3. Is the rail clamp properly tightened to secure the rail?

Adjusting the Rail Clamp
1. Load a compatible Ferno cot into the fastening
system.
2. Verify the antler hooks properly engage the loading-
wheel forks of the cot.
3. Verify the rail jaws properly grasp the center of
the fastener post. If not, adjust the rail clamp so it
secures the cot but does not cover the red line on the
adjustment-limit label (Figure 5):
○
Adjust the height of the rail clamp on the mounting
bracket if needed.
○
Adjust the rail clamp side-to-side within the
adjustment range indicated by the adjustment-limit
label (Figure 5). The rail clamp must not cross the
red line on the label.
4. Secure the rail to the bracket. Use a torque wrench
and tighten the rail clamp screws in an X-pattern
to provide even pressure. Set the torque wrench as
follows:
○
180 inch-pounds
OR
○
15 foot-pounds
OR
○
20.337 Newton-meters
Note:
Do not apply oil or lubricant to the screws prior to
tightening.
WARNING
Improper adjustment can cause injury. Stay within the
range between the jaw and the adjustment limit label.
Important
The adjustment limit label ensures the cot will be held near
the reinforcements offered by the bracket. Do not exceed the
adjustment range between the jaw and the label.
