Manifold Gate Tuning
1. Start with:
 moderate fan speeds (see page 40)

balanced manifold air flow.
2. Begin field operations. Watch for delivery issues
that might be remedied by an uneven flow, such
as blockage, pressure alarms, and seed cracking
or bounce.
3. Adjust fan rpm up and down until you find the
upper and lower rpms that represent the best
working range for each meter. Note the upper
and lower manifold pressures for that operating
range. The ideal pressures for each meter are
likely to be different.
4. If there is no single fan speed that puts both
meters comfortably within ideal operating range,
set the fan to an averaged rpm, and begin
adjusting the manifold fan gate. The goal is to
bring both pressure gauges to levels within the
best range similar to those determined in step 3.
5. After the final gate setting is made, some fan rpm
adjustment may be needed to bring both gauges
to the average readings in the best range.

Hopper Lids
Entrapment and Suffocation Hazard
A hopper that is full, or appears full, can be
an entrapment hazard. You can sink into the
grain and suffocate in a matter of seconds.
Grain bridges and crusts are especially
dangerous.
Never enter a hopper for loading, unloading
or routine maintenance. Keep lid locked
closed or, during storage, locked slightly
open. Store ladder to discourage access to
lid area. Keep children away from drill.
Inhalation Hazards
Hoppers are mildly pressurized and air is
circulating in the hopper when the fan is
running. Opening a lid with the fan running
can expose you to blowing seed, fertilizer
and treatment chemicals. Even with the fan
off, adding seed or fertilizer will create a
dust cloud. To avoid risk of exposure to
hazardous chemicals, turn off fan before
opening hopper lids. Wear eye protection
and dust mask or respirator.
Keep the hopper lids tightly closed for operations.
Open only for material loading, hopper clean-out,
and maintenance. Leave strainer in place except
when instructed to remove it.
Avoid metering problems caused by air leaks:

Check the lid seals frequently for damage.
 Check that the latch tightly closes the lid.

Check hopper pressure reported by the monitor.
Planting Consistency Risk
Air leaks can cause irregular metering of
materials.
Opening Hopper Lid
1. Lift the handle (1).
2. Swing the handle out until the hook (2) releases
from the u - bolt (3).
3. Move the hook clear of the u-bolt and close the
handle.
4. Lift the lid slightly at the pivot end to clear the
strainer (4).
5. Swing the lid away from the strainer. Open only
enough to accomplish the present task.
Each hopper is equipped with a strainer to:

capture large foreign matter in seed and
materials,

prevent entry by animals if lid left open, and;

discourage hopper entry by children.
