AIRLESS
ELECTRIC PAING SPRAY GUN
AIRLESS
PPAINT SPRAYING is the most efficient way of applying paint.
The spray gun is ideal for small, diverse painting jobs. Airless
paint spraying is more ideal than conventional methods because
of its ability to atomize paint from its liquid form. The
term "atomize" means to separate into the smallest
parts.
The gun transforms paint
into tiny droplets and propels these droplets at high velocity.
Atomization ensures uniform coverage even in delicate and
hard-to-reach work areas, and on rough or uneven surfaces.
You will find painting with the gun simplifies the unreliability
of aerosols, and the tedium of brush or aerosol painting.
PREPARING MATERIAL FOR SPRAYING
THINNING
|
1.
|
Paints are generally made for brush or roller application.
Very often, thinning is necessary for proper atomization
and good coverage when spraying. |
|
2.
|
Thorough and frequent stirring often improves the
ability of the paint to be sprayed. If limps or "skin"
still appear after stirring, try straining the materials
through a piece of cheesecloth, a 60-mesh paint strainer,
or an old nylon stocking to insure a smooth finish.
(Note: Be sure the paint strainer located on the end
of the sprayer pump tube is in place at all times.)

|
Check manufacturer's label for the specific type of
thinner required
|
|
4.
|
Paints vary greatly in thickness, so no general thinning
ratio applies to all types. However, the ratios listed
are good approximations:
| Oil-base
interior enamel |
1
part solvent to 4 parts paint |
| Outdoor
oil-base |
1
part solvent to 3 parts paint |
| Lacquers |
1
part solvent to 2 parts lacquer |
| Stains
& Varnishes |
Generally
no thinning required |
|
TESTING
|
1.
|
Test the spray pattern on a piece of old cardboard or
wood. If a poor pattern results, check paint thickness
or adjust the Adjustment Knob located above the handle
of your spray until you get the best spray pattern possible.
Then try spraying at different distances from the cardboard,
until you find the distance that gives you the best-looking
results. |
|
2.
|
Dip the viscometer cup into your spray-tested mixture
until it is filled. Withdraw the cup quickly to a
height of one to two inches above the liquid, and
then start timing. Watch the stream until the solid
stream breaks at the base of the cup, and then stop
timing. Paint should drip through the cup in 10-12
second intervals. Any paint that drips at a thicker
rate of 12 seconds will damage the spray gun.

Review
your test spraying results to determine if thinning
or thickening is required. Correct mixture accordingly
and retest spray pattern.
- Once the proper sprayable mixture has been obtained,
recheck your viscosity cup flow time and write it on
the paint can. This is your control for mixing additional
amounts of paint as you may require at a later time.
- This spray gun is not to be used with Latex paint.

SPRAYING
|
1.
|
After preparing the painting surface wipe off the surface.
Oil, dirt or wax left unmoved can cause pinholes and
poor paint adhesion. |
|
2.
|
Stir material, pour it into sprayer jar, attach the
jar, and plug your sprayer into an AC outlet of the
same voltage and current as that specified on the
sprayer.
|
|
3.
|
Check to see if you have enough material in the jar
to cover the end of the pump tube. If there is not
enough material, the sprayer will operate erratically
and make an unusually loud buzzing noise.
|
|
4.
|
Maintain the predetermined distance between you and
the object at all times. Start spraying. If you are
standing too far away from your object, a sandy, pebbly,
pitted, pocked, or "orange peel" appearance
will result. If you are standing too close to your
object , pinholes will result.
|
|
5.
|
Keep the sprayer moving parallel to the object. Sags
or curtains can result if you spray too much material
in one spot.
|
|
6.
|
Do not spray lacquer in a damp, humid or cold atmosphere,
or a whitish cast will appear on your object. If you
must spray, add retarded to you lacquer.

CLEANING
AND MAINTAINANCE
This
product has been quality engineered and tested to give long,
reliable service provided proper cleaning and preventative
maintenance is performed.
|
1.
|
Empty the spray jar and wash it thoroughly with the
recommended thinning solvent. Discard solvent. |
|
2.
|
Pour about 1 inch of solvent into the sprayer jar
and attach it to the sprayer. Splash the solvent around
in the jar to wash off exposed sprayer parts. Do not
turn upside down. Pull the trigger and spray the solvent
through the sprayer. Discard solvent.

FINISHING
UNPAINTED FURNITURE
Sand
thoroughly with fine sandpaper paying special attention to
exposed end grain. Fill any dents or imperfections in the
wood with wood putty, then sand level after it has dried.
Dust thoroughly, and wipe with a tack rag to remove any remaining
specks of dust. If the piece is to be enameled, apply a sprayed
coat of shellac or other sealer first. After this has had
time to dry completely, sand very lightly with a fine paper,
dust, and spray with enamel.
For
a stained and varnished finish, apply the stain first. Spray
a small area at a time, then wipe. With most stains, the longer
you leave them on, the darker the wood becomes. When the stain
has had time to dry thoroughly, follow with spray-coats of
shellac or varnish, sanding with 6/0 garnet paper between
coats.
SPARYING
RADIATORS
Spray
painting radiators lets you cover those hard-to-reach places
that brushes just don't seem to reach. Most any type of interior
paint or enamel can be used (except kalsomine or casein paints)
Make
sure the radiator is clean and cold before spraying. After
spraying, make sure the paint is dry before turning on the
heat.
WINDOW
SCREENS
This
is one of the may chores where using a sprayer: takes the
paint out of painting." Here is how to go about it. Stand
your screens upright, "stacking" them 3 or 4 deeps.
Using screen paint or spray varnish, spray the stack of screens
first from the front and then from the back. (Masking the
frames is unnecessary if they also are to be painted because
paint or varnish that gets on them during spraying can be
covered later.) When the screens have dried completely, mask
the mesh with newspaper held in place with masking tape. Properly
prepare any good grade of thinnable house paint or trim color,
and spray the frames.
TIPS
ON SPECIAL PAINTING JOBS
SPARYING ROUGH, INTERICATE, HARD- TO-REACH SURFACES
Using
a brush or roller to paint shutters, redwood fencing, highly
detailed furniture and other intricate surfaces would be a
nightmare. But with the gun you can paint these seemingly
unpaintable surfaces quickly and easily and get professional
results every time. Just thin your spraying material properly,
pour it into the sprayer jar, attach the jar and spray. You
can paint crack and crevices, as well as smooth areas, quickly
and thoroughly. So jobs that normally take hours now only
take minutes.
MULTICOLOR
PAINTING
If
your project calls for more than one color, decide which color
is to be painted first, cover the other part with newspaper
held in place with masking tape, and spray the first color
on. After the first color is completely dry, cover this colored
section with newspaper held in place with masking tape, and
spray the second color on. Make sure the edge of the masking
tape meets the color dividing line exactly and evenly, and
that the edge is pressed down firmly so no spray can get under
it.
SPARYING SMALL FURNITURE
Before
spraying small pieces of furniture like tables and chairs,
place them in such a way that they are easily sprayable from
all necessary angles. First spray the undersides. After they
are completely dry, turn the piece right side up. Drive a
nail into each led of the furniture so there is about a one-half
inch clearance above the floor. Then spray the topside and
legs, saving the most prominent part of the project for last
(tabletops, chair seat, etc.).
