Safety Information When Approaching Obstacles; The Correct Way To Approach Obstacles - Invacare AVIVA Storm RX User Manual

Your power wheelchair has been designed to
operate on firm, dry, level surfaces (such as,
interior floors, concrete and asphalt). Other
acceptable surfaces likely to be encountered include
packed soil, grass, and gravel.
Do not operate the wheelchair in any
type or depth of water (edges of
streams, lakes, or oceans.)
If you approach an unfamiliar surface and
feel uneasy about driving on that surface,
avoid that surface.
6.2.2 Safety Information When Approaching
Obstacles
Approach obstacles safely by learning to manage your
wheelchair. Keep in mind your center of gravity to
maintain stability and balance.
While the wheelchair is designed for use primarily in
and around the home, the provider should determine
whether this wheelchair is suitable for the actual
environment in which the wheelchair will be used.
WARNING!
Risk of Injury, Damage or Death
Loss of traction or stability on curbs/obstacles
may cause injury, damage or death.
-DO NOT cross curbs/obstacles that are not
suitable for wheelchairs.
-DO NOT attempt to pass curbs/obstacles
that are greater than the maximum
climbable obstacle height.
-Follow all instructions regarding negotiating
curbs, obstacles and inclines.
Maximum climbable obstacle height is listed in
13 Technical Data, page 56.
CAUTION!
Risk of Injury or Damage
The wheelchair may tip over if obstacles are
not approached correctly.
-Always approach obstacles straight on.
Never approach at an angle, as shown in the
following image.
-Approach obstacles followed by a
gradient with caution. If unsure whether
the gradient is too steep or not, move
away from the obstacle and if possible
try to find another location.
-Put your backrest into an upright position
before ascending an obstacle.

CAUTION!
Risk of Injury or Damage
There is a risk of falling out of the mobility
device if obstacles are not approached
correctly. There is also a risk of damage to
the mobility device, such as broken casters.
-Never approach obstacles that are higher
than the maximum climbable obstacle height.
-Never let the footrest/legrest touch the
ground when descending an obstacle.
-If unsure whether taking an obstacle is
possible or not, move away from the obstacle
and if possible find another location.

6.2.3 The Correct Way to Approach Obstacles

The following instructions for approaching
obstacles also apply to attendants if the
mobility device is equipped with an
attendant control.
Fig. 6-1 Right
Ascending (Going Up) Obstacles
1. Move the backrest into an upright position and
lower the seat to the lowest position using the
powered seating functions, if equipped.
2. Approach the obstacle or the curb slowly, head-on
and at a right angle (or 90°) to the obstacle.
3. Approach slowly and keep at a consistent forward
speed until the rear wheels have also passed over
the obstacle.
Descending (Going Down) Obstacles
The approach to descend an obstacle is the same as to
ascend it, with the difference that you do not need to
stop before descending.
1. Descend the obstacle with medium speed.
Descending an obstacle too slowly
could cause the anti-tippers to get
stuck and lift the drive wheels off the
ground. Driving the mobility device is
then no longer possible.
