SECTION 4: OPERATIONS
Spraying
EXPLOSION HAZARD! DO NOT
smoke or have any source of flame
or spark near spraying. Vapors will
explode if ignited.
RESPIRATORY HAZARD! Always use
a NOISH approved respirator when
using spray equipment. Failure to
protect your lungs can lead to respi-
ratory illness and nervous system
damage.
TOXIC FUMES! Always use an
approved spray booth or well ven-
tilated area when spraying. NEVER
spray in a confined space where
toxic fumes and flammable vapors
can accumulate to deadly levels.
The Model H7668 spray system is designed
to spray medium to high solid materials,
like lacquers, stains, primers, multi-com-
ponent 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 instruc-
tion 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 manu-
facturer's recommendations. DO NOT
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!
