4.2

Brake test

These tests should be carried out on an even surface with at least one meter of free space around the
wheelchair.

Switch on the control system.

Check that the screen remains on after start-up. 

Bring the joystick slowly forwards until you hear the parking brakes functioning. In some cases the
wheelchair may begin to move.

Release the joystick immediately. You must hear both parking brakes functioning within 2 seconds.

Repeat the test three times, bringing the joystick slowly backwards, to the left and to the right.

4.3

Test run

Set the highest permitted speed to the lowest value and run the wheelchair in all directions while check-
ing that it runs smoothly and is easy to maneuver.

Repeat the test with the speed control set to the highest possible value.

4.4

Gradient test

Run the wheelchair forwards up its steepest permitted gradient. Release the joystick when the wheel-
chair is on the upward slope and check that the wheelchair stops and that the brakes function as they
should without the front wheels lifting from the ground.

Bring the joystick forwards and continue to run up the slope. Check that the wheelchair moves gently
forwards.

Stop the wheelchair and reverse down the slope. Release the joystick when the wheelchair is on the
upward slope and check that the wheelchair stops and that the brakes function as they should without
the front wheels lifting from the ground.

WARNING

When this test is conducted, an additional person must be present in order to prevent the wheelchair tipping over backwards.
