				SECTION 1: SAFETY   
					For Your Own Safety Read Instruction Manual   
					Before Operating This Equipment   
					The purpose of safety symbols is to attract your attention to possible hazard-   
					ous conditions. This manual uses a series of symbols and signal words which   
					are intended to convey the level of importance of the safety messages. The   
					progression of symbols is described below. Remember that safety messages by   
					themselves do not eliminate danger and are not a substitute for proper accident   
					prevention measures.   
					Indicates an imminently hazardous situation which, if   
					not avoided, WILL result in death or serious injury.   
					Indicates a potentially hazardous situation which, if   
					not avoided, COULD result in death or serious injury.   
					Indicates a potentially hazardous situation which, if   
					not avoided, MAY result in minor or moderate injury.   
					It may also be used to alert against unsafe practices.   
					This symbol is used to alert the user to useful infor-   
					NOTICE   
					mation about proper operation of the equipment.

					from work area.   
					1. KEEP ALL SAFETY DEVICES IN   
					PLACE and in working order.   
					2. REMOVE ADJUSTING KEYS AND   
					WRENCHES. Form habit of check-   
					ing to see that keys and adjusting   
					wrenches are removed from tool   
					before operation.   
					6. MAKE   
					WORKSHOP   
					CHILD   
					PROOF by locking your shop and   
					shutting off air valves.   
					7. DO NOT FORCE TOOL. It will do   
					the job better and safer at the rate   
					for which it was designed.   
					3. KEEP WORK AREA CLEAN.   
					Cluttered areas and benches invite   
					accidents.   
					8. USE THE RIGHT TOOL. Do not   
					force tool or attachment to do a job   
					for which it was not designed.   
					4. DO NOT USE IN DANGEROUS

					tool. Make sure your air hose is in   
					good condition and is long enough to   
					reach your work without stretching.   
					vicing and changing accessories.   
					18. DO NOT OVERREACH. Keep   
					proper footing/balance at all times.   
					11. WEAR PROPER APPAREL. Do not   
					wear loose clothing, gloves, neck-   
					ties, rings, bracelets, or other jew-   
					elry which may get caught in moving   
					parts. Non-slip footwear is recom-   
					mended. Wear a protective hair cov-   
					ering to contain long hair.   
					19. USE   
					THE   
					RECOMMENDED   
					ACCESSORIES. Consult owner’s   
					manual for recommended acces-   
					sories. The use of improper acces-   
					sories may cause risk of injury.   
					20. CHECK FOR DAMAGED PARTS   
					BEFORE USING. Check for bind-   
					ing and alignment of parts, broken   
					parts, part mounting, loose bolts,   
					and any other conditions that may   
					affect machine operation. Repair or   
					replace damaged parts.   
					12. ALWAYS USE SAFETY GLASSES.   
					Also use a face or dust mask if cut-   
					ting operation is dusty. Everyday   
					eyeglasses only have impact resis-   
					tant lenses, they are NOT safety   
					glasses.   
					21. NEVER LEAVE UNATTENDED   
					TOOL CONNECTED TO AIR.   
					Disconnect the air hose and do not   
					leave tool until it is relieved of any   
					built up pressure.   
					13. WEAR APPROVED HEARING   
					PROTECTION. Air escaping from   
					pneumatic tools can exceed safe   
					exposure limits and may cause   
					hearing damage with prolonged   
					exposure.   
					22. NEVER ALLOW UNTRAINED   
					USERS TO USE THIS TOOL   
					WHILE UNSUPERVISED.   
					14. SECURE WORK. Use clamps or a   
					vise to hold work when practical. It is   
					safer than using your hand and frees   
					both hands to operate tool.   
					23. IF YOU ARE UNSURE OF THE   
					INTENDED OPERATION, STOP   
					USING TOOL. Seek formal training   
					or research books or magazines   
					that specialize in pneumatic tools.

					The Model H7666/H7667 features LVLP   
					technology, which has greater transfer   
					efficiency than suction feed spray guns   
					and reduced overspray, saving on mate-   
					rial costs. LVLP spray guns also require a   
					smaller compressor because their demand   
					for air is less than HVLP systems.   
					Most importantly, we stand behind our   
					tools. If you have any service questions or   
					parts requests, please call or write us at

				SECTION 4: OPERATIONS   
					Spraying   
					The Model H7666/H7667 LVLP spray gun   
					is designed to spray medium to high solid   
					materials like lacquers, stains, primers,   
					multi-component paints, clear coats, acryl-   
					ics, epoxies etc. It is ideal for auto body   
					and woodworking projects and can be   
					used with waterborne materials.   
					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.   
					RESPIRATORY HAZARD! Always use   
					an NIOSH approved respirator when   
					using spray equipment. Failure to   
					protect your lungs can lead to respi-   
					ratory illness and nervous system   
					3. Set the inlet air pressure (the air com-   
					ing to the spray gun) to the lowest   
					pressure recommended in Tool Data   
					on Page 8 or to the material manufac-   
					turer's recommendations.   
					damage.   
					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.   
					TOXIC FUMES! Always use an   
					approved spray booth or well ven-   
					tilated area when spraying. NEVER   
					spray in an confined space where   
					toxic fumes and flammable vapors   
					can accumulate to deadly levels.

				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 con-   
					trol (on the Model H7667), and stroke   
					speed to achieve the results you want.   
					Spray so the material wets out nicely   
					without running or sagging.   
					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 6-8" 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, pos-   
					sibly 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

					Figure 5. Spray technique.   
					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.   
					HEALTH   
					& 
					CONTAMINATION   
					HAZARD! Dispose of paint waste   
					in a responsible manner! Follow   
					manufacturer's recommendations   
					and local laws regarding disposal.   
					Failure to comply will result in con-   
					tamination and possibly large fines   
					and penalties.

				Pattern Control   
					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   
					5. Unscrew the atomizing cap with your   
					Cleaning   
					fingers and the fluid tip with the ser-   
					vice wrench. The fully disassembled   
					gun should look like Figure 14.   
					Proper cleaning is the best way to ensure   
					trouble free performance from your spray   
					6. Rinse these parts thoroughly in sol-   
					gun. If your gun is not thoroughly cleaned,   
					vent then dry with compressed air or   
					damage and poor spraying will result.   
					let air dry.   
					Problems caused by improper cleaning will   
					not be covered by the warranty. Clean the   
					Note: If the small holes in the atomiz-   
					spray gun immediately after each use.   
					ing cap become blocked, soak in clean   
					solvent. If the blockage still exists,   
					clear the blockage with a small needle,   
					To clean your spray gun:   
					taking great care to not enlarge or   
					damage the hole. Damage to the hole   
					will create a disrupted spray pattern.   
					1. Spray   
					a 
					small amount of solvent   
					through the spray gun.   
					Note: Check with local laws regarding
