the hopper gate support member. Position the pin so that the tab prevents the pin from turning Install the cotter
pin into the pivot pin and lock in place. Repeat this for the other side of the gate.
2.
Install the limit switch onto the mount on the hopper gate support member. Connect the wiring to the limit switch.
Test the limit switch lever to determine if it is in the correct position. The lever must click over when the gate is In
the closed position. (The switch is spring loaded and returns to the neutral position when the gate is open. When
contact within the limit switch is made, caused by the movement of the lever, the switch will click.) If this does not
