then turn on the water supply. When filling is
complete, shut off the supply, disconnect the
hose, replace the bottom fill cap and close the
catches.
Starting the Sprayer
Before starting the sprayer for the first
time ensure the pre-delivery checks have
been carried out
.
When starting the sprayer for the first time,
conduct a trial run using water to become familiar
with the operation of the controls and to check
that all systems are functioning correctly without
any leakage.
When filling the tank, ensure that the basket
strainer is in place and clean. Close the lid
securely after filling.
Before engaging the PTO, the pressure regulator
should be screwed fully out (anti clockwise) to
allow by-pass to the tank and the outlet valves
should be closed, using the individual valve
levers (levers to be horizontal). (Repeat this
procedure each time the pump has been emptied
of liquid i.e. run dry.
Engage the PTO slowly and allow the sprayer to
run in by-pass mode. Once the pump is primed,
increase the PTO speed to 540 rpm.
The pressure can then be regulated by turning
the regulator knob and observing the reading on
the gauge.
The pumps are designed to operate up to a
maximum pressure of 20 bar (290 psi). The
pressure range used for boom spraying will
usually be between 1 and 4 Bar depending upon
the application rate and other factors - refer to the
Calibration section of this manual.
Open the outlet valves that are connected to the
boom or other spraying device to start spraying.
Under most boom spraying conditions, the PTO
speed can be reduced (minimum 400 rpm) and
the pump will still provide sufficient flow to suit the
particular application rate being used. This will
save fuel and unnecessary wear on the tractor
and sprayer components.
Adding Chemicals with the Chemical
Induction Probe (1100L only)
Before adding any chemicals with the induction
probe fill the tank with at least 250 litres of
water. With the tractor PTO running at no less
than 400 PTO rpm turn the outlet valves OFF
and the chemical probe valve (located on control
unit) ON.
Adjust the system pressure using the pressure
regulator to a maximum of 10 Bar to operate
chemical probe. Remove the chemical probe
from the holder located behind the tank.
Insert the chemical induction probe into the
chemical container and open the ball valve at
the top of the probe to start drawing chemical
into the main tank. Continue filling the main tank
with water and keep the pump running to
thoroughly mix the solution.
Shutdown
After using chemicals in the sprayer flush the
tank and pump by running clean water for a few
minutes. If there is a risk of freezing run the
pump dry for 2 to 3 minutes to ensure all liquid is
removed.
Before adding chemicals read and follow
the chemical manufacturer's instructions
and wear the recommended personal
protective clothing.
