Troubleshooting
Trolley does not roll smoothly (Continued)
3. If rolling is still difficult, check to see if the transfer extrusion is worn around the channels. If so, replace the V-guide
rollers on the anchor.
Trolley rolls part of the way and stops
1. Check the transfer lock bearing in the anchor.
a. Clean the transfer lock pin.
b. Replace the bearing.
c. Apply molybdenum disulfide lubricant (6390-001-263) to the inside of the new bearing.
2. Check the transfer lock override slides (6390-001-261) for excessive wear.
Trolley makes noise while rolling
If the noise occurs when the trolley is rolling on the transfer
When rolling the system out of the transport position, does the trolley get to the foot end of the transfer before the
transfer moves?
1. If no, the transfer lock pin in the anchor, or its return spring, is most likely the problem. The pin should return to the
full up position after it is pressed.
a. Check the transfer lock pin.
b. Clean or replace the spring or bearing as needed.
2. If yes:
a. Remove any debris or foreign objects from the transfer and vehicle floor.
b. Inspect the transfer extrusion for wear.
c. Remove the trolley from the transfer.
d. Make sure that the trolley rollers are free of debris.
3. If this does not solve the problem, or if the transfer extrusions worn around the rods, replace the V-guide rollers on
the trolley.
If the noise occurs when the transfer is rolling on the anchor
1. The noise is likely caused by either the detent roller (usually a high-pitched squeak) or the transfer lock pin (usually
more of a grinding sound).
Trolley LEDs
Trolley LEDs stay off when the trolley reaches the loading position.
1. Confirm that the trolley is powered on and the battery is charged.
2. Make sure that the magnet activator (6390-001-106) is present and that it is fastened at the foot end of the anchor.
3. With the lifting arms down, push on the trolley. Make sure that the system does not roll away from the loading
position and is locked in this position.
4. Remove the transfer. Make sure that the magnet mover trigger (6390-001-205) is intact and undamaged.
5. Remove the magnet mover trigger (6390-001-205).
6. Remove the foot end latch assembly from the transfer and pull out the link in the channel on the patient left side.
a. Check that the magnet nested into that link is present and intact.
