OPERATION (ALL MODELS)
3.3.1 Applying the Brakes
Activate the four wheel central braking
system by depressing the red pedal at any
of the four corners of the unit (Figure 3-1)
to approximately 45°. All four caster wheels
should then be locked from swiveling and
rotating.
3.3.2 Releasing the Brakes
Release the brakes by depressing the green
pedal at any corner of the unit until the pedal
is in a horizontal position (Figure 3-2). All four
wheels should then rotate and swivel freely.
WARNING: Ensure the brakes are locked
when the patient is not being transported.
3.3.3 Applying the Steering Lock / Fifth
Wheel
From any corner of the stretcher, depress the
green pedal downward into locked position
(Figure 3-3). Push the stretcher forward. Either
one caster at the foot end will lock into non-
swivel mode, or the optional fifth wheel will
lower and apply pressure to the floor, thus
guiding the stretcher along a straight path
with minimal steering effort by the attendant.
WARNING: Floors must be smooth and
level to maintain optimum fifth wheel
steering. Fifth wheel steering functions
can be influenced by floor irregularities
(bumps or dips) greater than
1
/
2
” (13 mm)
across the span of the stretcher.
3.3.4 Releasing the Steering Lock / Fifth
Wheel
Release the steering lock by depressing the
red pedal at any corner of the unit until the
pedal is in a horizontal position (Figure 3-2).
All four casters should then rotate and swivel
freely, and / or the optional fifth wheel will
retract.
