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.

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.

SECTION 4: OPERATIONS  
Spraying  
The Model H7671/H7672 HVLP spray gun  
set is designed to spray a wide variety of  
materials like lacquers, stains, primers,  
multi-component paints, clear coats, acryl-  
ics, 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.  
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.  
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.  
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.  
Model H7671/H7672 HVLP 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 6-8" 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  
Page 17.  
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.  
CONTAMINATION HAZARD! Dispose  
of paint waste in a responsible man-  
ner! Follow manufacturer's recom-  
mendations and local laws regarding  
disposal.

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).
