Safety Warnings and Precautions
WARNING: When using tool, basic safety precautions should always be followed to
reduce the risk of personal injury and damage to equipment.
Read all instructions before using this tool!
1. Keep work area clean. Cluttered areas invite injuries.
2. Observe work area conditions. Do not use machines or power tools in damp or wet
locations. Don’t expose to rain. Keep work area well lit. Do not use air tools in the
presence of flammable gases or liquids.
3. Keep children away. Children must never be allowed in the work area. Do not let
them handle machines, tools, extension cords, or air hoses.
4. Store idle equipment. When not in use, tools must be stored in a dry location to inhibit
rust. Always lock up tools and keep out of reach of children.
5. Use the right tool for the job. Do not attempt to force a small tool or attachment to do
the work of a larger industrial tool. There are certain applications for which this tool
was designed. It will do the job better and more safely at the rate for which it was
intended. Do not modify this tool and do not use this tool for a purpose for which it was
not intended.

Troubleshooting section at end of manual.
6. 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.
7. Use eye and ear protection. Always wear ANSI approved impact safety goggles.
Always wear an ANSI approved dust mask or respirator when using this Spray
Gun.
8. Do not overreach. Keep proper footing and balance at all times. Do not reach over or
across running machines or air hoses.
9. Maintain tools with care. Keep tools clean for better and safer performance. Follow
instructions for lubricating and changing accessories. Inspect tool cords and air hoses
periodically and, if damaged, have them repaired by an authorized technician. The
handle must be kept clean, dry, and free from oil and grease at all times.
10. Disconnect air supply. Release any built-up pressure and disconnect air hose when
not in use, when changing accessories, and/or during maintenance.
11. Remove adjusting wrenches. Check that adjusting wrenches are removed from the
tool before attaching to the air source.
12. Avoid unintentional starting. Be sure the trigger is in the Off position when not in use
and before attaching to the air source. Do not carry any tool with your finger on the
trigger, whether it is attached to the air compressor or not.
13. Stay alert. Watch what you are doing, use common sense. Do not operate any tool
when you are tired.
14. 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 the trigger does not operate properly.
15. Replacement parts and accessories. When servicing, use only identical replacement
parts. Use of any other parts will void the warranty. Only use accessories intended for
use with this tool. Approved accessories are available from Harbor Freight Tools.
16. Do not operate tool if under the influence of alcohol or drugs. Read warning labels
if taking prescription medicine to determine if your judgement or reflexes are impaired
while taking drugs. If there is any doubt, do not operate the tool.
17. Use proper size and type extension cord. If an extension cord is required for the
compressor, it must be of the proper size and type to supply the correct current to the
compressor without heating up. Otherwise, the extension cord could melt and catch

fire, or cause electrical damage to the compressor. Check your compressor’s manual
for the appropriate size cord.
18. Maintenance. For your safety, maintenance should be performed regularly by a qualified
technician and the unit must be thoroughly cleaned out after every use. Improper
cleaning of the Spray Gun is a common reason for the Spray Gun to jam or not
perform properly.
19. Compressed air only. Never use combustible gas as a power source. Never exceed
the recommended operating pressure of the any of the parts (i.e. hoses, fittings, gun)
of the Sprayer system.
20. Do not spray near open flames, pilot lights, stoves, heaters, the air compressor,
or any other heat source. Most solvents and coatings are highly flammable, particularly
when sprayed. Maintain a distance of at least 25 feet from the air compressor. If
possible, locate the air compressor in a separate room. Do not smoke while spraying.
21. Read all of the information concerning coating products and cleaning solvents.
Chlorinated solvents (e.g. 1-1-1 Trichlorethylene and Methylene Chloride, also known
as methyl chloride) can chemically react with aluminum and may explode. Many paint
sprayers contain aluminum. If you have any doubt about potential chemical reactions,
contact the solvent or coating manufacturer.
22. Materials used when painting or cleaning may be harmful or fatal if inhaled or
swallowed. Only use in an area with adequate ventilation. Use a respirator or mask
when painting or using cleaning solvents.
23. Never release the sprayer lid while the cup is pressurized.
24. Industrial applications must follow OSHA requirements.
25. Never point a spray gun at a person or animal. Serious injury could occur.
26. Spraying hazardous materials may result in serious injury or death. Do not spray
pesticides, acids, corrosive materials, fertilizers, and toxic chemicals.
27. WARNING: The brass components of this product contain lead, a chemical known to
the State of California to cause birth defects (or other reproductive harm).
(California Health & Safety Code § 25249.5,
28. Do not exceed the maximum of 35 PSI for these spray guns.
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 performance.
WARNING: The warnings, cautions, and instructions discussed in this instruction manual
cannot cover all possible conditions and situations that may occur. It must be understood by the operator that common sense and caution are factors which cannot be
built into this product, but must be supplied by the operator.
