TROUBLESHOOTING
Troubleshooting guidelines are outlined for both the engine and air compressor in the corresponding
owner’s manuals of each. For problem identification, refer to these manuals for further guidance. For
all other troubleshooting symptoms, refer to the table below. If the troubleshooting symptom you are
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
PROBABLE CAUSE
REMEDY
1)
Machine will not spray
Formulation tank empty
Add formulation
Air/vacuum leak
Tighten all fittings from forulation tank to nozzle
Clogged formulation filter
check and if necessary clean in-line filter
Valve not opening
Verify manual/electrical valve open at nozzle and formulation
has free path to nozzle
broken, melted, or clogged formulation feed tube
Check all tubing from formulation tank to nozzle
Nozzle clogged
Remove and clean nozzle tip
2)
Air pressure increases @ constant engine
Nozzle clogged
Remove and clean nozzle tip
RPM's
Fauty air pressure gauge
Replace gauge
3)
Spray continues when valve closed
Valve not closing completely
Check and/or clean valve for posible contaminates
4)
No air flow through nozzle
Belt loose, broken, or slipped off pulley/flywheel
Check and if necessary , replace or repair
supply hose not connected
Connect
Supply hose broken
Check for worn area, holes, or fitting breaks
Pressure relief valve stuck open
Decrease engine RPM, or check replace relief valve
Engine off
Start engine
5)
Too much fluid flow through nozzle
Oriface disk missing
Add oriface disk
Oriface disk too large
Reduce size of oriface disk diameter
6)
Too little fluid flow through nozzle
Oriface disk too small
Increase oriface disk diamter
Nozzle clogged
Remove and clean nozzle tip
Air/vacuum leak
Tighten all fittings from forulation tank to nozzle
Clogged formulation filter
check and if necessary clean in-line filter
7)
Atomization droplets too large
low engine rpm/low air pressure
Increase engine RPM to increase air pressure
Oriface disk too large
Reduce size of oriface disk diameter
Nozzle gumming up or varnishing
Clean nozzle, soak in industrial cleaners if applicable
8)
Atomization droplets too small
Engine RPM and air pressure too high
Reduce engine RPM to decrease air pressure
Oriface disk too small
Increase size of oriface disk diameter
