Mobile Base Operation
The low boy mobile base is a factory installed option for the 527
and 527W 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 offset 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 offset 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.
LOCKED MODE: When both offset locking bars are in the LOCK position; all (4) casters will not roll or swivel. This
position is used to prevent unwanted movement of the chair.
