6.13 Adjusting Backrest Control Handles
The cable attached to the backrest control handle (Figure 46) may
require occasional adjustment to retain proper function.
If the backrest lowers without operating the control handle, the cable is
too tight. Decrease cable tension.
If the backrest does not lower when the control handle is used, or lowers
too slowly, the cable is too loose. Increase cable tension.
Follow the same procedure for each control handle.
1.
Loosen the jam nut (NN) with an 11 mm wrench.
2.
Use the 11 mm wrench to hold the jam nut in place (to prevent
it from rotating) , use an 8 mm wrench to adjust the cable nut
(OO) until the control handle functions properly. Viewed from
the top of the backrest, rotate the cable nut counterclockwise
(anticlockwise) to decrease cable tension or clockwise to increase
cable tension.
3.
Confirm that each backrest handle functions properly. Adjust the
tension of each cable until proper handle function is achieved.
4.
Tighten the jam nut.
6.14 Adjusting Position Indicator Lights
To adjust the indicator lights:
1.
Partially-load the cot into the ambulance until the loading-end
safety bar is secure on the safety hook. See "Loading the Cot" on
page 29 and (Figure 47).
2.
Use a 2 mm hex wrench to loosen the set screw (PP) at the side of
the position indicator light (Figure 47 inset).
3.
Use a slotted screwdriver to slightly rotate the light unit inside the
housing. Align both indicator lights to form a straight line on the
ground.
4.
Tighten the set screw.
