Spray Gun Terms

FEED – Method used to bring paint

into the gun for spraying.
PRESSURE FEED – Method of paint

feed where a canister or paint tank is
pressurized to force paint to the gun.
Either internal or external mix air caps
are used with this method. Pressure feed
is generally used for spraying heavy bod­ied paints or for large size projects.

SIPHON FEED – Method of paint feed
where atmospheric pressure creates a
partial vacuum to siphon paint to the
gun. Only external mix air caps are
used with this method. Siphon feed is

IN285500AV 12/02

used with light bodied paints.
GRAVITY FEED – Method of paint feed

similar to the siphon feed method.
However, the cup is inverted to create a
positive fluid pressure at the nozzle.

MIX – The mixing of paint and air
when spraying.

INTERNAL MIX – Process where the air
and paint are mixed inside the air cap
just before being sprayed. This method
is best for heavy bodied, slow drying
paints and can only be used with the
pressure feed method. Do not use fast
drying paints with internal mix. The
paint will dry inside and quickly clog
the air cap.

EXTERNAL MIX – Process where the air
and paint are mixed just after leaving
the nozzle. This type of mix should be
used for fast drying paints and when a
high quality finish is needed.

BLEEDER/NON-BLEEDER – Indicates
whether air flows through the gun con­tinuously or as the trigger is pulled.

BLEEDER – In this mode, air passes con­tinuously through the gun whether
spraying or not. This mode is generally
used when the air is supplied by a con­tinuously running compressor that does
not have a tank.

NON-BLEEDER – In this mode, air flows
only when the trigger is pulled. This
type of operation is used with a com­pressor equipped with a tank or with a
large factory air system.

VISCOSITY – A measurement of the
resistance of the flow of a liquid.

ATOMIZATION - Conversion of liquid
to spray droplets (mist).

PATTERN CONTROL KNOB – Used to
form the proper pattern (size and

General Safety
Information

1. Read all manuals included
with this product careful­ly. Be thoroughly familiar
with the controls and the
proper use of the equip­ment.

2. Follow all local electrical and safety
codes as well as in the United States,
the National Electrical Codes (NEC)
and Occupational Safety and Health
Act (OSHA).

Use a face mask/respira­tor and protective cloth­ing when spraying.
Always spray in a well
ventilated area to pre­vent health and fire hazards. Refer to
Material Safety Data Sheets (MSDS) of
spray material for details.

Never spray closer than
25 feet to the compres­sor! If possible, locate
compressor in separate
room. Never spray into the compressor,
compressor controls or the motor.

3. Do not smoke or eat when spraying
paint, insecticides, or other flamma­ble substances.

Do not spray flammable
materials in vicinity of
open flame or near igni­tion sources. Motors, electrical equip­ment and controls can cause electrical
arcs that will ignite a flammable gas or
vapor. Never store flammable liquids
or gases in the vicinity of the compres­sor.

4. When spraying and cleaning, always
follow the instructions and safety
precautions provided by the material
manufacturer (Refer to MSDS).

Do not spray acids,

corrosive materials,
toxic chemicals, fertilizers or pesticides.
Using these materials could result in
death or serious injury.

5. Keep visitors away and NEVER allow

children or pets in the work area.

Never aim or

spray at yourself or
anyone else or serious injury could
occur.

6. Always work in a clean environment.

To avoid injury and damage to the
workpiece, do not aim the spray gun
at any dust or debris.

Do not use pressure that
exceeds the operating
pressure of any of the
parts (hoses, fittings,
etc.) in the painting system.

Keep hose away

from sharp objects.
Bursting air hoses may cause injury.
Examine air hoses regularly and replace
if damaged.

7. Always use a pressure regulator on

the air supply to the spray gun.

Failure to install

appropriate
water/oil removal equipment may
result in damage to machinery or work­piece.

Types of Spray Gun
Set-Ups

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

1). 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 2). This
method is required for heavy fluids and
when using internal mix nozzle spray­ing. This method generally requires a
special fluid tip, needle and air cap set.

Types of Spray Gun
Set-Ups

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 3). This method
is useful for medium production or
large scale spraying applications.

Preparation

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 consistency of
the material by making a few strokes
on a cardboard target. If material still
appears too thick, add a small
amount of thinner. THIN WITH CARE!

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 4). Hand tighten
lock ring after adjustment.

PATTERN ADJUSTMENT

SIPHON FEED

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. Adjust air pressure with the
trigger pulled and air control knob
(if applicable) fully open. If reduced
air pressure is desired for some areas
of the spray job, use air control knob
to reduce pressure as necessary (See
Figure 5).

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 6).

3. Turn fluid control knob fully clock­wise until closed (See Figure 6).

4. Trigger a short burst while turning
fluid control knob counterclockwise.
Observe the spray pattern on the tar­get and adjust the fluid control knob
until the desired pattern (atomiza­tion) is obtained (See Figure 7).

If the spray is too fine (excessive over­spray), caused by too much air for the
amount of paint being sprayed, reduce
the air pressure or open the fluid con­trol 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.

PRESSURE FEED SET-UP

1. Adjust air pressure to the spray gun
according to the recommendations
supplied with the spray material. This

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.

Failure to install appropriate water/oil removal equipment
may result in damage to machinery or workpiece.

Preparation (Cont.)

air pressure usually falls between 40 ­60 PSI. Adjust air pressure with the
trigger pulled and air control knob
(if applicable) fully open. If reduced
air pressure is desired for some areas
of the spray job, use air control knob
to reduce pressure as necessary (See
Figure 5).

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 6).

3. Open the fluid control knob by turning
counterclockwise about three turns.

4. Start the tank pressure at 0 PSI and
turn the tank regulator slowly to
increase fluid delivery until the
desired pattern consistency (atomiza­tion) is reached.

