvers, such as fast stopping or starting.

• Avoid riding on slippery surfaces such as snow, ice, wet floors, wet

grass, or any other surface that might cause slipping.

• Avoid riding over loose objects or materials such as small branches,
litter, or small stones.

• Use caution when riding over any terrain change such as pavement
to grass, or over a threshold or speed bump.

• Avoid riding on steep slopes. Maintain Tire contact with the ground.

Figure 32: Navigate Around Obstacles

62

Figure 33: Avoid Slips

Avoiding Trips

Trips occur when the PT’s Wheels or Powerbase encounter an obstacle or ter­rain change that prevents the PT from moving, bringing it to an abrupt stop
and potentially causing a fall.

• Avoid holes, curbs, steps, and other obstacles.

• Avoid riding over any surface where the bottom of the PT may strike

any object.

• Use caution when riding over any terrain change such as pavement
to grass, or over a threshold or speed bump.

Avoiding Tips

The PT balances front to back but not side-to-side. You are responsible for
maintaining side-to-side balance by leaning into turns. If you fail to actively
maintain this side-to-side balance, the PT can tip sideways and fall.

• Avoid riding across steep slopes.

• Lean into turns and lean uphill when riding across gentle slopes.

• Keep the LeanSteer Frame vertical when riding across a slope.

• Avoid turning on slopes or ramps.

• Never let go of the Handlebar when riding across a slope. The PT will

turn downhill and you could lose your balance.

AvoidingTips(cont.)

• Stay centered on narrow sidewalks or elevated paths.

• Avoid turning when maneuvering backward.

• Make sure that one Wheel does not drop off a curb.

Figure 36: Do Not Drop a Wheel off a Curb

64

Step 1: Preparing for Your Ride

To prepare for your first ride:

1. Select an appropriate area for your first ride. This area may be
indoors or outdoors and should measure at least 12 feet by 12 feet
(4 meters by 4 meters). It must have a level, smooth riding surface
with good traction and should be free of obstructions and away
from vehicles, bicycles, pets, small children, and other distractions.

2. You will need a spotter who has studied all the instructions and
warnings in this manual and the Safety Video to help you and assist
you with the instructions.

3. Put on your helmet and fasten and adjust the chin strap in
accordance with the helmet manufacturer’s instructions.

4. Move the PT to the center of the riding area.

5. Adjust the Handlebar height. See "Adjust the Handlebar Height"
(p. 21).

6. Familiarize yourself with the icons that may be displayed on the
InfoKey Controller. See "Using the InfoKey Controller" (p. 41).

Figure 37: First Ride Requires a Spotter

Figure 38: ALWAYS Wear a Helmet!

65

Step 2: Powering On the Segway PT

Using the InfoKey Controller, power on your PT by pressing the Power/
Standby button. The Power/Standby button is located on the bottom left­hand side of the InfoKey Controller.

You will hear a tone from the PT and the Balance Indicator lights will illuminate
to indicate the power is ON and the PT is in Standby Mode.

WARNING

Do not step onto the PT yet! The PT is powered on, but is not balancing.

Power/Standby button

Figure 40: Balance Indicator Lights

Step 3: Confirming the Beginner Setting

Ensure the Beginner Setting is enabled by confirming the Turtle icon is dis­played on the InfoKey Controller.

WARNING

For your first ride, the Segway PT is set to operate exclusively with the
Beginner Setting enabled. If the Turtle icon does not display, DO NOT ride the
PT until you enable the Beginner Setting. See "InfoKey Controller Buttons
and Display" (p. 39).

For additional information on what to do if you do not see the Turtle icon
on the InfoKey Controller, see "Unlocking and Locking the Beginner Setting"
(p. 48).

WARNING

Do not step onto the PT yet! The PT is powered on, but is not balancing.

Figure 41: Confirm the Beginner Setting

67

Step 4: Before Stepping On

The Segway PT is on, but it is not balancing. While standing behind the PT,
center the Handlebar and level the Powerbase. Use the Balance Indicator
lights to help you. If any of the four outer Balance Indicator lights are red, tilt
the Powerbase or Handlebar in the opposite direction of the light(s). When
the PT is ready to enter Balance Mode, the center Balance Indicator light
will light up green. Make sure your InfoKey Controller is installed in the Dock
prior to stepping on.

When the center Balance Indicator light is green, the PT is in Riderless
Balance Mode, ready for you to step onto the Mats (see Table 3: Balance
Indicator Light Patterns, p. 31).

Figure 42: Ensure Balance Indicator is Green

68

Step 5: Stepping On

Before you attempt to step on for the first time:

• Have your spotter stand in front of the PT, face you, and hold the
Handlebar securely with both hands. Your spotter should be pre­pared to firmly hold the PT to keep it from moving.

