Look for the Lift’s serial number on the Invacare sticker located on the mast or base of the Lift:
First 2 digits of the serial number identify the year it was manufactured (10=2010). The next letter (alpha character) is for month (A=Jan. B=Feb C=Mar…..L=Dec).
Model Number should be visible on the manufacture’s label.
RPS350-1 has a manual spreader bar to open/close the base legs.
RPS350-2 has a actuator operated spreader to open/close base legs (uses buttons on hand control).
