Referring to Figures 4a, 4b and 4c, remove the yellow protective cap to reveal the yellow and
white buttons. Yellow button is for limit switch controlling the lift raised direction and white
button is for retracted direction. The following steps describe how these switches worked.

stop the motor at that point. When a button is in, the limit switch for that direction is disengaged
and the motor is free running. Stopping the motor must be done by pushing the center button on
