ESS SC-EB OWNER’S MANUAL
Spraying with your ESS sprayer
Note: When using unfamiliar equipment or chemicals, always test on a
small area before treating the entire crop or surface. Do not use a chemical
with the ESS sprayer if the label prohibits use in low-volume sprayers. This
unit is for light-duty use. Only spray in sessions of 20-30 mintues, with a
5-10 break in between.
Spray Technique
As in spray painting, the goal is to achieve even coverage over the sur-
face. The ESS MaxCharge spray gun is designed to help you do just that
-- by propelling the chemical spray with a gentle air flow, you can stay
well away from the target surface and let the electrostatic attraction do
the rest of the work.
Please note: the spray droplets are very, very fine --- about 40 microns
each. If you are used to working with a conventional sprayer, you may
make the mistake of thinking the target is not wet enough because
you do not see large beads of liquid. In fact, after a pass with the SC-
EB’s MaxCharge spray gun, the surface of the target should just barely
glisten with moisture. The fine droplets will evaporate quickly.
Here are some tips to achieve the best possible coverage with the ESS
SC-EB sprayer.
1. Before each job, ensure that your sprayer is in good
working order (see the pre-spray checklist on page 15 of
this manual).
2. The optimal spraying distance is at least 18 inches away
from the target surface, however 36 to 48 inches may
provide a more even coating. This gives the fine mist
produced by the MaxCharge nozzle room to develop into a
chaotic cloud that will be attracted to the target surface.
3. Hold the spray gun at right angles to the target surface.
Starting at the highest point and using zig-zag horizontal
strokes about 1 meter (3 ft.) wide, spray down to the
lowest point. Try to have each stroke overlap the previous
stroke by about 50%.
4. You can use vertical strokes if it suits the area better. Just
make sure to work in a methodical pattern and let your
strokes overlap.
5. When moving to the next section, allow it to overlap the
previous section by a few inches. Do not leave a gap.
6. The target surface should just barely glisten with the spray.
Do not over-saturate the surface; if you see runs or puddles
it means you are wasting chemicals. Do check to make sure
the newly-sprayed surface is very slightly damp.
7. Be careful to keep the spray gun barrel as level as possible.
If you allow the nozzle to point down too much, it may drip
occasionally.
8. Unlike spray painting, you don’t have to stop the spray on
every return stroke. Just engage the trigger lock and
concentrate on the regular pattern of spraying.
9. Periodically check to make sure the red light is illuminated
on the spray gun.
