JOKER EVOLUTION 34
Carbon fibre footplate
The support tube for the footrest has several pre-drilled holes and the
frame has a further hole allowing the height of the footrest to be
adjusted
(figure 52).
Loosen the two bolts and nuts “B” (figure 52) which are
located under the carbon fibre footrest (using 4 mm Allen key);
this is necessary to keep the same tapering inclination of the
frames. In fact the width of the footplate changes with relation
to its height: the longer the footplate distance the narrower its
width.
Remove bolt and nuts “A” and
“A
1
”
(3 mm Allen key and an 8
mm spanner).
Slide the footrest support tube up or down to the desired
position.
Replace the two bolts and nuts “A” and
“A
1
”
in the nearest
available holes and firmly tighten them.
Finally, tighten the two bolts “B”.
Position of the footplate
The only possible position has the plate facing inward (see figure
52).
In order to avoid hitting objects which could cause the
wheelchair to tip over, we recommend that the
minimum distance between the base of the footrests
and the ground should not be less than 2cm.
After the adjustment, check the front wheel, when
rotating, does not touch the footplate.
With carbon fiber frame do not tighten the bolts “A”
too hard, this may cause serious damage the carbon
fiber.
6.8 Brake adjustment
The parking brake is a very important piece of equipment that
requires careful adjustment to ensure it functions correctly.
The JOKER EVOLUTION wheelchair has been designed so that
the braking system is as simple as possible.
The brake position depends on the rear wheel position (see chapter
6.5 “Rear wheel adjustment”).
Make sure that the bolts are securely tightened.
Check the correct functioning of the brakes by
conducting specific brake tests.
Check that all parts are secure by pushing hard on the
brake lever (while braking). If the brake support should
move or slip during this test, check that the screws
are tightened fully.
