8. Use eye and ear protection. Always wear ANSI approved impact safety goggles.  
Wear an ANSI approved respirator when working around metal, wood, and chemical  
dusts, mists, paints, oils, sealers, and stains.  
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 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. Avoid unintentional starting. Be sure the switch is in the Off position when not in  
use and before plugging in. Do not carry any tool with your finger on the trigger,  
whether it is plugged in or not.  
12. Stay alert. Watch what you are doing, use common sense. Do not operate any tool  
when you are tired.  
13. 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.  
14. Guard against electric shock. Prevent body contact with grounded surfaces such as  
pipes, radiators, ranges, and refrigerator enclosures.  
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 on prescriptions to determine if your judgment 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, it must  
be of the proper size and type to supply the correct current to the tool without heating  
up. Otherwise, the extension cord could melt and catch fire, or cause electrical  
damage to the tool. This tool requires use of an extension cord of 0 to 10 amps  
capability (up to 50 feet), with wire size rated at 18 AWG. Longer extension cords  
require larger size wire. If you are using the tool outdoors, use an extension cord  
rated for outdoor use (signified by “WA” on the jacket).  
18. Maintenance. For your safety, maintenance should be performed regularly by a  
qualified technician.  
19. 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.  
- An example of these chemicals is lead from lead-based paints.

- Stains, oil-based paints, thinners, sealers, and water-proofers.  
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 respirators that are specially designed  
to filter out microscopic particles. (California Health & Safety Code § 25249.5, et seq. )  
Note: Performance of this tool (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 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.  
Additional Paint Gun Warnings  
1. Although this paint gun is airless, it still puts out paint at a very high pressure. Through  
improper use, paint can be injected through a persons skin, leading to serious injury,  
possibly amputation. If paint is accidentally injected into someone’s skin, contact a  
doctor immediately.  
2. Never point your sprayer at anyone, including yourself. Gloves and clothing don’t offer  
adequate protection from toxic paints, sealers, water-proofers, or stains.  
3. Keep the trigger and the electrical cord plug clean and paint-free.  
4. Never run your sprayer empty. Damage to the unit may occur.  
5. Do not spray asbestos, metallic paints, glazes, red lead, cement, ground chalk,  
abrasive grainy paints containing lime, or bleach through your spray gun. These will  
severely damage the spray gun.  
6. When storing, always coat the unit with a light household oil.  
7. The Sprayer must be plugged into an outlet that is grounded in accordance with all  
local codes and ordinances.  
8. Use caution while spraying on windy days.

Container  
1. Before loading the Container (17) with material, check the viscosity of the material.  
2. Dip the Viscosity Cup into the material, and time how long it takes for the material to  
completely run out of the cup (See FIGURE 1). The longer it takes, the higher the viscosity.  
3. In general, most materials work adequately if the viscosity is  
FIGURE 1  
between 15 and 30 seconds.  
4. If the viscosity is too high, you will have to thin the material to  
use it. Follow the material manufacturer’s instructions for  
thinning each material.  
5. If you thinned materials, retest the viscosity.  
Note: When using a material for the first time, it is  
recommended that you experiment on newspaper attached  
to a vertical surface, testing your spray patterns.
