Unpacking
Remove the components from the box. Inspect for concealed damage and/or missing
items. If you discover any damage and/or missing pieces, contact your distributor
immediately.
Your 3M™ Pressure Feed HVLP & LVLP Spray Gun Kit includes:
• Spray Gun
• Care Kit
• Cup (optional)
3M™ Series 10 & 14 HVLP Spray Guns
The 3M™ Series 10 & 14 HVLP Spray Guns are non-bleed
spray guns with a composite body construction, 10 cfm air
consumption, 1:1 reduction ratio, 3/4” air inlet connection:
10 psi maximum inlet air pressure*, for use with either
compressed air systems or turbines equipped with a pressure
relief mechanism. Air stops flowing through the series 10 & 14
spray guns when the trigger is fully released.
3M™ Series 11 & 15 HVLP Spray Guns
The 3M™ Series 11 & 15 HVLP Spray Guns are bleeder
spray guns with a composite body construction, 10 cfm air
consumption, 1:1 reduction ratio, 3/4” air inlet connection:
10 psi maximum inlet air pressure*, for use with turbine air
systems only. The series 11 & 15 spray guns are a free flow
design, which allows air to flow through the spray guns even
after the trigger is released.
3M™ Series 12S HVLP Spray Gun
The 3M™ Series 12S HVLP Spray Gun is a non-bleed
spray gun with a composite body construction, 10 cfm air
consumption, 6:1 reduction ratio, 1/4” air inlet connection: 60
psi maximum inlet air pressure*, for use with compressed air
systems only.
* Maximum inlet pressure will yield approximately 10 psi at the air cap.
Spray Gun Overview
3M spray guns were designed from the inside out for the effective, efficient, economical
application of paints, adhesives, coatings and finishes. These spray guns deliver large
spray patterns with very low overspray. The soft, tight, adjustable pattern with complete
atomization results in a high finish quality and absolute control. Each light weight
spray gun is designed for easy handling, reliability and durability and for minimum
maintenance costs.
Whether your air source is compressed air or a turbine unit, you will benefit from the
speed of application, the decrease in masking, sanding and cleanup time and the
ability to achieve a fine finish. Combine your 3M spray gun with the 3M™ PPS™ Paint
Preparation System and enjoy additional savings of time and cleaning solvents.
3M equipment is for professional use only. Hazards can occur from equipment misuse.
Any misuse of the equipment or accessories, such as over pressurizing, modifying
parts, using incompatible chemicals and fluids, or using worn or damaged parts can
cause serious bodily injury, fire, explosion or property damage. Please read and follow
all Safety Statements and Instructions.

Adjusting the Fluid Flow
The fluid flow can be adjusted by using
the needle adjustment screw as noted
in Fig. 1. As a starting point, gently turn
the knob clockwise until you have very
little needle travel (pull trigger to verify).
Do not over-tighten. After the needle
travel has stopped, further tightening will
only serve to compress the spring and
will not aid in adjustment. Next turn the
knob counterclockwise two full turns.
These adjustment procedures will serve
only as a starting point. Fine tuning of
these adjustments will be based on your
material and technique.

body construction, 10 cfm air consumption, 6:1 reduction
ratio, 1/4” air inlet connection; 60 psi maximum inlet air
pressure*, and the ability to spray organic and inorganic zinc
materials. All wetted parts are made of a non-stick composite
material with graphite packing.
3M™ Series 19 HVLP Spray Gun
The 3M™ Series 19 HVLP Spray Gun is a non-bleed spray
gun with an aluminum body with a non-sticky, 10 cfm air
consumption, 4.3:1 reduction ratio, 1/4” air inlet connection:
43 psi maximum inlet air pressure* for use with compressed
air system.
3M™ Series 19C LVLP Spray Gun
The 3M™ Series 19C LVLP Spray Gun offers the same
features of the 3M™ Series 19 HVLP Spray Gun with an
aluminum body with a non-stick, solvent resistant finish,
4.5 cfm air consumption, 4.3:1 reduction ratio, 1/4” air inlet
connection: 43 psi maximum inlet* air pressure and the added
benefit of low cfm air consumption allowing for use with even
small portable air compressors.
Contents cont.
* Maximum inlet pressure will yield approximately 10 psi at the air cap.

