2. Connecting Your Air Source
With the right size air source for your project selected, it’s time to get the Katana Plus connected
to the compressor so you can start spraying! You’ll need the following:
Thread sealant tape (A) prevents
air leaks. Wrap 2 inches of tape
clockwise around air inlet of
spray gun. Be sure the tape is
flat, not bunched, and pulled
just slightly taught.
Tighten your quick-disconnect
adaptor (B) snug onto the
spray gun’s air inlet using an
adjustable crescent wrench (C).
Firmly press the quick-disconnect
of the air hose (D) onto the
quick-disconnect adaptor (B)
you attached to the spray gun.

PRE-OPERATION SETUP
It is optimal to supply the spray gun with dry air. Use of a moisture trap or filter is recommended.
Before first use, flush spray gun by slightly filling cup and spraying an appropriate cleaner
until empty.
Be sure gravity cup is firmly attached to the spray gun body.

1. Sizing An Appropriate Air Compressor
A spray gun’s magic happens in the air cap. An air cap has a required amount of air volume and air
force needed to atomize a liquid correctly and eciently.
The Katana Plus’s air cap requires a minimum volume of 9.9 CFM (Cubic Feet per Minute) with an
air force anywhere between 10–30 PSI (Pounds per Square Inch). All this jargon can be confusing,
so we’ve included this helpful table to make things a little clearer.

4. Dial It In
Next, you’ll notice 2 round adjusting knobs on the rear of the spray gun; the top is your pattern
adjustment knob and the next one down your fluid adjustment knob.
To start, tighten both knobs by turning clockwise until they stop. Then, loosen both by turning
counter-clockwise 4 FULL rotations. Both adjusters are now considered to be wide open.
3. Setting Your Air Pressure
A. Wide Open Pattern Adjusting Knob
Sprays a large, 6–8 inch fan (oval) pattern ideal for covering
large areas. Tightening (clockwise) will reduce the pattern to
a round, directional pattern for smaller areas. Make minor
adjustments and test to find the right size.
B. Wide Open Fluid Adjusting Knob
Provides maximum amount of fluid output through the spray
gun, ideal for larger surfaces. Tightening (clockwise) will
reduce the fluid flow, spraying less material for smaller spaces.
Note: You can change fan pattern from vertical to horizontal by loosening (counter-clockwise)
the air cap ring, rotating the air cap 90° and re-tightening the air cap ring.
Next, you'll want to set the appropriate pressure.
First, turn the compressor on.
Pull the Katana Plus trigger slowly until air
begins to blow. While air is exiting the spray
gun, use the regulator on the compressor to
set your pressure (10-20 PSI). Turn clockwise
to increase and counter-clockwise to
decrease air pressure.
Depending on your spray material, 10–20 PSI is
an ideal working pressure range for your spray
gun. We recommend spray gun at 20 PSI for
soft atomization and minimal overspray.

2. Prep Your Paint
You must always thin using the same substance found in the base of your material. Water for water-
based paints or white spirit for oil-based sealers for instance. If in doubt, check the label or contact
the material manufacturer to confirm proper thinning for use in a spray gun.
To thin, start with diluting the material using the appropriate substance by 10%. To do this, simply block
the hole of the viscosity cup and fill with your thinning agent, as the viscosity cup holds 1/10 of a liter.
Add the thinning agent to your liter of material, stir well to combineand re-test. If it needs further
thinning, add 5% more (about half a viscosity cup) of the thinning agent and repeat the above. Continue
to dilute in 5% increments and re-test until the desired viscosity (20 to 30 seconds) is achieved.
1. Prep Your Surface
Now that your surface is prepped and ready to paint, make sure your spray material is at the right
consistency before you make your first pass. We’ve included a handy viscosity cup to help you out.
Pour 1 liter of paint into the container and dip the viscosity cup fully into the material so it is
completely filled. (We recommend using a container that will hold at least 1 liter of paint.)
Raise the viscosity cup above and fully out of the material so the stream leaving the cup is visible
and start a timer or stopwatch. Stop the timer or stopwatch the instant you notice a break in the
stream (not waiting for the cup to completely empty) and note the result.
The Katana Plus will spray best when a noticeable break in the stream appears between 20 and 30
seconds after you start. If your result is at 40 seconds or higher you may need to thin the material.
The first step is always to prepare your surface for paint.
Scu the surface using fine grit sandpaper or sanding sponge. Clean the surface using isopropyl
alcohol or another household degreasing cleaner and a lint free cloth.Allow the surface to dry
completely before applying any spray material.
With your cup securely attached to the spray gun, pour your paint
into the cup through one of the provided paint strainers. Once
filled, be sure to tighten the cup lid and remove the breather cap
to maintain consistent paint flow and spray.
IMPORTANT: Spray gun passageways and nozzles are very small,
narrow and can clog easily from dried or used (contaminated)
spray material. We highly recommend pouring your material into
the Katana Plus's paint cup through a strainer. Included are 5
paint strainers to get you started.

