Improper Spray Patterns
Heavy on top or bottom, right or left. Caused by paint buildup on air cap or fluid tip, partially plug-
ged air holes or fluid tip. To remedy, clean the cap or tip.
&$ Heavy in the center. Caused by too much, or too @$ thick material. To remedy, reduce flow by re- 0<is? ducing fluid pressure or thinning the paint.
Split pattern. Caused by insufficient paint, or too much air pressure. To remedy, increase fluid pressure or reduce air pressure.
IMake sure the HWARNING.V. power supplyIelectricity is turned off before connecting or drsconnectrng the
high voltage leads at guns or junction arm.
Connect high voltage cable to the high voltage adapter (44.
When all adjustments are made,

Care of Gun
Good housekeeping is important. Clean the gun and
work area daily. A buildup of conductive residue on either exterior or interior surfaces of gun may interfere
with proper operation.
Flush out the gun with an approved solvent at the end of the work day. Wipe the outside of the gun with an approved gun cleaner. Remove the air cap and clean it. If ionizing wire of needle (41) is bent after cleaning, straighten wire so that it is centered in fluid stream. For an approved solvent or gun cleaner, see your local sup- plier or Grace Branch. Also, refer to OSHA 29 CFR 1910.107(g)(5).
Cleaning
After each spraying operation, turn off the high voltage power supply, and solvent flush until all remaining paint is removed from hose and gun.
If air cap needs cleaning, remove and soak in clean compatible solvent (not over 15 minutes) and scrub with a fine bristled brush. To clean out holes in air cap, use a toothpick or other soft implement.
Never use metal instruments to clean holes in air entire gun in
