Ag Spray Equipment 6500 Series Sprayer - Manual (Page 7)

FIG. 14
1. Hydraulic pump hoses supplied on the sprayer
include 1 - 1/2” line and 1 - 3/4” line. The 1/2” hose
is the hydraulic supply (in/pressure) and the 3/4”
hose is the return (out/non-pressure).
NOTE: It is recommended for optimal pump performance that
the 3/4” return line connect directly to the tractor hydraulic
reservoir (not tractor SCV port). Doing so eliminates possible
back pressure restriction on the 3/4” return line. Excessive
back pressure restriction can cause hydraulic orbital motor
damage/failure.
2. Proper sprayer pump disengagement. When shutting
off the pump, move the selector to the FLOAT
position to allow the centrifugal pump to come to a
gradual stop. Standard spool valves, which are
found on all tractor hydraulic systems, can cause
potentially damaging high peak pressures in the
hydraulic system when closed, because of abrupt
shutoff of oil flow in both the supply and return lines.
3. Close and lock down the bypass adjusting
screw in the hydraulic motor.
Switch rate controller to manual and press the “+” button on
TeeJet or “Increase” button on Raven, hold for 8 seconds. Then
press the “-” button on TeeJet or “Decrease” button on Raven
for 2 seconds.
Set the tractor hydraulic flow control valve for minimum
hydraulic oil flow to the remote outlet (Tortoise position).
Start the tractor and allow the hydraulic oil to circulate for
approximately 10 to 15 minutes or until adequately warmed.
Prime the centrifugal pump with all valves open.
Open the sprayer control regulating valve and the boom shut-
off valves.
Slowly adjust the tractor hydraulic flow control valve until the
desired boom pressure is attained.
4. NOTE: See manufacture pump operators manual
for further setup and maintenance.

1. Before unfolding boom, remove transport using lock
pins (see figure 1) and tower cylinder transport stop
(see figure 2). Reinstall lock pins and tower stop
before transporting sprayer.
2. Raise tilt cylinders by pushing up on “tilt” toggle
switch to raise boom out of transport saddle.
4. Hold down on outer fold switches to fold-over outer
wings to spray position. Note: Extend the cylinder
completely when extending the outer boom to
eliminate outer wing vibration. To ensure the wing is
locked down hold the toggle switch down for 5
seconds after the boom is fully extended.
(see figure 15)
5. Hold down on “main lift” boom switch to lower boom
to desired spray height. To ensure optimal boom
performance never run boom in fully down position.
Doing so eliminates boom ride accumulator.
6. Reverse the above procedure when converting from
field to transport configuration.
IMPORTANT: Once tower cylinder bottoms out
raise 1”.
WARNING: Outer fold Booms are a vertical fold and once wing
goes past 90° if Air is present in hydraulic system the wing could
gravity free fall causing
possible personal or boom damage.
The sprayers are hydraulically charged at the factory,
but the following procedure should be followed on an annual
basis to prevent possible boom drop, from transport position,
raise “tilt” wings out of transport saddle, swing the “inner” fold
booms 45° out from sprayer frame. Raise “outer” fold wings 80°
from inner wing, lower “outer” fold wings to saddle transport
position. Repeat 3 times. This cycles the hydraulic lines to pre-
vent air pockets in the hydraulic system to prevent “boom drop”.
