Max. Back Angle Limit
The maximum tilt limit establishes the maximum back angle
for the seating system at tilt/recline combined. The function

of this limit is to prevent the back angle from extending
beyond a maximum pre-set angle. Ultra Low Maxx seating
systems are typically preset at the factory to the maximum
allowable angle and do not require any further adjustment
unless the maximum angle needs to be decreased (see
hazard statement below).
Tilt/Recline:
Max. Tilt/Recline Limit = 168°
Risk of Damage to Wheelchair
– When establishing the maximum back limit,
always consider the size and location of any
personal gear that may be carried on the
wheelchair, as it could cause interference
between the backrest and the wheelchair base
when fully tilted/reclined, and damage the
actuator and/or wheelchair.
