Preparation (Continued)
E
If the spray is too fine (excessive
N
overspray), caused by too much air for
G
the amount of paint being sprayed,
reduce the air pressure or open the fluid
L
control to spray more material.
I
S If the spray is too coarse (spitting globs),
reduce the amount of material with the
H
fluid control knob or thin the material.
NOTE: If there is sagging, too much
material is being applied. If there is an
"orange peel" effect, the material is too
thick.
Before spraying the workpiece, practice
a few minutes on a cardboard target to
ensure the pattern consistency and size
are set correctly.
DISTANCE ADjUSTMENTS
Start 6 inches away from work surface.
If pattern begins to run, move back
an inch and try again. The pattern will
be dry and thin and may feel rough if
sprayed from too far away.
SPEED OF STROkE ADjUSTMENTS
If speed of stroke is too slow, paint will
be wet on work surface and may run. If
speed of stroke is too fast, paint will be
dry and uneven on work surface.
WATER / OIL IN COMPRESSED AIR
All compressor pumps discharge some
condensed water, oil or contaminates
with the compressed air.
ImPORTANT: This condensation will
cause "fish eyes" to appear in the
paint job. Install appropriate water/oil
removal equipment (such as filters and
dryers) and controls as necessary for
the intended application.
Failure to install
appropriate water/
oil removal equipment may result in
damage to machinery or workpiece.
Spray Guns
®
Operation
1. Begin spraying. Always keep the
gun at right angles to the work by
flexing your wrist while making the
paint stroke (See Figure 9).
Figure 9
NOTE: Do not keep the wrist stiff
during the stroke and do not "fan" the
gun from side to side in an arc while
spraying. This type of motion brings the
gun close to the surface and deposits a
heavy concentration of material in the
center of each stroke and applies an
insufficient concentration of material
at the end of the stroke. This will make
a very poor, irregular paint job (See
Figure 10).

Keep the nozzle about 6 to 9 inches
from the work surface throughout
the stroke and always keep the gun in
motion while spraying. Stopping gun
movement in mid-stroke will cause
a build up of material and result in
"runs."
2. "Trigger" the gun properly. Start
the gun moving at the beginning
of the stroke BEFORE SQUEEZING

THE TRIGGER and release the trigger
BEFORE STOPPING GUN MOVEMENT
at the end of the stroke. This
procedure will "feather" (blend)
each stroke with the next without
showing overlap or unevenness (See
Figure 11).

3. The amount of material being
applied can be varied by the speed
of the stroke, distance from the
surface and adjustment of the fluid
control knob.
4. Overlap strokes just enough to
obtain an even coat (See Figure 12).

5. Use a piece of cardboard as a shield
to catch overspray at the edges of
the work to protect other surfaces.
Use masking tape to cover other
areas if needed.
NOTE: Two thin coats of material will
yield better results and have less chance
of runs than one heavy layer.
