Adjusting the Seat Rollers
After you have installed the gas spring, test the seat. It should not rock from
side to side or from front to back, and it should move smoothly up and down
when you adjust it. If the seat is not stable or cannot be positioned smoothly,
you will need to adjust the seat rollers.
Note: You will need assistance to complete this procedure.
To adjust the rollers:
1. Loosen the screws securing the upper front roller. The following figure
shows the location of one of these screws.

2. Have your assistant press the seat pad down until the back roller contacts
the black plastic plate on the back of the frame.
3. Move the upper front roller until it contacts the black plastic plate on the
front of the frame, then tighten the screws again.
4. Have your assistant release the seat pad, then adjust the seat position up
and down a few times. Make sure that the seat moves upward and
downward freely but does not rock or shift in any direction. If the seat
cannot be adjusted easily, or if it continues to rock or shift, repeat this
procedure to readjust the upper front roller.
