When making adjustments to the timer cams, be sure that the first cam next to the timer motor is in its
stop position in the notch. Place one hand over the timer motor with your thumb lodged next to or on the
first cam so that it will not move when the other cams are being adjusted. To make the adjustment, place
your other thumb on the right side of the cam. If a longer operating time is desired. Increase the gap
between the left and right side of the cam. If a shorter operating time Is desired, decrease the gap
between the left and right side of the cam.
