Solutions
Pressure
decreasing
Between gauge
and liquid supply
Pump wearing
Rebuild or replace pump
Plugged suction or pump to pressure
head hose
Clean hose and reduce cause of clogging
Plugged Whirlfilter
Clean Out Solution Whirlfilter®
Plugged gauge
Remove the quick disconnect fitting and flush
gauge protector
Pressure
fluctuating
Between pump
outlet and liquid
Check suction hose & fittings for air
leaks. Air in system is indicated by
buffs of air at nozzles
Remove obstruction from clogged area
Vortex in tank suction
Align agitators properly
Cracked pump housing
Replace pump housing
Pressure
increasing
Between gauge
and nozzle
Nozzle screens clogged
Clean screens
Nozzle orifices plugged
Remove material with soft brush or air
Boom hoses becoming clogged
Remove obstruction from clogged area
Boom hoses pinched
Use cable ties to position hose so it will not kink
Pressure
cannot
increase
Pump or electric
ball valve
From nozzle charts check liquid
demand against pump capacity
(nozzle requi agitation
requirement)
Reduce swath width by nozzle reduction; install
smaller nozzles and drive at a lower rate of speed
Electric ball valve or gauge not
functional
Replace or repair
Pressure adjust switch faulty
Test switch & replace if faulty
Fuse is out in control box
Replace fuse
Manual pressure adjustment valve
not all the way open
Open the manual pressure valve all the way and
allow the electric ball valve to govern the pressure
No pressure
Plumbing
Tank shut-off valves off
Make sure all tank shut-off valves are open
Loose fittings
Tighten fittings so pump can prime
Collapsed suction hose to pump
Replace hose
Obstruction in suction hose or tank
Remove obstruction
No pressure
Pump
Hydraulic pump running in the wrong
direction
Switch hydraulic hoses in the tractor outlet
PTO pump coupler loose
Tighten PTO coupler
Pressure
cannot
decrease
Pump or electric
ball valve
Tank agitation restricted
Check that the agitator valve is open and that the
liquid is being agitated
Liquid will not
induct
Chemical
Inductor
Make sure the valve below the
inductor tank is open
Make sure the pump is in operation
and has prime
Make sure the venturi bypass valve is
open

Chemical
Inductor
Close valve below inductor tank until
pump is running, has pressure and
venturi valve is open
