(Original instructions)
Note : Always test the spray pattern on scrap cardboard
or similar material first. Begin with flow control knob on the
highest flow setting. If less flow is desired, dial the flow control
knob in. Heavier, thicker materials should be sprayed with the
indicator close to the (+) icon. Thinner materials should be
sprayed with the indicator close to the (-) icon.
Note : If the flow control setting is set completely to the
minimum side, the trigger will have limited or no travel. Back
the flow control knob off (clockwise) to allow for more trigger
travel.
Liquid material preparation (fig. J & K)
Note : Make sure the type of material you use can be cleaned
with either mineral spirits or paint thinner (for oil-based paints)
or a warm water and soap solution (for water soluble paints
like latex). Use drop cloths to protect your floors and anything
else in the spraying area that you wish to remain untouched.
The liquid being sprayed may need to be thinned (diluted)
before staring. When thinning, use the proper liquid thinner
recommended on the container by the material manufacturer.
Warning! Do not use materials with a flashpoint lower than
55°C.
Note : A mixing bucket (12) is provided to use when transfer-
ring spray material from the original container into the bucket
for thinning and measuring purposes (fig. J).
Note : A viscosity cup (13) is provided to determine the
“runout time” of the material being used.
u
Before measuring for the proper viscosity, stir the material
thoroughly.
u
Dip the viscosity cup (13) into the material being sprayed
and fill the viscosity cup (13) completely.
u
With the viscosity cup (13) held over the material con-
tainer, measure the amount of time it takes for the stream
of material flowing out to “break” or stop being a constant
stream out of the bottom of the viscosity cup (13) (2
minutes or less) (fig. K). This is the “runout time” Refer to
the thinning table for information on the thinning required
for different materials.
u
If material needs thinning, add the appropriate liquid thin-
ning material recommended by the manufacturer.
u
It is possible to spray latex paint with this unit, however,
the required thinning may exceed material manufacturer's
recommendation. Thin latex paint so that it runs through
viscosity cup (13) in under 2 minutes. The operator should
consider the type of application and final location of the
project when spraying a material that requires more than 2
minutes to run through the viscosity cup (13).

Hints for optimum use
Preparation tips
u
Always stir and strain the material thoroughly before use.
u
With any spraying job you should always ensure that
you have properly prepared the surface to get the best
finish. That is, all surfaces are free from dust, dirt, rust and
grease. Lightly pressure wash decks or exterior surfaces
and ensure that they are dry before spraying.
u
Even though HVLP sprayers have very little overspray,
it is recommended that you mask all edges and other
areas and use drop cloths to protect your floors and
anything else in the spraying area that you wish to remain
untouched.
u
Skin that forms on the top of paint can clog the sprayer.
Remove skin before mixing. Strain with a funnel with a
filter attached or through hosiery to remove any impurities
that could clog system.
u
Before starting have gloves, paper towels, rags etc. avail-
able for unexpected spills.
Developing the proper spraying technique (fig. L & M)
u
Practice spraying on a piece of scrap material such as
cardboard to test your spray pattern and become familiar
with the flow control feature of the sprayer.
u
Ensure surface to be sprayed is free of dust, dirt, and
grease.
u
Ensure spray area is clean and free of dust that could be
blown onto newly sprayed surfaces.
u
Cover any areas not intended to be sprayed.
u
Always spray from a minimum of 25mm to a maximum of
355mm (fig. L).
u
A commonly used method for spraying a large surface
is the “crisscross” pattern. This is done by spraying in
horizontal strips and then crossing over these strips with
vertical strips.
u
To get an even spray distribution, always keep your arm at
the same distance (fig. L) from the surface you are spray-
ing and avoid moving your wrist (fig. M).
