SPRAYING
1. Stir the spraying material thoroughly before measuring viscosity.
2. Dip the viscosity test cup completely into the spraying material.
3.Hold the test cup up and measure the time in seconds until the liquid empties out.
This time is referred to below as Runout Time (DIN-s).
THINNING CHART
Material Viscosity (DIN-s)
1) Solvent containing gloss paints 15-50
2) Primers 25-50
3) Mordants Undiluted
4) Clear varnish 15-40
5) Water-dilutable gloss paints 20-40
6) Motor-vehicle enamels 20-40
7) Wood preservatives Undiluted
Material to be sprayed should always be strained to remove
any impurities in the paint which may enter and clog
the system. Impurities in the paint will give poor performance
and a poor finish.
MATERIAL FLASH POINT MUST BE 70°F (21°C) OR HIGHER.
Fill Container
1. Unscrew the cup from the spray gun.
2. After the material has been properly thinned and strained, fill the container
to the top of the neck.
3. Carefully screw the cup back onto the spray gun.
The spray pattern adjusting (See Fig.C).
The spray pattern shape is adjusted by turning the ears of the air cap (2) to either
the vertical, horizontal, or diagonal positions. The positions of the air cap (2) and
the corresponding spray pattern shapes are illustrated.
Test each pattern and use whichever pattern is suitable for your application.
NEVER trigger the gun while adjusting the ears on the air cap.
NEVER point the spray gun at any part of the body.
Material flow adjustment (See Fig.C)
Set the material volume by turning the regulator (3) behind the trigger of the spray
gun.

CLEANING
Proper Spraying Technique.
If spraying with an HVLP spray system is new or unfamiliar to you,
it is advisable to practice on a piece of scrap wood or cardboard before
beginning on your intended workpiece.
Surface preparation
All objects to be sprayed should be thoroughly cleaned before spraying material
on them. Areas not to be sprayed may, in certain cases, need to be masked or
covered.
Spray area preparation - outdoor use only
The spray area must be clean and free of dust in order to avoid blowing dust onto
your freshly sprayed surface.
How to Spray Properly (See Fig.D)
• Position the spray gun perpendicular to and 5 -15 cm. from the spray surface,
depending upon the spray pattern size desired.
• Spray parallel to the surface with smooth passes at a consistent speed as
illustrated. Doing this will help avoid irregularities in the finish (i. e. runs and sags).
• Always apply a thin coat of material on the first pass and allow to dry before
applying a second, slightly heavier coat.
• The closer your sprayer is to the object being sprayed the lower the overspray.
• When spraying, always trigger the spray gun after spray pass has begun and
release trigger before stopping the pass. Always keep the gun pointed squarely
at the spray surface and overlap passes slightly to obtain the most consistent
and professional finish possible.
Special cleanup instructions for use with flammable solvents
(must have a flashpoint above 70°F (21°C):
• Always flush spray gun outside.
• Area must be free of flammable vapors.
• Cleaning area must be well-ventilated.
1. Turn off device. Open trigger so that the coating material in spray gun runs
back into the container.
2. Unscrew the container. Return remaining coating material into the material can.
3. Clean the container and ascending pipe with a brush.
4. Fill the container with solvent or water. Screw container back in place.
Turn on device and spray the solvent or water into a container. If a tube is not
used, some solvent or water will be deposited outside the container.
This is due to the high air volume.
