Mobile Base Operation
The mobile base is a factory installed option for the 450 and
450W Model chairs.
The two casters on the patient’s right side and the rear caster
on the patient’s left side of the chair are Total Lock Casters. The
front caster on the patient’s left side is the Steering Caster.
In the FREE or STEER position, the Total Lock Casters will roll and
swivel. In the LOCK position, the Total Lock Casters will not roll or
swivel.
In the STEER position, the Steering Caster will roll but not swivel.
In the FREE position, the Steering Caster will swivel and roll. In
the LOCK position, the Steering Caster will not roll or swivel.
There are three modes for the oset locking bars. See image on
right.
STEERING MODE: When the left-hand locking bar is in the STEER position and the right-hand locking bar is in the
FREE or STEER position; the (3) Total Lock Casters will roll and swivel freely and the (1) Steering Caster will roll but will
not swivel. This mode is used for transport as the Steering Caster acts as a steering wheel to aid in easy transport.
FREE MODE: When both oset locking bars are in the FREE position; all (4) casters will roll and swivel freely. This
position is used when you need to pull the chair away from an object in a perpendicular direction, or turn the chair
with a zero radius.
