Clean Sprayer immediately to prevent permanent damage.
Electrical Safety
1. Sprayer plugs must match the outlet. Never modify the plug in any way. Do
not use any adapter plugs with grounded sprayers. Unmodified plugs and
matching outlets will reduce risk of electric shock.
2. Avoid body contact with grounded surfaces such as pipes, radiators, ranges
and refrigerators. There is an increased risk of electric shock if your body
is grounded.
3. Do not expose sprayers to rain or wet conditions. Water entering a sprayer
will increase the risk of electric shock.
4. Do not abuse the cord. Never use the cord for carrying, pulling or
unplugging the sprayer. Keep cord away from heat, oil, sharp edges or moving
parts. Damaged or entangled cords increase the risk of electric shock.
5. When operating a sprayer outdoors, use an extension cord suitable for
outdoor use. Use of a cord suitable for outdoor use reduces the risk of
electric shock.
6. If operating a sprayer in a damp location is unavoidable, use a Ground
Fault Circuit Interrupter (GFCI) protected supply. Use of a GFCI reduces the
risk of electric shock.
Personal Safety
1. Stay alert. Watch what you are doing and use common sense when operating
the tool. Do not use the tool while tired or under the influence of drugs,
alcohol, or medication. A moment of inattention while operating the tool
increases the risk of injury to persons.

Specific Safety Instructions
INJECTION HAZARD!
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 person’s skin, leading
to serious injury, possibly amputation. If paint is
accidentally injected into someone’s skin, contact a
doctor immediately. Do not treat an injection injury
as a simple cut. Injection can lead to amputation
and requires immediate surgical treatment.
2. Do not direct spray at people or animals. Do not place your hand in front of Spray Gun’s nozzle or attempt to deflect paint spray with your hand during use. Gloves and clothing don’t offer adequate protection from toxic paints, sealers, or stains.
3. Do not spray flammable materials in vicinity of open flame or near ignition sources. Motors, electrical equipment, and controls can cause electrical arcs that will ignite a flammable gas or vapor. Do not store flammable liquids or gases in vicinity of this unit.
9. Do not use Paint Sprayer to spray asbestos, metallic paints, glazes, red
lead, cement, ground chalk, abrasive grainy paints containing lime, or bleach.
These will damage the spray gun and void the warranty.
10. Read all of the information concerning coating products and cleaning
solvents. Do NOT use bleach, low-flash naphthalene, acetone, alcohol or
toluene when cleaning Paint Sprayer equipment.
11. Do not use bleach or halogenated hydrocarbon solvents (DCM,
1,1,1trichloroethane, methyl bromine, carbon tetrachloride, and ethyl
iodide). Long term exposure to many chlorinated hydrocarbons through
inhalation can result in liver and kidney toxicity. Exposure of unprotected
skin to the solvents used can cause defatting of the skin resulting in
dermatitis. Methylene chloride and vinyl chloride have also been shown to be
human carcinogens. Some of these solvents are flammable. Welding operations
near the these materials can create phosgene, a highly toxic gas.
4. Do not come into contact with a fluid stream created by a leak in the
paint hose.
5. Do not leave Paint Sprayer pressurized while unattended.
6. Do not clean Spray Gun tip while it is still connected to paint hose.
7. Keep the trigger and the electrical cord plug clean and paint-free.
12. Many spray guns contain aluminum, which reacts strongly to chlorinated
solvents. Contact the solvent or coating manufacturer as needed regarding
potential chemical reactions.
13. Industrial applications must follow OSHA requirements.
14. Spraying hazardous materials may result in serious injury or death. Do
not spray pesticide, acid, corrosive material, fertilizer, or toxic chemicals.
8. Do not run Paint Sprayer while empty. Damage to the unit may occur.

24. Do not use pliers to tighten or loosen high pressure connections.
Sparks from improper grounding
can ignite fumes!
Follow all local regulations regarding
the use of fluid supply containers
and solvent pails used with flushing the Paint
Sprayer. Use only conductive metal pails placed on
a grounded (concrete) surface. Do not place pails
on nonconductive surfaces (such as cardboard or
paper). Ground all metal pails by clamping one end
of a ground wire to the pail and the other end to a
grounded structure (such as a nearby pipe).
Maintain grounding, even when flushing or relieving
pressure from Paint Sprayer into metal pail.
The force of the spray can knock a metal pail over,
so hold down the metal pail and keep the metal
part of the spray gun set against the grounded
metal pail when pressing the spray gun trigger.
26. Maintain labels and nameplates on the sprayer. These carry important safety information. If unreadable or missing, contact Harbor Freight Tools for a replacement.
27. People with pacemakers should consult their physician(s) before use. Electromagnetic fields in close proximity to heart pacemaker could cause pacemaker interference or pacemaker failure.
SAVE THESE INSTRUCTIONS.
Grounding
TO PREVENT ELECTRIC SHOCK AND DEATH FROM INCORRECT GROUNDING WIRE CONNECTION: Check with a qualified electrician if you are in doubt as to whether the outlet is properly grounded. Do not modify the power cord plug provided with the tool. Never remove the grounding prong from the plug. Do not use the tool if the power cord or plug is damaged. If damaged, have it repaired by a service facility before use. If the plug will not fit the outlet, have a proper outlet installed by a qualified electrician.

Grounded Tools: Tools with Three Prong Plugs
3-Prong Plug and Outlet
1. Sprayers marked with “Grounding Required” have a three wire cord and three
prong grounding plug. The plug must be connected to a properly grounded
outlet. If the sprayer should electrically malfunction or break down,
grounding provides a low resistance path to carry electricity away from the
user, reducing the risk of electric shock. (See 3-Prong Plug and Outlet.)
Extension Cords
2. The grounding prong in the plug is connected through the green wire inside
the cord to the grounding system in the sprayer. The green wire in the cord
must be the only wire connected to the sprayer’s grounding system and must
never be attached to an electrically “live” terminal. (See 3-Prong Plug and
Outlet.)
3. The sprayer must be plugged into an appropriate outlet, properly installed
and grounded in accordance with all codes and ordinances. The plug and outlet
should look like those in the preceding illustration. (See 3-Prong Plug and
Outlet.)
1. Grounded sprayers require a three wire extension cord. Double Insulated
sprayers can use either a two or three wire extension cord.
2. As the distance from the supply outlet increases, you must use a heavier
gauge extension cord. Using extension cords with inadequately sized wire
causes a serious drop in voltage, resulting in loss of power and possible
sprayer damage. (See Table A.)
3. The smaller the gauge number of the wire, the greater the capacity of the
cord. For example, a 14 gauge cord can carry a higher current than a 16 gauge
cord. (See Table A.)
4. When using more than one extension cord to make up the total length, make
sure each cord contains at least the minimum wire size required. (See Table
A.)
5. If you are using one extension cord for more than one sprayer, add the
nameplate amperes and use the sum to determine the required minimum cord size.
(See Table A.)
6. If you are using an extension cord outdoors, make sure it is marked with
the suffix “W-A” (“W” in Canada) to indicate it is acceptable for outdoor use.
7. Make sure the extension cord is properly wired and in good electrical condition. Always replace a damaged extension cord or have it repaired by a qualified electrician before using it.
8. Protect the extension cords from sharp objects, excessive heat, and damp or wet areas.
