Bin Level Installation and Operation
INSTALLATION
Figure 1: 918 and 936 Bin Level - Hanger Hooks and Chains
Double chains are attached to the hopper in three places. One chain from each of the three attachment points is
hooked into a hanger hook to form a “V”. This is necessary to keep the spreader from swinging around the fill-
hole each time the spreader is started.
The Bin Level hanging height can change the spreading pattern. On steep-roofed bins, hanging the Bin Level
lower in the bin will be beneficial for a more level grain spread.
All Bin Levels should be installed so that, during operation, grain from legs or augers is not directly hitting the
mercury switch control plate.
INSTALL THE BIN LEVEL SPREADER AS LEVEL AS POSSIBLE
ADJUSTMENT & OPERATION
Figure 2: Adjusting Flow Rate
The two wing nuts inside of the top of the hopper regulate the volume of grain the Bin Level will spread by
adjusting the gap between the lower end of the hopper and the spreader pan. This adjustment should be
made so the incoming grain operates the switch, turning the motor on at least three times per minute and
not more than six times per minute. If the Bin Level is adjusted to start and stop less than three times per
minute, level spread cannot be achieved. If adjusted to start and stop more than six times per minute, motor
damage can result. Adjusting the Bin Level to operate within the recommended “stop” and “start” pattern is a
must to achieve a level spread.
Figure 3: Outside Ring Adjustment
The outside ring of the Bin Level grain spreader is designed so it can be raised or lowered depending upon the
amount of grain being put through the spreader and the width of spread needed. Because of this feature the
grain is showered up and out into the bin which allows an even spread, regardless of the corn depth in the bin.
To attain this showering action, the outside ring has to be kept higher than the bottom of the hopper cone.
Under normal conditions, the outside ring should be from 1/2” to 3/4” higher than the bottom of the Bin Level
cone or fill hopper.
Raise the ring to throw grain farther to the outside. Lower the ring to decrease spread width.
Figure 4: Side Gate Adjustments
A slide gate is provided in the spreader pan to keep the center level with the remainder of the bin. Adjustment
of the slide gate will vary, depending upon volume and number of start-stops per minute at which the Bin Level
is set.
CHECK PERIODICALLY FOR CLOGGING WITH TRASH
Figure 5: Mercury Switch Control
This is the heart of the Bin Level grain spreader. By use of the mercury switch, the spreader is always operat-
ing under full-load capacity so a very even spread is obtained. IMPORTANT: For proper operation, the
mercury switch plate has to be kept from becoming bent or from having other physical damage, and must
work freely at all times.
Do not direct flow of grain onto the mercury switch plate. Mercury switch and/or motor failure will result!
