1.6. Slopes

It is recommended to avoid using ramps with a slope higher
than 9°. The wheelchair risks tipping over in the event of
spinning or side movement (figure 14).
Upward slopes (figure 15) :
Lean the upper body forward and your centre of gravity will
move forward to a more stable position. Now move the
wheelchair forward with short quick pushes on the hand
rims to maintain speed and direction control. If you want to
rest, apply both brakes when stopping.
Downward slopes (figure 16) :
Lean backward cautiously and your centre of gravity will
8 move backward to a more stable position. Now let the hand
rims slide in your hands. Be ready to react at any moment to
control speed and direction.
Warning : The position of the rear wheel axle and the
angle of your wheelchair's backrest are two of the key adjust-
ments that can affect your stability whilst sat in the wheelchair
(see figure 14A).

greater than 9 degrees and do not attempt to turn
whilst on a slope.The wheel position is usually factory
set and should not be change unless by the direction
of a competent person who must have assessed the
impact of the change on your stability in normal use. If
your wheelchair is fitted with a recliner backrest it is
recommended that anti tippers are also fitted and used
whenever the backrest is reclined from the upright
position.
