SECTION 4: OPERATIONS
EXPLOSION HAZARD! DO NOT smoke or have any source of flame or spark near spraying. Vapors will explode if ignited.
RESPIRATORY HAZARD! Always use a NIOSH approved respirator when using spray equipment. Failure to protect your lungs can lead to respi- ratory illness and nervous system damage.
TOXIC FUMES! Always use an approved spray booth or well ven- tilated area when spraying. NEVER spray in a confined space where toxic fumes and flammable vapors can accumulate to deadly levels.
Spraying
The Model H3256/H3257 gravity feed spray gun set is designed to spray a wide variety of materials such as lacquers, stains, primers,
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.
3.Set the inlet air pressure (the air com- ing to the spray gun) to the lowest pressure recommended in Tool Data Sheet on Page 8 or to the material manufacturer's recommendations.
4.Adjust the atomizing cap to vertical or horizontal. See Atomizing Cap and Fan Adjustments on Page 13 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.
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.
8.Use the pattern control knob to adjust the spray fan to your desired pattern.
9.Keep the gun tip perpendicular, parallel and

NOTICE
Tipping 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 gravity feed problems.
CONTAMINATION HAZARD! Dispose of paint waste in a responsible man- ner! Follow manufacturer's recom- mendations and local laws regarding disposal.
Atomizing Cap and
Fan Adjustments
The atomizing cap needs to 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 15).

SECTION 6: 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.Spray a small amount of solvent through the spray gun.
Note: Check with local laws regarding this practice. 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 the gun from the com- pressed air!
3.Unscrew the cup.
4.Unscrew the fluid control knob and remove the spring and needle.
Figure 14. Disassembly for cleaning.
5.Unscrew the atomizing cap with your fingers and the fluid tip with the ser- vice wrench. The fully disassembled gun should look like Figure 14.
6.Rinse these parts thoroughly in sol- vent, then dry with compressed air or allow them to air dry.
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 rest of the gun body with a shop towel and dry.
EXPLOSION HAZARD! Chlorinated Solvents like
