Graco 310692C Manual De Usuario

Follow Pressure Relief Procedure, page 13 when 
you stop spraying and before cleaning, checking, ser-
vicing, or transporting equipment. Read warnings, 
page 3. 

Fluid flow is fluttering while spraying. 1.

Fluid nozzle not tight enough.

2.

Fluid filter clogged.

3.

Fluid source empty.

1.

Tighten fluid nozzle to 40 in-lb 
(4.5 N•m).

2.

Check fluid filter.

3.

Refill

Fluid flow fades while spraying high 
viscosity fluids.

1.

Air hose size is too restricted for 
higher air flow being used.

1.

Use 5/16 in. (7.9 mm) I.D. air 
hose if the hose is 25 ft. (7.6 m) 
long. If longer hose is needed, 
use a 3/8 in. (9.5 mm) I.D. hose.

Pattern becomes off-set or heavy on 
ends.

1.

Air cap horn holes plugged or 
damaged.

2.

Nozzle tip dirty or damaged.

1.

Clean air cap horn holes with 
non-metallic item such as a 
toothpick, or replace air cap.

2.

Clean or replace nozzle.

Gun fluid pressure is too high with 
gun triggered (cannot achieve 
desired flow rate).

Using needle/nozzle kit with too small 
orifice.

Use needle/nozzle kit with larger ori-
fice.

Using a low fluid pressure setting, the 
fluid flow is too high, making it neces-
sary to restrict needle travel to 
reduce fluid flow.

Using needle/nozzle kit with too large 
orifice.

Use needle/nozzle kit with smaller 
orifice.

Fluid system will not operate at low 
enough fluid pressure [below 10 psi 
(70 kPa, 0.7 bar)].

There is no fluid regulator, or air reg-
ulator or pressure pot is not sensitive 
enough at low pressures.

Add low pressure fluid regulator, or 
add more sensitive low pressure air 
regulator on pressure pot.
