8 Maintenance
Your Excel G-Evolution wheelchair needs periodical maintenance. This is necessary for long and optimum comfort
for the user of the wheelchair. A badly maintained wheelchair will give more technical problems, turn less flexible
and it won’t be covered by the warranty. Preventive maintenance is very important. We advise you to check, at least
once a year, your wheelchair by a qualified Van Os Medical dealer. This dealer will, where necessary, using only
Excel replacement parts. These annual inspection will make sure your wheelchair will work perfect for years.
There are a lot of things you can do yourself to keep your wheelchair in optimum condition. If you regularly check
the wheelchair and perform (small) maintenance, this will extend the lifetime and increase the ease of use.In the
following paragraphs this little maintenance is further described.
8.1 Tires
You need to check the tires of the wheelchair regularly, because the tires will wear out. If the wear is at an advanced
stage, then you should replace the tires.
8.1.1
Air tires
Air tyres should be checked weekly for correct tyre pressure. You will find the recommended tyre pressure on the
rear wheels and you can check it with a standard car or bicycle tyre pressure gauge. If the tyres of the wheelchair
not have the correct pressure it will lean to the side where the minimum pressure is. It will also influence the driving
comfort and it will mean you have to exert more effort to move the wheelchair.
8.1.2
PU tires
More and more we use PU tyres (polyurethane or puncture-free tyres) on the wheelchair. You can recognise these
tyres because they do not have a valve. These tyres have the advantage that they do not need to be pumped up
and can not be punctured. This PU tyre can just as an air tyre wear out. Check periodically to see if the tread is still
deep enough.
8.2 Brakes
Before you can check the brakes, you need to make sure the tyre pressure is correct, see chapter 7.1.
Inspect both brakes for sharp rims. If there are sharp rims on the brakes we advise you to replace them. Ensure
that all the parts of the brake are in the right position and fastened secure;
Make sure that the mechanism is functioning smoothly. If it is not functioning smoothly put some oil at turning
points with one or two drips of WD40 oil or Teflon. Remove surplus oil and dirt. Also, make sure the brakes do not
come into contact with the wheels as you are moving.
