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.
On 2000L models before filling the tank check that
the drain valve located in front of LH step is in the
“pump”’ position, i.e. 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.
On 1000L models check the drain valve located
in front of the LH tyre is in the “pump” position, i.e.
with the red handle placed vertically. Fill the tank
through the basket strainer then close and secure
the lid before commencing spraying.
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 putting chemicals into the tank,
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.
With electric valve controls, switch the Master
valve to the “Off” position before engaging the
PTO. This places the pump into by-pass mode
and closes the outlet valves to the spray
nozzles on either side of the sprayer.
Engage the PTO slowly and allow the sprayer to
run in by-pass mode. Once the pump is primed
increase the tractor speed to 540 PTO rpm.
Flip the required number of spray nozzles to the
open position. Refer to the Calibration section for
information on nozzles and jet selection.
