NOTE: Refer to STABILIZER INDENTIFICATION above to determine correct stabilizer assembly.

WARNING

Injury or damage can occur if the height of the stabilizer springs does not correspond to the ap- proximate weight of the user. If the height of the stabilizer springs does not correspond to the ap- proximate weight of the user, the wheelchair will feel less stable and possibly cause the footrests/ legrests to drag the ground.

If adjusting a new cylinder spring, it MUST be com- pressedtothe3-1/2-inchheight(FIGURE12)BEFORE adjusting the stabilizer spring to correspond to the approximate weight of the user. Otherwise the sta- bilizer will not work properly.

NOTE: If the height of the stabilizer springs is less than the height that corresponds to the approximate weight of the user,thewheelchairwillnotbeabletoclear2-inchobstacles.
