Filling
When filling the sprayer it is necessary to
use an external water source and wear the
appropriate PPE.
The following steps should be followed when
filling the tank:
1. Turn the pump off.
2. Remove the tank lid.
3. Add chemical as required. Some agitation
will take place during the water filling
process after adding the chemical.
4. Use external water source to fill main tank
(Do not exceed the tank capacity).
5. Replace the tank lid and ensure that it is
secure prior to switching on pump. You are
now ready to use the sprayer.
Agitation
Agitation should take place when filling or
through another method as deemed suitable
by the operator.
Spray Application
NOTE : It is the responsibility of the operator
to ensure that the chemical mix is sufficiently
agitated and that the conditions are right
to start spraying. Operators must wear the
appropriate PPE.
1. Remove re-charging plug from the control
panel
2. Check unit for damage and to ensure that
there are no leaks.
3. Remove suction strainer and clean.
4. Replace suction strainer.
5. Follow the filling steps from previous
section.
6. Switch pump ON using ‘On/Off’ switch.
The pump will run until sufficient pressure
is achieved and then the pump will stop.
7. Use the lance by depressing the trigger.
The pump will then automatically maintain
the correct pressure and flow depending
on nozzle adjustment.
8. Adjust the nozzle pattern as required
by rotating the nozzle in the appropriate
direction as required.
9. Use a consistent speed or swath pattern
to ensure even coverage of the target, or
adjust the method of application according
to your target.
NOTE: Ensure that the pump is switched to
OFF when no longer required.
Calibration
All sprayers need to be calibrated and kept
in good condition. This will ensure that the
correct rate of chemical is applied to the
target.
Follow these steps to calibrate the sprayer:
1. Measure the spray width of the nozzle on a
dry surface (in metres).
2. Spray a test area at the intended pressure
and speed. Record distance (in metres)
covered in one minute (minute).
3. Measure the nozzle output in litres over
one minute in a measuring jug (l/min).
The spray volume can be calculated by the
following formula:
Application Nozzle output (l/min) x 10,000
rate (L/Ha)
=
Spray width (m) x speed (m/min)
