JACK DESCENT RATE ADJUSTMENT
Required Tools:
Standard Screwdriver
#2 Phillips Screwdriver
Bungee Cords (or equivalent)
Adjustment Procedure:
1. Pump the litter up to full height.
2. Using a #2 Phillips screwdriver, remove the three Phillips screws holding the base hood to the base frame.
3. If the bed is equipped with the 110V outlet option, remove the slotted screw holding the outlet cover. If
the bed does not have the 110V outlet option, remove the two slotted screws holding the cover plate.
4. Use bungee cords or the equivalent to secure the hood up and out of the way.
5. The descent rate needle valve is located on the top of the base of the jack. Turning the needle valve clock-
wise, with a screwdriver, will decrease the rate of descent. Turning it counterclockwise will increase the
rate of descent.
6. Adjust the needle valve so the foot end of the stretcher descends slightly faster than the head end.
NOTE
The larger percentage of a patient’s weight is located in the torso area. Adjust descent rate accordingly.
7. Remove the bungee cords supporting the base hood and secure the hood to the base frame.
NOTE
The jack descent rate was preset at the factory to drop the foot end faster than the head. It is recommended
that the foot drop faster to avoid patient disorientation.
