AVOID PROLONGED
EXPOSURE TO VIBRATION
Some dust created by power sanding,
sawing, grinding, drilling, and other
construction activities contains chemicals
known to cause cancer, birth defects or other
reproductive harm. Some examples of these
chemicals are:
• lead from lead-based paints,
• crystalline silica from bricks
and cement and other masonry
products, and
• arsenic and chromium from
chemically-treated lumber.
Your risk from these exposures varies,
depending on how often you do this type
of work. To reduce your exposure to these
chemicals: work in a well ventilated area,
and work with approved safety equipment,
such as those dust masks that are specially
designed to filter out microscopic particles.

• During cleaning and flushing, solvents can be
forcefully expelled from fluid and air passages.
Some solvents can cause eye injury.
• Be sure all in the area are wearing
impact-resistant eye and face protection.
• Even small projectiles can injure eyes and
cause blindness.
• Air under pressure can cause severe injury.
Always shut off air supply, drain hose of air
pressure and disconnect tool from air supply
when not in use, before changing accessories or
when making repairs. Never direct air at
yourself or anyone else. Whipping hoses can
cause serious injury. Always check for damaged
or loose hoses and fittings. Never use quick
change couplings at tool. They add weight and
could fail due to vibration. Instead, add a hose
whip and connect coupling between air supply
and hose whip, or between hose whip and
leader hose. Do not exceed maximum air inlet
pressure of 43 PSI.
• Always use tool a safe distance from other
people in work area.
• Maintain tools with care. Keep tools clean and
oiled for best and safest performance. Follow
instructions for lubricating and changing
accessories. Wiping or cleaning rags and other
flammable waste materials must be placed in a
tightly closed metal container and disposed of
later in the proper fashion.
• Do not wear loose or ill-fitting clothing; remove
watches and rings.
• Do not over reach. Keep proper footing and
balance at all times. Slipping, tripping and
falling can be a major cause of serious injury
or death. Be aware of excess hose left on the
walking or work surface.
• Do not force tool. It will do the job better and
safer at the rate for which it was designed.
• Do not abuse hoses or connectors. Never
carry tool by the hose or yank hose to
disconnect from air supply. Keep hoses from
heat, oil and sharp edges. Check hoses for weak
or worn condition before each use, making
certain that all connections are secure.
• High sound levels can cause permanent
hearing loss. Protect yourself from noise.
Noise levels vary with work surface.
Wear ear protection.
• When possible, secure work with clamps or
vise so both hands are free to operate tool.
• Repetitive work motions, awkward positions
and exposure to vibration can be harmful to
hands and arms.
• Avoid inhaling dust or handling debris from
work processes which can be harmful to your
health.
• Operators and maintenance personnel must be
physically able to handle the bulk, weight and
power of this tool.
• This tool is not intended for using in explosive
atmospheres and is not insulated for contact
with electric power sources.
• Solvent and coatings can be highly flammable or
combustible especially when sprayed. Adequate
exhaust must be provided to keep air free of
accumulations of flammable vapors.
• Smoking must never be allowed in the
spray area.
• Fire extinguishing equipment must be present in
the spray area.
• Never spray near sources of ignition such as pilot
lights, welders, etc.
• Halogenated hydrocarbon solvents — for
example, methylene chloride — are not
chemically compatible with the aluminum
that might be used in many system components.
The chemical reaction caused by these
solvents reacting with aluminum can become
violent and lead to an equipment explosion.
Guns with stainless steel fluid passages may
be used with these solvents. However,
aluminum is widely used in other spray
application equipment - such as material pumps,
cups and regulators, valves, etc. Check all other
equipment items before use and make sure they
can also be used safely with these solvents.
Read the label or data sheet for the material
you intend to spray. If in doubt as to whether or
not a coating or cleaning material is compatible,
contact your material supplier.
• Sprayed materials may be harmful if inhaled, or
if there is contact with the skin. Adequate
exhaust must be provided to keep the air free
of accumulations of toxic materials. Use a mask
or respirator whenever there is a chance of
inhaling sprayed materials. The mask must be
compatible with the material being sprayed and
its concentration.
- FOLLOW THESE RULES FOR SAFE OPERATION!

