Procedure:
1. Unplug the power cord from the wall socket. Press fully down on the brake pedal to set the brakes. Pump
the lift pedal and raise the litter fully. Remove the four Phillips screws holding the base hood to the base
frame. Lift and support the base hood using string or bungee cord. Properly ground yourself (see page

2. Disconnect the black and the white wires from the motor cable inside the motor enclosure and clip off the
connectors. Using a 5/32” Allen wrench and a 3/8” wrench, remove the nut and screw holding the green
ground wire to the base tube.

the hole in the enclosure. Remove and save the strain relief. Using a 15/16” wrench, remove the plastic
nut on the connector side of the cord and pull the cord out through the mounting bracket.
4. Remove the plastic nut from the connector side of the new power cord. Thread the new power cord
through the bracket and replace and tighten the plastic nut. Clamp on the strain relief and push it back
into the enclosure.
5. Connect the black and white wires to the motor cable. Reattach the green ground wire.
6. Reattach the base hood using the four Phillips screws. Plug the power cord into a properly grounded wall
