Procedure:
1. Raise the litter, Fowler and Knee Gatch to the full up position. Remove the mattress and unplug the power
cord from the wall socket. Properly ground yourself (see page 11).
2. Lift the foot section and pivot it back, securing it with string or cord. Using a 5/32” Allen wrench, remove
the four screws and the two Knee Gatch guides from the sides of the motor/board cover. Using a standard
screwdriver, remove the two sheet metal screws holding the cover to the foot end frame tube and remove
the cover.
3. Disconnect the black cable connecting the Fowler motor to the logic circuit board.
4. Remove and save the small black cap from the end of the quick drop release cable. With two 7/16” open
end wrenches, loosen the nuts on the cable retainer until the end of the quick drop release cable will slide
out. Using a 5/64” Allen wrench, loosen the set screw (A) securing the cable cover at both ends of the
cable and pull off the cable cover.
5. Using a screwdriver, pry off the ball retainers at each end of the black gas cylinder and remove the gas
cylinder. Using a 5/32” Allen wrench, remove the screws (B) holding the guide spacer (C) on each side
of the Fowler tube (D). Trip the Fowler quick drop lever on the end of the actuator* and at the same
time manually lift the Fowler. Use string or cord to secure the Fowler out of the way.
CAUTION
*Do not use the red quick drop release handle because the Knee Gatch will come down.
6. Using two 1/2” wrenches or sockets, remove the two nuts and bolts from each side of the ”Y” shaped
Fowler bracket at the head end of the stretcher. Hold the Fowler lift motor tube (D) so it does not fall and
damage the storage tray.
7. Using a 7/16” wrench, remove the two inner nuts and bolts fastening the motor to the mounting brackets
inside the enclosure at the foot end of the stretcher. Only the two inner bolts need to be removed.
