• Insert the other end of the air hose into
the hose connector of the front of the
power unit. A slight twisting action when
inserting the hose will help insure a snug
fit.
Material preparation
8.4
Viscosity
• The appliance can process spray materi-
als up to a maximum 150 DIN
ity). You can determine the viscosity
(thickness) of the substance with the
supplied measuring cup using a simpli-
fied measuring procedure.
• Before spraying, the material being used
may need to be thinned with the proper
solvent as specified by the material man-
ufacturer. Never exceed the thinning
advice given by the coating
manufacturer.
• Do not use materials with a flash point
below 21 °C. Follow the instructions
below.
Paint thinning
8.5
a. Stir the spraying material thoroughly
before measuring viscosity.
b. Dip the viscosity test cup (15) completely
into the spraying material.
c. Hold the test cup (15) up and measure
the time (in seconds) until the stream of
liquid stops. The resulting value is
referred to as DIN seconds (DIN
d. If the value is too high, gradually thin the
spray material by adding small amounts
of a suitable thinning agent in and mixing
the liquid.
e. Measure the DIN seconds again. Repeat
the process until you measure a viscos-
ity of less than 150 DIN seconds.
• Do not exceed the maximal viscosity of
the appliance. The spray material must
not be too thick. Otherwise, the appli-
ance might clog.
• Ensure that the spray material and thin-
ning agent are compatible. Using an
unsuitable thinning agent may cause
clots that clog the appliance. Never mix
synthetic resin varnishes with cellulose
thinners.
• Granular products and products contain-
ing solids must not be sprayed. Their
abrasive effect will shorten the service
life of the pump and valve.
• Material to be sprayed should always be
strained to remove any impurities in the
paint which may enter and clog the sys-
tem. Impurities in the paint will give poor
performance and a poor finish.

Fill container

(See Fig. G).
a. Unscrew the container (11) from the
spray gun.
b. After the material has been properly
thinned and strained, fill the container.
c. Carefully screw the container back onto
the spray gun.
ON / OFF SWITCH
8.7
The on/off switch is located below the han-
dle of the power unit.
• Press the switch button to turn on or turn
off the power unit.
Adjusting spray pattern shape
8.8
(See Fig. D).
The spray pattern shape is adjusted by
turning the air cap (2) to either a vertical,
horizontal, or diagonal position. The posi-
tions of the air cap and the corresponding
spray pattern shapes are illustrated (See
).
-s
Fig. D). Test each pattern and use which-
ever pattern is suitable for your application.
Material flow adjustment
8.9
Set the material volume by turning the
material adjustment knob (8).
Proper spraying technique
8.10
• 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 work piece.
a. Preparing the surface
• Carefully cover a large area around the
spray surface. Any surface that is not
masked could become contaminated.
• Ensure that the surface is clean, dry and
free of grease.
• Polished surfaces should be lightly
sanded and the sanding dust removed.
Material flash point must be 21 °C
or higher.
