OPERATIONS  
Spraying  
The Model H8222 siphon feed spray gun  
set is designed to spray a wide variety of  
materials such as lacquers, stains, prim-  
ers, multi-component paints, clear coats,  
acrylics, epoxies etc. It is ideal for auto  
body and woodworking projects.  
EXPLOSION HAZARD!  
DO NOT smoke or have any source  
of flame or spark near spraying.  
Vapors will explode if ignited.  
To use your spray gun:  
1. Read and follow the material manufac-  
turer's instructions for spraying, mixing,  
safety, disposal, and any other instruc-  
tion on the label or Material Safety Data  
Sheet (MSDS).  
2. Ensure the cup is securely tightened  
and all other fittings are secure to avoid  
air leaks or material spills.  
EYE AND RESPIRATORY HAZARD!  
Always wear ANSI approved goggles  
and a NIOSH approved respirator  
when using spray equipment. Failure  
to protect yourself can lead to severe  
eye/lung injuries.  
3. Set the inlet air pressure (the air coming  
to the spray gun) to the lowest pres-  
sure recommended in Specifications  
on Page 3 or to the material manufac-  
turer's recommendations.  
4. Adjust the atomizing cap to vertical or  
horizontal. See Atomizing Cap and  
Fan Adjustments on Page 8 for fur-  
ther explanation.  
5. Fill the cup with material.  
6. Trial-and-error are necessary to  
achieve the results you want along with  
a fair amount of practice. Test your  
material flow and spray pattern on a  
piece of cardboard or some scrap of  
material similar to your project.  
TOXIC FUMES!  
Only spray in well ventilated areas  
or an approved spray booth. NEVER  
spray in a confined space where  
toxic fumes and flammable vapors  
can accumulate to deadly levels.  
-6-  
Model H8222 Spray Gun  
 
7. Adjust the fluid control knob to start  
with a low volume of material and keep  
the atomization as low as possible.  
You will need to use a combination of  
fluid control, inlet air pressure, air flow  
control and stroke speed to achieve the  
results you want. Spray so the material  
wets out nicely without running or sag-  
ging.  
10. Begin spraying 2-3 inches before the  
work and continue to the end of the  
work. Continue the motion for a few  
inches past the work until you are  
ready for the return stroke.  
11. Maintain an even speed when spray-  
ing.  
12. Overlap each stroke by 50%. This will  
ensure even coverage as shown in  
Figure 6. Overlapping less than 50%,  
as shown in the figure to the right,  
may lead to missed spots or streaky  
results.  
8. Use the pattern control knob to adjust  
the spray fan to your desired pattern.  
9. Keep the gun tip perpendicular, parallel  
and 6"-12" from the work at all times  
when spraying, as shown in Figure  
5. Do not allow your wrist to bend.  
This will cause the gun to arc across  
the surface and distribute the material  
unevenly, possibly creating sags and  
dry spots.  
No  
Yes

Figure 6. Overlap technique.  
13. The spray stroke should have even con-  
sistency and parallel edges. If it doesn't,  
please refer to Troubleshooting on  
Page 12.  
Figure 5. Spray technique.  
NOTICE  
Tipping the spray gun may cause  
material to spill out of the cup. Always  
hold the spray gun perpendicular to  
the ground to avoid potential spills  
and feed problems.  
CONTAMINATION HAZARD!

manner! Follow manufacturer's  
recommendations and local laws  
regarding disposal.

Atomizing Cap and  
Fan Adjustments  
Pattern  
The atomizing cap can be adjusted for  
horizontal or vertical spraying patterns.  
Spraying in the wrong direction may lead  
to material build up on the atomizing cap  
horn. Many performance problems are  
caused by clogged atomizing holes on the  
atomizing cap horns (see Cleaning on  
Page 10).  
Stroke  
Figure 8. Set up for horizontal spray stroke  
with vertical fan pattern.  
Rotating the pattern adjustment knob (see  
Figure 3) changes the shape of the spray  
pattern from a wide spray to a narrow  
spray, as shown in Figure 9.

ACCESSORIES  
H7274—Campbell Hausfeld™ Pressure  
G6261—Campbell Hausfeld™ Water  
Regulator  
Filter  
Since PSI drops through lengths of air  
hose, attaching a regulator directly to the  
spray gun ensures accurate air regulation  
for the best results possible. Provides  
regulated output pressure of 0 to 125 PSI  
for proper tool operation. Locking pressure  
knob prevents accidental adjustments. 15  
SCFM flow capacity @ 90 PSI. 14" NPT.  
Filtering out water and oil before it reaches  
the spray gun is critical for high quality  
spraying results. This filter is rated at 150  
1
PSI maximum air pressure, and has a 4  
NPT air inlet.

H3275—14" NPT x 25' Recoil Hose  
H3276—14" NPT x 50' Recoil Hose  
These recoil hoses are great dedicated air  
hoses because they are extremely light  
weight and maneuverable, which makes  
hours of spraying less tiring on wrists and  
arms.  
We recommend dedicating an air hose for  
spraying use only, keeping it clean and  
free of water and oil by using a filter on the  
incoming end. Multi-purpose red rubber  
air hose is flexible and abrasion resistant.  
Features 200 PSI rating, 800 PSI bursting  
strength, and 14" NPT ends.

MAINTENANCE  
5. Unscrew the atomizing cap and the  
Cleaning  
fluid tip. The fully disassembled gun  
should look like Figure 14.  
Proper cleaning is the best way to ensure  
trouble free performance from your spray  
gun. If your gun is not thoroughly cleaned,  
damage and poor spraying will result.  
Problems caused by improper cleaning will  
not be covered by the warranty. Clean the  
spray gun immediately after each use.  
6. Rinse all parts thoroughly in solvent,  
then dry with compressed air or let  
air dry. Try not to expose O-rings to  
solvent or they may get damaged.  
Note: If the small holes in the atomiz-  
ing cap become blocked, soak in clean  
solvent. If the blockage still exists,  
clear the blockage with a small needle,  
taking great care to not enlarge or  
damage the hole. Damage to the hole  
will create a disrupted spray pattern.  
To clean your spray gun:  
1. Empty the cup and spray a small  
amount of solvent through the gun.  
Note: If you are spraying on a regular  
basis, spraying solvents into the air  
may be illegal. A cabinet style spray  
gun cleaner may be required.  
7. Use the cleaning brush with solvent to  
clean the inner orifice and other hard  
to reach areas on the outside of the  
spray gun body.  
2. DISCONNECT SPRAY GUN FROM
