factors that can increase or reduce your range.

English

7

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:

z Rider safety.

z 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 turn 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:

z Higher payloads (weight of rider and all cargo).

z Steeper slopes.

z Bumpier surface conditions.

z Higher speeds.

z Abrupt maneuvers.

8

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.

 Learn to recognize and respond to Safety Alerts; review

“Speed Limiter” on page 48, “Stick Shake Warning” on
page 51, and “Safety Shutdown” on page 55.

Minimum Weight Limit

The rider’s weight must not be less than 100 lbs. (45 kg). If the rider is
below the minimum rider weight limit, 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 limit might fail 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).

English

WARNING!

Exceeding this Handlebar Cargo limit interferes with the
Segway PT’s balancing ability and could cause the Segway PT
to accelerate forward, risking injury and damage.

9

Structural Weight Limits

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:

z Skill level of the rider.

z Payload (weight of the rider and all cargo).

z Surface condition (obstacle height, etc.).

CAUTION

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

10

Maximizing Range

Maximum range distances are provided in Table 2 on page 5. The
range of your Segway PT is affected by many variables, including:

z Terrain: Riding on smooth, flat terrain improves range, and riding

on hilly terrain and unpaved surfaces reduces range.

z Speed and Riding Style: Riding at a consistent, moderate

speed will increase range while frequent starting, stopping,
acceleration, and deceleration reduces range.

z Tire Inflation Pressure: Riding with tire pressures below the

specified limit reduces range.

z Rider Weight and Cargo: Lighter riders with less cargo

experience better range than heavier riders with more cargo.

z 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.

z Battery Condition: Properly charged and maintained Batteries

provide greater range. Old, cold, heavily used, or poorly
maintained Batteries provide less range.

English

z Wind: Riding with a tailwind increases range. Riding against a

headwind reduces range.

Chapter 2:

Getting to Know Your Segway PT

This chapter describes how the Segway PT works. It includes:

z A description of the InfoKey Controller and its buttons and icons.

z Information about Segway PT components.

How the Segway PT Works

The Segway PT works like the human body. When walking, if you
lean forward, you take a step forward to keep your balance. If you
lean back, you step back. On a Segway PT when you lean forward or
back the machine powers the Wheels in the direction that you lean.

The Segway PT uses technology called dynamic stabilization to
maintain its balance and move forward or backward.

English

13

When you lean, your center of gravity moves beyond the contact
patch (the place where the tire contacts the ground) causing the
Segway PT to tilt. The Segway PT’s systems sense this change,
powering the Wheels to keep them underneath you. See Figure 3.

Figure 3. How the Seqway PT Works - Leaning Forward and Back

When you pivot the LeanSteer Frame left, the Segway PT turns left.
When you pivot the LeanSteer Frame right, the Segway PT turns
right. To turn the Segway 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 Segway PT travels
straight ahead. See Figure 4.

14

Figure 4. How Segway PT Works - Turning

The Segway PT’s dynamic stabilization technology balances forward
and backward but not side-to-side. If you tip the Segway 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 Segway 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.

English

English

NOTE:

When riding across a slope with one Wheel higher than the other,
keep the LeanSteer Frame vertical to keep from turning.

15

Segway PT Components and Subsystems

The Segway PT includes the following components and subsystems
(see Figure 5):

z InfoKey™ Controller

z InfoKey Controller Dock

z Handlebar

z LeanSteer Frame

z Tire/Wheel Assembly and Fenders

z Console with Charge and Balance Indicator Lights

z Console Trim

z Mats

z Powerbase

z Batteries

The Segway 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 Segway 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 Segway PT has five redundant
subsystems: Controller Boards, Motors, Batteries, the Balance
Sensor Assembly, and LeanSteer Sensors.

16

WARNING!

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

WARNING!

Do not modify the Segway PT. Modifications to the Segway PT
without the prior written approval of Segway could interfere
with the operation of the Segway PT, could result in serious
injury and/or damage, and could void the Segway PT Limited
Warranty.

Activating the Training Safety Shutdown

Before you demonstrate a Safety Shutdown for training purposes,
you must read about “Safety Shutdown” in the Getting Started
Manual, and watch the Safety Video. The purpose of demonstrating
Safety Shutdown for training purposes is to introduce the rider to the
experience while in a predictable, controlled environment with a
spotter. Read all the following steps prior to activating the Training
Safety Shutdown.

1. Make sure the Segway PT is in Balance Mode.

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

3. The spotter should firmly hold the Segway 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.

32

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 8 shows the InfoKey
Controller display during a training Safety Shutdown.

specified in “Segway PT Specifications” on page 5.

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

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

34

Mats

Your Segway PT comes with two Mats installed to the right and left of
the Console. 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 “Removing/Installing the Mats”

on page 109.

Understanding the Rider Detect Sensors

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

Rider Detect

Sensors

English

English

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

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

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

41

WARNING!

