Weight Limits for Riders and Cargo Dynamic Weight Limits Minimum Weight Limit Structural Weight Limits To keep the Segway HT and rider upright, the Segway HT must always have enough power to be able to turn its wheels forward and backward. Exceeding the weight limits, especially when combined with other variables that require more power (see list below), will increase your risk of falling or damaging the Segway HT.
Maximizing Range Only experienced riders riding in optimum conditions will reach the maximum range distances stated on page 7. The range of your Segway HT is affected by many variables, including: Segway HT specifications > 10 > Terrain: Riding on smooth, flat terrain improves range; riding on hilly terrain and unpaved surfaces reduces range. For example, the Segway GT’s estimated range on a golf course is 8 to 10 miles (13 to 16 km); on pavement, the estimated range is 16 to 24 miles (26 to 39 km).
Model Descriptions i Series The i Series model is optimized for indoor/outdoor use in a wide variety of environments. Weight limits, range and top speed are higher than on the p Series model. The i Series may use either two NiMH Battery Packs or two Li-ion Battery Packs. Older i Series models, originally equipped with NiMH Battery Packs, require a software upgrade to switch to Li-ion Battery Packs. p Series The p Series model is optimized for indoor/outdoor use in densely populated environments.
chapter 1: how the Segway HT works how the Segway HT works Redundant Subsystems 12 The Segway HT works like the human body. If you lean forward, you take a step forward to keep your balance. If you lean back, you step back. Substitute wheels for feet, and you have an empowered pedestrian on a Segway HT. The Segway HT uses technology called dynamic stabilization.
how the Segway HT works > Controller Boards > Motors The two Controller Boards receive input from the gyroscopes and other sensors, and from the Handlebar Electronics. They also monitor battery condition. The Controller Boards send commands to the Motors. The Controller Boards are interchangeable.
how the Segway HT works 14 > Battery Packs > Balance Sensor Assembly > Handlebar Electronics The two Battery Packs are sealed units that require no maintenance besides proper charging and storage. Either Battery Pack can be installed in the front or back of the Platform. Both Battery Packs must be of the same chemistry (for example, you cannot mix one NiMH Battery Pack with one Li-ion Battery Pack). Li-ion Battery Packs are larger than NiMH Battery Packs.
Read and follow all the instructions in the Riders’ Guide and watch the Safety Video for important safety information about Speed Limiter, Stick Shake and Safety Shutdown. When the Segway HT reduces performance, the Display will show the following: Display Icon Speed Limiter The Segway HT will push its Handlebar back to slow the rider down.
Stick Shake Warning how the Segway HT works One of the ways the Segway HT notifies you that 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 will occur if you ride backward too fast or if you demand too much power from the Segway HT, such as by riding on a steep slope, on rough terrain, against an obstacle or by accelerating or decelerating abruptly.
pending empty battery condition even though the Battery Packs were recently charged. Whenever you see the pending empty battery condition icon in the Display, you should come to a controlled stop and safely step off of the Segway HT prior to commencement of the Safety Shutdown.
Rider Detection how the Segway HT works The Segway HT Platform contains four Rider Detect sensors (beneath the Mat), which detect the presence or absence of a rider while the Segway HT is powered on. 18 Mode Button Make sure to press four When a rider (weighing 100 lb./45 kg. or more) is aboard with feet properly positioned on the Platform, all four Rider Detect sensors are depressed, and allow the Segway HT to operate normally in Balance Mode.
chapter 2: helpful hints Before each ride, check to make sure the Tire/Wheel Assembly does not wobble and both Wheel Nuts are tight. Grasp the Tire/Wheel Assembly and attempt to move it side-to-side to check for Wheel wobble. The Tire/Wheel Assembly should not move laterally. If you detect Wheel wobble, check the Wheel Nut and tighten if necessary. See page 40 for additional information regarding service procedures for the Tire/Wheel Assembly.
helpful hints 20 Lifting and Loading Watch Your Fingers Use safe and appropriate loading and lifting techniques. Make sure the Segway HT is powered off prior to lifting. Segway recommends that two people work together to lift the Segway HT. Each person should place one hand on the Control Shaft (below the Height Adjustment Collar). Each person should place the other hand under the Platform or, with the Segway XT, use the Lifting Handles on the Fender Frames. Lift with your legs, not your back.
Using the Parking Stand (i Series only) To deploy the Parking Stand: Reminders: Although your Segway HT is versatile, you should not attempt to tow or push anything with it. If you try to tow a trailer or other item, you may not be able to stop in a safe manner, turn effectively, or handle various terrain features. 1. Make sure the power is off. 2. Tilt the Segway HT back toward you. 3. Turn the lever at the right front corner of the Platform to the left until it is perpendicular to the Fender. 4.
chapter 3: battery packs Safety Guidelines battery packs Follow the instructions in this manual carefully for your own safety, the safety of others, and to maximize battery life and performance. 22 Related Documents The information in this chapter provides a basic understanding of Segway HT Battery Packs. For more advanced information, and for more experienced riders, read the complementary document, “Battery Care Booklet” posted at www.segway.com/support/docs.
Battery Pack Specifications Segway HT Battery Pack Type NiMH- 60 Cell (i Series) NiMH- 48 Cell (p Series) Li-ion - 92 Cell Charging Time Important! 12 hours. As soon as possible and before your first use, charge the Battery Packs for at least 12 hours.
battery packs To Charge Your Battery Packs 24 In order to maintain the best performance from your Segway HT Battery Packs, fully charge your Battery Packs for at least twelve hours, once a month, or once every twelve hours of operation— whichever comes first. Make sure that your Battery Packs are within the specified charging temperature range when charging.
Charging Indicators "R" rear The left charging indicator corresponds to the front Battery Pack, the right to the rear Battery Pack. They are marked “F” and “R,” respectively. The charging indicators provide independent information regarding whether each Battery Pack is charging. Stage Initial Test Fast Charge When a green LED is on, the respective Battery Pack is receiving a pulse of current.
battery packs Charging Failures If a failure is detected during charging, all charging will stop. Depending on the nature of the failure, a solid red charging indicator light will be displayed or the charging indicator will be off. (For Li-ion Battery Packs, the charging indicators will be unlit for approximately 5 minutes after the Cell Balancing stage. See page 25.
In certain situations, such as riding uphill, the battery charge level display may temporarily drop because you are drawing heavily on the Battery Packs. The battery charge level display should return to the actual charge level once you return to level ground and reduce the load on the Battery Packs.
Temperature Affects Performance Charging in Hot or Cold Temperatures The Battery Packs will generally be significantly warmer than the air temperature due to heating that occurs as electricity is delivered from them (while riding) and to them (while charging.) Your Battery Packs should be within the recommended charging temperature range prior to and during charging (see page 23).
Before contacting an Authorized Segway Dealer, you may attempt to troubleshoot certain problems yourself. Refer to the Display Icons on the Handlebar (beginning onpage 32) for information about the operational mode of the Segway HT (Power Assist Mode or Balance Mode), the battery charge level, and fault conditions.
