Operating Instructions
Types of Spray Gun
Set-Ups
(CONVENTIONAL AND HVLP)
SIPHON FEED CUP SET-UP
The air pressure for atomization is con-
trolled by the regulator on the air source.
The amount of fluid is adjusted by the
fluid control knob, the paint viscosity, and
the air pressure (See Figure 2). The siphon
cup must be vented to the atmosphere.

PRESSURE FEED CUP SET-UP
Air pressure for atomization is con-
trolled by the regulator on the air
source. The fluid pressure is set by
adjusting the cup regulator. The
amount of fluid is also adjusted by the
fluid control knob (See Figure 3). This
method is required for heavy fluids and
when using internal mix nozzle spray-
ing. This method generally requires a
special fluid tip, needle and air cap set.

PRESSURE FEED TANK SET-UP
This method is the same as the pressure
feed cup set-up except that the gun can
be oriented in any position independent
of the tank (See Figure 4). This method
is useful for medium production or large
scale spraying applications.
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.

GRAVITY FEED CUP SET-UP
This method is similar to the siphon
feed with cup except that the cup is
positioned above the spray gun body
(See Figure 5). This creates a positive
fluid pressure in the fluid nozzle.

Preparation
Air Source
1. Thoroughly mix the paint in accordance
with the manufacturer's instructions,
adding thinner where necessary. Most
materials will spray readily if thinned
properly. Strain material through cheese
cloth or a paint strainer. Test the consis-
tency of the material by making a few
strokes on a cardboard target. If mate-
rial still appears too thick, add a small
amount of thinner. THIN WITH CARE!!
WATER/OIL IN COMPRESSED AIR
Failure to install appropriate water/oil removal equipment
may result in damage to machinery or workpiece.

2. Fill the canister about 3/4 full and
start the air compressor.
3. Set up a piece of cardboard or other
scrap material to use as a target and
adjust for best spray pattern.
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 6). Hand tighten
lock ring after adjustment.

PATTERN ADJUSTMENT
SIPHON AND GRAVITY FEED
1. Adjust air pressure to the spray gun
according to the recommendations
supplied with spray material. This air
pressure usually falls between 40 - 60
psi. Adjust air pressure with trigger
pulled and air control knob (if applica-
ble) fully open. If reduced air pressure
is desired for some areas of spray job,
use air control knob to reduce pressure
as necessary (See Figure 7).

2. Set pattern size to desired shape. For
full pattern, open pattern control
knob by turning counterclockwise. For
a round pattern, turn pattern control
knob clockwise (See Figure 8).