Relieve the pressure from the spray
gun and cup before servicing.
1. Turn off the air supply to the
spray gun.
2. Disconnect air line from the
spray gun.
3. Pull trigger to return mix to spray
gun cap.
General System Maintenance
Do not immerse the spray gun in solvent.
Spray Gun Care and Cleaning
Do not wipe the spray gun with a cloth
soaked in solvent; ring out the excess.
Note: Your spray gun may be made
from aluminum and may contain
aluminum components. Certain
solvents containing Methylene
Chloride and Tricloromethane are
not chemically compatible with
aluminum.
Read, understand and follow all
safety statements as well as wear
appropriate, approved personal
protective equipment per the
applicable MSDS and material
container labels for cleaning
solutions.
You must lubricate the moving
components after every cleaning of the
spray gun. Cleaning washes away the
lubricants that protect the friction points.
Use an appropriate lubricant such as
petroleum jelly.
Do not use metal tools to clean the air
cap holes as this may scratch them;
scratches can distort the spray pattern.
Do not point the spray gun up while
cleaning it.

Fan Adjustment Knob
Adjusting the Fan Pattern Size
The fan size is regulated by the fan
adjustment knob as noted in Fig. 2.
As a starting point, gently turn the
knob clockwise until you feel no
further adjustment. Next, turn the knob
counter-clockwise one full rotation. The
fan adjustment will allow you to spray
from a small round to a full fan pattern.
The pattern can also be changed from
vertical to horizontal by rotating the air
cap a ¼ turn.
General Set Up and Spray Gun Use cont.

RIGHT
Spray Technique
1. To achieve the best results when
spraying material, keep the spray
gun perpendicular to the surface and
maintain a consistent distance of
approximately 6 to 8 inches
(160-200 mm) from the object being
sprayed.
2. Use smooth, even strokes across the
surface to be sprayed with 50% over-lap.
3. Paint using parallel strokes. This
technique applies all coatings evenly
without cross coating.
Horizontal Pattern
Vertical Pattern
Right
90º 6” - 8”
Note: The small round pattern can
be achieved by closing down the fan
adjustment, triggering the gun lightly,
and maintaining a distance from your
target of 2 to 4 inches (50-100 mm).

11. Thread fluid needle tip on finger
tight. Pull trigger back and hold
while you install the fluid nozzle with
the gun wrench. Tighten the nozzle
securely to obtain a good seal.
12. Install the retaining ring and air cap.
Spray Gun Care and Cleaning cont.
10. Scrub the retaining ring, air cap and
fluid nozzle with a soft-bristle brush.
To clean out air cap holes, use a
small brush. Clean the air cap and
fluid nozzle after each use. Do not
soak the retaining ring in solvent for
prolonged periods of time.
13. Dampen a soft cloth with solvent
and wring-out the excess. Point
the spray gun down and wipe off
the outside of the spray gun.
9. With the spray gun pointed down,
clean the front of the spray gun,
using a soft-bristle brush and
solvent.
8. Dip the end of a soft-bristle brush
into a compatible solvent. Do not
continuously soak the brush’s bristles
with solvent, and do not use a wire
brush.

ATTENTION
Solvent left in the spray gun air
passages could result in a poor quality
paint finish. Do not use any cleaning
method which may allow solvent into the
spray gun air passages. Do not expose
air regulators and gauges to solvent as
damage may occur.
Cleaning Process
1. Relieve the pressure from the spray
gun and cup before servicing.
2. Refer to your cup or fluid source
manual for removal and cleaning.
3. To retain unused material or
temporarily store mixed material,
see your Local, State, Federal and
OSHA guidelines, along with material
manufacturer’s recommendations for
storage.
4. Flush the spray gun. To flush spray
gun, run water or compatible and
compliant solvent into the spray gun
fluid passage while triggering the
spray gun.
Spray Gun Care and Cleaning cont.
5. Remove the retaining ring and air cap.
6. Pull trigger back and hold while
removing the fluid nozzle from the
spray gun with the gun wrench.
Note: This prevents damage to the
needle tip and fluid nozzle.
Clean the fluid and air line filters daily.
Check for any fluid leakage from the
spray gun and fluid hoses.
Flush the spray gun before changing
colors and when done operating the
spray gun.
