PRE-OPERATION
TANK AND EQUIPMENT CLEANING
If a cleaning agent is required (refer to the chemical
label), as is often recommended when changing from one
chemical group to another or as an end of season clean
before storage.
Nufarm’s Tank and Equipment Cleaner is a suitable
cleaning agent. Note this product is available from
Croplands Dealers under part code L-H9704.
Below is a guide procedure, but if in doubt, follow the
instructions provided with the cleaner.
1. First, completely drain the main tank of all liquid.
2. Fill the flush tank. Flush the spray system with water …
run the sprayer as per normal with the tank selection
valve set to FLUSHING tank.
3. Fill the spray tank with freshwater
4. Add cleaning agent into the mixer basket (use
according to instructions)
5. Open the Tank Selection Valve to the MAIN /
spray tank.
• Make sure the area around the fan is clear of
bystanders.
• Make sure the fan is downwind of the operator.
6. Start the tractor
7. Make sure the controller is NOT in spray mode.
8. Start the pump by engaging the Tractor PTO.
Set to “normal” operating rpm
9. Turn ON the controller, both spray lines, and the
agitator. There should also be some flow through the
bypass line (i.e. don’t use low PTO speed).
10. Adjust to normal operating pressures.
11. After sufficient flushing, turn OFF the spray sections.
12. If the cleaning agent is required to soak or stand for a
period, turn OFF the spray lines and completely shut
down the sprayer for the desired period.
13. On completion of flushing, shut down all controls and
disengage the PTO/ hydraulic drive.
14. Open the pull drain valve and allow the cleaning
mixture to drain from the tank
15. Delay the final flushing of the sprayer (again) with
freshwater until just before the sprayer is next used –
that might be in 1 hour or 6 months away if the sprayer
is going into storage for the offseason.
UNHITCHING THE SPRAYER FROM THE
TRACTOR
Locate the sprayer on level ground and apply the brakes
and / or block the wheels so that the Tractor does not roll
when the sprayer is being disconnected.
Disconnect and stow the PTO shaft.
If fitted, disconnect the controller, power lead and signal
loom. Cap the looms connections and stow the control box
in a safe, dry place.
Detach the 3 linkage arms.
