SAVE THESE INSTRUCTIONS: To reduce the
risks of fire or explosion, electrical shock and
the injury to persons, read and understand all
instructions included in this manual. Be familiar
with the controls and the proper usage of the
equipment.
To avoid these risks, take the following
preventions:
►Exhaust and fresh air introduction must be
provided to keep the air within the spray area
►Avoid all ignition sources such as static
electricity sparks, open flames, pilot lights, hot
objects, lit tobacco products, and sparks from
connecting and disconnecting power cords or
working light switches.
►Fire extinguisher equipment shall be present
and working.
►Keep area clean and free of paint or solvent
►Follow the material and solvent manufacturer’s
safety precautions and warnings.
►Do not spray flammable or combustible
materials near an open flame or sources of
ignition such as lit tobacco products, motors, and
electrical equipment.
►Know the contents of the spray materials
and their cleaning solvents. Read all Material
Safety Data Sheets (MSDS) and container
labels provided with the spray materials and
solvents. Follow the spray material and solvent
manufacturer’s safety instructions.

Wa rning! Ex p losion ha z ard due to
incompatible materials. Severe injury or
property damage can occur.
To avoid these risks, take the following
preventions:
► Do not use bleach.
►Do not use halogen a ted hydrocarb o n
solvents such as methylene chloride and 1,1,1
- trichloroethane. They are not compatible with
aluminum and may cause an explosion. If you

Liquid material preparation (Fig. E1 and E2)
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 rag during pouring , mixing , and
testing of materials to be sprayed to

thinning, use the proper liquid thinner
recommended on the container by the material
manufacturer..
Warning!: Do not use materials with a
A viscosity test cup is provided to determine the
“runout time” of the material being used.
►Before measuring for the proper viscosity, stir
the material thoroughly.
►Dip the viscosity cup into the material being
►With the cup held over the material container,
measure the amount of time it takes for the

information on the thinning required for different
materials.
►If material needs thinning, add the appropriate
liquid, thinning material recommended by the
manufacturer
►It is possible to spray latex paint with this
unit, however, the required thinning may exceed
material manufacturer’s recommendation. Thin

►When using the tool outdoors, only use
extension cables intended for outdoor use. A
suitable rated extension cable of up to 30 M can

Use only a 3-blade grounding plug and a
3-slot receptacle that will accept the plug on the
product. Make sure your extension cord is in good
condition. 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
after the cord type designation. For example, a
designation of SJTW-A would indicate that the
cord would be appropriate for outdoor use. For

FILLING THE CANISTER (FIG. F)
►Check to make sure that the canister is
completely screwed onto the sprayer.
►Stand the sprayer firmly on a smooth and
horizontal surface
►Pour the properly thinned and strained
material to be sprayed into the canister (Fig. F).
►Clean any residual liquid from the threads or
sides of the canister and sprayer.
►Starting the threads evenly, screw the lid
completely onto the top of canister. Check the
lid to make sure it is threaded on squarely and
completely before picking up the sprayer.

accordingly.
PREPARATION TIPS
►Always stir and strain the material thoroughly
before use.
►With any spraying job you should always
ensure that you have properly prepared the
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 untouched.
► Skin that forms on the top of paint can clog the
sprayer. Remove skin before mixing. Strain with

FLOW CONTROL KNOB (Fig. I)
The flow control knob(#18) regul ates t he
amount of liquid that can be sprayed. Turning
the flow knob clockwise increases the flow of
liquid. Turning the knob counter anti-clockwise
Tip: Always test the spray pattern on scrap

flow is desired, dial the flow control knob anti-
thicker materials should be sprayed with the
flow control knob on high flow setting. Thinner
►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.
►Ensure surface to be sprayed is free of dust,
dirt, and grease.
►Ensure spray area is clean and free of dust
that could be blown onto newly sprayed surfaces.
► Cover any areas not intended to be sprayed.
►Always spray from a minimum of 50mm to a
maximum of 300mm (Fig. J).
►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 (Fig. L).
►To get an even spray distribution, always keep
your arm at the same distance (Fig. J) from the
surface you are spraying and avoid moving your
wrist (Fig. K).
►Maintain smooth and consistent speed which
will help avoid inconsistencies. Begin spraying
after the pass has begun and release trigger
before stopping the pass.
►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. Turning
the flow knob clockwise increases the flow
of liquid. Turning the knob counterclockwise
decreases the flow of liquid. If runs or drips do
occur, have a dry paint brush on hand to smooth
them out.
►Turn the power unit off and place the sprayer
in the built-in dock of the power unit when not
spraying for any length of time.

►Turn the power unit off, unplug the cord.
► Unscrew the canister from the sprayer.
►Remove the o-ring(#14), pickup tube(#15),
check valve (#16), and quick refill lid(#12) from
the sprayer. Clean the parts with the cleaning
brush in the appropriate cleaning solution (Fig. P).
Note: When removing the check valve, twist the
check valve clockwise and then pull it out.(Fig P

►Unscrew the tip collar (#4) and remove all
the parts of the spray nozzle(#3,#4,#5,#6,#7.#8)

Remove the spray tip(#9) from the sprayer ( Fig.
Q1). Clean all parts with the cleaning brush in the
appropriate cleaning solution (Fig. Q, Fig.Q1).
Be sure to clean around check valve with brush
(Fig. Q insert).
►If using water based material, clean the
sprayer by running water through pickup tube
inlet as shown in Fig. R. If using oil based
materials, clean pickup tube inlet with the
appropriate cleaning solution.
Repeat until sprayer is completely clean.
► Dry all parts thoroughly.
► Properly dispose of cleaning solution.
►Place a drop of household oil into the inside
of the sprayer from the hole for assembling the
spray tip (Fig. S).
