experiencing is not listed in the below table or in either of the engine or air compressor troubleshooting
sections, contact the manufacturer for service and support.
SYMPTOM
1)
Machine will not spray
2)
Air pressure increases @ constant engine
RPM's
3)
Spray continues when valve closed
4)
No air flow through nozzle
5)
Too much fluid flow through nozzle
6)
Too little fluid flow through nozzle
7)
Atomization droplets too large
8)
Atomization droplets too small
PROBABLE CAUSE
Formulation tank empty
Air/vacuum leak
Clogged formulation filter
Valve not opening
broken, melted, or clogged formulation feed tube
Nozzle clogged
Nozzle clogged
Fauty air pressure gauge
Valve not closing completely
Belt loose, broken, or slipped off pulley/flywheel
supply hose not connected
Supply hose broken
Pressure relief valve stuck open
Engine off
Oriface disk missing
Oriface disk too large
Oriface disk too small
Nozzle clogged
Air/vacuum leak
Clogged formulation filter
low engine rpm/low air pressure
Oriface disk too large
Nozzle gumming up or varnishing
Engine RPM and air pressure too high
Oriface disk too small

REMEDY
Add formulation
Tighten all fittings from forulation tank to nozzle
check and if necessary clean in-line filter
Verify manual/electrical valve open at nozzle and formulation
has free path to nozzle
Check all tubing from formulation tank to nozzle
Remove and clean nozzle tip
Remove and clean nozzle tip
Replace gauge
Check and/or clean valve for posible contaminates
Check and if necessary , replace or repair
Connect
Check for worn area, holes, or fitting breaks
Decrease engine RPM, or check replace relief valve
Start engine
Add oriface disk
Reduce size of oriface disk diameter
Increase oriface disk diamter
Remove and clean nozzle tip
Tighten all fittings from forulation tank to nozzle
check and if necessary clean in-line filter
Increase engine RPM to increase air pressure
Reduce size of oriface disk diameter
Clean nozzle, soak in industrial cleaners if applicable
Reduce engine RPM to decrease air pressure
Increase size of oriface disk diameter
