Float Level

With air horn and float assembly inverted so that weight of float is on seated needle (air horn gasket must be in place), first check float alignment. Sides of floats must be parallel with sides of air horn. Align floats by bending float lever and remove any excess clearance between float lever arms and air horn lugs by bending float lever arms as necessary. Check measurement from bottom of each float to air horn gasket surface (see Fig 1). If float level not correct (see Specifications), adjust by bending float lever as necessary.

NOTE: If float level measurement made to top of float at free end, see Specifications Table footnote for correct setting.
