9.10 Adjusting the Tension
Of the Manual Mode Cable
The manual mode cable may occasionally require
adjustment to retain proper function. If the manual mode
activates too quickly or too slowly, adjust the tension
on the cable.
KNOWING WHEN ADJUSTMENT IS NEEDED
•
You
should not
be able to lower the cot without
lifting the yellow retaining lever. If you can, the
cable is too tight. Decrease tension on the cable.
Also, you should be able to pull the red manual
mode handle
1 inch
(Figure 45) before the cot
begins to descend. If the cot begins to descend
earlier, decrease the tension on the cable.
•
If the cot does not lower when the manual mode
handle is pulled, or lowers too slowly, the cable
is too loose. Increase tension on the cable.
ADJUSTING THE CABLE TENSION
1. Place a chock on the lower frame (Figure 46) to
keep the cot from folding and reduce your chance
of injury while working.
2. Locate the two 7/16" adjustment nuts (Figure 47).
Use two 7/16" open-end wrenches to adjust the
nuts. To adjust the tension on the cable, loosen
one nut and then tighten the other nut against it.
•
To increase cable tension:
Loosen the nut nearest
the manual mode handle, then tighten the head-
end nut against it.
•
To decrease cable tension:
Loosen the nut
nearest the head-end of the cot, then tighten the
handle-end nut against it.
3. Remove the chock. Place weight (such as bags of
sand) on the cot and confirm that the manual mode
functions properly. Then return the cot to service.
If the cable cannot be adjusted satisfactorily, replace
the manual cable (see
Parts and Service,
pages 38-39).
Improper adjustment of the manual mode
cable can lead to injury. Adjust the tension
of the manual mode cable when needed.
