PEDAL LINKAGE ADJUSTMENT – DUAL END CONTROL BASE
Required Tools:
7/16 Open End Wrench
1/2 Open End Wrench
(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 pedals should be level with each other and there should be approximately 4 inches between
the floor and the bottom of the pedal. To raise the pedal height, use a 1/2 open end wrench to loosen the
hex jam nut (E). Using your hand, turn the screw (D) into the bracket. To lower the pedal height, loosen
the screw. Tighten the hex jam nut (E) after the correct height is achieved.
4. Once the pedals are level, the release rod can be adjusted. Using a 7/16 wrench, turn nut (B) clockwise
to shorten the release length and counterclockwise to increase the length.
5. Depress the pedal and be sure the jack descent is triggered when the pedal is approximately one inch from
the floor. The descent should stop when the pedal is released and the jack height should hold. Repeat
the above procedures for the descent pedal at the other end of the bed.
6. After adjusting each descent pedal individually, depress both pedals at the same time. Both jacks should
start descending when the pedals are approximately one inch from the floor. The foot end should lower
slightly faster than the head end. If it does not, see procedure for adjusting the jack descent rate.
7. Remove the wooden blocks supporting the base hood and secure the hood to the base frame.
