WHAT COULD HAPPEN HOW TO PREVENT IT
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 and could result in
serious injury or death.
Never spray near open flames or pilot lights in
stoves or heaters.
Never smoke while spraying.
Provide ample ventilation when spraying indoors.
WHAT COULD HAPPEN HOW TO PREVENT IT
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 and could
result in serious injury or death.
Read the label or data sheet for the material you
intend to spray.
1. Never use any type of spray coating material
containing these solvents.
2. Never use these solvents for equipment cleaning
or flushing.
3. If in doubt as to whether a material is compatible,
contact your material supplier.
WHAT COULD HAPPEN HOW TO PREVENT IT
Use a NIOSH approved mask or respirator and pro-
tective clothing designed for use with your specific
application and spray materials. Some masks
provide only limited protection against toxic materials
and harmful paint solvent. Consult with a Safety
Expert or Industrial Hygienist if uncertain about your
equipment or materials.
Some paints, coatings and solvents may cause lung
damage, and burns if inhaled or allowed to come
into contact with skin or eyes.
WHAT COULD HAPPEN HOW TO PREVENT IT
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.
Compressed air may propel dirt, metal shavings,
etc. and possibly cause an injury.
Prolonged exposure to air spray can result in per-
manent damage to hearing.
Disconnect the gun from the air line, or completely
depressurize the air line whenever the gun is to be
disassembled.
Never point any nozzle or sprayer toward a person
or part of the body.
Always wear ANSI 278.1 safety approved goggles
or glasses when spraying.
Spray guns operate at pressures and velocities
high enough to penetrate human and animal flesh,
which could result in amputation or other serious
injury.
! See a physician immediately !

Prior to shipment, this spray gun was treated with an
anticorrosive agent. Before use ,make sure that it is
carefully flushed with thinner.
1. Mix material according the manufacturer’s instructions.
Mixture should be smooth and easily pourable. Lumps or
foreign particles should be removed by straining through
a suitable paint filter.
NOTE: If not using the siphon feed setting, see “Remote
Pressure Feed” paragraphs.
2. Remove the material cup (e) from lid/gun assembly.
NOTE: Slide release lever (f) to the right, rotate lid, and
remove material cup (e).
3. Fill the material cup (e) ¾ full.
4. Attach material cup (e) to the lid/gun assembly and slide release lever (f) to clockwise to secure
in place.
5. Attach air supply line to ¼ NPS air inlet (c).
6. Adjust spray pattern.
a. The position of the air cap horns (g) will determine the spray pattern. Loosen air cap (h) and
rotate horns to achieve desired pattern. Tighten air cap.
b. Amount of material released (density of “fan spray”) is controlled by (d) fluid control knob.
Turn knob counterclockwise to increase, or clockwise to decrease, the fluid flow.
c. Width of “fan spray” is governed by (b) spray pattern control knob. Turn knob counter-
clockwise to increase, or clockwise to decrease, air flow.
7. Depress spray gun trigger fully to spray material. NOTE: Depress trigger partially will cause
only air to be released.
NOTE: Care should be exercised when handling spray gun to avoid damage to the orifice of the air
cap and tip of fluid nozzle. Damage to these part results in irregular spray patterns.
DO NOT ATTEMPT
TO UNCLOG (BACK
FLUSH) SPRAY GUN BY SQUEEZING
TRIGGER WHILE HOLDING FINGER IN
FRONT OF FLUID NOZZLE.
Pressure may vary
according to
viscosity of material used. Maximum
working pressure of gun is 50 psi. DO
NOT EXCEED PRESSURE LIMIT OF
GUN OR ANY OTHER COMPONENT IN
SYSTEM!
Prior to daily
operation, make
certain that all connections and fittings
are secure. Check hose and all con-
nections for a week or worn condition
that could render system unsafe. All
replacement components such as
hose or fittings must have a working
pressure equal to or grarter than
system pressure.

Spraying Tips
1. The stroke is made with a free arm motion, keeping the gun at a right angle
to the surface at all points of the stroke. Arching the stroke will result in
uneven application and excessive over spray at each end of the stroke.
2. Depress trigger just before reaching the edge of the surface to be sprayed.
Hold the trigger fully depressed and move the gun in one continuous
motion. Release the trigger when the other edge of the surface is reached,
shutting off the fluid flow, but continue motion a few inches until it is
reversed for the return stroke. When the edge of the surface is reached on
the return stroke, depress the trigger fully again and continue across the
surface.
3. Lap each stroke 50% over the preceding one. Less than 50% will cause
streaks on the finish surface.
NEVER point spray gun at self or any other person.
Accidental discharge of material may result in serious injury.
NOTE: When replacing lid assembly to gun assembly hand tighten nut ( b)
and tighten securely.
If the material to be sprayed is too heavy for siphon feed or fast application
is desired, convert to the pressure feed.
1. Remove the material cup (e)
lever (f) to the right, rotate lid, and
remove material cup (e).
2. Loosen nut (b). After the nut
is loosened hand turn until lid
assembly can be removed from gun.
3. The gun is now ready to be
connected to any pressure feed tank
with a standard 3/8" straight pipe
female connection. See manufacturer’s
manual for correct procedure.
4. To operate see steps 5-7 in the "Operation" section to continue.
