Basic Troubleshooting

312004B

When paint is sprayed, it runs down the 
wall or sags.

Coat is going on too thick.

Move gun faster.

Choose a tip with smaller hole size.

Choose tip with wider fan.

Make sure gun is far enough from 
surface.

When paint is sprayed, coverage is 
inadequate.

Paint coating is going on too thin.

Move gun slower.

Choose tip with larger hole size.

Choose tip with narrower fan.

Make sure gun is close enough to 
surface.

Fan pattern varies dramatically while 
spraying.

OR

Sprayer does not turn on promptly when 
resuming spraying.

SR7, ProX7 and ProX9 - Pressure control 
switch is worn and causing excessive 
pressure variation.

Take sprayer to Graco/M

AGNUM

 

authorized service center.

Cannot trigger spray gun.

Spray gun trigger lock is locked.

Rotate trigger safety lever to unlock 
trigger lock, page 14.

Paint is coming out of pressure control 
switch.

SR7, ProX7 and ProX9 - Pressure control 
switch is worn.

Take sprayer to Graco/M

AGNUM

 

authorized service center.

Prime/Spray valve actuates automatically 
relieving pressure through prime tube.

System is over pressurizing.

Take sprayer to Graco/M

AGNUM

 

authorized service center.

Paint leaks down outside of pump.

Pump packings are worn.

Replace pump packings. 

Motor is hot and runs intermittently. 
Motor automatically shuts off due to 
excessive heat. Damage can occur if 
cause is not corrected.

Thermal Overload

, page 5. 

Vent holes in enclosure are plugged or 
sprayer is covered.

Keep vent holes clear of obstructions and 
overspray and keep sprayer open to air.

Extension cord is too long or not a heavy 
enough gauge.

Replace extension cord. Read 

Grounding and Electrical 
Requirements

, page 5.

Unregulated electrical generator being 
used has excessive voltage.

Use electrical generator with a proper 
voltage regulator. Sprayer requires 
120VAC, 60 Hz, 1500-Watt generator.

Sprayer was operated at high pressure 
with very small tip which causes frequent 
motor starts and excessive heat build up.

Decrease pressure setting or increase tip 
size.

Building circuit breaker opens after 
sprayer operates for 5 to 10 minutes.

Too many appliances are plugged in on 
same circuit.

Free up circuit (unplug things), or use a 
less busy circuit.

Sprayer electrical cord is damaged.

Check broken insulation or wires. 
Replace electrical cord if damaged.

Extension cord is damaged or too long or 
not a heavy enough gauge.

Plug in something that you know is 
working to test extension cord.

Replace extension cord.

Prox7 and ProX9 - Fold ‘n Store handle 
does not actuate

Dirty or dried paint 

Clean handle parts.
