TECHNICAL DATA
EXTENSION CORD
When using an extension cord, be sure to use
one heavy enough to carry the current your
product will draw. An undersized cord will cause
a drop in line voltage resulting in loss of power
and overheating.
If an extension cord is to be used outdoors,
it must be marked with the suffix W-A after the
cord type designation. For example, a
designation of SJTW-A would indicate that
the cord would be appropriate for outdoor
use.

MATERIAL PREPARATION
Liquid material preparation Tip:
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 during pouring, mixing, and viscosity
testing of materials to be sprayed 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 starting. When thinning, use the
proper liquid thinner recommended on the container
by the material Manufacturer.
Warning! Do not use materials with a
flashpoint below than 21°C (70°F).
A viscosity test cup is provided to determine the
“runout time” of the material being used.
1. Before measuring for the proper viscosity,
stir the material thoroughly.
2. Dip the viscosity cup into the material
being sprayed and fill the cup completely.
3. With the cup held over the material container,
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 cup (100 seconds or less).
This is the “runout time”. Refer to the thinning
table below for information on the thinning
required for different materials. If material needs
thinning, add the appropriate liquid thinning
material recommended by the manufacturer.
Thinning table
Note: 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 within100 seconds. The operator should
consider the type of application and final location
of the project when spraying a material that
requires more than 100 seconds to run through
the viscosity cup.
OPERATION INSTRUCTION
Preparation tips
Always stir and strain the material thoroughly
before use. If need, please use the included
paper filter to filter out the impurities.
With any spraying job you should always ensure
that you have properly prepared the surface to
get the best finish. That is, all surface are free
from dust, dirt, rust and grease. Lightly pressure
wash decks or exterior surfaces and ensure that
they are dry before spraying.
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

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.
Before starting have gloves, paper towels, rags
etc. available for unexpected spills.
Filing the Canister
1. Unscrew the Canister. Stand the canister on a
smooth and horizontal surface.
2. Pour the properly thinned and strained
material to be sprayed into the canister.
3. Clean any residual liquid from the threads or
sides of the canister and sprayer.
4. Starting the threads evenly, screw the lid,
completely onto the top fill canister. Check
the lidtomake sure it is threaded on
squarely and completely before picking up
the sprayer.
Adjust Spray Pattern
The spray pattern shape is adjusted by turning
the ears of the air cap to either the vertical,
horizontal, or diagonal position. The position of
the air cap and the corresponding spray pattern
shape are shown below.
Material Flow Adjustment
Set the material volume by turning the regulator
on the trigger of the spray gun.
Turn to “+” mark direction increase the flow of
liquid and turn to “-“ direction decrease the flow of
liquid.
For thicker materials, it is recommended that you
start with the highest material flow setting and
then gradually decrease the flow to suit your
particular spraying needs.
For thinner materials, it is recommended that you
start with a low material flow setting and then
gradually increase the flow to suit your particular
spraying needs.
Always test the spray pattern on scrap cardboard
or similar material first, Begin with flow control
knob on highest flow setting. If less flow is
desired, dial the flow control knob to decrease the
flow of liquid.
Heavier, thicker material should be sprayed with
the flow control knob on high flow setting.
Thinner material should be sprayed with the flow
control knob on low flow setting.
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
The spray area must be clean and free of dust in
order to avoid blowing dust onto your freshly
sprayed surface.
Nozzle size pickup
Select right size of nozzle base upon the material
you are going to use and the surface targeting
finishing. The small size of nozzle reflected to
finer coating. Dilute material if needed for better
quality of the coating

HOW TO SPRAY PROPERLY
Position the spray gun perpendicular to and 2 or
more inches from the spray surface, depending on
the spray pattern size desired
Spray parallel to the surface with smooth passes
at a consistent speed as shown below. Doing this
will 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.
Keep stroke smooth and at an even speed
Always spray area from a minimum of 50mm (2
inches) to a maximum of 300mm (12 inches).To
get an even spray distribution. Always keep your
arm at the same distance from the surface you are
spraying and avoid flex wrist while spraying
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.
Light coat Heavy coat light coat
When you quit spraying for any length of time, turn
the power unit OFF and place the spray gun into
the built-in dock on the power unit.
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.
Avoid spraying too heavily in any one area. Several
lighter coats are better than one heavy coat which
can lead to running and dripping. Remember that
the flow control knob regulates the amount of liquid
that can be sprayed. If runs or drips do occur, have
a dry paint brush on hand to smooth them out.
CLEAN AND MAINTENANCE
Before you begin:
When cleaning, use the appropriate cleaning
solution (warm, soapy water for water-based
material like latex; mineral sprits for oil-based
material)
Special cleanup instruction for use with
flammable solvents (must have a flashpoint
above 70°F (21°C)
• Always flush spray gunoutside
• Area must be free of flammable vapors
