• Check the rubber gaiter or boot around the base of the joystick
shaft for damage. Check visually only, do not handle the gaiter.
• Make sure that all components of the control system are securely
mounted.
• Do not overtighten any securing screws.
4.2 Brake Test
These tests should be carried out on a level floor with at least one meter clear
space around the wheelchair.
• Switch on the control system.
• Check the screen remains on after initialization.
• Push the joystick slowly forwards until you hear the parking brakes
operate. The wheelchair may start to move.
• Immediately release the joystick. You must be able to hear each
parking brake operate within 2 seconds.
• Repeat the test a further three times, pushing the joystick slowly
backwards, left and right.
4.3 Drive Test
With the maximum speed control in the minimum position, drive the wheelchair
in all directions, ensuring the drive is comfortable and easy to control for the
user.
Repeat the above but with the speed control set to maximum.
4.4 Gradient Test
Before carrying out this test ensure another person is
present to prevent the wheelchair from tipping
backwards.
Drive the wheelchair forwards up its maximum rated gradient. While on the
gradient release the joystick and ensure the wheelchair comes to rest and the
brakes are applied without the front wheels lifting of the ground.