• Remember, the PT will move forward, backward or turn if you move
the Handlebar. Avoid pushing, pulling, or leaning the Handlebar as
you step on.

• Confirm the center Balance Indicator light is green.

To step onto the PT:

1. Hold the Handlebar with both hands.

2. Place just one foot on the Mat.

3. Slowly transfer your weight to your foot on the Mat. As you step up,
look forward and not down.

4. Slowly, while not moving the Handlebar, raise your back foot off the
ground and place it on the Mat. Stay calm and relaxed. Look forward.

NOTE:

Some people rock back and forth involuntarily when they step on.

5. If you feel unstable, step off the PT, one foot at a time, and pause
before stepping back on. The spotter should continue holding firmly
the entire time, and be prepared to keep the PT from moving as you
step on or off.

Step 5: Stepping On (cont.)

Figure44 shows the displays that appear on the Console and the InfoKey
Controller as you step onto the PT.

Keep the Powerbase level to remain stationary. The correct position for stand­ing in place is shown in Figure45.

Ready for rider to step on the PT Rider on PT in Balance Mode

Figure 44: Stepping On

70

Figure 45: Keep the Powerbase Level to Remain Stationary

Step 6: Moving Forward and Backward

The Segway PT moves forward and backward in response to changes in your
position. When standing on the Powerbase, to move forward or backward:

1. With your spotter available to assist you, slowly lean forward and
feel the PT move forward. Then stop leaning forward and feel it slow
down and stop. Do this a few times.

WARNING

Avoid rocking back and forth or shifting your weight abruptly, as this could
result in a loss of traction and cause a fall.

2. Look behind you and then slowly lean back and feel the PT move
backward. Then stop leaning back and feel it slow down and stop. Do
this a few times.

NOTE:

You should not ride backward except to maneuver a few feet. In­stead, turn in place, then ride forward.

3. With your spotter standing close by, practice going forward and
backward a short distance in each direction. Be careful not to run
the Wheels into any wall or object. This could cause you to fall.

WARNING

Do not turn or go fast when maneuvering backward.

Figure 46: Moving Forward and Backward

71

Step 7: Stopping

Stop the Segway PT by shifting your weight away from the direction you are
moving. To stop the PT:

1. When you are moving forward, gently shift your hips back (as if you
are preparing to sit down) to bring the PT to a stop.

2. Once stopped, center your weight over the Powerbase to remain sta­tionary. If you continue to lean back, you will move backward.

3. Practice choosing a spot on the ground, and coming to a smooth
controlled stop at that spot. Then remain stationary.

NOTE:

Use a sit-down motion to stop, by keeping your shoulders aligned over your
hips and shifting your weight backward.

WARNING

Always perform a controlled stop. Avoid abrupt stops. Come to a controlled
stop by gently shifting your weight away from the direction of movement.
Avoid abrupt stops and slippery surfaces. Stopping abruptly, especially on
slippery surfaces, can cause the Segway PT's Tires to lose traction, causing
you to fall.

Figure 47: Stopping

72

Step 8: Turning

The Segway PT turns in the direction that you lean the Handlebar. You turn
the PT by leaning the Handlebar left or right.

Turning In Place

First, practice turning in place. To turn in place, slowly pivot the Handlebar
to the side in the direction that you want to turn. The PT will rotate in that
direction, turning in place. Practice turning to the right and to the left using
this technique.

Turning While Moving

After you are comfortable going forward and backward and turning in place,
try slowly riding forward and turning at the same time. Keep your knees
slightly bent and lean in the direction of the turn in coordination with the angle
of the LeanSteer Frame. Keep your body aligned with the LeanSteer Frame
while turning. Because abrupt turns may have unintended consequences,
always lean into turns slowly and smoothly.

Figure 48: Turning In Place

Figure 49: Turning While Moving

73

Step 9: Stepping Off

When you are ready to step off the Segway PT for the first time, your spotter
should hold the Handlebar.

Remain stationary by keeping your weight centered over the Wheels and
Powerbase and keep the Handlebar vertical. To step off the PT:

1. Without leaning backward or to the side, step off the PT, one foot
at a time.

WARNING

Be careful not to pull back or turn the Handlebar while you are stepping off
the Segway PT.

2. After you have stepped off, continue to hold the Handlebar in place.
If you let go, the PT will roll forward and can potentially cause injury
or damage.

3. When you step off, the PT enters Riderless Balance Mode. In
Riderless Balance Mode, the PT moves forward, backward and turns
in response to how you move the Handlebar. Use Riderless Balance
Mode to move the PT over curbs or terrain where it is unsafe or
undesirable to ride.

