Operation
Starting the Sprayer
Before starting the sprayer for the first time
grease all lubrication points including the PTO
shafts. Check that the oil level in the diaphragm
pump is level with the mark in the viewer and if
necessary top up with SAE 20W-50 multigrade
engine oil. Ensure that the gearbox oil level is
correct. Refer Maintenance section for details.
First conduct a trial using clean water only (no
chemicals) to become familiar with the controls
and to check that all systems are functioning
correctly without leakage.
Before filling the tank check that the drain valve
located in front of LH ste
p is in the “pump”’
position, ie. red handle facing forward. Then fill
the tank through the opening after checking that
the basket strainer is in place and clean. Close
and rotate the lid to secure it after filling.
On Supaflo models ensure the shut off valve in
the suction filter is open. It is open when the
yellow cap is turned counter clockwise and closed
when it is pushed in and turned clockwise. It
automatically closes when the cap is screwed off
which allows the filter cover to be unscrewed and
the element to be removed for cleaning while
there is fluid in the tank.
Check that the fan gearbox is engaged and the
required speed is selected. Never engage the
fan drive with the tractor engine running or the
PTO engaged. Moving the gearbox lever to
the high position produces maximum airflow.
The low position produces less airflow and can
be used to protect the crop canopy from
damage. The neutral position enables the
pump to be operated without the fan for hand
spraying or similar operations.
The fan incorporates a centrifugal clutch
which protects the gearbox and driveline if the
PTO is engaged rapidly. The sprayer should
always be operated at 540 PTO rpm to ensure
correct operation of the centrifugal clutch and
to prevent its premature wear.
Flip the required number of spray nozzles to
the open position. Refer to the Calibration
section for information on nozzles and jet
selection.

Before engaging the PTO, and with electric
valve controls, switch the Master valve to the
“Off” position. This places the pump into by-
pass mode and closes the outlet valves to the
spray nozzles on either side of the sprayer.