To prevent a riderless Segway 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 Segway PT.

WARNING!

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

42

Controller Boards

Figure 12 shows the location of the Controller Boards.

Figure 12. Location of Controller Boards

The two Controller Boards receive input from the Segway 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 Segway PT will
perform a Safety Shutdown.

 For more information on Safety Shutdown, see “Safety

Shutdown” on page 55.

English

English

43

Motors

Figure 13 shows the location of the Motors.

Figure 13. Location of Motors

Each Wheel is independently driven by redundant, high-speed
electric Motors that are quiet and efficient. Each Motor is computer­controlled to precisely regulate the Segway 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 Segway PT will perform a Safety
Shutdown.

 For more information on Safety Shutdown, see “Safety

Shutdown” on page 55.

44

Balance Sensor Assembly

Figure 14 shows the location of the Balance Sensor Assembly.

Figure 14. Location of 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 Segway PT’s orientation to the
Controller Boards. All sensors are constantly monitored by the
Segway PT to ensure each is operating correctly. If one of these
sensors fail, the Segway PT will perform a Safety Shutdown.

 For more information on Safety Shutdown, see “Safety

Shutdown” on page 55.

English

English

45

Batteries

Figure 15 shows the location of the Batteries.

Figure 15. Location of Batteries

The two 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 Segway PT to operate, both
Batteries must be installed, and both must be Li-ion Batteries. If one
Battery fails or is depleted beyond its safe limit, the Segway PT will
perform a Safety Shutdown.

 For more information on Safety Shutdown, see “Safety

Shutdown” on page 55.

Chapter 3:

Understanding the Safety Alerts

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

z Speed Limiter

z Stick Shake Warning

z Safety Shutdown

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

English

WARNING!

Read and follow all the instructions in the Getting Started
Manual, this Reference 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” in the Getting Started
Manual.

47

Speed Limiter

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

Figure 16).

Figure 16. Speed Limiter

The Segway 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 17. Once you slow to
a speed that the Segway PT determines is safe, it will resume normal
operation and riding position.

48

Figure 17. Gap Between Rider and Handlebar

WARNING!

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

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.

NOTE:

Conditions that may cause the Speed Limiter to activate and show
the face icon with the straight mouth along with the Warning icon,
when you are traveling at less than the maximum speed allowed for
your operating mode include:

z Riding up a steep hill

z Riding on bumpy terrain

English

English

z Riding with fewer than three Rider Detect Sensors

depressed

z The first few seconds after you power on and step on the

Powerbase

z Low Battery charge

z Batteries that are too hot or too cold

z Riding down a hill with fully charged Batteries

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

49

Table 5 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.

50

Stick Shake Warning

One of the ways that the Segway 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 18).

Figure 18. Stick Shake Warning

English

English

51

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. 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:

z You are clear of all obstacles and slopes.

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

 For additional information, see “Safety Shutdown” on

page 55.

When riding, the Stick Shake Warning occurs if you demand too
much power from the Segway PT. The Stick Shake Warning can
happen when riding on a steep slope, rough terrain, or 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 Segway 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 6 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.

within 10 seconds.

53

Rider Off

You do not have to be riding the Segway PT for the Stick Shake
Warning to occur. The Stick Shake Warning occurs if the Segway PT
is moved too quickly while in Riderless Balance Mode. Riderless
Balance Mode is when the Segway 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 Segway PT over a curb or
up stairs.

Table 7 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 7. Stick Shake Warning With No Rider on the Mats

Possible Causes Recommended Action

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

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

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

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

54

Safety Shutdown

If the Segway PT detects a fault in any of its redundant systems or a
Battery is depleted beyond its safe limit, it performs a Safety
Shutdown (see Figure 19).

Figure 19. Safety Shutdown

When a Safety Shutdown occurs, the Segway 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.

English

English

55

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 Segway 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.

56

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 Segway 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 condition persists, contact an
Authorized Segway Dealer or Distributor.

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 Segway PT to perform a
Safety Shutdown. Do not ride within 5 feet (1.5 meters) of any
theft detection system.

The Segway PT’s charging system is automatically controlled to
prevent overcharging. Plug your Segway PT into a grounded AC
power outlet when it is not in use, even if you do not plan to use it
for an extended period of time.

67

Unplugging the Segway PT

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

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

68

Battery Charge Indicator Lights

Two Charge Indicator lights on the Console indicate the charge status
of the Batteries when the Segway PT is plugged in. The front Charge
Indicator light corresponds to the front Battery and the rear Charge
Indicator light corresponds to the rear Battery (see Figure 23).

English

The Charge Indicator lights provide independent information
regarding whether each Battery is charging.

When the Segway PT is plugged in and charging, both Charge
Indicator lights will be flashing or solid green.

If one or both Charge Indicator lights is red or fails to illuminate, there
is a charging problem with the corresponding Battery.

 For more information, see “Charging Failures” on

page 70.