9001A: Parts Breakdown & Operating Manual 3 rev. 04/29/06
Never mount oil and water extractor on or near the air compressor.
During compression, air temperature is greatly increased. As the air cools down to room temperature, moisture condenses in the air line, on
its way to the spray gun. Therefore, always mount the oil and water extractor at a point in the air supply system where the compressed air
temperature is lowest.
Drain air lines properly.
Pitch all air lines back towards the compressor so that condensed moisture will flow back into the air receiver where it can be drained off. Each
low point in an air line acts as a water trap. Such points should be fitted with an easily accessible drain. See diagram above.

FOR BEST PERFORMANCE,
PLEASE BE SURE TO DO THE FOLLOWING
BEFORE USING THIS TOOL
•Tighten the gun to the cup securely with the nut and fitting supplied.
•Be sure to have the proper air pressure at the gun to operate. Proper air pressure for this tool should be
35 PSI for lacquer and 43 PSI for enamel.
•Adjust fluid control screw and spray width adjustment screw to your desired pattern before using on production.
•Clean all parts after use.
In normal use, the nozzle wings are
horizontal as shown here. This provides a
vertical fan-shaped pattern which gives
maximum, even material coverage as the
gun is moved back and forth parallel to the
surface being finished.
Spray pattern may be infinitely adjusted
from round to flat.
Set inlet pressure at no more than 43 PSI. For optimum
performance, some materials may spray better at PSI
ratings below 43 PSI. If unsure, always test at PSI ratings before
using on final production. Try spray. If it is too fine, decrease
the air pressure or open fluid control screw. If the spray is too
thick, close the fluid control screw. Regulate the pattern width
and repeat adjustment of spray as needed.

on material and atomizing pressure. For a uniform finish, lap each
stroke over the preceding stroke, making sure the spray is smooth
and wet.
Using the lowest possible atomizing air pressure will reduce over-
spray and provide maximum efficiency.
Proper handling of the gun is essential for obtaining a good finish. The
gun should be held at a right angle to the surface being covered, and
moved parallel with it. For precise control of the gun and material, the
trigger should be released before the end of the stroke.
Hold the gun from 6 to 12 inches away from the surface depending
SPRAY GUN
1. Submerge the front end of the gun in solvent just until the fluid
connection is covered.
2. Paint that has built up on the gun should be removed using a
bristle brush and solvent.
3. Never submerge all of the spray gun in solvent because:
• This will dissolve the lubricant in the leather packings and
on wear surfaces, causing them to dry out and resulting in
difficult operation and faster wear.
• Air passages in the gun will become clogged with
dirty solvent.
4. Using a rag moistened with solvent, wipe down the outside of
the gun.
5. Oil gun daily. Use a drop of lightweight machine oil on:
A. fluid needle packing
B. air valve packing
C. trigger pivot point
See Fig. 1 for Location of Above Points.
6. NOTE: Do not soak rubber o-rings or seals
in paint thinner. O-rings and seals can be
wiped clean with paint thinner but
soaking can cause these items to
deteriorate over time.
7. Caution: Do not use lubricants
which contain silicone. Silicone may
cause defects in the finish application.
AIR NOZZLE, FLUID NOZZLE, AIR VALVE ASSEMBLY
1. All nozzles and needles are made to exact standards. They should
be handled carefully.
2. To clean nozzles, immerse them in solvent until any dried
material is dissolved, then blow them clean.
3. Do not use metal or sharp instrument to probe any of the holes in
the nozzles.
4. Air flow should occur before fluid-flow when the gun is triggered. It
may be necessary to adjust the fluid control screw to make sure
air flows before fluid.
5. Do not alter the gun in any way.
GRAVITY FEED
Turn off air supply. Remove cover of cup. Empty the cup of material.
Clean the cup and cover. Turn on air supply and spray with proper
cleaning solvent. Repeat with clean solvent if necessary. Remove
solvent, disconnect gun, remove air cap and clean. Wipe gun and cup
with rag dampened with solvent.
CAUTION…
To avoid cross-threading, all spray gun parts should be screwed in
hand tight initially. If the parts can not easily be turned by hand ,
be sure you have the correct parts, unscrew, realign, and try again.
NEVER use excessive force in matching parts.
