Daily checks
Perform the daily check routine before driving:
Checking batteries
• Before using your vehicle for the first time, please charge your batteries for a period of 6 hours.
• Are the batteries sufficiently charged? The green lights on the battery indicator must be on.
Checking remote controller
• 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.
Checking free wheel lever
• Ensure that the free wheel lever has been set to ‘drive’. (Chapter 3.0 of the owner’s manual).
Checking seating
• Ensure that all the cushions are in place.
• Make sure that the backrest is correctly fitted and adjusted.
• Visually inspect the wheelchair to make sure the leg rests, armrests etc. are correctly positioned and attached to the wheelchair
and all fasteners are sufficiently tightened.
Checking clothing on potential entrapment
• When operating the wheelchair, ensure that your clothing does not hamper the wheelchair (i.e. too long). Before use, always
check if your clothing or accessories do not come into contact with the wheels or and other moving and/or rotating parts in which
they could become entangled.
Checking weather conditions
• In winter, batteries have a reduced capacity. During a period of light frost, the capacity is roughly 75% of the normal capacity. At
temperatures below -5˚C this will be roughly 50%. This will reduce your range of action.
Weekly checks
Perform the weekly check routine before driving as described below.

Checking connectors & cables:
• Make sure that all connectors are securely mated.

handle the gaiter.
• Make sure that all components of the control system are securely mounted. Do not over-tighten any securing screws.
• If you are in any doubt about the performance requirements of your wheelchair contact your Sunrise Medical authorized dealer.
• After performing any maintenance or repairs on the wheelchair you must make sure that it is functioning correctly before it is
used.

• When replacing self-locking nuts, or nuts/studs secured with a thread locking solution, ensure that a suitable thread locking
solution is reapplied to the fastener.

• Ensure that any contamination, such as fluff hair , etc is removed from the Velcro straps. Such contamination may affect adhesion.
Monthly checks
