JACK DESCENT RATE ADJUSTMENT
Required Tools:
Screwdriver
(2) Wooden Blocks (10 – 12 inches in length)
Adjustment Procedure:
1. Pump the litter up to full height.
2. Lift the base hood, separating the hood from the base frame. Using the wooden blocks, support the base
hood.
3. The descent rate needle valve is located on the base of the jack. Turning the needle valve clockwise, with
a screwdriver, will decrease the rate of descent. Turning it counterclockwise will increase the rate of de-
scent.
4. Adjust the needle valve so that 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.
5. Remove the wooden blocks 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.
