7. Maximum Capacity:
a. The nozzle should be placed into the grain
with the inlet below the surface of the
grain but not below the airslide. It is
recommended that some air be allowed to
enter with the grain to obtain the best
capacity.
b. Open the airslide about 2 inches to start.
Close the airslide until the machine starts
to pulsate. Then open it until the pulsing
stops. This will give a balanced grain and
airflow condition.
c. Watch the amount of grain on the window
in the receiver tank. Keep the window full
yet keep the product moving.
There are several ways to control the
amount of grain on the window:
i.
Decrease the amount of grain entering
nozzle.
ii.
Increase airflow by opening airslide.
iii. Increase airlock speed.
iv. Decrease airlock speed.
The airlock acts as a seal between the
vacuum and pressure sides of the circuit.
Increasing the airlock speed normally will
remove product from the receiver faster.
Refer to Airlock Speed Chart as a guide.
8. Use the regular nozzle until there is
approximately 12 inches of grain left in the bin.
Then switch to the clean-up nozzle to pick up
the last of the grain.
9. When using the clean-up nozzle, it is
recommended that the rubber intake hose be
installed to allow you to move around to pick
up the grain from the corners more easily.
10. Stopping Machine:
a. Remove the intake nozzle from the grain.
b. Allow the unit to run until the grain has
stopped coming out the cyclone.
c.
Stop the airlock.
d. Slow the engine speed down to low idle.
