Seat stem adjustment

In order to provide fine adjustment of the angle of the seat frame, you will note that the seat stem is fitted with a locknut where the seat stem meets the under seat cross bar. To adjust the seat angle to a position between that normally provided for by the series of holes in the seat stem. To increase the angle turn the stem anti-clock wise, to decrease turn stem clockwise.The holes in the seat must always be aligned so that the locking pin is always free to engage with the desired hole in the seat stem. Once the adjustment has been made and with the knob correctly engaged with the appropriate seat stem hole, the locknut must then be fully retightened.

The adjustment provided by the above means, is intended for adjustment between hole spacings only. The gap between the top of the seat stem and locknut must not exceed 12mm (1/2”) (Fig. 7).

If in doubt consult Sunrise Medical or your local dealer.

Always check to see if the seat stem locking mechanism has properly located into the seat stem hole by exerting downward pressure with your palm on the seat itself.
