How to Set Up
Your Craftsman spray gun is shipped
completely assembled, and set-up for
siphon feed spraying.
Prior to shipment, this gun was treated
with an anticorrosive agent. Before
using this gun flush it with a suitable
solvent (mineral sprits is a suitable
solvent).
To Flush Spray Gun Before Use
1. Remove the material cup from
lid/gun assembly. NOTE: Slide
release lever to the right, rotate
lid, and remove material cup.
2. Fill the material cup 3/4 full with a
suitable solvent.

Before Using Spray Gun
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.
1. Mix material according the
manufacturer’s instructions.
Mixture should be smooth and
easily pourable. Lumps or foreign
particles should be removed by
straining through a suitable paint
filter. NOTE: Using a Sears
Viscosimeter will help in
measuring the viscosity or
thickness of the material.
Bend
IMPORTANT: The use of a oil/water extractor is recommended. See set
illustrations for examples.

other person. Accidental discharge
of material may result in serious
injury.
To adjust spray pattern and fluid
pressure:
• To adjust the fluid, turn fluid con-
trol knob counterclockwise to in-
crease or clockwise.
• To adjust the air flow, turn pattern
control knob counterclockwise to
increase or clockwise to de-
crease.
• To fine tune the air flow, turn air
valve control knob counterclock-
wise to increase, or clockwise to
decrease.
IMPORTANT: Always clean gun after
each use. See "Maintenance" section
for correct procedure.
Before Using Your Spray
Gun
1. Set up spray gun as described
in the "How to Set Up Spray
Gun" paragraph in the
"Assembly" section of this
manual.
To Use Spray Gun
1. The position of the air cap horns
will determine the fan spray
pattern. Loosen air cap and rotate
horns to achieve desired pattern.
Tighten air cap.
2. Turn fluid control knob clockwise
until it stops, do not force. This
will shut off the fluid flow. NOTE:
The fluid or density of “fan spray”
is controlled by fluid control
knob.
3. Turn pattern control knob
counterclockwise until first thread
is flush with gun body. NOTE: Air
flow is controlled by pattern con-
trol knob.
DO NOT turn pattern
control knob or fluid
control knob counter clockwise after
first thread is flush with the gun
body. They are under pressure when
the gun is triggered and could leave
the gun with force.

• Don't arc strokes, move the gun
parallel to work.
• Pattern should be
shaped as shown, if not
see "Troubleshooting"
section.
• Care should be exer-
cised when handling spray gun to
avoid damage to the orifice of the
air cap and tip of fluid nozzle.
Damage to these parts results in
irregular spray patterns.
• Practice on a cardboard target to
make sure pattern size and
material consistency are correct
before spraying on actual project.
Operating Tips
• To reduce overspray and obtain
maximum efficiency, always spray
with the lowest possible fluid/air
pressure.
• Hold the gun perpendicular to the
surface, 4" to 6" distance.
• Two thin coats will produce a
better finish than one heavy coat.
• Mask off areas not being
sprayed.
• Follow contour.
• Overlap each stroke 50%.
• Ends are feathered by triggering.
That is, begin stroke before
pulling trigger and releasing just
before ending the stroke.
• Spray edges and corners first.
This will reduce overspray while
providing good coverage on
corners.
