13. Check all hoses and fittings for leaks or
damage.
14. Follow the chemical label and ensure that
you follow the specified mixing procedure
for addition of chemicals to main tank.
15. When mixing procedure has been followed,
fill main tank with appropriate quantity of
water required for task at hand.
WARNING:
When filling tanks with water, 1
litre of water will add 1kg of weight. Some
chemicals weigh more than water, therefore
it is the operators responsibility to ensure the
loaded weight of the sprayer does not exceed
the towing and / or carrying capacity of the
vehicle.
16. You are now ready to start using the
sprayer.
Chemical Probe
The optional chemical probe offers a simple
method of transferring chemical into the
sprayer tank. The chemical probe enables
chemical transfer with minimal exposure to
the operator. The probe is used in conjunction
with the Venturi filler (located on the top of the
tank) which creates the required suction on the
pressure side of the pump.
The viscosity of the chemical being transferred
will affect the rate of suction flow and hence
the amount of time required to transfer the
chemical. Water and air have low viscosities
whereas molasses is an example of a highly
viscous liquid. The higher the viscosity of the
liquid, the longer it takes to transfer via the
chemical probe. If the viscosity of a chemical
is such that it takes too long to transfer, dilute
the chemical with water, which will reduce the
viscosity, and then transfer the solution.
The chemical should be transferred after about
20% to 50% of the required water quantity
has been added to the sprayer tank. This will
ensure that agitation takes place when the
remaining water is added.
The end of the probe is not flat so that the
probe, when placed flat against the bottom
of the container, will not restrict the flow of
chemical.
Chemical Probe Operation
WARNING:
It is critical that the chemical probe
venturi continues to operate for a minimum of
30 seconds following use. This will ensure that
no chemical is left in the line prior to the probe
being disconnected.
NOTE:
This item is intended for the induction
of liquid chemicals only.
To operate the chemical probe:
1. Add 20 percent of the tank’s volume of
clean water to the main spray tank. Initially
there needs to be a sufficient amount of
water in the tank in order for the pump
delivery to create the venturi effect via the
venturi filler.
2. Open the Bypass on the controller.
3. To start the pump, engage the PTO at the
lowest revs possible and then gradually
increase revs until the pump reaches its
operating speed. Do not exceed 540 RPM.
4. Ensure that the green handle on the
controller for the Chem Probe is pulled up.
5. Connect probe via cam lever fitting.
6. Open the ball valve above the cam lever
fitting
7. Close all other flip valves and move the
Bypass valve to CLOSED.
8. The pump needs to generate at least 100
psi delivery pressure. Do not run the pump
faster than 540 RPM. The higher the pump
delivery pressure, the greater the venturi
suction and the quicker the probe will
transfer the chemical. The delivery pressure
should not exceed 120 psi as determined
by the pressure relief valve setting.
9. Place probe in chemical.
10. ‘OPEN’ the valve on the probe.
11. The chemical should be now transferring to
the sprayer tank via the venturi filler.
12. When all of the chemical has been
transferred, rinse the chemical container
with water and transfer the rinsate to
the sprayer tank via the probe. This
