2.9 Safety Checks
The electronic circuits in your control system have been designed to be extremely safe
and reliable. The on-board microcomputer carries out safety checks at up to 100 times per
second. To supplement this safety monitoring you should carry out the following periodic
checks.
If the control system fails any of these checks, do not use the wheelchair and contact your
service agent.
2.9.1 Daily Checks
Joystick:
- With the control system switched off, check that the joystick is not
bent or damaged and that it returns to the centre when you push and
release it. If there is a problem do not continue with the safety checks
and contact your service agent.
2.9.2 Weekly Checks
Parking brake:
- This test should be carried out on a level floor with at least one meter
clear space around the wheelchair.
- Switch on the control system.
- Check that the LED remains on, after initialization and that the
battery gauge is displaying a reasonable amount of charge.
- Push the joystick slowly forwards until you hear the parking brakes
operate. The chair may start to move.
- Immediately release the joystick. You must be able to hear each
parking brake operate within a few seconds.
- Repeat the test a further three times, pushing the joystick slowly
backwards,
left
and
right.
Connectors:
- Make sure that all connectors are securely mated.
Cables:
- Check the condition of all cables and connectors for damage.
Joystick gaiter:
- Check the thin rubber gaiter or boot, around the base of the joystick
shaft, for damage or splitting. Check visually only, do not handle the
gaiter.
Mounting:
- Make sure that all the components of the control system are securely
mounted. Do not over tighten any securing screws.
2.9.3 Servicing
To ensure continued satisfactory service, we suggest you have your wheelchair and
control system inspected by your service agent after a period of 1 year from
commencement of service. Contact your service agent for details when the inspection is
due.
