Care and maintenance
In order to guarantee a good performance of your equipment, we advise
you to carry out a careful and regular check to your wheelchair.
Do not use abrasive or heigh pressure cleaners on the wheelchair.
Best is to wash it using a damp cloth or a bicycle spray. Dry your
wheelchair thoroughly after a shower or a drive under the rain. Axles
are especially important and should not be left wet. Spread a little
bicycle oil on a cloth and wipe the axle beads, the knob at the end
of the axles and the axles themselves.
CAUTION: sand and sea water damage the ball bearings!
CAUTION: The screws may loosen a little with time. Therefore,
remember to check the tightness of all screws from
time to time. After slackening and tightening the
counternuts several times, renew them to ensure their
full performance.
Tyre repair / change
Dismantle
Before repairing a damaged tyre, remove the wheel from the wheelchair
(see " Using the wheelchair: rear wheel assembly and removal"). Press
the valve until all remains of air are released. Lift one tyre side wall (both
if you are changing the tyre) from the rim, using a bicycle tyre tool. Do
not use a sharp or pointy tool. Then remove the air tube from the tyre.
Mend the air tube using a bicycle repair kit or replace it altogether.
Assembly
Press the interface of the tyre over the rim side. Slightly fill the air tube
with air until it reaches its normal round shape. Slide the valve through
the appropriate hole and insert the air tube inside the tyre. Once the
tube is well inside the tyre without pleats, press the outer side of the tyre
over the rim, starting at the opposite side of the valve and pressing
along the rim until you reach the valve again. Procede the same way on
the other side. Check that the air tube is at no time trapped between the
tyre and the rim and pum-up the tyre to the appropriate pressure (see
"Safety: Tyre pressure).
