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.
Disconnect the gun from the air line, or completely
depressurize the air line whenever the gun is to be
disassembled.
Compressed air may propel dirt, metal shavings,
etc. and possibly cause an injury.
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.
Before disassembly or removal of any part of gun or
attached components, shut off compressor, release
pressure by depressing trigger, and disconnect power source. NEVER as-
sume system pressure is zero!
TO AVOID CREATING AN EXPLOSIVE ATMOSPHERE,
WORK ONLY IN WELL VENTILATED AREAS.

D27122
Before use
●Install a moisture separator/regulator when there is a possibility moisture will
damage the surface to be painted. Install the moisture separator/regulator as
close to the tool as possible.
NOTE: Liquid water occurs naturally
in air lines as a result of
compression. The moisture exiting
near the compressor is warm and
still in a vapor state which allows it
to pass through the moisture
separator. The vapor must travel a
minimum of 5 to 10 feet to cool
down to a liquid to be removed by
the moisture separator. See
Illustration.
●Prior to shipment, this gun was
treated with an anticorrosive agent. Before using this gun make sure that it is
carefully flushed with thinner.
This spray gun has a siphon and pressure feed setting. It is set at the factory for
pressure feed application.
Pressure feed mode is used for fast application of heavy material.
Siphon feed mode is used for applying light and medium bodied paints (stain,
lacquer) to large size jobs such as auto refinishing. Only external mix cap can be
used when in the siphon feed mode.
External mix cap (assembled at factory on spray
gun): The air and material are mixed after leaving
the nozzle. This method is used for fast drying
materials and when a high quality finish is desired.
Internal mix cap (supplied): The air and material
are mixed inside the air cap before being sprayed. This method is used with the
spray gun in the pressure feed mode to spray heavy duty, slow drying material.
Hex Wrench (supplied): used to remove hex screw to convert from pressure feed to
siphon feed mode.
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 EX-
CEED 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 connections for
a weak or worn condition that could render system unsafe. All replacement
components such as hose or fittings must have a working pressure equal
to or greater than system pressure.

5- ENG D27122
TO USE PRESSURE FEED
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.
2. Fill the material cup (a) 3/4 full.
3. Attach material cup (a ) to the gun
securely.
4. Attach air supply line to 1/4 NPT air inlet
(c).
5. Adjust spray pattern.
a. The position of the air cap horns (g) will de-
termine the spray pattern. Loosen air cap (h)
and rotate horns to achieve desired pattern.
Tighten air cap.
6. Turn fluid control knob (b) clockwise until it
stops, do not force. This will shut off the fluid
flow. NOTE: The fluid or density of “fan spray” is controlled by fluid control
knob (b).
7. Adjust air pressure to 40 psi at air compressor.
DO NOT exceed 50 psi.
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 parts results in irregular
spray patterns.
8. Depress spray gun trigger (d) and gradually turn the fluid control knob (b)
counterclockwise until desired fluid flow is reached. Trigger gun quickly, one
second on-off to test pattern.
NEVER point spray gun at self or any other person. Acci-
dental discharge of material may result in serious injury.
NOTE: If gun sprays too fast, decrease the fluid pressure. If too slow, increase the
pressure. Turn fluid control knob (b) counterclockwise to increase, or clockwise to
decrease, the fluid flow.
9. If spraying heavy duty, slow drying material replace external air cap with internal
air cap.
To replace:
a. Remove air cap retainer (h).
b. Remove external air cap and replace with internal air cap (supplied).
c. Replace air cap retainer (h).

Always exercise extreme care when using any solvent or
thinner. Never clean gun near fire, flame, or any source of
heat or sparks. Properly dispose of used cleaning materials.
DO NOT soak entire spray gun in solvent or thinner for a
long period of time as this will destroy lubricants and possi-
bly make motion uneven. NEVER use lye or caustic alkaline solution for
cleaning. Such solutions will attack aluminum alloy parts of gun.
It is important that spray gun be cleaned after daily use. Cleaning is accomplished by
spraying appropriate solvent or thinner through system.
Cleaning
NOTE: Clean gun immediately after use. Paint and other materials dry quickly in
the small passages.
1. Turn off air supply to gun.
2. Loosen the material cup and remove the fluid tube from the material. Hold the
tube over the cup and pull the trigger to allow the paint to drain back into the
cup.
3. Empty material from material cup and replace with a suitable solvent. If using
water based material use mineral spirits to prevent corrosion.
4. Turn air supply on and operate trigger until all material traces have disappeared
and gun is thoroughly clean.
IMPORTANT: Do not immerse the gun in solvent, this will cause damage to the
packings.
NOTE: Always comply with local codes when disposing of solvents.
5. Remove air cap and immerse in a suitable solvent.Use a bristle brush to clean
dried paint and blow it dry with compressed air.
6. Use a wooden toothpick to clean small clogged holes.
IMPORTANT: Make certain air cap and fluid nozzle are kept clean at all times.
DO NOT use hard objects to clean clogged holes. The smallest amount of
damage may cause irregular spray pattern.
7. Wipe gun with a solvent soaked cloth.
Lubrication
Lubrication procedures must be observed after thoroughly cleaning the gun to ensure
effective, high quality performance of spray gun.
1. Lubricate working points with straight mineral oil, or castor oil.
2. Periodically, place a few drops of oil on tapered sections of fluid nozzle to ensure
easy operation of air cap. When spraying water base materials, coat fluid nozzle
inside and outside with straight mineral oil after each use.
MAINTENANCE
TO CONVERT TO SIPHON FEED
1. Remove set screw from canister top and place it in the lower part of gun head
as shown.
2. To operate see steps 2-8 in the “To Use pressure feed” section to continue.