5. If the atomization is too coarse,
reduce the tank pressure with the
tank regulator. Trigger a short burst
or open relief valve to relieve the
pressure, then increase pressure slow­ly to obtain proper pattern consisten­cy (See Figure 7).

6. 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).

Keep the nozzle
about 6 to 9 inches
from the work sur­face throughout the
stroke and always
keep the gun in
motion while spray­ing. Stopping gun
movement in mid­stroke will cause a
build up of paint
and result in “runs.”
Do not “fan” the
gun from side to side while painting. This
will cause a build-up of paint in the center
of the stroke and an insufficient coating at
each end (See Figure 9).

2. “Trigger” the gun properly. Start the
gun moving at the beginning of the
stroke BEFORE SQUEEZING THE TRIG­GER and release the trigger BEFORE
STOPPING GUN MOVEMENT at the
end of the stroke. This procedure will
“feather” (blend) each stroke with
the next without showing overlap or
unevenness (See Figure 10).

3. The amount of paint being applied

can be varied by the speed of the
stroke, distance from the surface and

adjustment of the fluid control
knob.

4. Overlap strokes just enough to
obtain an even coat (See Figure 11).
NOTE: Two thin coats of paint will
yield better results and have less
chance of runs than one heavy layer.

5. Use a piece of cardboard as a shield
to catch overspray at the edges of
the work to protect other surfaces.
Use masking tape to cover other
areas if needed.

Maintenance

DAILY CLEAN-UP

Local codes may require specific clean­ing methods and equipment. Follow
local codes and manufacturer’s recom­mendations for the use and disposal of
spray materials and solvent.

Clean spray gun

immediately after
use. Paint and other material dry quick­ly in the small passages rendering gun
useless due to the difficulty of remov­ing hardened paint from the passages
inside the gun.

NOTE: In the instructions below, the use
of the word “solvent” refers to the spe­cific solvent for the material used (eg:
lacquer thinner for lacquer, etc ).

1. Spray guns with canister—Remove

and empty the canister; then rinse
with a solvent recommended for the
paint or other material used.

2. Refill canister with clean solvent and

attach to the gun. Spray solvent
through the gun while shaking the
gun vigorously. Wipe the gun exteri­or with a solvent soaked rag. Repeat
until the gun is clean.

3. Remove the air cap and soak in sol

vent until clean. Use a small brush for
stubborn stains if necessary.
Toothpicks or small brushes may be
used to clean air passages; however,

NEVER USE METAL OBJECTS TO
CLEAN PRECISELY DRILLED PAS­SAGES. DAMAGED PASSAGES
WILL CAUSE IMPROPER SPRAYING.

4. Clean gaskets with a solvent soaked
rag. To prevent equipment damage,

Do not immerse gaskets or spray
gun body in solvents.

5. After using water to clean out water
based paints or materials, spray min­eral spirits through the gun to pre­vent corrosion.

6. Use a non-silicone oil on all moving
parts when reassembling. Use
Vaseline

®

or light grease on all thread-

ed connections prior to storage.

7. Clean and flush gun thoroughly to
neutralize any contaminants corro­sive to the spray gun.

CLEANING A GUN USED WITH A PAINT
TANK

Shut off the air supply to
the tank and release the
pressure in the tank.

1. Open the vent on the paint tank. If
using an external mix air cap, loosen
the cap slightly.

2. Reduce air pressure to 10-20 PSI. Hold
a piece of cloth, wadded in the hand,
tightly around the air cap opening(s)
and pull the trigger. The air will back
up through the fluid tip and force
the paint out of the hose and back
into the tank.

3. Pour the paint from tank and use sol­vent and rags to clean.

4. Put enough solvent into the tank to
wash the hose and gun thoroughly.
Close the tank and spray from the
gun until the solvent comes out clean.

5. Remove and blow out the material
hose with compressed air to get rid
of any trace of solvent in the hose.

When blowing out

the hose, the open
end should be aimed away from any
person to avoid blowing solvent into
the eyes or on the skin causing possible
injury.

PERIODIC CLEAN-UP

Due to improper cleaning and paint it
may be necessary to inspect and clean
the internal parts and the gun body.

1. Examine openings in air cap and fluid

tip. If clogged, remove any o-rings
and soak the air cap or fluid tip in
solvent.

2. A brush or toothpick or something

similar may be used to dislodge the
dried paint from holes and passages.

NEVER USE METAL OBJECTS TO
CLEAN PRECISELY DRILLED PAS­SAGES. DAMAGED PASSAGES
WILL CAUSE IMPROPER SPRAYING.

3. Remove and check the adjusting nee-

dle for excessive wear at the tip and
straightness.

IMPORTANT: If the needle tip is worn
more on one side than the other, either
the needle is bent or the gun body has
been dropped or knocked out-of-line.
There are no adjustments that can be
made to a bent gun body. Test the nee­dle by rolling on a flat surface. Replace
if necessary.

4. Check and replace any damaged o­rings and seals. O-rings and seals can be
wiped clean but not soaked in solvent.

5. Unscrew packing nuts and replace
the packing ONLY if a leak will not
stop when the nut is tightened (See
Figure 12). Do not over-tighten a
packing nut because this will restrict
movement of the needle.

6. Re-assemble in reverse order of
above and use a non-silicone oil on
moving parts. Apply Vaseline

®

or
light grease on threaded joints and
hose connections.

STORING

1. When not using spray gun, turn the
fluid adjustment knob counterclock­wise to open which will reduce
spring tension on needle fluid tip.

2. Spray gun MUST BE well cleaned
and lightly lubricated.
