Unmodified plugs and matching out-
lets will reduce risk of electric shock.
mask/respirator. Safety equipment
such as non-skid safety shoes, hard
hat, or hearing protection used for
appropriate conditions will reduce
personal injuries.
b.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.
c.Prevent unintentional starting.
Ensure the Power Switch (33) is in
the off-position before connecting
to the power source, picking up or
carrying the tool. Carrying power
tools with your finger on the Power
Switch or energizing power tools that
have the Power Switch on invites ac-
cidents.
c.do not expose power tools to rain
or wet conditions. Water entering
a power tool will increase the risk of
electric shock.
d.do not abuse the Power Cord (34).
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.
d.Remove any adjusting key or
wrench before turning the power
tool on. A wrench or a key left at-
tached to a rotating part of the power
tool may result in personal injury.
e.When operating a power tool out-
doors, use an extension cord suit-
able for outdoor use. Use of a cord
suitable for outdoor use reduces the
risk of electric shock.
e.do not overreach. Keep proper
footing and balance at all times.
This enables better control of the
power tool in unexpected situations.
f. dress properly. do not wear loose
clothing or jewelry. Keep your
hair, clothing and gloves away
from moving parts. Loose clothes,
jewelry or long hair can be caught in
moving parts.
f. If operating a power tool 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.
4. Power tool use and care
3. Personal safety
a.do not force the power tool. use
the correct power tool for your ap-
plication. The correct power tool will
do the job better and safer at the rate
for which it was designed.
a.Stay alert, watch what you are do-
ing and use common sense when
operating a power tool. do not use
a power tool while you are tired
or under the influence of drugs,
alcohol or medication. A moment
of inattention while operating power
tools may result in serious personal
injury.
b.do not use the power tool if the
Power Switch (33) does not turn
it on and off. Any power tool that
cannot be controlled with the Power
Switch is dangerous and must be
repaired.
b.use safety equipment. Always
wear ANSI-approved safety impact
goggles and NIOSH-approved dust

c.disconnect the Power Cord (34)
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.
SPECIFIC SAFETY
WARNINgS
1. Maintain labels and nameplates
on the Paint Sprayer. These carry
important safety information. If un-
readable or missing, contact Harbor
Freight Tools for a replacement.
d.Store idle power tools out of the
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.
2. Avoid unintentional starting. Pre-
pare to begin work before turning on
the Paint Sprayer.
3. For your safety, maintenance
should be performed regularly by
a qualified service technician. The
Paint Sprayer and its accessories
must be thoroughly cleaned after
every use.
e.Maintain power tools. Check for
misalignment or binding of moving
parts, breakage of parts and any
other condition that may affect the
power tool’s operation. If dam-
aged, have the power tool repaired
before use. Many accidents are
caused by poorly maintained power
tools.
4. Do not spray near open flames,
pilot lights, stoves, heaters, or any
other heat source. Most solvents
and coatings are highly flammable,
particularly when sprayed. do not
smoke while spraying.
f. Keep the power tool clean. Improp-
er cleaning of the Paint Sprayer and
its accessories is a common reason
for the Spray Gun to jam or not per-
form properly.
5. Read all of the information con-
cerning coating products and
cleaning solvents. Chlorinated sol-
vents (i.e., trichlorethylene and meth-
ylene chloride) can chemically react
with aluminum and may explode.
Many Paint Sprayers contain alumi-
num. If you have any doubt about
potential chemical reactions contact
the solvent or coating manufacturer.
g.use the power tool, accessories
and tool bits etc. in accordance
with these instructions, taking into
account the working conditions
and the work to be performed. Use
of the power tool for operations differ-
ent from those intended could result
in a hazardous situation.
6. Materials used when painting or
cleaning may be harmful or fatal
if inhaled or swallowed. Only use
in an area with adequate ventilation.
Use a NIOSH-approved dust mask
or respirator when painting or using
solvents.
5. Service
a.Have your power tool serviced by
a qualified repair person using
only identical replacement parts.
This will ensure that the safety of the
power tool is maintained.

cur.
Your risk from these exposures var-
ies, 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
those dust masks that are specially
designed to filter out microscopic
particles. (California Health & Safety
Code § 25249.5, et seq.)
11. Spraying hazardous materials may
result in death or serious injury.
Do not spray pesticides, acids, cor-
rosive materials, fertilizers, and toxic

proximity to heart pacemaker could
cause pacemaker interference or
pacemaker failure. In addition, peo-
ple with pacemakers should:
• Avoid operating alone.
17. The warnings, precautions, and
instructions discussed in this in-
struction 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.
• Do not use with power switch locked
on.
• Properly maintain and inspect to

4. Plug the Power Cord (34) into the
nearest 120 volt, grounded, electrical
outlet. Then turn the Power Switch
(33) to its “ON” position.
Work Piece and Work Area Set up
1. Designate a work area that is clean
and well-lit. The work area must not
allow access by children or pets to
prevent injury and distraction.
(See Figure A, on page 8.)
5. Adjust the air pressure during op-
eration with the Trigger (6) and the
Air Control Lever (13). Turn the Air
Control Lever clockwise to provide
less air to the Spray Gun. Turn the
Air Control Lever counterclockwise
to provide more air to the Spray Gun.
(See Figure A, on page 8.)
2. Route the Power Cord (34) along a
safe route to reach the work area
without creating a tripping hazard
or exposing the Power Cord to pos-
sible damage. The Power Cord must
reach the work area with enough
extra length to allow free movement
while working.
6. Set up a piece of scrap material to
practice on. While practicing on the
scrap material, check to see that the
paint/fluid you are spraying has the
appropriate consistency. If it appears
too thick, add a very small amount of
thinner (not included).
3. Secure loose workpieces using a vise
or clamps (not included) to prevent
movement while working.
4. There must not be hazardous ob-
jects, such as utility lines or foreign
objects, nearby that will present a
hazard while working.
7. To change the direction of the fan
from horizontal to vertical, loosen the
Air Cap Screw (5) and turn the Air
Nozzle (4) 90 degrees. After the ad-
justment, tighten the Air Cap Screw.
(See Figure B.)

9. After setting up a piece of scrap mate-
rial, squeeze the Trigger (6) in short
bursts while turning the Fluid Control
Screw (19) counterclockwise and
observe the pattern for consistency.
Too much air may cause the spray
to come out too fine. Reduce the air
pressure or allow more paint/fluid to
come out by opening the Fluid Control
Screw. If the spray appears too thick
(you see globs of paint/fluid), close
down the Fluid Control Screw slowly,
checking the mixture after each ad-
justment. (See Figure d.)

2. To ensure you don’t allow paint to build
up, start moving the Spray Gun before
you squeeze the Trigger (6). When
you are finished spraying, release the
Trigger before you stop moving the
Spray Gun. Doing so will eliminate
distinct overlaps, producing a blended
(feathered) affect. (See Figure F.)

3. NOTE: The speed of the stroke, the
adjustment of the Fluid Control Screw
(19), and the distance from the work-
piece will determine how much paint/
fluid is being applied. To get the best
results, try to apply two thin coats of
paint/fluid versus one thick coat.
TECHNIQuES
1. Always keep the Spray Gun at right
angles to the workpiece. Pull the
Trigger (6) slowly and move the Spray
Gun in parallel strokes to the object
being painted. Keep the distance
from the object being painted at 6” to
9”. This may slightly differ depending
on the flow adjustment and the paint/
fluid being sprayed. Do not stop the
Spray Gun movement while spraying.
4. When finished, thoroughly clean out
the Paint Sprayer and its accessories.