Figure 51 shows the Balance Indicator lights and the InfoKey Controller
display as you step off the PT.

NOTE:

If you move too fast in Riderless Balance Mode, the PT will give the Stick
Shake Warning and transition to Standby Mode.

74

Step 10: Securing Your Segway PT

The Segway PT provides a Security function in case you need to leave your PT
unattended. The Security function includes an alarm and uses the motors to
make it difficult to move your PT.

The best way to discourage tampering with your PT is to keep it in a secure
indoor location with the InfoKey Controller stored separately. The Security
function is intended for use when you remain in the general area of the PT,
and are able to respond to an alarm. If you must leave your PT unattended in
a location that is not secure, activate the Security function with your InfoKey
Controller and use a lock. To set the Security function:

1. Step off your PT.

2. Press the Security button on the InfoKey Controller.

3. The PT provides an audio indication that the Security function is ac­tivated and a lock icon displays on the InfoKey Controller:

Be sure to take your InfoKey Controller with you (do not leave it with
the PT).

4. To deactivate the Security function, press the Security button on the
InfoKey Controller. The Lock icon on the InfoKey Controller disap­pears and the Security function is no longer activated.

Security button

Figure 52: Securing Your Segway PT

75

Step 11: Powering Off the Segway PT

1. Power off the Segway PT by pressing and holding the Power/Stand­by button on the InfoKey Controller for two seconds.

2. The display on the InfoKey Controller will show a sleepy face and the
PT will emit a tone as it powers off.

Power/Standby button

Figure 53: Powering Off The Segway PT

76

Practice Riding

You will need to become very familiar with your Segway PT before you
attempt to ride outside of your controlled practice environment. The more
you practice, the safer you will be when you move into new places. Remember
the following as you practice:

• Use the Beginner Setting and ride in areas free of obstacles and
distractions until you are comfortable on your PT. Practice at the
Beginner level until you can step on, ride forward and backward,
turn, stop, and step off with the same precision and confidence as
you walk.

• With practice, you should be able to ride in narrow areas. You
should also be able to ride, turn, and stop on a narrow, curving,
paved walkway.

• Until you can ride with this precision, do not attempt to ride in
any area where you might encounter children, pedestrians, pets,
vehicles, bicycles, or other obstacles and potential hazards.

• Your first rides without the Beginner Setting should be in the same
secure areas where you learned to ride with the Beginner Setting.

• Use caution when riding in new environments.

• Be careful when riding through a doorway.

• Make sure you leave enough Wheel clearance.

• Watch out for terrain transitions such as pavement and grass.

Practice Riding (cont.)

Navigating Terrain

With practice, you can learn to ride over many different types of terrain,
provided you avoid slippery surfaces, loose materials, steep slopes, and ob­stacles. Always proceed slowly over unfamiliar terrain. Never allow the PT to
become airborne, even for short periods of time, because the PT has no trac­tion when airborne, and you could lose control upon landing.

Terrain Compensation

The PT is designed to compensate for uneven terrain. When riding straight
on uneven terrain, keep the LeanSteer Frame vertical. Point the LeanSteer
Frame in the direction you want to move and allow the Powerbase to follow
the contour of the ground.

Navigating Stairs and Curbs

WARNING

If the Wheels slip while guiding the Segway PT up or down stairs or curbs, the
PT may exit Riderless Balance Mode and enter Standby Mode. The PT will not
"assist" you in moving up or down the stairs while in Standby Mode. Slowly
and carefully guide your PT down the stairs. Re-enter Riderless Balance Mode
before you try again.

WARNING

Keep the Segway PT below you at all times. Lead it up the stairs, curbs, and
slopes and keep it below you when descending stairs, curbs, and slopes.

Figure 55: Keep the LeanSteer Frame Vertical on Slopes

78

1. Step off of the Mats.

2. Check the Console and verify the PT is in Riderless Balance Mode

(see Table 3, p. 31).

3. Walk around so you are in front of the PT.

4. Carefully guide the PT to the stairs and align the Wheels perpendicu­lar to the stairs or curb.

5. Always stand above the PT, facing the Handlebar. Gently guide the
PT up or down, one step at a time.

Riding Etiquette

User proper etiquette when riding your PT.

• Be careful and considerate of others.

• Always ride under control at a speed that is safe for you and those

around you.

• Always be prepared to stop.

• Respect pedestrians by always yielding the right of way.

• Avoid startling pedestrians. When approaching from behind, an-

nounce yourself and slow down to walking speed when passing. Pass
on the left whenever possible. When approaching a pedestrian from
the front, stay to the right and slow down.

• In heavy pedestrian traffic, slow down and proceed at the pace of
pedestrian traffic. Pass only if there is ample space to do so safely.
Do not weave in and out of pedestrian traffic.

