1. Remove the patient right side cover. Make sure that the linkages of the manual release that attaches to the side controls
are connected and actuating the manual release valve on the hydraulic pump.
a. If the manual release valve is actuating, then the problem is a faulty velocity fuse. The velocity fuse (6390-001-381)
is located in the cap end cylinder port under the elbow fitting. Remove and replace the velocity fuse.
b. If replacing the velocity fuse does not solve the problem, replace the pressure compensated flow control (6390-001-
151).
c. Replace the hydraulics assembly (6390-001-039).

1. Make sure that the power is on (solid green LED on the trolley control panel).
2. Make sure that the trolley is in the loading position and the latches are engaged.
N No otte e -- The trolley control panel will only work if the trolley is in the loading position and the latches are connected. When
the lifting arms are supporting weight, they only lower to a certain angle. These are safety features.
3. Check the head end indicators (solid green LED) to make sure that the product is in the loading position and that both
latches are engaged.
a. If there is no head end indicator LED activity, then the product is not in the loading position.
b. If the head end indicator LEDs are flashing amber, one or both of the latches are not closed. Check the status of the
latches.
c. If the problem persists, check the switches and connectivity back to the control board.
4. Check connectivity from the trolley control panel back to the control board.
5. Replace the trolley control panel board (6390-001-450).

not excessively worn.
