Safety Hook Purpose
The safety hook is designed to prevent the cot from being rolled out of
the ambulance and secure the cot while the operators extend or retract
the legs. After the legs are locked, the cot may be disengaged from the
safety hook.
A correctly-positioned safety hook allows the cot to be loaded into the
ambulance and unloaded from the ambulance without interference,
but will engage the safety bar during every loading and unloading
sequence (Figure 15).
Versions: Ferno offers three safety hooks (Figure 16). Select and install a
safety hook that accommodates your ambulance. If the position of your
safety hook is incorrect, contact Ferno to order a safety hook. See "Ferno
Customer Relations" on page 12.

INSPECTING THE FERNO SAFETY HOOK
WARNING
Failure to install and use a compatible Ferno safety hook
(provided with the cot) can cause injury. Install and use
the cot only with these items.
Improper installation can cause injury. Install the safety
hook so the safety bar will engage the hook during every
loading and unloading sequence.
Modifying the cot can cause injury and damage. Use the
cot only as designed by Ferno.
Important
A properly-positioned, compatible Ferno safety hook must be
used with Ferno cots. Difficulty loading and/or unloading may
result from improperly placed components.
Before installing the safety hook, consult the ambulance
manufacturer for the location of wiring and other elements
under the ambulance floor, and about the ambulance
warranty.
