To install, place the pinch arm assembly spring into its bushing. Insert the front end of the
spring into the hole in the pinch arm assembly with the pinch arm 90 degrees from its normal
position. Press the pinch arm assembly back and rotate it to the vertical position. Then slide
the cam bar to the right until the pinch arm assembly is captured in the chassis. The cam bar
must be positioned between the left and right sideplates or the lift mechanism will not work.
