Micro Switch Attached to the Frame.

 

This switch signals to the motor control board that the resetting of the Fowler actuator may begin 
because the Fowler is completely lowered, and that the lowering to flat of the Knee Gatch may also 
begin. 

9.  Using a Phillips screwdriver, remove the screw (C) holding the support to the frame. 
10. Remove the cable wires from the micro switch. Note the location of the wires so they will be 

connected correctly to the new micro switch. 

11. Press the switch clips to remove it from the support. 
12. Reverse the above steps to install the new micro switch. 
13. Test the CPR positioning before returning the bed to service.

2.  Fully raise the head section and remove the head board. 
3.  Unplug the bed power cord from the wall outlet. 
4.  Using a 7/16" wrench, remove the nut/sleeve/bolt (D) holding both ends of the activation cable to 

the fixed lever. 

5.  Using a 7/16" wrench, remove the two nuts (E) holding the defective cable jacket to the mobile 

lever. Remove the cable from the lever and recuperate the spring (F). Try as much as possible not 
to move the other cable from its position. 

6.  Unscrew completely the two lock nuts (G) holding the other end of the defective cable to the CPR 

handle. Remove the cable.

Unless otherwise indicated, refer to figure 4.3H on page 38 for the illustration of this procedure 
reference points. 

1.  Fully raise the bed and apply the brakes. Fully raise the head section. 
2.  Unplug the bed power cord from the wall outlet. 
3.  Using two 1/2" wrenches, remove the nut (H) from the bolt holding the lower end of the pneumatic 

cylinder. 

4.  Partially remove the bolt until the lower end of the cylinder is free. Recuperate the shoulder 

spacer/sleeve (I). Disengage the lower end of the cylinder from the remaining sleeve. 

5.  Using an 11/16" wrench, loosen the lock nut (J) and unscrew the cylinder completely from the end 

fitting (K). Note the location of the lock nut before loosening it so the new cylinder will be properly 
screwed into the end fitting. 

6.  Reverse the above steps to install the new cylinder. 

7. 

Test the CPR mechanism for proper operation before returning the bed to service.