Figure 56: Navigating Stairs and Curbs

continued

79

Riding Etiquette (cont.)

• When riding with other PT riders, maintain a safe distance, identify hazards and obstacles, and do not ride side-by-side unless there is
plenty of room left for pedestrians.

• Do not park your PT in a way that blocks pedestrian traffic.

• Cross roads at designated crosswalks or signaled intersections. Do not jaywalk/ride.

• Only travel on a road when a pedestrian way is not available or when sidewalk use is not allowed. Do not ride your PT on private property

(inside or outside) unless you have obtained permission to do so.

• Learn about and obey applicable laws and regulations.

Riding Tips and Safety Guidelines Recap

The Segway PT's unique balancing ability and ease of use may lead you to become overconfident. If you exceed the ability of the PT to balance,
such as by riding over obstacles, uneven terrain, slippery surfaces, loose materials, or steep slopes, you can very quickly lose control, leading
to collisions, falls, and injury. As with any other transportation device, using a PT exposes you to risk of injury. You can reduce the risk by
following all the instructions and warnings in this Manual, but you cannot eliminate the risk.

• Read this Manual and watch the Safety Video.

• Pre-ride inspection. Inspect your PT before each use (see "Pre-Ride Checklist" on the inside back cover of this manual). Do not use if

any part is loose or damaged. If you discover any loose or damaged part, see "Troubleshooting Procedures" (p. 119).

• Do not place any objects on the Mats. This could cause the PT to move on its own when in Balance Mode, possibly damaging your PT
and rendering it unsafe for use.

• Do not allow any person to use your PT unless that person has carefully read this Manual and watched the Safety Video.

80

• Do not use the PT in hazardous atmospheres. The PT has not been certified for use in hazardous atmospheres as defined in NFPA
70, National Electric Code. Hazardous atmospheres are locations where fire or explosion hazards may exist due to flammable gases,
vapors, liquids, dust, or fibers.

• Wear a helmet. Whenever you ride your PT wear a helmet that fits properly with the chin strap in place. Use
an approved bicycle or skateboard helmet that provides protection for the back of your head. Depending on
riding conditions and your riding experience, consider using additional protective equipment such as gloves, eye
protection, wrist guards, and knee pads. Wear footwear that protects your feet and provides adequate support
and comfort.

• Spot new riders until they are comfortable with the basic operation of the PT. All new riders should
use the Beginner Setting. The safety of new riders is your responsibility. Do not allow anyone to
step onto the PT for the first time unless you are there to hold the Handlebar. Do not let new riders

operate the PT outside of your direct supervision unless they have read this Manual and watched
the Safety Video.

• Avoid slippery surfaces, loose materials, steep slopes, and obstacles. If you cannot avoid a slippery
surface, loose material, steep slope, or obstacle, then you must step off and use Riderless Balance
Mode to move across it. Be especially careful when riding in confined spaces or near obstructions.

• Use caution on slopes. Use caution when ascending, descending, or crossing slopes. Do not attempt
to ride across any slopes with loose material or slippery surfaces. Instead, step off and use Riderless
Balance Mode, walking with the PT held downhill from you. When riding across any slope, lean uphill to
maintain balance.

• Watch those turns! Always turn slowly and with caution. Fast turns can lead to loss of control and falls.
Lean into turns.

• Do not take risks. When you encounter a slope, uneven terrain, or other terrain
feature with which you are not experienced or that makes you at all concerned about your safety, do not
risk riding over it. Instead, step off and use Riderless Balance Mode.

• You are taller than you think. Be aware of the added height that the PT (and your helmet) gives you and
use caution when riding indoors or in the vicinity of doorways, archways, branches, signs, or other low
overhead obstacles.

81

Riding Tips and Safety Guidelines Recap (cont.)

• Do not wear loose clothing that can catch in the Tires and prevent proper steering.

• No passengers. The PT is for one rider. Do not ride double or carry any passengers. Do not carry a child

in your arms or in a child carrier while riding. Expectant mothers should not ride the PT.

• Do not exceed the maximum weight limit (rider and all cargo) specified in this Manual. If you exceed the
maximum weight limit, you are at greater risk of falling and injury, and damage to the PT could result.
Also, the rider's weight must not be less than the minimum rider weight limit specified in this Manual. If
you are below the minimum rider weight limit, you may not be able to ride safely because you cannot shift your weight far enough

back (behind the center line of the Wheels) to safely slow down and stop, especially when riding downhill. Riders
below the minimum weight limit might also fail to properly activate the PT's Rider Detect Sensors. For additional
information on weight limits, see "Operating Limits" (p. 14).

