9.	

Maintain tools with care. Keep tools clean for better and safer performance. Follow
instructions for lubricating and changing accessories. Inspect tool cords and air hoses
periodically and, if damaged, have them repaired by an authorized technician. The
handle must be kept clean, dry, and free from oil and grease at all times.

10.	

Disconnect air supply. Disconnect air hose when not in use, when changing
accessories, and during maintenance.

11.	

Remove adjusting wrenches. Check that adjusting wrenches are removed from the
tool before attaching to the air source.

12.	

Avoid unintentional starting. Be sure the trigger is in the Off position when not in
use and before attaching to the air source. Do not carry any tool with your finger on
the trigger, whether it is attached to the air compressor or not.

13.	

Stay alert. Watch what you are doing, use common sense. Do not operate any tool
when you are tired.

14.	

Check for damaged parts. Before using any tool, any part that appears damaged

of the Sprayer system.
20.	

Do not spray near open flames, pilot lights, stoves, heaters, the air compressor, or
any other heat source. Most solvents and coatings are highly flammable, particularly
when sprayed. Maintain a distance of at least 25 feet from the air compressor. If possible,
locate the air compressor in a separate room. Do not smoke while spraying.

21.	

Read all of the information concerning coating products and cleaning solvents.
Chlorinated solvents (e.g. 1-1-1 Trichlorethylene and Methylene Chloride, also known
as methyl chloride) can chemically react with aluminum and may explode. Many paint
sprayers contain aluminum. If you have any doubt about potential chemical reactions,
contact the solvent or coating manufacturer.

22.	

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 respirator or mask
when painting or using cleaning solvents.

23.	

Never release the sprayer lid while the cup is pressurized.

24.

Air Connection

For best service you should incorporate a regulator and inline filter, as shown in the diagram
above. Hoses, couplers, regulators, and filters are all available at Harbor Freight Tools.
Note: Compressor pumps discharge condensed water, oil, or other contaminants along with
the compressed air. Condensation causes “fish eyes” to appear in paint patterns. To avoid
this problem, install water/oil removal filters and controls (not included) as close to the Spray
Gun as possible. If run through the Gun, water and oil will cause damage.
1.	

You will need to prepare a 1/4” air connector (sold separately) to connect to the air inlet
on the Spray Gun. First, wrap the 1/4” air connector (not included) with pipe thread
seal tape before threading it into the Air Inlet (36). Connect the Red Air Hose (41) to
the Air Outlet Connector (36). Attach the other end of the Red Air Hose (41) to the Air
Inlet (80) on the Gun.

2.	

Set the air pressure on your compressor to 30-43 PSI. Do not exceed the maximum
air pressure of 43 PSI. Also, set the air pressure on the Air Regulator to 10-30 PSI, as
shown on the Gauge (38).

3.	

Check the air connection for leaks and then disconnect the tool from the air source.

A Comparison: Conventional versus HVLP Spray Guns
	

Because conventional spray guns require a much higher air cap pressure to atomize
the paint than HVLP Spray Guns, conventional guns have lower transfer efficiencies
and more overspray.

	

This translates to a significant paint/material savings for HVLP guns, in addition to
making them more environmentally friendly.

	

To qualify as HVLP, the dynamic air pressure going in the Air Cap must be a maximum
of 10 PSI. The lower the air pressure, the less bounce back and overspray.

	

Note: Due to the viscosity of latex and other water-based paints, they are not
recommended for use with this or other HVLP (High Volume Low Pressure) sprayers.

	See FIGURE 3 below.

IMPORTANT: The Spray Gun must be cleaned immediately after use.
Improper cleaning is a common reason for the Spray Gun not to work.

Preparation
Note: Proper paint material mixture helps to ensure less problems. Be sure to follow the manufacturer’s directions. Most materials will spray readily if they are thinned properly.
General tips for Preparation:
1.	

Mix and thin the paint/materials thoroughly according to the manufacturer’s
directions.

2.	

Carefully strain the paint/material through a paint strainer or piece of cheese cloth.

3.	

Remove (un-thread) the Cup (16) from the Unit. Fill the Cup (16) to approximately 3/4
full. Thread it back onto the unit. Connect the Fluid Hose (40) form the Fluid Outlet
(39) to the Fluid Inlet on the Spray Gun.

4.	

Start the air compressor.

5.	

To adjust the spray pattern, set up a piece of scrap material to practice on. While
practicing on the scrap material, check to see that the material you are spraying has
the appropriate consistency. If it appears to thin, add a very small amount of thinner
(not included). BE CAREFUL when thinning. Proceed slowly, adding very minimal
amounts. NEVER exceed the manufacturer’s thinning recommendations.

Fan Direction and Pattern Adjustment
Fan Direction
	
To change the direction of the fan from horizontal to vertical, loosen the Lock Ring and
turn the Air Cap (45) 90 degrees. After the adjustment, tighten the Lock Ring by hand.
See FIGURE 4 below.

