SAFETY GUIDELINES
This manual contains information that is important for you to know and understand.
This information relates to YOUR SAFETY and PREVENTING EQUIPMENT PROBLEMS.
To help you recognize this information, we use the following symbols. Please read the manual
and pay attention to those sections.
IMPORTANT SAFETY INFORMATION - A HAZARD THAT
MIGHT CAUSE SERIOUS INJURY OR LOSS OF LIFE.
NOTE
Information that you should pay special attention to.
Information for preventing damage to equipment.

HAZARDS CAN OCCUR DURING NORMAL USE OF THIS EQUIPMENT.
PLEASE READ THE FOLLOWING CHART.
WHAT TO
LOOKFOR
When paints or materials are sprayed, they are broken
into very small particles and mixed with air. This will
cause certain paints and materials to become ex-
tremelyflammable.
Flammable
Spray
Materials
Toxic Vapors Somepaints and coatingsmaybeharmfulifinhaled or
allowed to come into contact with skin or eyes.
Sprayed materials such as paint, paint solvents, paint
remover, etc., contain harmful vapors and poisons.
Pressurized
Parts
Certain parts are under pressure whenever the gun is
connectedtoapressurizedairline.Thesepartsmaybe
propelled if the gun is disassembled.
Disconnect the gun from the air line, or completely
depressurize the air line whenever the gun is to be
disassembled.
HOW TO PREVENT IT
WHAT COULD HAPPEN
Work in an area with good cross ventilation. Read
and follow the safety instructions provided on the
label or safety instructions. Provided on the material
label or safety data sheets for the material you are
spraying. Use a NIOSH/MSHA approved respirator
designed for use with your specific application.
Never spray near open flames or pilot lights in stoves
or heaters.
Never smoke while spraying.
Provide ample ventilation when spraying indoors.
Compressed
Air
Compressed air may propel dirt, metal shavings, etc.
and possibly cause an injury.
Never point any nozzle or sprayer toward a person or
part of the body.
Always wear ansi 287.1 approved safety glasses with
side shields when using compressed air.
AIR REQUIREMENTS
3.4
Minimum SCFM required @ 40 P.S.I.
Explosion
Hazard -
Incompatible
Materials
The solvents 1,1,1-Trichloroethane and Methylene
Chloride can chemically react with the aluminum
used in most spray equipment, including this gun and
cup, to produce an explosion hazard.
Read the label or data sheet for the material you intend
to spray.
1. Do not use any type of spray coating material
containing these solvents.
2. Do not use these solvents for equipment cleaning
or flushing.
3. If in doubt as to whether a material is compatible,
contact your material supplier.

GENERAL INFORMATION
INSTALLATION
(Figure 1) Attach nut of paint cup
assemblyto1/4"NPTfluidinletnipple
onspraygun. Tightenonlyuntil snug.
Position yoke at right angle to gun
body with cam toward front of gun.
Connect atomization air line to air
compressor.
OPERATION
This Craftsman Detail Touch-up gun should be flushed
with solvent prior to spraying with paint.
A. Adjust air pressure to approximately 30 P.S.I. The
use of an air regulator assures clean, dry air.
B. Turn needle adjustment screw out until first
thread shows. This places the tip and needle in a full
open position which gives maximum tip and needle
life. Never turn all the way in, as trigger cam will
break.
C. Turnfan adjusting screwout until first thread shows.
D. Press trigger and adjust needle adjusting screw for
desired material flow.
E. Press trigger and observe atomization of fluid. If it is
too great, decrease air pressure at regulator. If it is
not enough, increase air pressure at regulator.
F. Press trigger and adjust fan adjusting screw until
desired pattern is obtained. A perfect pattern is a
full, even coat from end to end. Each time needle
adjusting screw is adjusted Step E should be re-
peated.
PREPARING PAINT
Be sure the surface to be sprayed is dry
and free of all dirt, grease, oil and loose
paint. Mix and prepare paint in accor-
dance with the manufacturer's instruc-
tions. Strain material to be sprayed
througha60to90meshscreenorequiva-
lent.
CONTROLLING THE FAN SPRAY
(Figure2)Thefan spray foranexternal
mix nozzle set up is easily controlled
by means of the fan adjusting screw.
Byturningtothe right (clockwise)until
it is closed will give a rounded spray;
turning it to the left (counterclock-
wise) will widen the spray into a fan
shape of any width desired. The di-
rection of the fan spray (horizontal or
vertical) is obtained by turning the air
nozzle to the desired position, then
tightening the air cap/retaining ring.
Tighten only finger tight. Do not use
pliers or wrench to tighten or loosen.
FIGURE 1
DESCRIPTION
The Craftsman Detail Touch-Up Gun is the only spray gun of its type that can be simply converted for use by a left
or right handed sprayer, by simply unscrewing the trigger screw, turning the trigger over and re-inserting the trigger
screw. The complete Craftsman Detail Touch-Up Gun consists of a detail touch-up gun and 8 oz. (240 cc) suction cup
assembled. The detail touch-up gun is a non-bleeder, suction feed, external mix type. The cup has a one half pint
capacity.
FIGURE 2
NOTE: This spray gun is designed to spray stains, acrylics, lacquers, primers, automotive metallics and
other light and medium viscosity finishes. Most unreduced latex or other heavy bodied materials require
the use of a pressure feed paint tank. If used with corrosive, rust-inducing, or highly abrasive materials,
frequent and thorough cleaning will be required and/or may increase the need for replacement parts.

