7. Dress properly. Do not wear loose clothing or jewelry as they can be caught in
moving parts. Protective, electrically nonconductive clothes and nonskid footwear are
recommended when working. Wear restrictive hair covering to contain long hair.
8. Use eye and breathing protection. Always wear ANSI-approved impact safety
goggles. Wear an ANSI-approved respirator when spraying.
9. Do not overreach. Keep proper footing and balance at all times. Do not reach over or
across running machines.
10. Maintain tools with care. Keep tools clean for better and safer performance. Follow
instructions for lubricating and changing accessories. Inspect tool cords and hoses
periodically and, if damaged, have them repaired by an authorized technician. The
handles must be kept clean, dry, and free from oil and grease at all times.
11. Disconnect power. When not in use disconnect from compressor.
12. Remove adjusting keys and wrenches. Check that keys and adjusting wrenches
are removed from the tool or machine work surface before plugging it in.
13. Avoid unintentional starting. Do not carry any tool with your finger on the trigger,
whether it is plugged in or not.
14. Stay alert. Watch what you are doing, use common sense. Do not operate any tool
when you are tired.
15. Check for damaged parts. Before using any tool, any part that appears damaged
should be carefully checked to determine that it will operate properly and perform its
intended function. Check for alignment and binding of moving parts; any broken parts
or mounting fixtures; and any other condition that may affect proper operation. Any
part that is damaged should be properly repaired or replaced by a qualified
technician. Do not use the tool if any switch does not turn On and Off properly.
16. Guard against electric shock. Prevent body contact with grounded surfaces such as
pipes, radiators, ranges, and refrigerator enclosures.
17. Replacement parts and accessories. When servicing, use only identical
replacement parts. Use of any other parts will void the warranty.
18. Do not operate tool if under the influence of alcohol or drugs. Read warning
labels on prescriptions to determine if your judgment or reflexes are impaired while
taking drugs. If there is any doubt, do not operate the tool.
19. Use proper size and type extension cord. If an extension cord is required, it must be
of the proper size and type to supply the correct current to the air compressor without
heating up. Otherwise, the extension cord could melt and catch fire, or cause electrical
damage to the air compressor. Check air compressor manual.
20. Maintenance. For your safety, maintenance should be performed regularly by a
qualified technician.
21. Keep aware of air hoses. Be careful not to trip over air hoses while working. Check
air connections periodically.

22. Do not operate Spray Gun near open flames, pilot lights, heaters, or any other
heat source. Make sure you have adequate ventilation. Most solvents and paints
are extremely flammable, especially when sprayed. Never smoke cigarettes in the
same room you are working in.
23. Read labels on cleaning solvents and paint coatings. Chlorinated solvents such as
111-Trichloroethane and Methylene Chloride (also known as methyl-chloride) can
chemically react with aluminum and may explode. Many paint sprayers contain
aluminum. Contact solvent manufacturer or paint supplier if your are in doubt.
24. Paints and solvents may be harmful or fatal if swallowed or inhaled. Always use
a respirator when spraying. Avoid prolonged skin contact with solvents or paints as
they will irritate skin. After contact, immediately wash off exposed area with hot,
soapy water.
25. Check all Spray Gun Seals and Air Connection. Before use, make sure the
Lid (#23) is fully tightened to the Cup (#19). Make sure the air hose is securely
fastened to the Gun Body (#13).
Note: Performance of the compressor (if powered by line voltage) may vary depending
on variations in local line voltage. Extension cord usage may also affect tool perfor-
mance.
Warning:The warnings, cautions, and instructions discussed in this instruction manual
cannot cover all possible conditions and situations that may occur. It must be under-
stood by the operator that common sense and caution are factors which cannot be
built into this product, but must be supplied by the operator. Additionally, read all of
the warnings and instructions provided in the instruction manual of the air
compressor you will be using.
WARNING: This product contains or, when used, produces a chemical known to the
State of California to cause cancer and birth defects or other reproductive harm.

with the available adjustments, prior to use.
1. Remove the Lid (#23) on the Cup (#19) and add no more than 10 ounces of paint.
Replace the Lid (#23).
2. Connect the air hose to the Air Connector (#40) and set the pressure to 50 PSI. Do
not exceed 70 PSI.
3. Squeeze the Trigger (#31) to test the pattern.
4. Spray from a distance of approximately four to eight inches while keeping the Spray
Gun perpendicular to the ground.
5. Maintain your distance as you evenly move from side to side. Do not fan or arc the
Spray Gun or the paint will apply unevenly.
6. When you finish spraying, release the Trigger (#31), and disconnect the air hose.
7. Empty the Cup (#19). Never store the Cup (#19) with paint in it.

Open it slowly and carefully.
Adjustments
1. You can fine tune the air pressure by slowly turning the Air Adjustment Screw Valve
Assy. (#A5). You may also adjust the pressure with the air compressor. Make sure
you do not exceed the recommended 70 PSI.
2. You can adjust the amount of fluid coming through the gun with the Fluid Control
Knob (#18). Loosen the Fluid Control Knob Lock (#17), make the adjustment, and

IMPORTANT: Before using for the first time, the spray gun must be cleaned
using a solvent based thinner. If not removed, the red oil used by the
manufacturer for testing and corrosion protection may contaminate paint.
IMPORTANT: The Spray Gun must be cleaned immediately after use.
Improper cleaning is a common reason for the Spray Gun not to work.
Maintenance
Cleaning (Gun should be attached to compressor to complete the cleaning process)
Warning!! Do not use paint strippers on this unit as they will damage the aluminum. Never
allow the unit to lay on it’s side while paint is in the Cup (#19).
1. Empty paint from Cup (#19) and add small amount of clean solvent. Replace Lid (#23)
and shake Cup (#19) vigorously. At the lowest possible pressure, spray out the solvent into a
waste bucket (make sure you are wearing respirator and eye protection).
2. Empty Cup (#19) of remaining solvent and repeat the process until the Cup (#19) solvent
appears clean and free of the paint.
3. Disconnect air supply. Remove surplus solvent and wipe the Cup (#19) clean with a lint
free cloth.
Note: The Cup (#19) may be fully immersed in solvent for no more than 24 hours if needed.
4. Remove the Air Cap (#3) and the Ring (#4). Remove the Brass Ring (#5) and unscrew
the Fluid Nozzle (#6), and remove it. Use the Brush (#1) to clean the Paint Needle (#14)
with solvent. When replacing the Fluid Nozzle (#6), do not overtighten. Overtightening of the
Fluid Nozzle (#6) will result in leakage. Unscrew the Fluid Control Knob Lock (#17) and
remove the Fluid Control Knob (#18). Use the Brush (#1) to clean the gun body
opening that the Fluid Control Knob (#18) fits in, and clean all of the parts.
Reassemble gently. Parts may be damaged if forced into place.
Note: Always dispose of paints and solvents properly. Consult the local hazardous
waste authority for proper disposal procedures and sites.
