Invacare® Ultra Low Maxx by Motion Concepts
WARNING!
Risk of Tipping (Continued)
The power wheelchair may tip over when you
change its stability characteristics by changing
your seating position.
– Consider the backrest being used. For example,
a recessed back can shift your center of gravity
backward and significantly reduce the rearward
stability of the wheelchair. Conversely, a thick
back cushion will shift you forward and reduce
the wheelchairs forward stability.
– Always shift your weight in the direction you
are turning. Shifting weight in the opposite
direction of the turn may compromise stability
of the wheelchair base, causing it to tip over.
– Consider the seat cushion being used. A thick
seat cushion will raise your center of gravity
and reduce the wheelchairs stability in all
directions.
– All Ultra Low Maxx systems are equipped with
drive lockouts. Make certain this is set so as
not to compromise your stability while driving
(refer to 3.3 Safety Lockout and Limit Switches,
page 28).
– The wheelchair has a programmable controller
which allows adjustment of the maximum
acceleration and deceleration of the wheelchair.
Make sure that these are set to an appropriate
level for the system and for you, the user.

WARNING!
Risk of Tipping (Continued)
The power wheelchair may tip over when you
change its stability characteristics by changing
your seating position.
– When operating in reduced speed drive or
anti-tipper lockout, always travel on a smooth
level surface to ensure the wheelchair's stability
is not compromised.
– Ensure all medical conditions are considered
when setting up your wheelchair. Involuntary
muscle movement such as spasms may affect
the stability of the wheelchair, especially when
the seating system is in a tilted or reclined
position.
– When a system is fully tilted or reclined, the
front wheels of the wheelchair should never
come off the ground. If this occurs, please
contact your Invacare provider immediately to
resolve the issue.
