What is the Stick Shake Warning?

One of the ways that the Segway HT notifies you that you are at risk of falling is by shaking the Handlebar and making growling noises. This is called 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. Often, the Stick Shake Warning will be short in duration- only occurring for the time that you are exceeding the safety parameters.

Stick Shake Warning is more likely to occur when your Battery Packs are low, cold, heavily used, or poorly maintained.

The Stick Shake Warning can also occur in certain non-riding situations, including moving a Segway HT with no rider on the Platform while in Balance Mode or stepping onto a Segway HT Platform while in Power Assist Mode.

How should I respond to the Stick Shake Warning?

As a general rule, if you feel the Stick Shake Warning while riding, slow down. If the Stick Shake Warning persists, come to a stop and safely step off.

Your specific response will depend on what action you were performing at the time of the Stick Shake Warning. Read through the following list, so you will know how to respond if your Segway HT gives you the Stick Shake Warning:

• Riding aggressively, accelerating or stopping abruptly >> Ease up! Ride more gently, smoothly and slowly.
• Riding against the Handlebar >> Ease up! Leave a gap!
• Riding on rough terrain or steep slopes >> The terrain is too demanding or steep. Ride on smoother, flatter terrain. If you are on a slope, turn perpendicular to the slope, step off, and proceed in Power Assist Mode.
• Riding or pushing against an obstruction >> Stop pushing against the obstruction. Stop, step off, and proceed in Power Assist Mode.
• Riding backward >> Stop, turn in place, and proceed forward.
• During Safety Shutdown >> Come to a controlled stop and safely step off within 10 seconds.
• Moving a Segway HT with no rider on the Platform while in Balance Mode>>When moving your Segway HT in Balance Mode with no rider on the Platform, you must move very slowly, or switch to Power Assist Mode.
• Stepping onto a Segway HT Platform while in Power Assist Mode >> Remove your foot. Level the Platform. Tap the Mode Button to enter Balance Mode. Check the Display for the green smiling face. Move the Handlebar to make sure that the Wheels respond. Try stepping on again.

DON’T try to force your Segway HT to give the Stick Shake Warning while riding. Watch the Video Clip to become familiar with the sound of Stick Shake Warning.

You can experience the Stick Shake Warning without riding, by following the steps below:

• Power on your Segway HT. It will power on in Power Assist Mode.
• Confirm that the Segway is in Power Assist Mode, by checking that the Display shows an orange backlight with no face.
• Tilt the Segway HT toward you significantly, as shown in the picture.
• While keeping the Platform tilted, place one foot on the Platform.
• You will experience the Stick Shake Warning.
• Remove your foot to stop the Stick Shake Warning.

The Stick Shake Warning gives the same vibration in both riding and non-riding situations.
