9. Adjust the spraying pressure as
follows with the tractor & sprayer
stationary:
(a) On the Spray Controller, select
the MANUAL mode using the
appropriate key.
(b) Switch on all boom valves, and
switch the controller into the
“RUN” position. Water will now
be flowing out the nozzles.
It is recommended to do this
with the boom open in the
spraying position.
(c) Use the “+” key on the Spray
Controller to fully close the
electric servo valve. This will take
a few seconds.
(d) When the servo is fully closed,
adjust the manual pressure relief
valve as shown to the maximum
working pressure. In the case of
the Pegasus, we recommend the
maximum working pressure be
set at 8 BAR (120 psi).
If the maximum pressure is
above this, damage to your
sprayer may result.
(e) Use the “-” key to reduce the
pressure to your normal spraying
pressure - 2-4 BAR (30-60 psi).
10. Check the tank agitator valve is
open.
11. Visually check that both tank
agitators are working.
12. Turn the Controller Master switch
ON & OFF and check all boom
sections switch off together.
13. Turn fenceline* nozzle ON & OFF
to check it is working correctly (*if
fitted)
14. While water is being pumped
through the boom, check for any
leakages or blockages throughout
the sprayer.
Check all hoses, connections,
valves, filters, boom fittings etc.
Check the nozzles are operating
correctly.
Rectify any problems.
15. With all boom operating, re-check
pressure range by alternating from
“+” to “-” on the Spray Controller
while in MANUAL mode.
Ensure maximum pressure does
not exceed 8 BAR. Minimum
pressure should reach almost
zero.
16. Switch booms ON & OFF several
times, ensuring each section is
operating individually, and that
the non-drip nozzle bodies are
working.
17. On completion of checking the
sprayer, turn controls Off by
placing the master switch and
boom switches in OFF position.
18. Disengage PTO or Hydraulic pump
drive after the Spray Controller is
switched off.
Check the tank agitator valve is open. Adjust the manual pressure relief valve.
The maximum spraying pressure will
vary with different nozzles.
We recommend you re-adjust your
maximum pressure if you change your
nozzle selection.
NOTE
+/- keys and auto/man key. Boom switches on, master switch in hold.
