SECTION 4: OPERATIONS
EXPLOSION HAZARD! DO NOT
smoke or have any source of flame
or spark near spraying. Vapors will
explode if ignited.
RESPIRATORY HA ZARD! Always use
a NOISH approved respirator when
using spray equipment. Failure to
protect your lungs can lead to respiratory illness and nervous system
damage.
Spraying
The Model H7668 spray system is designed
to spray medium to high solid materials,
like lacquers, stains, primers, multi-component paints, acrylics, epoxies etc. It is
ideal for auto body, farm and commercial
maintenance projects. It is not for use with
any waterborne material.
To use your spray system:
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. After mixing, filter the material through
a strainer while filling the pressure cup.
(Strainers are available from your paint
supplier.)
3. Fill the pressure cup 3⁄4 full or less. DO
NOT OVERFILL. Overfilling will cause
pressurization problems and contribute
to leaks and spills.
4. Tighten the cap securely on the pres-
sure cup and ensure all other fittings
are secure to avoid air leaks or material
spills.
5. Set the inlet air pressure (the air com-
ing to the pressure cup) between 29
and 43.5 PSI or to the material manufacturer's recommendations. DO NOT
TOXIC FUMES ! Always use an
approved spray booth or well ventilated area when spraying. NEVER
spray in a confined space where
toxic fumes and flammable vapors
can accumulate to deadly levels.
Model H7668 Spray Gun w/Pressure Cup -11-
exceed 50 PSI for any reason.
Note: Periodically pull the ring on the
safety valve to ensure it moves freely.
Do not use the pressure cup if the
safety valve is not working!
Page 12
6. Set the pressure control knob to regu-
late the fluid pressure to the gun.
Please follow material manufacturer's
recommendations for this setting.
7. Adjust the atomizing cap to vertical or
horizontal. See Atomizing Cap and
Fan Adjustments on Page 13 for further explanation.
8. 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.
9. 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.
10. Use the pattern control knob to adjust
the spray fan to your desired pattern.
11. Keep the gun tip perpendicular, parallel
and 8-10" from the work at all times
when spraying as shown in Figure
10. 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.
Figure 10. Spray technique.
12. 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.
13. Maintain an even speed when spraying.
14. Overlap each stroke by 50%. This will
ensure even coverage as shown in
Figure 11. Less than 50% as shown
in the figure to the right may lead to
missed spots or streaky results.
Yes
Figure 11. Overlap technique.
15. Spray stroke should have even consis-
tency and parallel edges. If it doesn't

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
HE ALTH & CO NTAMIN ATIO N
Proper cleaning is the best way to ensure
trouble free performance from your spray
system. If your system 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, hose and pressure
cup immediately after each use.
To clean your spray system:
1. Depressurize the cup by disconnecting
from the compressed air and bleed
the system by loosening (DO NOT
REMOVE) the pressure relief valve
until "zero" pressure is recorded on the
pressure cup gauge (see Figure 20).
EXPLOSION HA ZARD ! Do not
unscrew pressure cup lid while
under pressure! Exploding paint
material and solvents could cause
serious injury!
HAZARD! Dispose of paint waste
in a responsible manner! Follow
manufacturer 's recommendations
and local laws regarding disposal.
Failure to comply will result in contamination and possibly large fines
and penalties.
2. Unscrew the cap and empty the pres-
sure cup contents into an approved
receptacle.
EXPLOSION HAZARD! Chlorinated
Solvents like 1,1,1-Tricloroethane
and Methylene Chloride (methyl
chloride) can chemically react with
aluminum and may explode. Many
parts in spray guns and pressure
cups are made of aluminum. Read
your solvent label carefully before
using solvent.
3. Clean pressure cup with solvent.
4. Add clean solvent to pressure cup,
replace the lid and repressurize.
5. Spray the gun until the fluid sprays
clear to clean the fluid hose.
Note: Check local laws regarding this
