SPRAY GUN
This versatile Craftsman Spray Gun is shipped ready for use
with any larger air compressors delivering at least 7 0 SCFM
at 40 PSI, It is a non-bleeder gun, which is compatible with
Sears and most other modern compressors,, 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 offthe air flow through the gun when the trigger
is reteased_
The cup provided with this gun is designed for suction feed
only, which makes it ideal for applying light and medium
bodied paints (stain, lacquer) to large size jobs such as
complete auto refinishing. However, this gun can also be
used with a remote pressure feed paint tank (see page 5) for
spraying on larger painting applications,
Suction Cup Removal - * The Sipon Feed Cup supplied
with this gun has a built in socket feature in the top of the
yoke. This allows the lid and tube assembly to be removed
from the gun without using a 3/4" wrench.
To use this feature, remove the paint cup and lift the yoke
over the nut The yoke will fit over the nut similiar to a 12
point socket Gripping the outer portions of the yoke and
turning allows the nut to be tightened and loosened,,
NOTE
This gun is designed for use with most
finishing materials. It is not designed for
use with corrosive or highly abrasive mate-
rials. Using these materials can lead to
poor performance and/or failure of this
product.
AIR CAPS
External Mix TThe air and material are mixed outside the
air cap, This type of cap is best suited for quick drying paints,
such as latex, lacquer's, etc,,
PREPARATION FOR SPRAYING
Your Craftsman spray gun is shipped completely assembled,
and set-up for siphon feed spraying. Installation is accom-
plished by connecting an air line to the air inlet adapter' (44)
This spray gun should be flushed with solvent prior' to
spraying with paint.
The fluid needle packing (8) in this gun may be loose wilen
'eeeived. Tighten the packing retainer (9) until it grabs and
holds the fluid needle (21 ), then back offthe packing retainer
(approx, 1/4 turn) until the fluid needle is free to travel into
the fluid nozzle (4)r
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.
Be sure the surface to be sprayed is dry and flee of all dirt,
grease, oil and toose 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 thorugh a 60 to 90 mesh screen or equivalent.
Set air pressure at 40 psi as a starting point and follow the
safety precautions in the "Safety Guidelines" before you
begin.

GENERAL INFORMATION
CONVERTING TO REMOTE PRESSURE FEED
I,. Remove suction cup and lid assembly by loosening and
removing the swivel nut (36),
OPERATION
1. Shut off fluid flow through gun by turning fluid needle
adjusting screw (25) clockwise as far as it will gooDo not
force.
2, Keep the air pressure as low as possible.
3r Open (turn counterclockwise) air valve assembly (10)
until the first thread is flush with the back of guno This is
the full open position,
4. Hold the trigger (13) back and gradually open the fluid
needle adjusting screw (25) until a desired pattern is
obtained.
5. Trigger the gun quickly, one second on-offoSpray a small
test pattern°
MAINTENANCE
2 The spray gun is now ready to be connected to any
pressure feed tank with a standard 3/8" straight pipe
female connection°
6 If the gun sprays too fast (runs or sags), lower the air and
fluid pressure.. If too slow, increase pressure. Adjust to
balance pressure.
When using internal mix air cap, begin with the same air and
fluid pressure°
The SG5-0010 air valve (10) is under pressure
whenever the gun is triggered. If the valve is
turned out too far, it mayleave the gun forcefully
when the gun is triggered. The "0" ring may also
be damaged. Do not turn the valve out past the
first thread--there will be no effect on the spray
pattern after that position.
Thoroughly clean the spray gun after each use°
1oTurn off air supply, and remove cup from lid.
2. Empty the material from cup and rinse with a clean
solvent (thinner).
3. Fill cup with solvent and attach to the lid_
NOTE
Always clean with reduced air pressure. An
air pressure no greaterthan 15 to 20 PSI will
allow quick and thorough cleaning of the
cup and gun.
4. Turn on the air supply and spray solvent through the spray
gun. While spraying, shake the gun up and down to
remove all excess material from the lid. Repeat Steps I-
4 above with a clean solvent until all traces of material are
removed.
5. Turn off air supply to gun.
6. To clean the vent hole, shut offair to gun, hold the trigger
back and turn gun assembly upside down over solvent
container. Allow solvent to drip out vent hole in lid until
clear solvent is seen..
7,
Wipe the outside of the spray gun and cup with a solvent
soaked cloth. DO NOT IMMERSE THE GUN IN SOL-
VENT - THIS WILL WASH OUT THE LUBRICANTS
AND DRY OUT PACKINGS.
.
To clean the air cap and fluid tip, remove them (see Air
Caps), soak in suitable solvent and wipe clean with a
clean cloth. If the holes are plugged, use a wooden
toothpick to remove any material particles. NEVER use
a needle or any other metal object as this may damage the
holes and result in imperfect spray patterns° When reas-
sembling the fluid tip, take care not to overtighten (160-
200 in.lbso torque is recommended) or cross thread the
fluid tip into the gun body.
NOTE
if water is used as a solvent to clean the
gun, spray paint thinner or mineral spirits
through the gun after cleaning to remove
any excess moisture and protect parts.
After cleaning the spray gun, apply a few drops of light
household oil to the fluid needle (21) next to the packing
retainer (9), on the threads of the air valve assembly (I0) and
that part of the valve stem (.20) which protrudes from the gun
body, All springs should be given a coating of light grease
periodically

GENERAL INFORMATION
HINTS FOR GOOD SPRAYING RESULTS
u,u nnn iin lulllll
. Hold the gun perpendicular to the surface, 6" to 8" distance.
• Follow contour,
• Overlap each stroke 50%_
• Ends are feathered by triggering. That is, begin stroke
before pulling trigger and releasing just before ending the
stroker
• Spray edges and comers f'trsto 7"his wilt reduce overspray
while providing good coverage on comers.
• Don't arc strokes, move the gun para!lel to work
TROUBLESHOOTING GUIDE
CAUSE CORRECTIONPROBLEM
Heavy top or bottom
Material build-up on air cap or fluid
tip. Partially plugged horn holes,
center holes or fluid tip hole,
Heavy right or left side
pattern. }
Your pattern should normally be shaped like this,
If not, see Troubleshooting Guide,
Determine where material build-up is by inverting
cap and test spraying, If pattern shape stays in
same position, the condition iscaused by mate-
rial build-up on fluid tip, If pattern changes with
cap movement, the condition is in the air cap.
Soak cap or tip in suitable solvent and wipe clean.
To clean orifices use a broom straw or toothpick.
Never use a wire or hard instrument. This dam,-
ags holes and distorts its spray pattern,,