• Never ride on stairs or through revolving doors. Riding on stairs is extremely dangerous, as is riding on
escalators and through revolving doors.

• Do not step off a moving PT. Always come to a stop before stepping off.

• Do not ride in the dark. Do not ride the PT in low visibility conditions without a light. To ride safely, you must be able to clearly see

what is in front of you and you must be clearly visible to others.

• Be alert. As with any other transportation device, you must be mentally alert to safely ride a PT. Do not attempt to ride if you are ill
or if you cannot comply fully with the instructions and warnings in this Manual. Do not ride under the influence of alcohol or drugs.
Avoid distractions. Do not use a mobile phone, listen to headphones, or engage in any other activity that might distract you or
interfere with your ability to monitor your surroundings while riding.

82

• Be prepared to stop. Be especially careful when approaching or crossing intersections, driveways, corners, doorways, and other
areas where you may need to slow down or stop to avoid motor vehicles, bicyclists, or pedestrians.

• When riding, keep both hands on the Handlebar and both feet on the Mats. Be relaxed. Ride in a relaxed
position with your knees and elbows slightly bent and head up. Do not attempt to carry any object in
your hand(s). If you need to carry any object, use a cargo accessory that is recommended by Segway or
a securely attached backpack with both shoulder straps in place.

• Never restart and ride your PT after it has indicated an empty Battery condition or performed a low
Battery Safety Shutdown. The PT may not have enough power to keep you balanced, especially if you demand a lot of power at once.
If you restart and continue riding, you risk falling. Also, you may damage your Batteries, resulting in reduced Battery life and capacity.

• Do not ride backward, except to maneuver a few feet. Instead, turn and ride forward. There is a difference
between maneuvering backward and riding backward, similar to the difference between stepping back and
walking backward. Maneuver backward only when necessary to open a door or back away from an obstacle.
Avoid turning while maneuvering backward.

• Riding on the road. The PT is not intended or recommended for primary use on roads. If you must ride on
the road, or must cross the road, be extremely careful. Ride as far away from traffic as possible. Allow plenty
of time for crossing roads. Remember, the Speed Limiter or an unexpected obstacle could slow your crossing. Check to make sure
that riding on the road is allowed by law.

• Never let go of a balancing PT. Never let go of your PT when in Balance Mode, because the PT will travel
some distance on its own before transitioning to Standby Mode. The PT will not travel very far if you let
go of it when it is stopped. But, if you let go of it when it is moving at any speed, it could travel much
farther, risking injury to others and damage to the PT.

• Carrying cargo. To carry cargo, use a cargo accessory that is recommended by Segway or a securely
attached backpack with both shoulder straps in place. Do not place cargo (or any object) on the Powerbase. The total weight of any
Handlebar payload plus any other attachments hanging from the Handlebar should not exceed 10 lbs. (4.5 kg). Exceeding this limit
interferes with the PT’s balancing ability and could cause the PT to accelerate on its own, risking injury and damage.

83

Riding Tips and Safety Guidelines Recap (cont.)

• Leave a gap! Leave a gap between yourself and the Handlebar. Do not lean over or into the Handlebar.
Leaning over or into the Handlebar dramatically increases the risk of loss of control, collisions, and falls.

• Do not ride the PT if you suffer any impairment to balance.

• The PT has not been designed, tested, or approved as a medical device. You must be able to step on

and off the PT unassisted, which requires physical abilities similar to ascending and descending stairs
without assistance and without holding the handrail.

• Segway recommends that you not allow children to ride your PT unless: (a) you have first learned to ride, so that you understand the
care and skill required to ride safely; (b) the child has read this entire Manual and watched the entire Safety Video; and (c) you are
satisfied that the child has the knowledge, maturity, and physical ability to ride safely without endangering him/herself or others.
As a general rule, Segway recommends that riders be at least 16 years of age. Keep in mind, all Segway PT riders must weigh at least
100 lbs in order to activate the rider detect system.

Report All Incidents

If you or any other user of your PT is involved in an accident, or if your PT performs in a way that you do not intend or in a way that it is not
supposed to, contact Segway Technical Support.

• Battery Safety

Battery Safety

WARNING

• Do not use a Battery if the Battery casing 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 Batteries.

• Keep out of reach of children and pets. Exposure to Battery voltage could result in death or serious injury.

• Unplug or disconnect the PT from AC power before removing or attaching Batteries or performing any service. Never work on any part of

the PT when it is plugged into AC power. You risk serious bodily injury from electric shock as well as damage to the PT.

• The cells within the Batteries contain toxic substances. Do not attempt to open the Batteries. Do not insert any object into the Batteries or
use any device to pry at the Battery casing. If you insert an object into any of the Battery ports or openings you could suffer electric shock,
injury, burns, or cause a fire. Attempting to open the Battery casing will damage the casing and could release toxic and harmful substances,
and will render the pack unusable.

