2Eastwood Technical Assistance: 800.343.9353 >> [e-mail]
The EASTWOOD CONCOURS®LT100 HVLP PAINT GUN has all the features of a professional paint
gun with the added benefit of a specific, low air demand design requiring only 4.5 CFM [120 l/min]
@ 30 PSI [2 Bar]. It is precision engineered, capable of producing a high-quality paint finish and ideal
for the seasoned professional or hobbyist. The body is constructed of a highly durable diecast alloy
with Stainless Steel internal components which are compatible with both solvent and waterborne
coatings. Convenient reference markings on the gun body and control knobs allow for accurate
repeatability of gun settings.

READ INSTRUCTIONS
• Thoroughly read and understand these product instructions before using this
equipment. Failure to follow all warnings can result in tool damage or serious
physical injury.
• Keep these product instructions for future reference.
FIRE AND EXPLOSION HAZARD!
• Do Not use near sparks, open flame or another potential ignition source.
Solvents and paints are highly combustible and may ignite or explode.
Keep at least 25’ away from any non-explosion proof compressors, motors,
switches etc.
HEALTH HAZARD!
• Avoid breathing vapors produced by Spray Gun. Always wear appropriate
NIOSH approved breathing apparatus and use in a well-ventilated area.
• Wear appropriate ANSI standard Z87.1 eye protection.
• Wear solvent-resistant gloves.
• Do not allow unprotected persons or pets in the spray area.
BURSTING HAZARD!
• Do not exceed 60 psi (4.1 bar) of air inlet pressure. Permanent paint gun
damage and/or bursting could occur and cause personal injury.
DANGER indicates a hazardous situation which, if not avoided, will result in death or serious injury.
WARNING indicates a hazardous situation which, if not avoided, could result in death or serious injury.
CAUTION used with the safety alert symbol, indicates a hazardous situation which, if not avoided,
could result in minor or moderate injury.
NOTICE is used to address practices not related to personal injury.
SAFETY INFORMATION
The following explanations are displayed in this manual, on the labeling, and on all other information
provided with this product:

INJURY HAZARD!
• This Paint Gun can accidentally spray when handling while connected to an
air supply causing serious personal injury. Always disconnect the Paint Gun
from the air supply before adding paint, changing nozzles, removing clogs or
other maintenance.
• Use only Eastwood Aerosol Injected Cleaner, Eastwood Paint Gun and Equip-
ment Cleaner, acetone or lacquer thinner to clean guns. Use of chlorinated or
halogenated hydrocarbon solvents can corrode aluminum gun components
or emit hazardous reactive gasses.
• Use for spraying paint products only. Do not use for spraying pesticides,
fertilizer, acids or other corrosive materials and solvents.
SAFETY INFORMATION
SET-UP
• Remove all components from carton, identify them and become familiar with their purpose.
• Before use, it is necessary to thoroughly clean out the paint cup as well as the paint gun air
and paint passages with a solvent such as Eastwood PRE, Eastwood Aerosol Injected Cleaner,
Eastwood Paint Gun and Equipment Cleaner or acetone. This is to remove any residual manu-
facturing oils or impurities that may remain. Dry thoroughly.
• A 3/8” I.D. minimum air hose at a 25’ maximum length is strongly recommended for best
results. Smaller I.D. hose and greater length may reduce available CFM and produce unsatis-
factory results.
• A clean, dry, regulated air supply is required. An Eastwood #31633, Eastwood Air CFS, or
equivalent works well.
• To avoid pulsation of pressure when the trigger is depressed, an optionally available, remotely
mounted, main regulator should be set to approx. 40 PSI [2.75 bar] and an optional “on the
gun” regulator (an Eastwood #31834 Concours Pro Regulator works perfectly), initially set to
30 PSI [2 bar], is then used for fine-tuning of gun pressure.

ASSEMBLY
• Insert the Paint Cup Inlet Filter into
the inlet at the top of the Gun Body
(FIG 1).
• Thread the Gun Cup onto the
threaded inlet at the top of the Gun
Body. Hand Tighten only (FIG 2).
• The Paint Gun is now ready for use.

IMPORTANT NOTES BEFORE PAINTING
1. Please note that many variables affect the adjustment of a paint gun including paint viscosity
and type, atmospheric conditions such as humidity, barometric pressure and temperature, as
well as air inlet pressure and operator preference. Always “tune” the gun before each use as
prevailing conditions may not be the same as the previous use.
2. It is always best to test spray on sheets of cardboard or masking paper with the actual paint
you will be applying while making your adjustments to become familiar with the gun and
achieve the ideal Fluid Control Setting.
3. Remember that a small amount of product wasted at this point can avoid disappointment in
your results and the need to re-do your work later.

• Air Cap - Make sure the Air Cap is properly oriented in a horizontal plane to produce a vertical
fan spray pattern by viewing the HVLP Paint Gun from the front. To adjust, loosen Retaining Ring
by rotating counter-clockwise slightly, adjust Air Cap then re-tighten Retaining Ring (FIG 3).
• Fluid Control – The Fluid Control knob (located at mid-rear of gun body) regulates the distance
the Needle travels and the amount of paint flowing through the gun. NOTE: Generally, for higher
viscosity coatings, a wider opening is desired while a closer opening is better suited for lower
viscosity fluids. To adjust, rotate the Fluid Control Knob outward (counter-clockwise as viewed
from the rear) to increase flow and turn inward to reduce flow (FIG 3).
• Fan Control – The Fan Control knob (located at the upper-rear of the paint gun body) controls
the size and shape of the spray pattern of “fan”. Rotating the knob counter-clockwise (as
viewed from the rear of the gun) will produce a larger and softer spray pattern while rotating it
clockwise will result in a smaller, sharper, round pattern. For most painting conditions, a larger,
softer fan is desired (FIG 3).

• Air Control – The Air Control knob (located at the bottom of the gun handle adjacent to the
air inlet) is opened by rotating in a counter-clockwise direction (as viewed from the bottom of
the gun). This is for “fine tuning” the airflow to the gun. You will generally want to set the inlet
pressure at the regulator, start with the Air Control in the fully open position and decrease air
as needed (FIG 3).
• With practice, you will quickly acquire a “feel” for the
gun and will be producing professional results.
• After achieving optimal knob settings, note their
positions with the numbered indicators on the face of
the knobs. This will assist in quickly “tuning” the gun
in future uses (FIG 4).
GUN CLEAN-UP
• Disconnect air supply to gun.
• Pour unused coating into a proper disposal container, then remove Paint Cup.
• Wipe out any excess coating then thoroughly rinse the Paint Cup with a mild solvent compatible
with the coating being used.
• Attach Paint Cup, then pour a small amount of a solvent compatible with the paint being used
into the Cup, then run solvent through HVLP Gun in a safe area until it flows clear.
• Remove air supply from HVLP Gun.
• Pour out any unused solvent and remove paint cup.
• Allow solvent to dry completely from all components.
As an alternative, #12846Z Eastwood Aerosol Injected Gun Cleaner and
#16154ZP Eastwood Paint Gun and Equipment Cleaner are excellent for
this purpose.
