The Ultra Low Maxx system is fitted with drive
lockouts. Make sure this is set so as not to
compromise the user's stability while driving.
All power bases have programmable controllers which
allow 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 the user.
Ensure all medical conditions are considered when
setting up the wheelchair. Involuntary muscle
movement such as spasming 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 power base should never come off the
ground. If this occurs, you must adapt the system's
center of gravity.

5.3.1 Adjusting center of gravity

To achieve the best overall base stability, the system depth
should always be adjusted as stated in the service manual.
There are two kits available to fit all seat depths:
Seat depth kit for seat depths 380 – 480 mm
Seat depth kit for seat depths 480 – 580 mm
Tools:
2 x 13 mm wrench
CAUTION!
Risk of strains from lifting heavy parts!