• Observe and follow all safety information on the warning label found on the Batteries.

• Failure to charge the Batteries could result in permanent damage to them. Left unplugged, the Batteries could fully discharge over time,

causing permanent damage.

• Use only charging devices approved by Segway and never attempt to bypass or override their charging protection circuits.

• Do not wash the Segway PT with a power washer or high pressure hose. Avoid getting water into the Charge Port. Always close the Charge

Port Cover after charging. 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. Failure to follow these instructions could expose you to electric shock, injury, burns, or cause a fire.

charging.

86

Charging Your Batteries

In order to maintain the best performance from your Segway PT Batteries, fully charge the Batteries for at least 12 hours once a month, or
once every 12 hours of operation—whichever comes first. Charge your Batteries only when they are within the specified charging temperature
range (see "Battery Specifications," p. 86).

CAUTION

Failure to charge the Batteries could result in damage to the Batteries. Left unplugged, the Batteries could fully discharge over time, causing
permanent damage. Use only charging devices approved by Segway.

Charging times vary depending on the following:

• Amount of charge already stored in the Batteries—The lower the Battery Charge Level is, the longer it will take to complete the charging
process.

• Temperature of the Batteries—Batteries that are too hot or too cold may not charge or may take much longer to charge. Batteries
charge most efficiently when they are close to the center of the recommended charging temperature range. See "Battery Specifica­tions" (p. 86).

• If storage temperature is below 32° F/0° C, do not charge your batteries. Instead, bring them into a warm (above 50° F/10° C) environ­ment for charging. Doing so will ensure optimal battery life and performance.

87

Charging Your Batteries (cont.)

WARNING

Do not insert the Power Cord plug if the Charge Port, Power Cord, or AC Power
outlet is wet.

To charge the Batteries:

1. Put your PT in a clean, dry place, within the recommended charging
temperature range.

2. Open the Charge Port on the back of your PT’s Console (see Figure

57).

3. Verify that the Charge Port, Power Cord, and AC Power outlet are
clean, dry, and free of debris.

4. Plug one end of the Power Cord (provided with your PT) into a
grounded AC outlet (100V–240V; 50Hz–60Hz). The Power Cord
should be properly grounded (see Figure 57).

5. Plug the other end of the Power Cord into the Charge Port.

6. Verify that the two Charge Indicator lights on the Console illuminate
green to confirm the Batteries are charging (see Figure 58). For
more information on the Charge Indicator lights, see "Battery
Charge Indicator Lights," p. 89.

NOTE:
The PT’s charging system automatically prevents overcharging. Plug your PT
into a grounded AC power outlet when it is not in use. If you do not plan to use
it for an extended period of time, visit your PT every month and remove and
reinsert the power cord to ensure the charging system is working properly.

88

Unplugging the Segway PT

When you are ready to use your PT, remove the Power Cord, then close the Charge Port Cover as follows:

1. Disconnect the Power Cord from the Charge Port on the PT.

2. Disconnect the Power Cord from the grounded AC outlet.

3. Store the Power Cord.

4. Close the Charge Port Cover.

CAUTION

Always keep the Charge Port Cover closed, except when you are charging the Segway PT. Closing the Charge Port Cover prevents water, dirt,
dust, and other contaminates from entering the Charge Port and causing damage to your PT.

Battery Charge Indicator Lights

Two Battery Charge Indicator lights on the Console indicate the charge status of the Batteries when the PT is plugged in. The front Battery
Charge Indicator light corresponds to the front Battery and the rear Battery Charge Indicator light corresponds to the rear Battery (see Figure

58). The Battery Charge Indicator lights provide independent information regarding whether each Battery is charging. When the PT is plugged
in and charging, both Battery Charge Indicator lights will be flashing or solid green. If one or both Battery Charge Indicator lights is red or fails
to illuminate, there is a charging problem with the corresponding Battery. For more information, see "Charging Failures" below.

Charging Failures

If a failure is detected during charging, all charging will stop. Depending on the nature of the failure, a solid red Charge Indicator light displays
or the Charge Indicator light will be off. If either or both Charge Indicator lights are red or off, check the following:

1. If the Charge Indicator lights are off, check that AC power is present, and ensure the Power Cord is fully seated in the Charge Port.

2. If AC power is present and the Charge Indicator lights are either red or off, unplug the power cord, then remove and reseat the
Batteries. For instructions, see "Remove the Batteries" (p. 106) and "Install the Batteries" (p. 22).

