Cluttered or dark areas invite acci-
dents.
Do not operate power tools in b.
explosive atmospheres, such as in
the presence of ammable liquids,
gases or dust. Power tools create
sparks which may ignite the dust or

Distractions can cause you to lose
control.
Electrical safety2.
Power tool plugs must match the a.
outlet. Never modify the plug in
any way. Do not use any adapter
plugs with grounded power tools.

lets will reduce risk of electric shock.
Avoid body contact with grounded b.
surfaces such as pipes, radiators,
ranges and refrigerators. There is
an increased risk of electric shock if
your body is grounded.
Do not expose power tools to rain c.
or wet conditions. Water entering
a power tool will increase the risk of
electric shock.
Do not abuse the Power Cord. d.
Never use the Cord for carrying,
pulling or unplugging the power
tool. Keep Cord away from heat,
oil, sharp edges or moving parts.
Damaged or entangled cords in-
crease the risk of electric shock.
When operating a power tool out-e.
doors, use an Extension Cord (not
included) suitable for outdoor use.
Use of a Cord suitable for outdoor
use reduces the risk of electric shock.
Always use a Ground Fault Circuit f.
Interrupter (GFCI) protected outlet.
Use of a GFCI reduces the risk of
electric shock.

Use the correct power tool for your
application. The correct power tool
rate for which it was designed.
Do not use the power tool if the b.
Power Switch does not turn it on
and off. Any power tool that cannot
be controlled with the Switch is dan-
gerous and must be repaired.
Disconnect the Power Cord Plug c.
from the power source before mak-
ing any adjustments, changing ac-
cessories, or storing power tools.
Such preventive safety measures
reduce the risk of starting the power
tool accidentally.
Store idle power tools out of the d.
reach of children and do not allow
persons unfamiliar with the power
tool or these instructions to oper-
ate the power tool.
Power tools are dangerous in the
hands of untrained users.
Maintain power tools. Check for e.
misalignment or binding of moving
parts, breakage of parts and any
other condition that may affect the
power tool’s operation.
If damaged, have the power tool
repaired before use.
Many accidents are caused by poorly
maintained power tools.
Use the power tool and its f.
accessories in accordance with
these instructions, taking into
account the working conditions
and the work to be performed.
Use of the power tool for operations
different from those intended could
result in a hazardous situation.
Service5.
Have your power tool serviced by a.
a qualied repair person using
only identical replacement parts.
This will ensure that the safety of the
power tool is maintained.

GROUNDING
TO PREVENT
ELECTRIC SHOCK
AND DEATH FROM
INCORRECT GROUNDING
WIRE CONNECTION:
Check with a qualied
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 t the Outlet, have a
proper Outlet installed by a
qualied electrician.
SKU 66745 For technical questions, please call 1-800-444-3353. Page 9
Grounded Tools: Tools with Three
Prong Plugs
Tools marked with “Grounding Re-1.
quired” have a three wire cord and
three prong grounding plug. The
plug must be connected to a properly
grounded outlet. If the tool 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.)
The grounding prong in the plug is 2.
connected through the green wire in-
side the cord to the grounding system
in the tool. The green wire in the cord
must be the only wire connected to
the tool’s grounding system and must
never be attached to an electrically
“live” terminal. (See 3-Prong Plug
and Outlet.)
The tool must be plugged into an 3.
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.)
Double Insulated Tools: Tools
with Two Prong Plugs
Tools marked “Double Insulated” do 1.
not require grounding. They have
a special double insulation system
and complies with the applicable
standards of Underwriters Labora-
tories, Inc., the Canadian Standard
Association, and the National Electri-
cal Code. (See Outlets for 2-Prong
Plug.)
Double insulated tools may be used 2.
in either of the 120 volt outlets shown
in the preceding illustration. (See
Outlets for 2-Prong Plug.)
EXTENSION CORDS
Grounded tools require a three wire 1.
extension cord. Double Insulated
tools can use either a two or three
wire extension cord.
As the distance from the supply outlet 2.
increases, you must use a heavier
gauge extension cord. Using exten-
sion cords with inadequately sized
wire causes a serious drop in voltage,
resulting in loss of power and pos-
sible tool damage.
(See Table A.)
SKU 66745 For technical questions, please call 1-800-444-3353. Page 10
The smaller the gauge number of the 3.
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.)
When using more than one exten-4.
sion cord to make up the total length,
make sure each cord contains at
least the minimum wire size required.
(See Table A.)
If you are using one extension cord 5.
for more than one tool, add the
nameplate amperes and use the sum
to determine the required minimum
cord size. (See Table A.)
If you are using an extension cord 6.
outdoors, make sure it is marked with

use.

WARNING! • Never attempt to stop
your hands, body, gloves, rags, etc.
If there are no leaks in the system,
squeeze the Trigger and continue
spraying until no water comes out of
the Spray Gun.
Turn off the power, and continue

IMPORTANT:2. Do not run the Sprayer
dry for more than 30 seconds. Doing
so can damage the Pump Packing.
NOTE: 3. Before spraying the actual
workpiece, it is recommended to test
spray on scrap material.
Unlock the Trigger Safety Lock (18B) 4.
by pulling back on the tab of the Lock
and turning it to either side.
Face the Spray Tip toward the 5.
item to be painted. (See bottom photo

Painting Tips
Successful spray painting is a skill 1.
which requires knowledge of your
equipment, familiarity with your paint
materials and experience.
Differences in paints, work materials
and environmental conditions make
every painting task unique. For best
results, practice with your painting
mixture on scrap material before
beginning to paint your workpiece.

It is critical that the surface be
properly prepared before painting.
-
factory painted surface if the original
surface is dirty, rough, or wet.
Properly mask your paint surface
want to paint. Use drop cloths or
-
In most cases, it is best to move the 2.
paint spray from side to side, overlap-
ping the previous paint. To paint in
this way, the spray pattern should be
set to vertical.
It is important to prevent excess
paint at the beginning and end of
each stroke. Holding the Spray
Gun away from the workpiece,
squeeze the Trigger to start the
spray. Then move the Spray Gun
in to within 14-16 inches of the
workpiece. Move the Spray Gun
smoothly across the workpiece,
keeping a consistent distance. At
the end of each stroke, pull the
Spray Gun away from the work-
piece as you release the Trigger.
As you work, observe the way the
paint accumulates on the work
surface. It is more important to
maintain a good paint surface than
to form an opaque (thick) paint coat.
You can always apply a second coat
to get the coverage you want. If
the surface is ruined, however, you
will have to start over with surface
preparation.
If the surface does not smooth out
in a few seconds after applying the
paint, your paint mixture is probably
too thick. Thin your paint slightly
and test on scrap material. If the
paint goes on very thin and threat-
ens to run, stop spraying immediate-
ly. Add more paint to your mixture
to thicken the paint. Test on scrap
material before resuming work.
