RIDING YOUR SCOOTER

FAILURE TO FOLLOW ANY OF THE FOLLOWING SAFETY PRECAUTIONS CAN AND MAY LEAD TO DAMAGE TO YOUR DEVICE, VOID YOUR MANUFACTURER’S WARRANTY, LEAD TO PROPERTY DAMAGE, AND CAUSE SERIOUS BODILY INJURY OR DEATH.

Before using your SWFT Gamma, be sure to familiarize yourself with the operating procedures.

OPERATING YOUR scooter

Make sure the SWFT Gamma is fully charged before your initial use.
For charging instructions, please read the section of this manual titled CHARGING YOUR SWFT Gamma.
Stand directly behind your SWFT Gamma and place your left foot on the corresponding foot mat (as shown in the diagram below). Keep your weight on the foot that is still on the ground, otherwise the device may begin to move or vibrate, making it difficult to step on evenly with your other foot. When you are ready, shift your weight to the foot already placed on the SWFT Gamma and step on with your second foot quickly and evenly (as shown in the diagram below). SWFT-GMA-BLK Gamma Foldable Self Balancing Hoverboard Scooter fig

Find your center of gravity. If your weight is distributed correctly on the foot mats and your center of gravity is level, you should be able to stand on your hoverboard as if you were standing on the grund. On average, it takes 3-5 minutes just to become comfortable standing on your hoverboard and maintaining proper balance. Having a spotter will help you feel more secure. The SWFT Gamma is an incredibly intuitive device; it senses even the smallest amount of motion. Having any anxiety or reservation about stepping on may cause you to panic and trigger unwanted acceleration.

When you first begin using your device, the easiest way to get going8 is to focus on your desired direction. You will notice that just thinking about which way you want to go will cause you to shift your center of gravity in that direction. This subtle movement will trigger the SWFT Gamma to begin propelling you in that direction.

The device uses sensors to detect your center of gravity, which determines the direction you will move, how quickly you will accelerate and decelerate, and when you will come to a complete stop. As displayed in the diagram below, tilt your center of gravity in the direction you want to move.
To turn, focus on the direction you wish to turn and stay relaxed. You will notice that as you get comfortable on the device, it becomes easier to maneuver.

REMEMBER:
At higher speeds, it is necessary to shift your weight to overcome inertia and centrifugal force during turns, acceleration and deceleration.
If you encounter bumps or uneven surfaces, bend your knees to keep riding. If you determine that the bumps and surface imperfections are too large to ride over then dismount and carry your hoverboard to a safe operating surface. (Consult the SAFETY CHECKLIST for assistance determining safe riding surfaces)
Dismounting your SWFT Gamma can be one of the easiest steps, but when done incorrectly, can cause you to fall. To property dismount, SWFT-GMA-BLK Gamma
