3. Do not direct spray at people or animals.
4. Read all of the information concerning
coating products and cleaning solvents.
Do not use chlorinated solvents
(e.g. 1-1-1 trichloroethylene and
dichloromethane, also known as
methylene chloride) to clean spray guns.
Many spray guns contain aluminum,
which reacts strongly to chlorinated solvents.
Contact the solvent or coating manufacturer as
needed regarding potential chemical reactions.
5. Risk of injection – Do not point spray gun at any
person or any part of the body. In case of skin
injection, seek medical attention immediately.
6. Spraying hazardous materials may result in serious
injury or death. Do not spray pesticide, acid,
corrosive material, fertilizer, or toxic chemicals.
7. Paints and solvents may be harmful or fatal if
swallowed or inhaled. Avoid prolonged skin

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.
Double Insulated Tools: Tools with Two prong plugs
Figure A: Outlets for 2-prong plug
1. Tools marked “Double Insulated” do not
require grounding. They have a special
double insulation system which satisfies OSHA
requirements and complies with the applicable
standards of Underwriters Laboratories, Inc.,
the Canadian Standard Association,
and the National Electrical Code.
2. Double insulated tools may be used in
either of the 120 volt outlets shown in the
preceding illustration. (See Figure A.)
3. This appliance has a polarized plug (one blade is
wider than the other). This plug will fit in a polarized
outlet only one way. If the plug does not fit fully in
the outlet, reverse the plug. If it still does not fit,
contact a qualified electrician to install the proper
outlet. Do not change the plug in any way.
Extension Cords
1. Grounded tools require a three wire extension cord.
Double Insulated tools 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 tool 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 tool, add the nameplate amperes
and use the sum to determine the required
minimum cord size. (See Table A.)

1. 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.
2. 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.
3. Protect the extension cords from sharp objects,
excessive heat, and damp or wet areas.
