1.  Attach proper mounting bracket to switch housing 
    using screws provided. Tubular spacers are provided 
    for some installations.
2.  Attach appropriate driving lever onto shaft. Do not 
  tighten.
3.  Attach switch and bracket to actuator, making sure 
    that lever is free to rotate over entire range of actuator 
  stroke.
4.  Attach driving pin or bolt through lever arm if slotted, 
    or on driving side of solid lever. (It may be necessary 
    to loosen or remove mounting bracket to accomplish 
    connection on some actuators.)
5.  Operate actuator very slowly and observe movement 
    of all pins and levers to be sure there are no 
    interferences. Slide lever up or down on switch 
    shaft to most desirable position. When all motions 
    are made and clearances are adequate, tighten 
    clamp screw on lever that was left loose in step 2. 
    Tighten all mounting screws. Recheck the travel of all 
    levers and pins for proper clearance through the 
    entire stroke of the actuator.

A.  Operate actuator to full closed position. Set screws 
    hold cams in place on the shaft. For manual cams, 
    grasp cam on knurled segment of cam surface and 
    simply rotate cam to get correct actuation point. Clicks