3. If these actions fail to resolve the problem, contact an Authorized Segway Dealer or Distributor.

89

Regenerative Braking

The Segway PT has a regenerative braking system that charges the Batteries when descending a hill or slowing down. When you ride down a
hill, you may notice an increase in the Battery charge level. If your Batteries are already completely full at the top of a hill, when you descend,
you may feel the Speed Limiter engage to keep the PT from overcharging its Batteries. For more information on the Speed Limiter, see "Safety
Shutdown" (p. 57).

Reading the Battery Charge Level Display

The horizontal bars on the left side of the InfoKey Controller display indicate the levels of the charge in the PT Batteries. Figure 59 shows how
the PT Battery Gauge on the InfoKey Controller changes as the Battery is depleted.

Full Charge Low Charge

Figure 59: InfoKey Controller Display with Battery Charge Being Depleted

The more charge the Batteries contain, the more horizontal bars are shown. If the Battery charge level is very low, the PT will notify you of a
pending empty Battery condition prior to initiating Safety Shutdown. For more information, see "Safety Shutdown" (p. 57).Do not ride your
PT if there is inadequate charge in the Batteries (indicated by the unhappy face icon on the InfoKey Controller and no dark horizontal lines on
the Battery Charge display). Carefully monitor your PT Battery Gauge and be prepared to step off if your Battery charge becomes completely
depleted.

90

SurfaceCharge(PartialCharge)

Whenever you do not fully charge the PT’s Batteries, surface charge or partial charge may affect the accuracy of the Battery charge level display,
causing it to show a higher charge level than actually exists.

After you power on, check the Battery charge level display and then ride for at least three or four minutes and check the Battery charge level
display again. If the Battery charge level display shows rapid charge depletion during this time, the Batteries have received only a surface charge.
If necessary, plug the PT back in and recharge.

91

Recalibrating the Battery Charge Level Display

WARNING

Do not ride your Segway PT to full Battery depletion. To safely discharge
Batteries below the bottom bar, you should leave your PT powered on in
Balance Mode leaning against a wall in a secure location.

CAUTION

To avoid injury, damage, and to deter theft, be sure your Segway PT
discharges in a safe, secure location, powered on in Riderless Balance Mode.

The PT shows the Battery charge level in the InfoKey Controller, as described
in "Reading the Battery Charge Level Display" (p. 90). The display may be

inaccurate after long periods of storage, or during initial use.

To recalibrate the display:

1. Fully charge the Batteries for 12 hours.

2. Discharge the Batteries (through normal use of the PT) until the
bottom bar in the Display is blinking, representing approximately 10
percent Battery charge remaining (see Figure60).

3. Leave your PT in a safe, secure location, powered on, until the Bat­tery charge is fully depleted, and your PT powers down.

NOTE:

Depleting your PT Batteries from the bottom bar to empty could
take several hours.

4. Fully recharge the Batteries for a minimum of 12 hours, after which
the Battery Charge Level Display will be recalibrated.

92

How Temperature Affects Performance

The Batteries are usually significantly warmer than the air temperature due to
heating that occurs as electricity is delivered from them (while riding) and to
them (while charging).

Riding in Hot or Cold Temperatures

The Batteries will run at the highest efficiency when you operate them near­est the center of the recommended operating temperature range. As with all
batteries, less energy is available at low battery temperatures. You may not
be able to travel the same distance when the Batteries are cold as when the
Batteries are nearer to room temperature.

If the batteries on your Segway PT become too hot or too cold while riding,
the PT may activate a safety alert (see "Safety Alerts," p. 51). If you get a
safety alert soon after you begin riding in cold weather (below 32° F/0° C),
try warming your PT up by bringing it into a warm environment for at least 30
minutes. Table 12 shows the InfoKey Controller icons that display when your
PT Batteries become too hot or too cold.

Charging in Hot or Cold Temperatures

Your Batteries should be within the recommended charging temperature
range prior to and during charging. For the recommended Battery charging
temperature range, see "Temperature Ranges" (p. 86).

The Batteries will charge most efficiently when they are nearest the center of
the recommended charging temperature range. If your Batteries are too hot
or too cold, they may take longer to charge, or they may not charge at all.

If you are concerned that the Batteries may be too cold or overheated during
charging, see "Charging Failures" (p. 89).

93

Replacing Batteries

Your Segway PT is powered by two rechargeable Li-ion Batteries. With normal usage and proper maintenance, Batteries should last the
equivalent of 600 to 1000 full charges. As your Batteries near the end of their useful life, they need more frequent charging and your PT’s
range will be reduced. To order replacement Batteries, contact an Authorized Segway Dealer or Distributor.

