Materials

Toxic Vapors

Air

Pressurized

Parts

Explosion

Hazard -

Incompatible

Materials

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 be-

come extremely flammable

Some paints and coatings may be harmful if inhaled

or allowed to come into contact with skin or eyes

Compressed air may propel dirt, metal shavings, etc.

and possibly cause an injury

Certain parts are under pressure whenever the gun is

connected to a pressurized air line_ These parts may

be propelled if the gun is disassembled.

The solvents 1,1,1-Tdchloroethane and Methylene

Chlodde can chemically react with the aluminum

used in most spray equipment, and this gun and cup,

to produce an explosion hazard

or heaters.

Never smoke while spraying

Provide ample ventilation when spraying indoors.

Use a mask or resp=rator =fthere =sa chance of inhaling

toxic sprayed materials Masks and respirators have

limits and will only provide protection against some

kinds and limited amounts of toxic material Read

mask and respirator instructions carefully. Consult

with a safety expert or industdal hygienist if you are not

sure about the use of a certain mask or respirator.

Never point any nozzle or sprayer toward a person or

partof the body_

Always wear safety goggles or glasses when spraying.

Disconnect the gun from the air line, or completely

depressurize the air line whenever the gun is to be

disassembled.

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

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 pin, turning the trigger over and re-inserting the trigger pin.

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.

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 reqt,ired and/or may increase the need for replacement parts.

INSTALLATION

(Figure 1) Attach nut of paint cup

assembly to 1/4" NPT fluid inlet

nipple on spray gun, Tighten only

until snug, Position yoke at right

angle to gun body with cam toward

front of gun, Connect atomization

air line to air compressor.,

PREPARING PAINT VlSCOSIM_R

Be sure the surface to be sprayed is dry f'_

and free of all dirt, grease, oil and loose 0

paint Mix and prepare paint in" accor-

dance with the manufacturer's instruc-

tions. Strain material to be sprayed .

through a 60 to 90 mesh screen or ='_"_

equivalent

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.SL The

use of an air regulator assures clean, dry air.

B. Turn needle adjustment screw (18) out until first

thread shows This places the tip and needle ina full

open position which gives maximt,m tip and needle

life. Never turn all the way in, as triqqer cam will

break.

C. Turn fan adjusting screw (1) out until first thread

shows

D. Press trigger and adjust needle adjt, sting screw (18)

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 (I) 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

CONTROLLING THE FAN SPRAY

(Figure 2) The fan spray for an exter-

nal mix nozzle set up is easily con-

trolled by means of the fan adjusting

screw (1) By turning to the right

(clockwise) until it is closed will give

a rounded spray; turning it to the left

(counterclockwise) will widen the

spray into a fan shape of any width

desired The direction 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 (24) Tighten only fin-

ger tighL Do not use pliers or wrench

to tighten or loosen

HORLZONTAL FAN

VERTICAL FAN

FIGURE2

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 (18). 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

is recommended. This distance can be varied depending

on the item being sprayed, the material or the air pres-

sure used Release the trigger at the end of each lateral

stroke while the gun isstill 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 becomes natural

To Clean Gun: Spray a small amount of clean solvent

through the gun Never immerse the gun in solvents as

this removes lubricants and dries out the packings A

caustic solution should net be used to clean gun, as this

will destroy the aluminum alloy Remove air nozzle (23)

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 A

will result in distortion of spray pattern. Wipe U

exterior of gun with solvent soaked cloth

Never soak gun in liquid detergent ROUND

To Lubricate gun: After each day's use

place a drop of oil at trigger screw (9), fan

control packing (3), and fluid needle pack-

ing (12), Occasionally remove fan control

spring (5) and recoat with a light grease or

Vaseline.

MAINTENANCE

Proper adjustment of your Craftsman Detail Touch-Up

Gun will give you a normal spray pattern of this shape

(see illustration) If not, consult service check list on next

page,

Overlap each stroke 50%. This is done by aiming the gun

at the edge of the last stroke. A short practice period will

be necessary to achieve an even stroke. Avoid arching

the gun as this will leave an uneven coat of paint (see

illustration).

DON'T ARC

NOTE: If water is used as a solvent clean the gun, spray

paint thinner or mineral spirits through the gun after

cleaning to remove any excess moisture and protect

parts

CLEANING AND PREVENTIVE MAINTENANCE

Preventive maintenance should head off some problems

commonly encountered. Remember your detail touch-

up gun is precision engineered and proper maintenance

can help you get the fine quality results you desire

TROUBLESHOOTING GUIDE

PROBLEM

Heavy top or bottom

Pattern' _) i i

Heavy right or left side

)attern. ql i'

CAUSE

Material build-up on air cap or fluid

tip Partially plugged horn holes,

center holes or fluid tip hole_

CORRECTION

Determine where material build-up is by invert-

ing cap and test spraying If pattern shape stays

in same position, the condition is caused by

material 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 damages holes and distorts its spray pat.-

tern.
