OPERATIONS
EXPLOSION HAZARD! DO NOT smoke or have any source of flame or spark near spraying. Vapors will explode if ignited.
Spraying
The Model H8222 siphon feed spray gun set is designed to spray a wide variety of materials such as lacquers, stains, prim­ers, multi-component paints, clear coats, acrylics, epoxies etc. It is ideal for auto body and woodworking projects.
To use your spray gun :
1. Read and follow the material manufac-
turer's instructions for spraying, mixing, safety, disposal, and any other instruc­tion 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.
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.
3. Set the inlet air pressure (the air coming
to the spray gun) to the lowest pres­sure recommended in Specifications on Page 3 or to the material manufac­turer's recommendations.
4. Adjust the atomizing cap to vertical or horizontal. See Atomizing Cap and Fan Adjustments on Page 8 for fur­ther 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.

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 sag­ging.
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.
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 spray­ing.
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.
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.
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! Dispose of paint waste in a responsible manner! Follow manuf acturer's recommendations and local laws regarding disposal.
Atomizing Cap and
Fan Adjustments
atomizing cap can be adjusted for
The 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).

ACCESSORIES
G62 61— Campbell Hausfeld™ Water Filter
Filtering out water and oil before it reaches the spray gun is critical for high quality spraying results. This filter is rated at 150 PSI maximum air pressure, and has a 1⁄4" NPT air inlet.
Figure 10. G6261 Campbell Hausfeld™
water filter.
G8114—3⁄8 " x 25 Ft. Air Hose G8115—3⁄8 " x 50 Ft. Air Hose G8116—3⁄8 " x 100 Ft. Air Hose
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 1⁄4" NPT ends.
H7274— Campbell Hausfeld™ Pressure Regulator
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. 1⁄4" NPT.

pressure regulator.
H3275 —1⁄4" NPT x 25' Recoil Hose H3276 —1⁄4" 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.

MAINTENANCE
Cleaning
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.
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.
2. DISCONNECT SPRAY GUN FROM AIR!
3. Remove the cup and cup lid.
5. Unscrew the atomizing cap and the
fluid tip. The fully disassembled gun should look like Figure 14.
6. Rinse all par ts 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.
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.
8. Wipe the gun body with a lint free shop towel to dry.
4. Disassemble the gun by unscrewing the fluid control knob then remove the spring and needle.
