4. Operation
Before continuing, ensure you have completely read and understood this manual’s Safety
section, in addition to the safety information in the section(s) below.
4.1. Operation Safety
• Keep away from rotating and moving parts, including the auger flighting, drive components,
shafts, and bearings.
• Do not enter the grain bin while the bin unload is operating.
• Always operate with guards, covers, and shields in place.
• Have another trained person nearby who can shut down the equipment in case of accident.
• Keep the work area clear of bystanders.
• Keep the work area clean and free of debris.
• Ensure maintenance has been performed and is up to date.
Refer to your bin operation manual for specific operating and safety information for your bin.
4.2. Bin Unload Overview
The bin unload system operates by first opening the center sump to remove 70-80% of grain by gravity (see
step 1 below). Next, the intermediate sumps are opened when the center sump runs empty to free the sweep
(see step 2 below). Next, the bin sweep is operated to remove the remaining 20-30% of grain (see step 3 be
-
low). Lastly, the sweep is parked over the sumps for the bin to be refilled again.
Open center hop-
per. Unload until
gravity flow stops.
Open intermediate
hopper and unload
until gravity flow
stops.
Stop equipment
and engage clutch
on bin sweep.
Remove remaining
grain.
Return sweep to
position over inter-
mediate hoppers
and bin is ready to
be refilled.
To prevent serious injury or death from bin collapse,
the center sump must be open first to empty bin.
Make certain there are adequate vents installed on the bin to prevent a vacuum from
forming in the upper portion of the bin during unloading. The pressures on the roof
caused by such a vacuum could damage or cause structural failure to the bin roof.
