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.

10. Never point a Spray gun at people  
or animals. Serious injury could oc-  
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  
chemicals.

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  
avoid electrical shock.

2. The grounding prong in the Plug is  
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.)  
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  
(34) 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.  
3. The tool 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

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.)  
5. Cover all furniture, decorations,  
floors, walls, etc. not intended to be  
painted.

1. Mix and thin the paint or other fluid  
thoroughly according to the manufac-  
turer’s directions.  
2. Carefully strain the paint/fluid through  
a paint strainer or piece of cheese  
cloth.  
8. To set the pattern size specific to the  
job, use the Fluid Control Screw (19).  
Turn it clockwise for a round pattern.  
Turn the Screw counterclockwise (all  
the way open) to flatten the pattern.  
(See Figure C, next page.)  
3. Fill the Cup (27) to approximately  
3/4 full. Then attach the Cup to the  
Spray Gun. (See Figure A, on page

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.

Procedures not specifically  
explained in this manual  
must be performed only by a  
qualified technician.  
3. SOLVENT SELECTION: Always fol-  
low the paint/fluid manufacturer’s rec-  
ommendations for cleaning, solvent  
type, and disposing of used solvent.  
TO PREVENT  
SERIOuS INjuRY  
FROM ACCIdENTAL  
• Oil-based paints/fluids: Use mineral  
spirits.  
OPERATION:  
• Latex (water-based) paints/fluids:  
Use warm, soapy water.  
Turn the Power Switch (33) of  
the Paint Sprayer to its “OFF”  
position and unplug the tool  
from its electrical outlet  
before performing any  
inspection, maintenance, or  
cleaning procedures.  
IMPORTANT: Do not use min-  
eral spirits on latex (water-based)  
paints/fluids or the mixture will  
congeal, making it very difficult to  
remove.  
• If a flammable solvent is used, ad-  
here to the following: (1) Follow all  
of the solvent manufacturer’s clean  
up instructions and safety precau-  
tions at all times. (2) If collecting  
flushed solvents into a metal con-  
tainer, transfer into a larger non-  
metal container, and flush the metal  
container.  
TO PREVENT SERIOuS  
INjuRY FROM TOOL  
FAILuRE:  
do not use damaged  
equipment. If abnormal noise  
or vibration occurs, have the  
problem corrected before  
further use.  
4. AFTER uSE:  
Inspection, Maintenance, and  
Cleaning  
Empty the Cup (27), and clean it  
with solvent for oil-based paint/fluid  
or soap and water for water-based  
paint/fluid.  
1. BEFORE EACH uSE, inspect the  
general condition of the Paint Sprayer  
and its accessories. Check for loose  
screws, misalignment or binding of  
moving parts, cracked or broken  
parts, damaged electrical wiring/air  
hose, and any other condition that  
may affect its safe operation.  
Fill the Cup (27) with solvent (or  
water) and spray it through the  
Gun into a container while shaking  
the Gun. Once the Cup is empty,  
repeat the process until the solvent/  
water comes out clean.  
2. IMPORTANT: The Spray Gun must  
be cleaned immediately after each  
use. Improper cleaning is a com-  
mon reason for the Spray Gun not  
to operate properly. Materials dry  
Turn the Power Switch (33) to its  
“OFF” position and disconnect from  
the electrical outlet. After discon-  
necting, be aware that air pressure
