GENERAL INFORMATION
SPRAY GUN
This versatile Craftsman Spray Gun is
shipped ready for use with any tank
type air compressors delivering at
least 4.5 SCFM at 40 PSI. It is a non-
bleeder gun, which is compatible with
Sears and most other modern com-
pressors. Non-bleeder guns require air
from an air compressor having an air
regulator and an automatic start/stop
pressure switch or an automatic
pressure unloader. The gun has a
built-in air valve which shuts off the
air flow through the gun when the
trigger is released.
As a standard feature on this gun, you
have a siphon and pressure feed
setting. It is set at the factory for
siphon feed application, which makes
it ideal for applying light and medium
bodied paints (stain, lacquer) to large
size jobs such as complete auto
refinishing. The cup provided with this
gun is designed for suction feed only.
However, this gun can also be used
with a remote pressure feed paint
tank (see page 5) for spraying on
larger painting applications. When
applying heavy bodied paints, the
SG3-0030 Air Cap (included with Gun)
is recommended.
AIR CAPS
External Mix - The air and material are
mixed outside the air cap. This type of
cap is best suited for quick drying
paints, such as latex, lacquers, etc.
Internal Mix - The air and material are
mixed inside the air cap. This type of
cap is normally used for thick paint
where fast application is desired and
where quality of finish is less
important. Internal mix must be used
with pressure feed set-up.
To change air caps, turn the retaining
ring (1) counterclockwise and remove
from gun.
NOTE: This gun is designed for use
with most finishing materials. It is
not designed for use with corrosive
or highly abrasive materials. Using
these materials can lead to poor
performance and/or failure of this
product.
Remove air cap (2) and replace with
different cap. Reassemble in reverse
order.
NOTE : Matched air cap and fluid tip
combinations are recommended for
optimum performance. The fluid tip
is removed with a 1/2" socket.
When assembling, be sure the plas-
tic baffle is in place and the tip is
not cross threaded or over
tightened (160-220 in.-lbs. Torque).
PREPARATION FOR SPRAYING
Your Craftsman spray gun is shipped
completely assembled, and
set-up
for siphon feed spraying. Installa-
tion is accomplished by connecting
an air line to the air inlet adapter (44)
shown on page 9.
This spray gun should be flushed with
solvent prior to spraying with paint.
The fluid needle packing (13) in this
gun may be loose when received.
Tighten the packing retainer (14) until
it grabs and holds the fluid needle (9),
then back off the packing retainer
(approx. 1/4 turn) until the fluid needle
is free to travel into the fluid tip (3).
Be sure the surface to be sprayed is
dry and free of all dirt, grease, oil and
loose paint. Mix and prepare the paint
according to the manufacturer's
instructions. The use of a Sears
viscosimeter can be very helpful.
Strain the material to be sprayed
through a 60 to 90 mesh screen or
equivalent.
To use a quick disconnect, remove
the air hose adapter (44) and install a
1/4" NPT quick disconnect adapter
into the handle of the gun body (19).
Set air pressure at 40 psi as a starting
point and follow the safety precau-
tions on page 3 before you begin.