Replacing Batteries in Pairs

Whenever you need to replace a Battery, consider replacing both Batteries, and always use pairs of Batteries with the same chemistry.
Replacing only one Battery will not necessarily increase the performance or range of your PT, because the PT is designed to operate only
at the level allowed by the lower-energy Battery. Redundancy is a critical safety feature built into the PT that also applies to the Batteries.
Therefore, you should replace Batteries in pairs (except for the unusual situation where a Battery is replaced because of damage or defect
and the other Battery is relatively new).

For information on removing and attaching Batteries, see "Remove the Batteries" (p. 106) and "Install the Batteries" (p. 22).

94

Battery Transportation, Shipping, and Disposal

If you are transporting your Segway PT, protect the Batteries to avoid damage. Do not expose the Batteries to direct heat or moisture, and avoid
heavy vibration during transportation.

WARNING

Do not use or transport a Battery if the casing breaks open, leaks any substance, becomes excessively hot, or if you detect an unusual odor.
Do not handle a damaged or leaking Battery unless you are wearing disposable rubber gloves, eye protection, and are in a well-ventilated area.
Dispose of the rubber gloves and damaged Battery properly in accordance with regulations governing disposal of toxic materials.

Shipping Li-ion Batteries

Li-ion Batteries are regulated as "Hazardous Materials" by the U.S. Department of Transportation. For information on shipping Li-ion Batteries,
contact the U.S. Department of Transportation at www.phmsa.dot.gov/hazmat/regs or call 1-800-467-4922.

If you need to arrange air shipment of your Segway PT and/or Li-ion Batteries, contact an authorized Segway Dealer or Distributor for assistance.

You must comply with all local, federal, and individual country laws when transporting Segway PT Li-ion Batteries.

Battery Disposal

The Li-ion Batteries used in the Segway PT can be recycled. Recycle or dispose of Batteries in accordance with local environmental regulations.
Do no place in fire or incinerate. For more information, contact Segway at 1-866-4SEGWAY (1-866-473-4929) or visit our website at
www.segway.com.

Maintaining Your Segway PT

The Segway PT is designed to be virtually maintenance free. Make sure it is clean, all parts are installed and functioning properly, Batteries are
charged, and Tires are properly inflated prior to riding. Never open the Console, Powerbase, or Gearboxes. These are not user-serviceable parts.

This chapter describes:

• General maintenance procedures related to your PT

• Important operating tips

WARNING

Before you perform any of the following procedures, verify that the Segway PT is powered off and unplugged. It is not safe to perform these
procedures while the Segway PT is powered on or charging.

Lifting Your Segway PT

WARNING

Watch your fingers! Never lift the Segway PT by its Tires, Fenders, or wheels
because your hands or fingers could become caught, resulting in injury.

Use proper techniques to safely lift and load your Segway PT. Segway
recommends that two people work together to lift the PT.

To lift the Segway PT:

1. Make sure the PT is unplugged and powered off.

2. Select firm, non-moving lifting points such as the Powerbase or
lower cargo frames if equipped.

3. Lift the PT with your legs, not your back (see Figure 61).

Figure 61: Lifting the Segway PT

Lifting the i2 SE Lifting the x2 SE

97

Maintaining Tires and Wheels

WARNING

The tire pressure stated on affixed Wheel labels supersedes any recommended pressure stated on the Tires. Higher pressure reduces suspen­sion performance and traction, and increases risk of loss of control, collisions, and falls. Lower pressure reduces range and increases risk of
damage to the Tire/ Wheel Assembly. Unequal pressure causes the Segway PT to turn in the direction of the lower pressure tire.

To ensure safe and efficient operation of your Segway PT, be sure to check Tires and Wheels regularly, especially if you have recently performed
service on a Tire/Wheel Assembly.

Checking the Tire/Wheel Assembly

To check the Tires and Wheels:

1. Make sure the PT is unplugged and powered off.

2. Check for Wheel wobble by grasping the Tire/Wheel Assembly and attempt to move it side-to-side. The Tire/Wheel Assembly should
not move laterally. If you detect Wheel wobble, check the Wheel nut and tighten if necessary.

For additional information regarding service procedures for the Tire/Wheel Assembly, see "Install the Tire/Wheel Assembly" (p. 109, 111).

TireInationPressure

The Tires on the PT provide suspension and traction. Both functions are affected by tire inflation pressure. Be sure to:

1. Make sure the PT is unplugged and powered off.

2. Check tire inflation pressure regularly (see "Checking Tire Inflation Pressure," p. 107). Improperly inflated Tires will result in less than
optimal range.

3. If tire inflation pressure in either Tire is not at the level stated in the "Segway PT Specifications" (p. 12) for your PT model, inflate the
Tire to the specified pressure.

4. Check that both Tires are inflated equally and are free of debris or contaminates.
