Cleaning And Care - Sprayit 527 Guia De Inicio Rapido

Thin paint or material to be sprayed
according to directions on the container,
or ask your dealer. If spraying pressure is
low additional thinning may be required,
but add thinner sparingly.
Fill paint cup approximately 3/4 full.
Adjust spray pattern by spraying on a
piece of newspaper or cardboard. Begin
with fluid adjustment knob screwed in
(fully closes) and, if gun is being operated
from a tank type compressor or an air
line, set regulated air pressure to spray
gun at a nominal 25 to 35 psi and raise
only if paint is not adequately atomized
but do not use over 50 psi.
Test spray pattern by holding gun
stationary and by triggering a short burst
of paint at a distance of 6 to 10 inches.
See figure one. Very thin or fast drying
materials are sprayed at closer range
than heavier slower drying materials.
Gradually open fluid adjustment knob
until desired amount of material is
delivered. If sufficient material delivery
cannot be obtained, material must be
thinned further or spraying pressure must
be increased. The general pattern shape
is predetermined by the air cap and the
final pattern adjustment is made by the
fluid adjustment knob or by adjusting the
spraying pressure.
The proper fan spray pattern is the even
pattern as Shown in figure 1. The center
of the pattern has an even distribution of
paint which should gradually taper off at
the top and bottom edges. If the pattern
has a "heavy center" the material being
sprayed must be thinned further or the
spraying pressure must be increased. If
the spray pattern is heavy at the top or
the bottom of the pattern the air cap used
is partially clogged and must be cleaned
throughly.
2.Heavy Pattern
1.Even Pattern
Practice spraying with the spray gun to
get the proper feel and stroke (see figure
2). The spray pattern on each pass or
stroke should overtap approximately
onehalf on the previous pass or stroke. Do
not attempt to obtain complete coverage
with one stroke of the gun. Two ormore
light coats of paint are much better than
one heavy coat.
Do not stop the motion of the spray gun
while stroking. The path of the spray gun
English

must pass beyond the area being painted and the flow of the paint
must be triggered on and off as the spray gun passes into and out of
the spraying area. Stopping the motion of the spray gun or swinging
into a new stroke pattern while paint is being delivered from the spray
gun will result in heavy paint build-up at the edges of the stroke.
If the paint sags or runs or has heavy streaks in the direction of the
stroke, the spray gun is too close to the work, too much material is
being delivered, too much paint is being applied on a single stroke or
overlapping technique is improper. If there is excessive "fogging" of
spray mist being blown away from the work, the spray gun is being held
too far from the work surface.
Do not immerse gun in cleaner when cleaning as this will dissolve all
lubrication and dry out the packings, causing greatley accelerated gun
wear and packing deterioration.
Shut off air pressure to gun and remove fluid cup. Pull gun trigger and
let material in gun and fluid tube drain into cup. Wipe excess paint from
underside of fluid cup cover and fluid tube with cleaner soaked rag.
Pour paint from cup into storage container and throughly clean cup
with cleaner. This is best accomplished by pouring a small amount of
cleaner in cup, placing palm of hand over cup opening and shaking
vigorously. Wipe external cup threads clean with cleaner soaked rag.
Pour a small amount of cleaner into clean cup and assemble to spray
gun. Open fluid control knob fully and spray cleaner through gun while
shaking gun and cup vigorously to allow surges of air to come through
spray gun passages. The cleaning spray can be collected to keep it
from dispersing quite easily by spraying into a cardboard box or into
a bundle of old rags held close to the air cap. If cleaner in gun cup
becomes dirty replace with a small amount of fresh cleaner and repeat,
flushing procedure until cleaner sprayed through spray gun is clean.

Remove air cap and clean throughly using footpick or broomstick
straw if needed, but never use metal objects or wire. Wipe fluid tip and
exterior of gun clean with cleaner soaked rag.
Shake excess cleaner from cup and spray gun. If gun has been cleaned
with water or if it is to be stored for a long period of time, spray a
small amount of thinner and oil mixture through the gun. Always, after
3.Heavy Bottom
cleaning place a drop of oil of the fluid needle where it enters the
Pattern
Fluid needle packing screw and trigger the gun several
Times without air pressure. This will work the oil into the needle packing
and keep it soft and serviceable. An occasionable lubrication light
grease, vaseline or oil of all other adjusting knobs and friction points
will keep the gun working smoothly.
Readjust fluid needle packing screw each time gun is used. Replace
packing when paint leak cannot be stopped by tightening packing
screw.
