Turn off engine and remove key.
Get out of the tractor and inspect
the spray system for leaks.

There is not enough hydraulic oil
flow to the pump.
The reel speed dial is not turned
to maximum and the conveyor
speed dial is not turned to 6.

Sprayer nozzle tip is plugged.
Carefully remove nozzle tip from
nozzle body and flush with clean
water.
64
Sprayer nozzle tip is worn.
Replace worn nozzle tip with a
new part purchased from your
local dealer or TeeJet distributor.
64
Line strainer is plugged.
Remove cup and screen, flush
thoroughly with clean water.
65
Insufficient line pressure or spray
output.
Solution tank is nearly empty.
Check solution level in tank.
The pressure gauge displays a
reading that fluctuates rapidly and
erratically during spray application.
The servo valve cannot control
the flow to the booms because
sprayer pump output is too great.
Reduce the flow to the sprayer
pump by turning the reel speed
or conveyor speed dials until the
rate controller readings fluctuate
normally. Ensure the nozzle
pressure is matched with the
application rate for the selected
nozzle tip and application speed.