6
To Clean Gun: Spray a small amount of clean solvent
throughthegun. Neverimmersethe gun insolvents as this
removes lubricants and dries out the packings. A caustic
solution should not be used to clean gun, as this will
destroy the aluminum alloy. Remove air nozzle and wash
it in solvent. If necessary to clean air nozzle holes, use a
broom straw or toothpick. Never use a steel wire or hard
instrument as this will result in distortion of spray pattern.
Wipe exterior of gun with solvent soaked cloth. Never
soak gun in liquid detergent.
To Lubricate gun: After each day's use place a drop of
oil at trigger screw, fan control packing, and fluid needle
packing. Occasionally remove fan control spring and
recoat with a light grease or Vaseline.
MAINTENANCE
Properadjustment ofyour CraftsmanDetail
Touch-Up Gun will give you a normal spray
patternof this shape (see illustration).If not,
consult service check list on next page.
NOTE: If water is used as a solvent, clean
the gun, and spray paint thinner or mineral
spirits through the gun after cleaning to
remove any excess moisture and protect
parts.
CONTROLLING THE FLUID
If a fluid pressure tank is used, the amount of fluid can be
controlled by regulating the pressure on the tank. The
amount of fluid can also be controlled by means of the
fluid needle adjusting screw. By turning it clockwise (to
the right), the amount of fluid is reduced. Turning it
counterclockwise (to the left) increases the amount of
fluid.
HINTS FOR GOOD SPRAYING TECHNIQUES
At all times hold the spray gun perpendicular to the
surface being sprayed. A spraying distance of 6-8 inches
isrecommended. This distance can be varied depending
onthe item being sprayed, the material orthe airpressure
used. Release the trigger at the end of each lateral stroke
while the gun is still traveling. Start the gun moving at the
beginning of the next stroke so the gun is in motion when
the trigger is pressed (see illustration). This action should
be practiced until a smooth, steady, rhythmic stroke
becomesnatural.
Overlap each stroke 50%. This is done by aiming the gun
at the edge of the last stroke. A short practice period will
benecessary to achievean evenstroke.Avoid archingthe
gun as this will leave an uneven coat of paint (see
illustration).
Preventive maintenance should head off some problems
commonlyencountered. Remember yourdetail touch-up
gunis precisionengineered and proper maintenance can
help you get the fine quality results you desire.

TROUBLESHOOTING GUIDE
PROBLEM CAUSE CORRECTION
Determinewhere materialbuild-up isby inverting
cap and test spraying. If pattern shape stays in
same position, the condition is caused by mate-
rial build-up on fluid tip. If pattern changes with
cap movement, the condition is in the air cap.
Soakcap ortip insuitable solvent and wipe clean.
To clean orifices use a broom straw or toothpick.
Never use a wire or hard instrument. This dam-
ages holes and distorts its spray pattern.
Heavy top or bottom
pattern.
Heavy right or left side
pattern.
Material build-up on air cap or fluid
tip. Partially plugged horn holes,
center holes or fluid tip hole.
