2.4 Operator Height and Strength
The stretcher is designed to minimize the need for lifting. Whenever
possible, use the powered hydraulic system.
A non-powered operation, may require the operators to lift a portion
of the load. Use additional trained help as needed.
Ambulance: When not using power, both operators must lift
●
and hold the weight of the stretcher, patient, and equipment
until the stretcher is held by loading system during the process
to enter the ambulance with no power.
Rolling: Operators/helpers must keep both hands on the main
●
frame, support and balance the load, and maintain control of the
stretcher at all times. Use caution on rough or uneven terrain.
2.5 Using additional help when available
Operating the stretcher requires a minimum of two trained
operators. They may need additional trained helpers when working
with heavy loads (patient plus equipment), or when operating the
stretcher manually.
Two trained operators stand at the loading end and control end
●
of the stretcher, maintain control of the stretcher, operate the
controls, and direct helpers on where to stand and how to hold
the stretcher.
Side helpers may need to walk sideways under some
●
circumstances. Follow local protocols.
Ferno recommends helpers work in pairs to help maintain
●
stretcher balance from side to side

Using Additional Help when Available
Key: O = Operator H = Helper P = Patient
NOTICE
If the ambulance is parked on an uneven surface, the
operators (and any helpers) may need to raise or lower the
legs from the user-set loading height to allow the stretcher to
be loaded into and out of the loading system.
Refer to the chart for suggested placement for operators and helpers.
Supporting Weight: Supporting the weight of the stretcher,
●
patient and equipment requires greater strength from short
operators than from tall operators, because short operators must
raise their arms higher relative to their shoulders.
Manual Override: When using Manual Override to move the
●
stretcher legs, an assistant operator must retract or extend the
stretcher legs. See "Manual Override" on page 26.
WARNING
Untrained helpers can cause injury or be injured. Trained
operators must operate the controls and direct helpers
where to hold the stretcher to avoid pinch points.
