Operating Instructions

 When spraying and cleaning, always

follow the instructions and safety
precautions provided by the material
manufacturer (Refer to MSDS).

 Do not overreach. Keep

proper footing and balance
at all times. Proper footing
and balance enables better
control of the spray gun in
unexpected situations.

 Stay alert. Watch what you are doing

and use common sense when operat­ing the spray gun. Do not use the
spray gun while tired or under the
influence of drugs, alcohol, or medica­tion. A moment of inattention while
operating the spray gun increases the
risk of injury to persons.

TOOL USE AND CARE

 Do not use pressure that

exceeds operating pres­sure of the spray gun or
any of the parts (hoses,
fittings, etc.) in the paint­ing system.

 Over pressurizing the spray gun is

able to result in bursting, abnormal
operation, breakage of the spray gun
or serious injury to persons.

 Always verify prior to using the spray

gun that the air source has been
adjusted to the rated air pressure or
within the rated air-pressure range.

 Check for misalignment or binding of

moving parts, breakage of parts, and
any other condition that affects the
spray gun’s operation. If damaged,
have the spray gun serviced before
using. Many accidents are caused by
poorly maintained spray guns. There
is a risk of bursting if the spray gun
is damaged.

 Avoid unintentional starting. Be sure

the trigger is off before connecting
to the air supply. Do not carry the
spray gun with your finger on the
trigger or connect the spray gun to
the air supply with the trigger on.

 Disconnect the spray gun from the air

source before, changing accessories,
cleaning, servicing or storing the
spray gun. Such preventive safety
measures reduce the risk of starting
the spray gun unintentionally.

 Failure to install appropriate

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

 Always use a pressure regulator on

the air supply to the spray gun.

Introduction

The spray gun is a vital link in any finish­ing application. In addition to operating
the spray gun properly, techniques of
surface preparation and paint prepara­tion must be understood. These instruc­tions will explain the differences among
various spray technologies and serve as
a guide in the proper operation and
techniques of spray painting. Refer to
the Replacement Parts Manual for
model specific information.

SPRAY GUN TERMS
Atomization - Conversion of bulk liq-

uid to spray droplets (mist).
Bleeder – In this mode, air passes continu-

ously 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.

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

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.

Feed – Method used to bring paint
into the gun for spraying.

Fluid Control Knob – Used to control the
amount of paint being mixed with air.

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.

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.

Mix – The mixing of paint and air
when spraying.

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.

Paint Tank – An auxiliary pressurized
paint reservoir that allows continuous
spraying of large amounts of paint with­out stopping for refills as with a canister. It
also allows using the spray gun at any
angle without causing paint to drip.

Pattern Control Knob – Used to form
the proper pattern (size and shape) of
paint as it is sprayed from the gun to
the workpiece.

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
used with light bodied paints.

Viscosity – A measurement of the
resistance to the flow of liquids.

CONVENTIONAL VS. HVLP

Conventional spray guns use a much
higher air cap pressure to atomize
paint than HVLP spray guns. This
results in more overspray and a lower
transfer efficiency.

HVLP, electrostatic and airless processes
are currently the only compliant spray
methods that meet the strict 65% trans­fer efficiency criteria required by some
air quality management districts. This
enhanced transfer efficiency results in a
significant material savings compared
to conventional spraying. Check local,
state and national regulations that may
be in effect before performing any
spraying operations.

HVLP spraying is a growing trend in the
finishing industry due to its environmen­tal friendliness. By definition, dynamic
air pressures in the air cap must be 10
psi or less to qualify as HVLP. A soft, low
velocity pattern is
produced which
increases control
and reduces
bounceback and
overspray (See
Figure 1). For
these reasons,
HVLP is also well
suited for spraying
parts with
recessed areas.

Spray Gun Set-up

The pressure for atomization is con­trolled at the air source. The amount of
fluid is adjusted by the fluid control
knob, the paint viscosity and the air
pressure.

The gravity feed cup screws onto the top
of the gun body creating a positive fluid
pressure in the nozzle (See Figure 2).

Preparation

1. Thoroughly mix and thin paint in
accordance with the paint manufac­turer’s instructions. Most materials
will spray readily if thinned properly.

2 Strain material through cheese

cloth or a paint strainer.

3. Fill the canister about 3/4 full and
start the air compressor.

4. Set up a piece of cardboard or other
scrap material to use as a target and
adjust for best spray pattern.

5. 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!! Do not
exceed paint manufactuer’s thinning
recommendations.

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 maxi-

mum pressure.

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 the air compressor regulator or
air control knob to reduce pressure as
necessary (See Figure 4).

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).

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.

Operating Instructions

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.

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 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 mid-stroke 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).

3. 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).

4. 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.

5. 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.

6. 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 paint manufacturer’s
recommendations for the use and dis­posal of spray materials and solvent.

Clean spray gun

immediately after
use. Paint and other materials 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 (exam­ple: lacquer thinner for lacquer, etc.).

1. 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 sol­vent 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.

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 o­rings 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 fluid needle
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 5). Do not over-tighten a
packing nut because this will
restrict movement of the needle.
