Adjusting Tension Of The Actuator Release Handles - Ferno Integrated Patient Transport & Loading System iNX User Manual

Improper adjustment of the actuator-release handle
cables can lead to injury. Adjust the tension of the cables
when needed.
The iN∫X can rapidly descend and cause injury if the
actuator-release handles are activated while you are
adjusting the cable tension. Use caution when adjusting
cable tension.
Improper cable tension can damage the iN∫X. Adjust the
cable for proper function as needed.
Use caution when adjusting the cable tension. Use a
second person (minimum) for assistance.
Do not over-tighten the adjustment nut. Overtightening
can damage the handle assembly. When you have finished
adjusting the tension, snug the nut tight.

6.18 Adjusting Tension Of
The Actuator Release Handles
The cable attached to the control-end and/or loading-end
actuator-release handle may require occasional adjustment
to retain proper function. If the handle activates too quickly
or too slowly, adjust the tension on the cable.

Note: See "Figure 52" on page 44 for the location of the control-
end and loading-end actuator-release handles.
KNOWING WHEN ADJUSTMENT IS NEEDED
If the iN∫X lowers without removing the actuator-release
●
handle from its mount in the backrest or shock frame,
the cable is too tight. Decrease tension on the cable.
If the iN∫X does not lower when the actuator-release
●
handle is fully-compressed, or lowers too slowly, the
cable is too loose. Increase tension on the cable.
ADJUSTING THE CABLE TENSION
Use caution when adjusting the cable tension. Use a second
person (minimum) for assistance.
1. Locate the jam nut (Figure 64) and use a 9/16" or 14
mm open-end wrench to loosen the nut away from the
handle.
2. After loosening the nut, hold the cable steady. (Use
a wrench to hold the cable nut in place if needed.)
Rotate the handle assembly around the cable (Figure
64). As you look at the top of the handle assembly
(where the cable attaches to the assembly):
Rotate the handle assembly clockwise to loosen or
○
decrease the tension of the cable.
○ Rotate the handle assembly counterclockwise to
tighten or increase the tension of the cable.
3. Tighten the jam nut snug-tight. Do not overtighten.
4. Place approximately 150 pounds (68 kg) of weight
(for example, use bags of sand) on the iN∫X patient
surface. Confirm that each actuator-release handle
functions properly. Repeat Step 2 and Step 3 to adjust
the tension of each cable until proper handle function
is achieved.
If the cable cannot be adjusted satisfactorily, contact Ferno
for repair. See "Parts and Service" on page 64.