Improper cleaning is a common reason for the Spray Gun not to work.
Pattern Adjustment
	
Warning!! Never exceed the Maximum Inlet PSI of 43 PSI.	
1.	

Adjust the Gauge (38) pressure to 10-30 PSI using the Air Regulator (24). If you need
to reduce the air pressure for specific areas, adjust the Air Adjustment Knob (73).

To set the pattern size specific to the job, use the Pattern Control Knob (57) (see FIGURE 1 on page 6). By turning it counterclockwise (all the way open), the pattern will
flatten. Turn the Pattern Control Knob (57) clockwise for a round pattern.
	See FIGURE 5 below.
2.	

FIGURE 5

	Flat/Open	

3.	

Round/Closed	

Close the Fluid Control Knob (67) and fully open the Fluid Flow Knob (11). See FIGURE
1 on page 6.

4.	

After setting up a piece of scrap material, squeeze the Trigger (78) in short bursts while
turning the Fluid Control Knob (67) counterclockwise and observe the spray patterns
until you see the pattern you want. Also, look at the pattern for consistency. Too much
air may cause the spray to come out too fine. Reduce the air pressure or allow more
material to come out by opening the Fluid Control Knob (67). If the spray appears too
thick (you see globs of paint), close down the Fluid Control Knob (67) slowly, checking
the mixture after each adjustment.

Improper cleaning is a common reason for the Spray Gun not to work.

Techniques
Note:	 Before spraying, mask all objects you do not want sprayed and lay cloths (not included)
on the floors.
1. 	

Always keep the gun at right angles to the workpiece (See FIGURE 7). Pull the Trigger
(78) 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 material being sprayed. Do not stop the
gun movement while spraying. If you stop the gun for even just a slight pause while
spraying, the paint will build up and run down the workpiece.

FIGURE 7

side, uneven coverage)

Incorrect

(Even coverage)

Correct (90o)

2.	

To ensure you don’t allow paint to build up, start moving the Spray Gun before you
Squeeze the Trigger (78). When you are finished spraying, release the Trigger (78)
before you stop moving the Spray Gun. Doing so will eliminate distinct overlaps,
producing a blended (feathered) affect. See FIGURE 8 below.

Note:	 The speed of the stroke, the adjustment of the Fluid Control Knob (67), and the distance
from the workpiece, will determine how much paint is being applied. To get the best
results, try to apply two thin coats of paint versus one thick coat.
3.	

Clean out the gun thoroughly after EVERY use, according to the instructions
found on the next page.

Maintenance
Solvent Selection
Always follow the paint manufacturer’s recommendations for cleaning,
solvent type, and disposing of used solvent.
Note: Due to the viscosity of latex and other water-based paints, they are not recommended for use with this or other HVLP (High Volume Low Pressure) sprayers.
Oil Based Paints: Use mineral spirits.
If a flammable solvent needs to be used, adhere to the following:
1.	 Follow all of the solvent manufacturer’s clean up instructions and
safety precautions at all times.
2.	 Always flush the Spray Gun a full hose length from the air compressor.
3.	 If collecting flushed solvents into a metal container, transfer into a larger
nonmetal container, and flush the metal container.
4.	 Work far away from any ignition sources in a vapor free area.
After each use:
1.	

Empty the Paint Cup (16) and clean it with the solvent.

2.	

Fill the Paint Cup (16) with solvent and spray it through the Gun into a container, while
shaking the gun. Once the Paint Cup (16) is empty, repeat the process until the solvent
comes out clean.

	

Disconnect from the air source. After disconnecting, be aware that air pressure
may still remain in the Spray Gun. Point the Gun into the spent solvent container and
squeeze the Trigger again to make sure no air remains.

3.	

Remove the Air Cap and soak it in solvent until it is clean. Use an old toothbrush and
toothpicks to remove any material. Do not use metal objects to clean the Air Cap
or you may damage the drilled passages. Inspect the fluid needle and make sure
it is not bent. If it is bent, have it replaced by a certified service technician.

Warning!! Do not immerse the Spray Gun Body in solvent!
4.	

Use the appropriate solvent (depending on the material sprayed) to wipe down the Gun
body.

5.	

Always lubricate the Spray Gun after cleaning. You may use a non-silicon oil or a light
lubricant on all threaded connections prior to storing the unit.

6.	

Disposal: After cleaning your Spray Gun, properly dispose of your cleaning solutions
according to the solution manufacturer’s direction and local hazardous waste
standards.

To take advantage of this warranty, the product or part must be returned to us with transportation charges prepaid. Proof of purchase date and an explanation of the complaint must

replace the product at our election or we may elect to refund the purchase price if we cannot readily and quickly provide you with a replacement. We will return repaired products at
our expense, but if we determine there is no defect, or that the defect resulted from causes
not within the scope of our warranty, then you must bear the cost of returning the product.
