OPERATIONS
Tank Regulator
The pressure regulator on the paint tank
controls the amount of pressure in the
paint tank and the spray gun.
The following are operating guidelines for
internal and external spray guns:
Internal Mix Guns: Use higher tank
pressures up to the full amount of air
pressure being delivered to the spray gun.
However, do not exceed 50 PSI at the
spray gun or in the paint tank.
External Mix Guns: Use lower tank
pressures—approximately 12 PSI for most
external mix guns. Start with the tank at
"zero" pressure and increase pressure
gradually until the correct spray pattern is
achieved.
Do not exceed the 50 PSI maximum
operating pressure on your paint tank.
Exceeding the maximum pressure
may cause the tank to explode,
causing serious personal injury.
RESPIRATORY HAZARD! Always use
a NIOSH approved respirator when
using spray equipment. Failure to
protect your lungs can lead to respiratory illness and nervous system
damage. Spraying some paints and
varnishes may require a supplied air
respirator system.
TOXIC FUMES! Always use an
approved spray booth or well ventilated area when spraying. NEVER
spray in an confined space where
toxic fumes and flammable vapors
can accumulate to deadly levels.
EXPLOSION HAZARD! DO NOT
smoke or have any source of flame
or spark near spraying. Vapors will
explode if ignited.

Read the manual before operation.
Become familiar with this tool, its
safety instructions, and its operation
before beginning any work. Serious
personal injury may result if safety
or operational information is not
understood or followed.
2. Pour paint into the tank; or set a one
gallon can of paint in the tank, making
sure the lid's fluid tube is seated in the
can.
3. Place the lid assembly on the tank and
evenly hand tighten the lid clamp wing
screws.
4. Adjust the regulator at your air compressor to 50 PSI.
Like all tools there is potential danger
when operating this tool. Accidents
are frequently caused by lack of
familiarity or failure to pay attention.
If normal safety precautions are
overlooked or ignored, serious
personal injury may occur.
NOTICE
This paint tank is not designed for
use with highly abrasive, corrosive,
or rust inducing materials. If such
materials are used, frequently and
thoroughly clean all components to
reduce the need to replace parts.
5. Fully turn the regulator T-handle counterclockwise to shut the tank regulator
OFF.
6. Connect the paint tank to the air compressor.
7. Adjust the paint tank to 25 PSI on the
tank pressure gauge. Normal operating
pressure is 25-30 PSI. Using trial and
error, adjust the paint tank as necessary between this range for optimum
results.
8. Adjust the regulator at the spray gun.
9. Start by testing the spray gun at a low
setting, then increase the air pressure
as needed for satisfactory results.

Spraying
The Model H8225 siphon feed spray gun
set is designed to spray a wide variety
of materials such as lacquers, stains,
primers, multi-component paints, clear
coats, acrylics, epoxies etc. It is ideal for
auto body and woodworking projects.
8. Use the pattern control knob to adjust
the spray fan to your desired pattern.
To use your spray gun:
1. Read and follow the material manufacturer's instructions for spraying, mixing,
safety, disposal, and any other instruction on the label or Material Safety Data
Sheet (MSDS).
2. Ensure the tank and hoses are securely tightened and all other fittings are
secure to avoid air leaks or material
spills.
3. Set the inlet air pressure (the air coming to the spray gun) to the lowest
pressure recommended or to the material manufacturer's recommendations.
4. Adjust the atomizing cap to vertical or
horizontal. See Atomizing Cap and
Fan Adjustments on Page 11 for further explanation.
5. Fill the tank with material.
6. Test your material flow and spray pattern on a piece of cardboard or scrap
material similar to your project. Trial
and error are necessary to achieve the
results you want.
-10-
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 sagging.
9. Keep the gun tip perpendicular to the
ground, parallel to the surface­ and
6-12" from the work at all times when
spraying, as shown in Figure 5. Do not
bend your wrist. This will cause the gun
to arc across the surface and distribute
the material unevenly, possibly creating sags and dry spots.
