Is the rail too loose? (If loose, the rail can be rotated or moved
inside the clamp.)

Is the rail clamp positioned properly? The rail clamp must not
○

If adjustment is needed, follow the procedure in "Adjusting the
○
Rail Clamp" below.
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.
