Ezi-Spot Installation and Instruction Sheet
Operating Instructions
Fill the sprayer with clean water.
Check suction line strainer for dirt or damage.
Connect pump and ensure it primes correctly,
holding the spray lance trigger on until it sprays
steadily.
Check all pipes, hoses, hose clamps and connections
for leaks or damage.
Gun Spraying
When gun spraying ensure the three way tap is
turned to hand gun position, turn on pump. While
gun spraying the pump operates on a pressure
switch. When outlet pressure drops (gun trigger
open) below the preset limit, the switch will close
and the pump operates until the shut-off (gun trigger
closed) high pressure is achieved. Depending on
nozzle setting, cone pattern or straight jet the pump
may cycle on and off, this is normal pressure switch
operation. The shut-off pressure is set to factory
calibrated standards and should not be re-adjusted.
Shutdown and Storage
Check the chemical manufacturer’s label for
disposal of chemical. Drain the excess material
from the tank. Select an appropriate place (one that
will not endanger animals or the environment) for
cleaning and flushing the system.
Flush tank, pump and hose until they flow clean.
This prevents build up of residues in hoses and
pump valves. If heavy frosts are experienced, run
the pump to make sure pump and spray lines are dry.
This will prevent water freezing in the pump or
spray lines and damaging the sprayer.
Boom Spraying
To apply chemical accurately is the key to getting
the job done correctly without under or over
applying, and thus saves you money.
Step one is knowing your real vehicle speed. To
measure your real vehicle speed do the following
Measure a distance of 50 metres using a tape
measure.
Mark these points so they can be clearly seen
when driving past in your vehicle. The starting
point should be far enough so that you are at
spraying speed as you pass the start point.
Time how long it takes in seconds to travel
between the start and finish points.
Divide 180 by the number of seconds it took to
pass between the start and finish points, this last
figure is your speed.
Eg. 180 18 seconds = 10 Your spraying speed
is 10 kmp/h.
Once you know your correct spraying speed you
can look at the nozzle chart.
To read the chart look first along the top to
select your vehicle speed. Eg 10kmp/h
Then come straight down the column below the
selected speed to the volume in litres per hectare
you wish to apply eg. 115 l/ha.
Look to the left of this figure (eg115) till you
are below the column marked “Bar”, you will
see that you need to spray at 2 bar pressure
(30psi).
Look left again and you are looking at a box
with nozzle types (DG, TP, XR etc). For this
example it works out that any of these nozzles
in size ….03 is the correct nozzle to use at this
required rate per hectare at 10 kmp/h.
For normal pasture spraying the nozzle should
be 500mm (1/2 metre) off the ground.
The lower pressuer the better as you will get
less spray drift –2 bar (30psi) is standard
practice.
Remember that 10 % difference in speed means
either under or over applying chemical.
Nozzles should be replaced as routine
maintenance at the end of the spraying season.
For information on spray drift, droplet size, or
specialist spray information please ask your
Bertolini Dealer for a current TeeJet Spray
Products Catalogue. Assistance on how to read
the chart will be given if required. If you don’t
have a Bertolini Dealer close by please call
Bertolini on 07 847 7950 and ask for a
catalogue to be sent out.
Care and Maintenance
Always fill the sprayer from a clean water source.
The line strainer should be checked and cleaned if
necessary each time the tank is filled. Appropriate
protective equipment should be used whenever
maintenance is carried out.
Shutdown and Storage
Check the chemical manufacturer’s label for
disposal of chemical. Drain the excess material
from the tank. Select an appropriate place (one that
will not endanger animals or the environment) for
cleaning and flushing the system. Flush tank, pump
and hose until they flow clean. This prevents build
up of residues in hoses and pump valves. If heavy
frosts are experienced, run the pump to make sure
pump and spray lines are dry. This will prevent
water freezing in the pump or spray lines and
damaging the sprayer.
