IMPORTANT: Before using this equip-
ment, read all safety precautions and
instructions. Retain for future use.
DESCRIPTION
The MSA-510-DEC is a smaller, lighter
weight gun that can apply decorative
spatter effects to wood furniture, metal
panels, etc. Finish may be changed
from a fine mist to larger droplet size
particles. Simply adjust fluid pressure
and/or air pressure
The MSA-510-DEC comes with the
flat-end AV-447 spatter cap assembly.
Small spatter dots are the result of
coarse atomization when using the
standard spatter cap assembly (2).
OPERATION
Note
This gun may be used with
chlorinated solvents. Alumi-
num is not used in the fluid
passage areas.
Mix material according to manufacturer's
instructions. It may be necessary to strain
material.
A greater than normal gun distance
provides a more uniform particle size.
Particle spacing is determined by speed
of movement and degree of overlap.
Particle size is dependent on the mate-
rial consistency. Specially formulated
spatter materials are available, although
standard paints may be used. Apply
standard paints using very little or no
reduction.
Pressure on cup or tank controls mate-
rial flow. Begin with the adjusting
screw (31) wide open. Use adjusting
screw (31) to regulate material flow
under abnormally low material pres-
sure or material viscosity conditions.
SERVICE BULLETIN
MSA-510-DEC DECORATOR SPRAY GUN
Replaces SB-2-319-B
Repair Kit KK-4987-2
Adjust atomization air to get desired
particle size. It should be high enough
to carry particles to surface. Spatter
dot size increases with pressure reduc-
tion, and decreases with pressure in-
crease. Pressure used depends on
material viscosity being sprayed and
desired operation speed.
PREVENTIVE MAINTENANCE
To clean gun passages, blow back
paint to material supply source and
flush fluid passage with clean solvent.
Model HD-503 Gun/Hose Cleaner is a
very fast and effective way of cleaning
(See Accessories). Wipe gun clean
with solvent soaked cloth.
If slots of ring (4) become clogged,
clean by soaking cap in solvent and
scrubbing with a gun cleaning brush.
Note
When replacing the fluid tip or
fluid needle, replace both at
the same time. Using worn
parts can cause fluid leakge.
Also, replace the needle pack-
ing at this time.
Using SSL-10 gun lube, lightly lubri-
cate the threads of the fluid tip before
reassembling. Torque to 20-25 ft. lbs.
To prevent damage to the fluid
tip (7) or fluid needle (28), be
sure to either 1) pull the trigger
and hold while tightening the
fluid tip or 2) remove fluid
needle adjusting screw to re-
lieve spring pressure.
