Equipment Damage Risk
Do not run the pump when dry. Remove the
pump drive chain if not applying fertilizer. Air
rapidly corrodes the pump. When not pumping,
fill the pump with clean water or RV antifreeze.
When not applying fertilizer, disengage the chain on
the pump drive.
Tank Loading Preparation
Equipment Damage Risk
Use only materials compatible with polyethylene
and polypropylene. Use only pre - mixed liquid
fertilizer. The system is not designed for dry
fertilizer mixes. Granular fertilizer may damage
the pump and plug orifices.

Wear protective equipment suitable for the material
presently in or previously dispensed from the tanks.

Be familiar with the location of plumbing valves.

Remove the lid on each tank and inspect for left-over
fertilizer not compatible with fertilizer you are adding,
contaminants, debris that might clog filters, trapped
animals, lost tools, etc.

If it is necessary to flush a tank or remove debris too
large to flush, see “” on page 63.

Secure each lid.

At first use each season and after extended use,
check the strainer mounted under the pump. Clean
the strainer before loading fertilizer.

The standard strainer screen size is 80. Some orifice
selections require changing the strainer.

Determine how to monitor the tank fill level. If the day
is bright, or loading at night with a bright light
available, it is possible to see the fluid level through
the tank walls. Otherwise, it is necessary to have an
observer at the tank opening.

Use the proper liquid fertilizer.

Move the planter to level ground.

See the Material Rate manual for rate setting details.
Set the fertilizer drive sprockets and piston pump rate
adjuster according to the rate charts.

Install the recommended size orifice plate at each
active drop line (see Material Rate manual).
Tank Loading Procedure
Use the quick - fill valve to fill the tanks. The quick-fill
valve is located to the left of the fan, behind the left
tank. Material will flow to both tanks when filling.
It is not possible to use the planter pump to
load material, as it only pumps when the
planter is in motion and is only plumbed to
pump to the boom. If the fertilizer source
has no pump, it needs to be elevated above
the tank for gravity fill.
1. Close the quick-fill valve (1).
2. Open each tank valve (2).
3. Close the pump valve (3).
4. Connect the fertilizer supply to the quick-fill valve
inlet (4).
5. Open the supply valve (if any) and check for
leaks.
6. Tell the observer to watch the tank fill level.
The tank lid can be removed to monitor fill
level, but is not necessary. The lid is vented
preventing back-pressure at normal fill and
application rates.
7. Start the source pump (if any).
8. Open the quick-fill valve.
If the ground is not level, one tank may fill faster
than the other. Reduce the inlet rate to allow
them to balance. If one tank becomes full before
the other, close the tank valve to prevent
overflow.