69

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 is off.

If either or both Charge Indicator lights are red or off, check the
following:

1. If the Charge Indicator lights are off (no illumination), check that
AC power is present, and ensure the Power Cord is full 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
Battery Pack(s).

 For instructions, see “Removing the Batteries” on

page 100 and “Reattaching the Batteries” on
page 102.

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

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 Segway PT from overcharging its Batteries.

 For more information on the Speed Limiter, see “Safety

Shutdown” on page 55.

70

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 Segway PT Batteries. Figure
24 shows how the Segway PT Battery Gauge on the InfoKey
Controller changes as the Battery is depleted.

Full Charge Low Charge

Figure 24. 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 Segway PT will
notify you of a pending empty Battery condition prior to initiating
Safety Shutdown.

 For more information, see “Safety Shutdown” on page 55.

English

English

Do not ride your Segway 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 Segway PT Battery Gauge and be prepared to
step off if your Battery charge becomes completely depleted.

71

Surface Charge (Partial Charge)

Whenever you do not fully charge the Segway 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 Segway PT back in and
recharge.

Recalibrating the Display

The Segway PT indicates the Battery charge level in the InfoKey
Controller, as described in “Reading the Battery Charge Level
Display” on page 71.

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 until the bottom bar in the Display is
blinking (approximately 10 percent Battery charge remaining).

The InfoKey Controller will display the following:

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

72

NOTE:

Depleting your Segway PT Batteries from the bottom bar to empty
could take several hours, depending on Battery condition and the
amount of charge remaining.

WARNING!

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

English

English

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.

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

73

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.

If the Batteries on your Segway PT become too hot or too cold while
riding, the Segway PT may activate a safety alert.

 For more information, see “Understanding the Safety

Alerts” on page 47.

74

Table 11 shows the InfoKey Controller icon that displays when your
Segway PT Batteries become too hot or too cold.

.

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.

75

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” on page 63.

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” on
page 70.

76

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
Segway 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 Segway PT, because the Segway
PT is designed to operate only at the level allowed by the lower­energy Battery.

Redundancy is a critical safety feature built into the Segway 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 reseating

Batteries, see “Removing the Batteries” on page
100 and “Reattaching the Batteries” on page 102.

77

Transporting and Shipping Batteries

If you are transporting your Segway PT, protect the Batteries to avoid
damage during shipment. 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.

78

Chapter 5:

Operating and 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:

z General maintenance procedures related to your Segway PT.

z Important operating tips.

English

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 procedure while the Segway PT is powered on
or charging.

81

Lifting Your Segway PT

Use proper techniques to safely lift and load your Segway PT.

Segway recommends that two people work together to lift the
Segway PT. To lift the Segway PT:

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

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

3. Lift the Segway PT with your legs, not your back. See Figure 25.

82

Figure 25. Lifting the 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 between the Tire and the Fender, resulting in
injury.

English

English

83

Maintaining Tires and Wheels

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 Segway 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 “Installing the Tire/Wheel
Assembly” on page 107.

Checking Tire Inflation Pressure

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

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

2. Check tire inflation pressure regularly. 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” on page 5 for your
Segway PT model, inflate the Tire to the specified pressure.

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

84

WARNING!

The tire pressure stated on any affixed Wheel label (near the
inflation valve) 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.

English

English

85

Cleaning Your Segway PT

To clean your Segway PT:

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

2. Always close the Charge Port Cover after charging, and prior to
cleaning.

3. Gently clean your Segway PT with soap and water and a soft
cloth.

86

Avoid Submerging Your Segway PT

Submerging your Segway PT can cause permanent damage (see

Figure 26).

Figure 26. Avoid Submersion

Observe the following rules regarding submersion and water:

z Do not submerge the Batteries or Powerbase in water.

z Avoid exposure to heavy downpours or extended periods of

heavy rain (when riding, storing, or transporting the Segway PT).

English

English

CAUTION

Do not use a power washer or high pressure hose to clean
your Segway PT. Use of these devices could force water into
components that must stay dry.

Do not allow water to get into the Charge Port.

WARNING!

Do not clean the Mat or Tires with any specialized cleaners.
Use of such products may reduce traction.

87

Storing Your Segway PT

To maximize the performance of your Segway PT Batteries, fully
charge your Batteries for at least 12 hours, once a month, or after
every 12 hours of operation—whichever comes first. Charge your
Batteries only when they are within the specified charging
temperature range.

Store your Segway PT (and its Batteries) indoors, in a place that is
free of moisture, humidity, and temperature extremes. Even if you will
not be using your Segway PT for an extended period of time, you
should leave it plugged into AC power. Otherwise the Batteries could
fully discharge over time, causing permanent damage.

Store your Segway PT within the recommended charging and storage
temperature ranges, as shown in Table 10 on page 63 to preserve
the full performance capabilities of the Segway PT Batteries.

CAUTION

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.
