• Start the Tractor
• Make sure the Fusion controller is NOT in Spray mode
(MASTER is yellow, no green section lights)
• Start the pump by engaging the Tractor remote (Micro
Power Pack version) or PTO. Set to operate at your
required rpm, usually between 450 and 540 rpm.
Higher rpm will give better suction.
• Open (flick UP) the PROBE valve
• Place / hold the probe’s tube into the chemical source
(usually a drum of chemical).
• To suck chemical from the drum to tank, turn on the
probe connection ball valve (circled in
yellow
, shown
in the off position). Use the ball valve to control the
suction. Turn to off when finished.
• Flush with / suck from a clean water source when
finished.
CALCULATE WATER & CHEMICAL
QUANTITIES
Before spraying it is necessary to calculate the exact
quantities of water and chemical needed to spray the
required area of orchard or vines.
For
CHEMICAL required
expressed in litres or kg per
hectare (land area), use the following formula:
Chemicals required (Litres) =
Tank Volume (L) x
Recommended Chemical Rate (L/ha)
Spray Application Rate (L/ha)
eg.
1500 x 5 ÷ 400
= 18.75 litres
For
tank VOLUME OF MIXTURE required
to spray
the selected area,use the following formula:
Tank Volume Required (Litres) =
Area (ha) x Spray Application Rate (L/ha)
eg.
18.75 x 400
= 1500 litres
