SAFETY OPERATION MAINTENANCESETUP
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.
 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.
2. Dress properly. Do not wear loose clothing
or jewelry. Contain long hair. Keep hair,
clothing, and gloves away from moving parts.
Loose clothes, jewelry, or long hair increases
the risk of injury to persons as a result
of being caught in moving parts.
 Avoid unintentional starting. Be sure the
trigger is off before connecting to the
power supply. Do not carry the sprayer with
your finger on the trigger or connect the sprayer
to the power supply with the trigger on.
4. Do not overreach. Keep proper
footing and balance at all times.
Proper footing and balance enables better
control of the tool in unexpected situations.

Specific Safety Instructions
1. 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.
 Do not spray flammable materials in vicinity
of open flame or near ignition sources.
Motors, electrical equipment, and controls

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.
12. Many spray guns contain aluminum,
which reacts strongly to chlorinated solvents.
Contact the solvent or coating manufacturer as
needed regarding potential chemical reactions.
 Industrial applications must follow
OSHA requirements.

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.

Clean Sprayer immediately to prevent permanent damage.
SAFETYOPERATIONMAINTENANCE SETUP
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.)
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.)
 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.)
Extension Cords
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.)
 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.
