Strainer
Each hopper is equipped with a strainer intended to:
• capture large foreign matter in seed and materials,
• prevent entry by animals if lid left open, and;
• discourage hopper entry by children.
Leave the strainer in place except during strainer and
hopper cleaning.
Check the strainer for residue prior to each loading
operation. Remove, empty and return it to the hopper.
For strainer or hopper cleaning, the strainer lifts out when
the lid is fully open, and bolts are removed.
If the strainer needs to be removed for cleaning, do not
perform these steps until immediately ready to clean the
strainer and return it to the hopper:
• Wear gloves suitable for protection against recent
fertilizers or seed treatments.
• Fully open the hopper lid.
• Remove four restraining bolts.
• Lift the strainer out of the hopper.
• Immediately close and latch the lid (below).
• Clean and dry the strainer.
• Return it to the hopper.
• Re-secure the restraining bolts.
Meter Doors
Refer to Figure 56 and Figure 57 (which depict an earlier
version of the meter without the gate handle extension and
guards - do not operate without guards installed)
Each meter box has two distinct access doors on the
bottom:
•
Under DRIVING Gear: Clean-Out
(for emptying hopper)
•
Under DRIVEN Gear: Calibration
(for meter sampling and meter clean-out)
The doors are closed during transport, loading and
planting. They may be open slightly in storage if the
hopper was not completely dry at clean-out.
The doors need to close and seal tightly during planting.
Periodically inspect the lever clamps
for proper
tension, and inspect the elastomer seals for integrity and resiliency.
