Your Power Pedestals
If your seat will not raise up to the proper height, adjust the screw
approximately 1/4 (one-quarter) turn in a counter-clockwise direction and
try the pedestal again.
If your seat will not remain in the upright position, move the adjustment
screw approximately 1/4 (one-quarter) turn in a clockwise direction.
NOTE: You may need to fine-tune your pedestal by moving the
adjustment screw a bit more in one direction or the other.
