WHAT TO
LOOK FOR WHAT COULD HAPPEN

Flammable

Spray Materials

Toxic Vapors

Compressed Air

Pressurized Parts

When paints or materials are sprayed, they are broken
into very small particles and mixed with air. This will
cause certain paints and materials to become extremely
flammable.

Some paints and coatings may be harmful if inhaled or
allowed to come into contact with skin or eyes.

Compressed air may propel dirt, metal shavings, etc.
and possibly cause an injury.

Certain parts are under pressure whenever the gun is
connected to a pressurized air line. These parts may be
propelled if the gun is disassembled.

HOW TO PREVENT IT

Never spray near open flames or pilot lights in stoves or
heaters.

Never smoke while spraying.

Provide ample ventilation when spraying indoors.

Use a mask or respirator if there is a chance of inhaling
toxic sprayed materials. Masks and respirators have
limits and will only provide protection against some
kinds and limited amounts of toxic material. Read mask
and respirator instructions carefully. Consult with a safety
expert or industrial hygienist if you are not sure about the
use of a certain mask or respirator.

Never point any nozzle or sprayer toward a person or part
of the body.

Always wear ANSI Z87 safety goggles or glases when
spraying.

Disconnect the gun from the air line, or completely
depressurize the air line whenever the gun is to be
disassembled.

Explosion
Hazard ­Incompatible
Materials

The solvents 1,1,1-Trichloroethane and Methylene
Chloride can chemically react with the aluminum used
in most spray equipment, and this gun and cup, to
produce an explosion hazard.

2 — Eng

Read the label or data sheet for the material you intend to
spray.

1. Do not use any type of spray coating material
containing these solvents.

2. Do not use these solvents for equipment
cleaning or flushing.

3. If in doubt as to whether a material is compatible,
contact your material supplier.

GENERAL INFORMATION

AIR CAPS

External Mix - The air and material are mixed outside
the air cap. This type of cap is best suited for quick
drying paints, such as latex, lacquers, etc.

Internal Mix - The air and material are mixed inside the
air cap. This type of cap is normally used for thick paint
where fast application is desired and where quality of
finish is less important. Internal mix must be used with
pressure feed set-up.

Fluid/Fan Adjustment- To increase volume of mate­rial, turn fluid needle adjusting screw counterclock­wise. To decrease, turn clockwise. Increasing volume of
material will also increase fan pattern size when using
a fan pattern air cap.

PREPARATION FOR SPRAYING

This spray gun is shipped completely assembled, and
set-up spraying. Installation is accomplished by con­necting an air line to the air inlet adapter.

This spray gun should be flushed with solvent prior to
spraying with paint.

To change air caps, turn the retaining ring counter­clockwise and remove from gun.

Remove air cap and replace with different cap.
Reassemble in reverse order.

NOTE
Matched air cap and fluid tip combina­tions are recommended for optimum per­formance. The fluid tip is removed with a
1/2" socket. When assembling, be sure
the plastic baffle is in place and the tip is
not cross threaded or over tightened (160­220 in.-lbs. Torque).

Be sure the surface to be sprayed is dry and free of all
dirt, grease, oil and loose paint. Mix and prepare the
paint according to the manufacturer's instructions. The
use of a viscosimeter can be very helpful. Strain the
material to be sprayed through a 60 to 90 mesh screen or
equivalent.

The fluid needle packing in this gun may be loose when
received. Tighten the packing retainer until it grabs and
holds the fluid needle , then back off the packing retainer
(approx. 1/4 turn) until the fluid needle is free to travel
into the fluid tip.

OPERATION

1. Shut off fluid flow through gun by turning fluid
needle adjusting screw clockwise as far as it will go.
Do not force.

2. Keep the air pressure as low as possible. Set pressure
to 40 psi as a starting point.

RISK OF INJURY OR EQUIPMENT DAMAGE.
DO NOT EXCEED 50 PSIG AT ANY TIME

3. Open (turn counterclockwise) air valve assembly
until the first thread is flush with the back of gun. This
is the full open position.

To use a quick disconnect, remove the air hose adapter
and install a 1/4" NPT quick disconnect adapter into the
handle of the gun body. Set air pressure at 40 psi as a
starting point and follow the safety precautions before
you begin.

4. Hold the trigger back and gradually open the fluid
needle adjusting screw until a desired pattern is
obtained.

5. Trigger the gun quickly, one second on-off. Spray a
small test pattern.

6. If the gun sprays too fast (runs or sags), lower the air
and fluid pressure. If too slow, increase pressure.
Adjust to balance pressure.

When using internal mix air cap, begin with the same air
and fluid pressure.
