Treatment Meter Gate Calibration
(Option)
Perform treatment meter gate calibration seasonally, or
whenever one or more rows appears to be metering at a
rate inconsistent with the dial setting.
Refer to Figure 82
Note: This calibration requires the 403-043V tool
, one
or more of which was supplied with a planter
originally ordered with the treatment hopper option.
If you do not have this tool, you may be able to
substitute a hardened steel rod or length of straight
music wire 1.3 mm (0.051 inches) in diameter, held
vertically.
1. Clean out the treatment hopper, per page 81. Secure
the lid on the hopper, and while the hopper is still
dismounted, invert it on a stable flat surface.
2. Turn the meter knob until the dial reads “ 10 ”.
3. Loosen the two hex head screws that secure the
meter gate ( , not visible in figure, shown in gray).
The gate is a polymer plate with a
∇-shaped opening
under the slotted gate retainer.
4. Insert the small rod end of the tool into the meter
gate opening.
5. Re-adjust the dial to “ 04 ”.
6. Slide the gate into firm contact with the tool rod.
7. Secure the hex head screws .
8. Remove the tool. set the dial to “ 00 ”. Re-install the
hopper on the row.
