Pistola Pulverizadora HVLP Alimentada por Gravedad

FAN DIRECTION

The direction of the fan (horizontal or
vertical) can be changed by loosening
the lock ring and turning the air cap 90
degrees (See Figure 3). Hand tighten
lock ring after adjustment.

PATTERN ADJUSTMENT

1. Adjust air pressure to the spray gun

according to the recommendations
supplied with the spray material.
This air pressure usually falls
between 40 - 60 psi.

Do not
exceed

spray gun maximum pressure.

Adjust air pressure with the trigger
pulled and air control knob (if applic-
able) fully open. If reduced air pres-
sure is desired for some areas of the
spray job, use the air compressor reg-
ulator or air control knob to reduce
pressure as necessary (See Figure 4).

2. Set pattern size to desired shape.

For full pattern, open pattern con-
trol knob by turning counterclock-
wise. For a round pattern, turn pat-
tern control knob clockwise
(See Figure 5).

3. Turn fluid control knob fully clock-

wise until closed (See Figure 5).

4. Trigger a short burst while turning

fluid control knob counterclockwise.
Observe the spray pattern on the tar-
get and adjust the fluid control knob
until the desired pattern (atomiza-
tion) is obtained (See Figure 6).

If the spray is too fine (excessive over-
spray), caused by too much air for the

amount of paint being sprayed, reduce
the air pressure or open the fluid con-
trol to spray more material.

If the spray is too coarse (spitting globs),
reduce the amount of material with the
fluid control knob or thin the paint.

5. The fluid control knob can be used

to finely adjust pattern consistency.

Before spraying the workpiece, practice
a few minutes on a cardboard target to
ensure the pattern size and consistency
are set correctly.

Operation

1. Begin spraying.

Always keep
the gun at
right angles to
the work (See
Figure 8).

2. Keep the noz-

zle about 6 to
9 inches from
the work sur-
face through-
out the stroke
and always
keep the gun

WATER/OIL IN COMPRESSED AIR

All compressor pumps discharge some condensed water, oil or contaminates with
the compressed air.

IMPORTANT: This condensation will cause “fish eyes” to appear in the paint
job. Install appropriate water/oil removal equipment and controls as necessary
for the intended application. Locate filter as close to spray gun as possible.

Failure to install appropriate water/oil removal

equipment may result in damage to machinery or

workpiece.
