Ferno Technical Service Bulletin

INSPECTING THE FERNO SAFETY HOOK

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.

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.