4. Test Your Spray
If excessive paint is
floating around in the
air, you may need to
decrease pressure on
your compressor, or
the spray gun is too far
away from your surface
(more than 6 inches).
No more adjusting
needed to start
spraying!
If your paint seems
to be spraying out
in a spatter-type
texture, you may
need to increase
the air pressure on
your compressor.
If your paint seems
to be consistently
running, you may need
to move your spray
hand a little faster or
the spray gun is too
close to the surface
(closer than 6 inches).
5. One Coat at a Time
Remember to do test sprays on something like paper
or cardboard before moving over to your project so
you can get it right the first time!
To test your spray, pick up the spray gun with your
dominant hand. Grip the handle loosely while resting
your index and middle finger on the trigger. The trigger
should always be parallel to the surface, with your
thumb pointing in the direction you’re spraying. Always
keep the nozzle about 6 to 8 inches from the surface.
Pull the trigger to release air and paint in one spot to
see if your spray gun and spray material are adjusted
properly. You may need to adjust your spray pattern or
fluid output with the knobs on the back of the spray
gun if you don’t get a good test spray.
When spraying liquid, always apply in one
consistent direction (from left to right, for
instance).Hold the spray gun with the
trigger parallel to the surface and the nozzle
6 inches away. Start spraying just outside
of the area you want to coat and move the
gun across the length of the surface.
When applying the next pass of material,
overlap the first section by about 50%
to ensure even coverage.
Continue this practice until the area is fully
coated. Depending on the material used,
you may need multiple passes to achieve
full coverage of the area.

REMEMBER
• ALWAYS brush the air cap o periodically using the cleaning brush throughout the
painting process to keep it free of paint build up.
• NEVER remove the needle while there is paint in your cup as doing so will allow paint to
leak from the spray gun.
• ALWAYS have fun with it!
6. Wait
It is important to follow material’s manufacturer guidelines on dry times and applying additional
coats. Apply additional coats as directed until desired finish is achieved.
Just like any tool, you want to get familiar and comfortable with your spray gun. Once you do,
you’ll find this tool an essential addition to your arsenal and a great way to save time and materi-
als on all kinds of projects while getting a beautiful, smooth finish.

The best thing you can do for your spray gun is keep it clean. Dried paint build up can lead to
issues later, so take the time to make sure the material you used is fully expressed from the spray
gun each time you’re finished spraying.
1. When finished, pour out the remaining paint material
from your cup. Refer to paint manufacturer for storage
and re-usage information. Be sure to check your local
regulations for paint disposal and recycle or donate
when you can!
2. Add the manufacturer recommended cleaner or
thinning agent into the cup and use a clean cloth
to wipe the cup out well.
3. With your finger o the trigger, use your cleaning
brush and some of the same cleaner to brush o the
front cap on the spray gun. Any holes should be clean
and clear of paint material.
4. With the spray gun connected to the air source and in
a well-ventilated area, add a generous amount of cleaner
into the cup. Pull back on the trigger to spray the cleaner
through. Repeat this step until the spray gun is spraying
clear liquid. NEVER spray any material near sparks or
open flames.

After each use and prior to any cleaning or maintenance you MUST follow the below guidelines:
5. You MUST release all pressure from spray gun before continuing.
a. If using a quick-disconnect, slide the release on the hose fitting toward the
compressor to disconnect.
b. If no quick-disconnect is being used, switch compressor to o position. Depress the
trigger on the spray gun and hold until all air is drained from the tank. This may take
several minutes if using a larger capacity air tank.
