Apply grease on the bolt, the spring washer and the inner sides of the bracket, including the
pivot pin, when reassembling the actuator.
11. Reverse the above steps to install the replacement Knee Gatch actuator.
It is of utmost importance
that the Knee Gatch replacement actuator be adjusted prior to
hooking up its tube to the thigh section. An improper adjustment of the actuator can damage the
bed mechanisms.
11.1 Proceed as follow to adjust the new Knee Gatch actuator:
•
Plug the bed. Make sure that the Knee Gatch actuator cable is connected to the PC
Board.
•
Hold firmly the actuator tube and run the Knee Gatch actuator up for a few seconds
then run it down until it stops. This will be the Knee Gatch actuator lower limit.
•
Turn, if needed, the tube in either direction to align the tube holes with the thigh
lever arm holes and insert clevis pin.
12. Test Knee Gatch for proper operation before returning bed to service.
