Troubleshooting

Transfer/cot does not move out of the transport position

Transfer/cot does not move out of the transport position when you press the release lever at the foot end of the anchor.

If the lifting arms are over the base tube (powered mode)

1. Press the patient right transfer release lever and the trolley release button at the head end of the anchor at the same time with the help of another person.

2. If the cot is free, then inspect the head end anchor mechanism.

3. If the cot still will not move, then repeat step 1 while simultaneously pulling on the patient right transfer lock trigger at the foot end of the transfer.

Note: This should allow the cot to be pulled out while it is still locked into the trolley and transfer.

4. With the cot pulled out, look at the underside of the transfer. About 15 in. from the foot end, you will see the metal hook with a semi-circle cutout at its head end.

a. Push up on the semi-circle and the cot should be free to move. b. With assistance from another person, pull the cot out.

5. With the cot free, check the foot end anchor mechanism. a. Remove the transfer to inspect the foot end anchor pin. b. Remove the anchor mechanism from the foot end anchor.

If the lifting arms are under the base tube

1. With the help of another person, press the transfer release lever and lift up on one of the cot release handles on the trolley at the same time.

2. If the cot is free, remove the cot and determine whether the black pin will extend up from the anchor head end cover.

Note: The trolley must be in the mid position and the release lever pressed to elevate the pin. a. If the pin extends out without signs of damage, check the casting in the trolley release handle mechanism

(6390-001-328) or the plastic lever in the trolley middle mechanism.

b. If the pin does not extend out, check the head end anchor mechanism for damage.

If the cot still will not move

1. Insert a screwdriver into each notch at the head end of the trolley side covers to release the cot head section latches.

2. After the latches are unlocked, use the release lever at the foot end to release the cot.

3. After the cot is removed, inspect the release handle mechanism in the trolley.

Trolley does not roll smoothly

If rolling is difficult while the trolley is rolling on the transfer

1. Check the rods in the channels on the outside of the transfer extrusion for debris or foreign material and remove, if necessary.

2. 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 trolley.

If rolling is difficult while the transfer is rolling on the anchor

1. Check the metal dead stops (6390-001-246) at the head end of the transfer to make sure that they are fully seated and that they are not rubbing on the anchor extrusion.

2. Check the rods in the channels on the inside of the transfer extrusion. Remove any debris or foreign material.
