81
Header control switch and/or
auxiliary pump switches on the
pedestal or beside the plumbing
system are not activated.
Engage the header clutch
switch. If the indicator light
beside the auxiliary switch on
the pedestal in the cab is red,
pump is engaged. Depress the
pedestal switch if it is not. Verify
pump is working by checking the
“pump self-prime line”.
30
Pump will not engage.
Sprayer attachment is not hooked
up to the tractor hydraulic and
electrical connectors properly.
Inspect sprayer and tractor
hydraulic and electrical
connections.
27
Not enough hydraulic oil flow to
the spray system pump.
The reel speed dial is not turned
to maximum and the conveyor
speed dial is not turned to 6.
29
Not enough hydraulic oil flow to
the spray system pump.
Increase engine throttle.
29
There is an air lock in the spray
system that cannot be eliminated
by the bleed line to the solution
tank.
Remove a priming plug and
activate pump. Bleed the
system of air and replace the
plug when the pump is primed.
64
Pump is cavitating and there is no
solution flow through the “pump
self-prime line”.
Pump is worn.
Inspect the spray system pump
and seals. Replace pump or
install new parts if necessary.
64
Water leakage at pump.
Inner seals are damaged.
Install seal kit.
64
Agitation control valve is closed.
Open agitation valve B.
35
Pressure adjustment is over
sensitive.
Incorrect agitation orifice.
Install smaller orifice to increase
pressure.
35
One boom does not spray when
control switches on the Micro-Trak
monitor are activated.
Poor electrical connection to the
electric boom control valves.
Inspect electrical connections to
boom control valves and inspect
for bare or damaged wires.
44
Boom Control
Restrictor disk located in the
hydraulic solenoid manifold on
the sprayer mast is blocked by
contamination.
Remove the solenoid valve
cartridge and remove restrictor
disk. Clear obstruction from
orifice and replace disk and
solenoid valve cartridge.
77
Sprayer attachment not properly
connected to the electrical
connector of the tractor.
Ensure electrical connectors to
the tractor are properly
connected.
27
Boom control functions are slow or
do not respond.
Poor electrical connection to the
hydraulic solenoids.
Inspect electrical connections to
hydraulic solenoids and inspect
for bare or damaged wires.
