Lap belt...
The lap belt should be fixed so that the belt sits at an
angle of 45 degrees across the users pelvis. The user
should be upright and be as far back as possible in the
seat when correctly adjusted. The lap belt should not
allow the user to slip down in the seat.

5.0 Tyres and Mounting

Solid rubber tyres are standard.
With pneumatic tyres always make sure that the tyres
have the correct air pressure, as otherwise the
performance of the wheelchair may be affected. If the tyre
pressure is too low, rolling resistance will increase,
requiring more effort to move the chair forward. Low tyre
pressure also has a negative impact on manoeuvrability. If
the tyre pressure is too high, the tyre could burst. The
correct pressure for a given tyre is printed on the surface
of the tyre itself.
Tyres are mounted the same way as an ordinary bicycle
tyre. Before installing a new inner tube, you should always
make sure that the base of the rim and the interior of the
tyre are free of foreign objects. Check the pressure after
mounting or repairing a tyre. It is critical to your safety and
to the wheelchair's performance that regulation air
pressure be maintained and that tyres be in good
condition.

6.0 Maintenance and care

• Check the tyre pressure every 4 weeks. Check all tyres
for wear and damage.
• Check the brakes approximately every 4 weeks to make
sure that they are working properly and are easy to use.
• Change tyres as you would an ordinary bicycle tyre.
• All of the joints that are critical to using your wheelchair
safely are self-locking nuts. Please check every three
months to make sure that all bolts are secure (see the
section on torque). Safety nuts should only be used once
and should be replaced after use.
• Please use only mild household cleansers when your
wheelchair is dirty. Use only soap and water when
cleaning the seat upholstery.
