HAZARD
Risk of flying objects
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.
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.
Prolonged exposure to air spray can result in per-
manent damage to hearing.
Always wear hearing protection when operating
spray equipment.
HAZARD
Risk of injection
WHAT COULD HAPPEN
HOW TO PREVENT IT
Spray guns operate at pressures and velocities
high enough to penetrate human and animal flesh,
which could result in amputation or other serious
injury.
Never place hands in front of nozzle.
Direct spray away from self and others.
! See a physician immediately!

GENERAL INFORMATION
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 assume system pressure is zero!
TO AVOID CREATING AN EXPLOSIVE ATMOSPHERE, WORK ONLY
IN WELL VENTILATED AREAS.
USE OF A FACE MASK IS RECOMMENDED TO PREVENT
HINHALATION OF TOXIC MATERIAL.

Prior to daily
operation, make
certain that all connections and fittings
are secure. Check hose and all con-
nections for a weak or worn condition
that could render system unsafe. All
replacement components such as

pressure equal to or greater than
system pressure.

Prior to shipment, this gun was treated with an
anticorrosive agent. Before using this gun make sure that it is
carefully flushed with thinner.
1. The position of the air cap (H) horns will determine the
spray pattern. Loosen (G) air cap and rotate horns to
achieve desired pattern. Tighten air cap.
2. Attach material cup to the gun. NOTE: The (F) material filter
supplied is optional to protect against contaminants and
small particles. See parts list for material filter orientation.
Horizontal position
3. Attach air supply line to 1/4 NPS air inlet.
NEVER point spray gun at self or any
other person. Accidental discharge of
material may result in serious injury.
Vertical position
4. Adjust air pressure at air compressor.
DO NOT exceed 100 psi.
5. Depress spray gun trigger fully to spray material. NOTE: Depressing trigger partially will
cause only air to be released.
Adjust spray gun:
a. 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.
b. Width of “fan spray” is governed by (B) pattern adjustment knob. Turn knob counterclock-
wise to increase, or clockwise to decrease, air flow.
c. Air quantity is controlled by (C) air-volume control knob. Turn knob counterclockwise to
increase, or clockwise to decrease, the air flow.
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.

MAINTENANCE
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 possibly make
motion uneven. NEVER use lye or caustic alkaline solution for cleaning. Such solu-
tions 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. Wipe exterior of spray gun with solvent soaked
cloth or use cleaning brush(s) provided to remove any accumulated material.
Cleaning
(a) Empty material from gravity feed cup and replace with a suitable solvent.
(b) Operate trigger until all material traces have disappeared and gun is thoroughly clean.
(c) Clean air cap with brush.
IMPORTANT: Make certain air cap and fluid nozzle are kept clean at all times. If necessary,
remove these two components and soak them in solvent. DO NOT use hard objects to clean
clogged holes. The smallest amount of damage may cause irregular spray pattern.
NOTE: If fluid nozzle is to be removed for thorough cleaning, squeeze trigger to prevent dam-
age of fluid needle tip when unscrewing nozzle.
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.
3. Outer diameter of needle sleeve of fluid needle assembly must be lubricated occasionally
with straight mineral oil.
Change or Replace nozzle set
When changing nozzle set, make sure the complete nozzle set is exchanged. A set includes
an air cap, fluid nozzle, and fluid needle. NOTE: Assemble fluid nozzle before putting in fluid
needle.
