Meter Doors
Refer to Figure 29 and Figure 30
Each meter box has two distinct access doors on the
bottom:
• Front: Clean-Out
(for emptying hopper)
• Rear: 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.
Meter Door Opening
Material Loss Risk:
Do not open the (forward) clean-out door until preparations
have been made to capture any material to be re-used. Any
material present will flow immediately, possibly in large
volume, as soon as the door is open.
1. Pull out on a clamp handle just until it is loose.
2. Pull out on the other clamp handle. The door
normally will swing down on its own. If not, pull it
open by hand.
Meter Door Closing
Make sure the clamp handles are out or down (not up),
or it will not be possible to close the door.
1. Use a clean rag to wipe any residual material from
the face of the elastomer seals on the door, and from
the bottom face of the meter box.
2. Swing the door up into closed position.
3. While holding the door closed, swing one clamp
handle up, past vertical.
4. Swing the other clamp handle up past vertical.
5. Inspect the door closure for possible air leaks.
Replace any deformed elastomer seal or damaged
latch clamp.
