Filling Tanks
Refer to Figure 52
1.
Connect nurse-tank hose to quick-fill coupler
located at rear tool bar. Lock hose in place with
cam-lock levers.
2. Close valve (not shown) going to the in-line filter
located just before the pump.
3. Open valves at each tank and at quick-fill coupler.
4. Fill tanks, then close valve at quick-fill coupler, and
disconnect the nurse tank hose.
Note: Always close valve at filter when filling or storing
any liquid in tanks. Failure to do so may allow
material to run out of manifold outlets causing
contamination from spillage.
Note: Always fill fertilizer tanks to equal levels. If one tank
fills more quickly, shut that tank valve off to raise the
level in the other tank.
Ground Drive Pump
The liquid fertilizer option uses a ground drive pump
which engages whenever the planter is lowered and in
forward motion. For pump operation and pump
maintenance, refer to the pump manual, supplied in the
liquid fertilizer option package. For fertilizer settings, see
the Seed Rate manual.
System Plugging Risk:
Do not allow fertilizer to remain in the tanks for extended
periods or settling of material and system plugging will occur.
