GUN SETTINGS
• 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 A).
• Fluid Control – The Fluid Control knob (located at top 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 A).
• Fan Control – The Fan Control knob (located at the upper left side of the paint gun body) con-
trols the size and shape of the spray pattern of “fan”. Rotating the knob counterclockwise will
produce a larger and softer spray pattern while result in a smaller, sharper pattern. For most
painting conditions, a larger, softer fan is desired (Fig A).
• 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 form 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 full open position and decrease air as
needed (Fig A).
• When you have achieved your optimal knob settings, note their positions with the indicators on
the gun body and knobs. This will assist in quickly “tuning” the gun in future uses.
• With practice, you will quickly acquire a “feel” for the gun & will be producing professional results.
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.
CLEAN-UP
• Disconnect air supply to gun.
• Remove Paint Cup and pour unused coating into proper container.
• Wipe out any excess coating, then thoroughly rinse the Paint Cup with a mild solvent compatible
with the coating being used.
• Pour a small amount of a solvent compatible with the paint being used in the Paint Cup then
attach Paint Cup, reconnect air supply then spray solvent through HVLP Gun in a safe area
until it flows clear. Note, as an alternative, #12846Z Eastwood Aerosol Injected Gun Cleaner is
excellent for this purpose.
• Remove air supply from HVLP Gun.
• Pour out any unused solvent and remove paint cup.
• Allow solvent to dry completely from all components.
