The device speed can be controlled by the tilting degree of movement of the joystick. In the beginning, ensure to operate the joystick gently and drive slowly.

Climbing Over a Step

When climbing over a step, approach at a right angle to the step.

Tilting a little = slow

Tilting more = fast

Stop when the front wheels bump into the step.
Slow down after the front wheels have climbed over the step.
Do the same for the rear wheels to get the device over the step.

4. Releasing the Brakes

Certain situations may require control of the device without powering on and using the joystick – known as freewheel mode. This can be accomplished using the two red brake release levers.

Turn off the device power. Push down both of the two brake release levers below the seat.

Raise both brake release levers to re-engage the brakes afterwards.
