2. Blow residual seed to the meters.
3. Clean out the meters with the fan running.
Air Box Clean-Out
Clean-Out Door Damage Risk
Verify clean-out doors are closed before
folding or unfolding the planter to avoid
damage to the doors.
Perform air box clean-out with the fan off.
To perform air box clean-out:
1. Place a tarp or large container under the air box
to catch the seed.
2. If cleaning the air box with seed in the bulk seed
hopper, or to clean out air box because of an
obstruction:
a. Loosen the wing nuts (1) and slide the door
cover up on each side of the air box. Ensure
the slots (2) are uncovered. Tighten wing
nuts.
b. Remove the shut-off gate (3) from storage
position and slide into slots. Secure with
lynch pin.
3. Open the clean-out doors (4) on the bottom of
the air box. Seed in the air box will immediately
fall out of the air box.
4. Tap on the sides of the air box to dislodge any
seed.
5. Close the clean-out doors. Return the shut-off
gate to the storage position and close the door
cover.
6. Perform an air system clean-out to remove any
remaining seed from the air box and all seed in
the meters.
Air System Clean-Out
To perform air system clean-out:
1. Place a tarp or large container under the air box
clean-out to catch seed.
2. Open the air box clean-out doors to empty seed
from the air box.
If there is seed in the bulk hoppers to be emptied,
the shut-off gate can be inserted (see “
Air Box
Clean-Out
”) to control seed flow.
3. Close the air box clean-out doors.
4. Turn on the delivery air fan and let it run.
If most of the meters are shut off, reduce the fan
speed as necessary to obtain a low meter
pressurization.
5. Start at one end of the planter and clean out the
meter. See “ Meter Clean-Out Container ” on
page 62. Use a bucket or the funnel to catch the
seed.
a. Use the meter gate to start and stop seed
flow if using a small container.
b. Close the meter gate.
c. Repeat the procedure for all meters.
6. During air system clean-out, it is common for a
few seeds to dislodge and make their way to
meters already cleaned. To avoid future
problems when the next disk is used, and to
avoid crop mixing, open and close all meter
gates to remove any stray seed.
Air Box Residue Clean-Out
Clean-Out Door Damage Risk
Verify clean-out doors are closed before
folding or unfolding the planter to avoid
damage to the doors.
Flushing the air box with water is not
recommended. If this is done, you will need
to operate the fan for an extended period to
completely remove any moisture before
storing or before field operations.
Planting in extremely dusty conditions, particularly
dusty and humid conditions, can lead to dusty
buildup inside the air box. This residue can cause
seed delivery blockages.
If there is seed in the bulk hoppers, insert the shut-off
gate in the air box (see “ Air Box Clean-Out ”).
Open the clean-out doors and inspect the inside of
the air box. If any areas inside the air box are
