Important
The head-end casters lock only when the
release handle is released and the trailing part
of each caster orients with the lock pin.

4.6 Head-End Caster Swivel Locks
The stretcher’s head-end casters are locked by default.
In this condition, the wheels can roll (but not swivel)
giving the stretcher greater stability for rolling.
The operator unlocks the casters to allow the wheels to
swivel. This makes the stretcher more maneuverable.
Note: The risk of the stretcher tipping is greater when
the swivel casters are unlocked.
To unlock the casters: At the head end, swing the
release lever to the left and hold it in place (Figure 8).
This unlocks the casters and allows the wheels to swivel
freely. Hold the lever in this position as long as
additional maneuverability is needed.
To lock the casters: Release the release lever and roll
the stretcher toward the head end until the wheels rotate
and lock (Figure 9).
GUIDELINES FOR USE:
The swivel lock release lever is for use only when the
stretcher is in the rolling position (see Position A, page
10). Remember to:
• Lock the casters before loading the stretcher into
an ambulance so the wheels will not swivel and
interfere with loading/unloading.
• Lock the casters before lowering the stretcher. At
a lower position, shifting weight on the stretcher
can cause an unlocked front wheel to swivel
suddenly.
Releasing the swivel locks increases the
possibility for the stretcher to tip. Maintain
control of the stretcher at all times.
