SECTION 5
PRE-OPERATION
6. For the initial start-up use low tractor rpm and engage
the PTO. Don’t “drop the clutch”.
7. Check and confirm the fan is running correctly, and only
then, gradually increase rpm until the maximum of 540
PTO rpm is achieved.
Check for full range of functionality through the PTO / rpm
range.
CONFIRM SPRAYING
Having previously confirmed the functionality of the
pressure / spray manifold / controller, now is the time to
run with all systems on.
• With the fan running, set the PTO to the intended
operational speed.
• Turn on the controller and both spray rings. Confirm or
adjust the pressure as required.
• Confirm everything is working correctly.
Note; the additional load of the fan running will require
a different power setting from the tractor compared to the
spray functionality testing.
Confirm the overall spray effectiveness
for the
intended purpose as the best results may require a fan
blade angle adjustment.
Spraying should be done in consultation with the spray
manager / agronomist / someone skilled in the art of
spraying. The best setup might vary significantly from crop
to crop, season to season, etc.
SHUT DOWN
Use the reverse order to shut down.
• Reduce engine power / slow PTO speed
• Turn off spray rings
• Turn off controller
• Disengage PTO
• Disengage fan gearbox (optional)
• Drain the main tank
• To avoid algae build up in the freshwater tanks, it is
recommended these also be drained and refilled just
prior to the next spraying job.
The unit is now ready to go spraying.
