Ground Drive Pump Start-Up
4. Check ground drive sprocket setup (page 72).
5. Set rate on pump adjuster dial.
Refer to Figure 3 on page 17 or Figure 4 on page 18
6.
If relief valve has not been previously adjusted,
perform initial setting per page 71.
Prime the Ground Drive System.
7.
Wearing gloves, manually rotate the ground drive
wheel until material appears at the applicator tubes.
Begin field operations.
The pump automatically operates when the implement is
lowered to ground contact and in motion. The pump
automatically stops when the implement is raised for
turns.
Hydraulic Drive Start-Up
Prior to first use, determine the hydraulic remote circuit
flow rate setting per the procedure on page 73.
4. Set console MASTER switch OFF.
5. Set console POWER switch ON.
6. Select FLOW CONTROL RATE1 or RATE2 as
desired, and verify rate setting.
7. Set console BOOMS
a
switch 1 ON.
8. Set the flow rate for the hydraulic remote circuit as
established by the procedure on page 73.
9. Activate the circuit by moving the lever to Retract.
You may hear the pump operating, but with the
MASTER switch off, no material flows to rows.
10. Set the MASTER switch ON. Check for material flow
at the applicators. Prime second hydraulic pump as
required.
11. Begin field operations. Monitor the fertilizer pressure
gauge (or PSI display on optional console).
Field Operations (Either Pump)
12. Monitor the fertilizer manifold pressure (gauge or PSI
display on optional console).
13. Mind the fertilizer tank levels while planting, both to:
a. confirm expected consumption rate, and;
b. avoid running the pump dry.
14. If residual fertilizer is not recovered at end of
planting, apply it to the last field planted.
15. Clean out fertilizer system per page 79.
Pauses and Turns
Ground Drive Pauses and Turns
When the implement is stopped, or lifted, the pump
stops. The boom is still pressurized, but this bleeds down
to 8 psi very quickly (seconds), at which point the nozzle
clamp check valves close off flow to the rows.
Hydraulic Drive Pauses and Turns
If the implement has the optional hydraulic drive system,
pauses cause the speed sensor to report zero speed,
which causes the console to close the flow control valve.
Set the pump hydraulic remote to Float is stopping for
and extended period.
For turns and field moves, set the MASTER switch OFF
to avoid material loss. If the factory configuration of the
plumbing has been modified for section control, use the
BOOM switches as desired for point row applications.
Sharp Object Hazard:
Ground Drive: Exercise caution when near and handling the
ground drive wheel. Wear gloves. The tines may be sharp.
Equipment Damage/Material Misapplication Risks:
Ground Drive: Do not run the pump dry. With all drive chains
in place, the ground drive pump always runs when the
applicator is lowered and in motion. Air rapidly damages the
pump. Keep fluid in pump at all times. Disconnect a chain
when not applying fertilizer.
Hydraulic Drive: Do not run the pump dry. The pump runs
when the remote circuit is active, regardless of applicator
status. Air can damage the pump. Keep fluid in the pump at all
times. Set remote to Float when not applying fertilizer.
If fertilizer is exhausted prematurely, reload fertilizer
immediately. If fertilizer is not available, load clean water,
continue planting with pump operating (to flush system), and
disconnect pump drive before water is exhausted (to keep
pump wet).

a. The factory configuration uses only Valve 1. If the plumbing system has been modified after delivery, it may be necessary to also
engage BOOMS switches 2 or 3.
