Please read these instructions carefully before using the equipment
ELECTRICAL
The turbine is powered by a 3-stage, or 4-stage (depending on the model)
single speed, bypass, air turbine. This turbine must be connected to the
correct voltage. Please check the label on the base of the turbine for
voltage rating.

For your safety and protection, we have equipped your Fuji turbine with a
three pronged grounding plug on the service cord. This must be plugged
into a properly grounded 3-pronged receptacle.
WARNING:
THE TURBINE MUST NOT BE USED IN AN AREA CONTAMINATED BY VOLATILE
OR FLAMMABLE MATERIALS SINCE SPARKING CAN BE
EXPECTED IN THE NORMAL OPERATION OF THE MOTOR. THIS COULD
IGNITE THE CONTAMINANTS CAUSING A DANGEROUS EXPLOSION. KEEP
THE TURBINE AT LEAST 18 FEET (6 METERS) AWAY FROM THE SPRAYING
AREA. FOR HEALTH REASONS, ALWAYS WEAR A RESPIRATOR.
FILTER(S)
The Q-Series turbines use just one large filter. The turbine case does not
have to be taken apart to replace the filter. To remove, simply turn the
turbine on its side and pull the filter out. Wash in solvent and dry before
replacing. The filters are a friction fit. When replacing, push the filter in by
hand and finish up by using a screwdriver through the square holes to
lever the filter into position. The filter must fill the entire filter enclosure and
always be FLUSH with the base of the turbine case.The Super Model uses
2 filters, one fine and one coarse. Looking from the front of the turbine
please insert the fine filter to the left side (near the ‘F’ of Fuji) and the
coarse to the right side. It is important to keep the turbine as far away as
possible from the spraying area (and workshop dust). If the filters become
badly clogged, cooling air will be restricted - this may cause serious
damage to the motor.
HOSE CONNECTION
Connect the end of the hose with the female connector to the turbine air outlet.
To connect the hose to the gun, slide back the quick-connect collar and push
this onto the hose connector (Part .2029). To disconnect from the gun, slide
back the collar to release the quick-connect from the hose connector. ALWAYS
TURN OFF THE TURBINE BEFORE DISCONNECTING THE GUN FROM THE
HOSE - THEN OPEN THE CUP TO RELEASE THE PRESSURE.
1
Please do not leave the cup under pressure as this causes paint to travel
up the pressurizing tube (Part. 2024) and into the check valve.
CHANGING THE SHAPE OF THE SPRAY PATTERN
On a warm day, the hot air passing through the gun handle may make it
uncomfortable to hold. The Fuji spray gun has two air intakes. Switching
the hose connector (Part. 2029) with the blanking screw (Part. 2011) will
enable you to connect the hose to the upper air intake. The hot air will travel
along the top of the gun leaving the handle more comfortable to hold. You
may want to pass the hose over your shoulder.
AIR CONTROL VALVE
The air control valve provides you with a means of controlling the air flow
through the gun. It is far superior to having a variable speed switch on the
turbine because you will often want to adjust the air without having to walk
over to the turbine. Plus, it does not cause overheating of the motor which
happens when the speed of the turbine motor is reduced. This is because
turning down the speed,also reduces speed and efficiency of the cooling
fan. There is one thing to remember about the air control valve - it is the
‘last in the chain’ of operations after 1) Thinning the paint 2) Adjusting the
shape and size of the spray pattern 3) Adjusting the flow of paint through
the gun. After performing these operations, you should spray a few
passes onto a scrap piece of plywood or cardboard. This will allow you to
determine if the paint (generic word for any type of coating) levels nicely. If
there is ‘orange-peel’ then you must thin the product more. It is no use to
turn down the air to remedy orange-peel. Once the gun is producing a
perfect finish with full air, you may then experiment with turning the air down
until bounceback is reduced to a mininum. However, if orange-peel results,
you have no option but to turn the air up again a slight amount. With heavier
paints (such as latex) spraying should be done with the valve fully open (or
even removed). When excessive ‘blowback’ or overspray is a problem, turn
the lever to reduce the amount of air. To prevent runs when reducing the air,
you may have to reduce the amount of material (fluid adjusting screw Part
2019). The spray-gun is a ‘bleeder’ type gun, this means that air flows
constantly through the gun. The air control valve has been modified so that
the air cannot be shut-off completely as this could cause overheating and
shorten the life of the motor.
Turn the air nozzle until it clicks into the horizontal position. This setting produces a vertical pattern useful for spraying from side to side. Set the nozzle
in a vertical position. This setting produces a horizontal pattern, useful for
spraying up and down. Now try setting the nozzle at a 45º angle. This setting
produces a round pattern useful for spraying thinner objects. Remember to
turn down the amount of paint when you switch to a smaller round pattern,
otherwise you will find that there will be too much paint concentrated in one
spot. To test, try turning the fluid adjusting screw (part. 2019) clockwise
until you cannot pull the trigger. Then unscrew it a little until a small amount
of paint material comes out of the jet when you depress the trigger. This
results in a small circular pattern. If you continue to depress the trigger and
move along your workpiece you will get a fine line. From 6” away this will give
you a pattern about 1” - 2” in diameter. This would be handy for spraying thin
spindles in a chair for instance. Then place the nozzle to where it almost
touches the test board and the pattern becomes extremely small - similar to
an airbrush. Try writing your name with the gun. If you get runs then you will
have to adjust the fluid adjusting screw again at the back of the gun. This
type of technique is handy for repairs and touch-up. To obtain more coverage with a fuller spray, unscrew the fluid adjusting screw. Experimenting
like this enables you to become familiar with your Fuji spraygun.
CHANGING THE SIZE OF THE SPRAY PATTERN
GETTING STARTED
Your Fuji Spraygun has been adjusted at the factory and is ready for
spraying. To clean out any impurities that may have accumulated during
assembly or shipping, we recommend spraying a small quantity of clean
paint thinner
through the gun. Before tackling any serious spraying, experiment with the
gun on a scrap piece of wood or cardboard until you become familiar with
all the controls.
If you are familiar with high pressure sprayguns, please read this section
very carefully. The method we use to adjust the size of the spray pattern is
very different to what you are used to. The principal is simple... The air
nozzle is backed by a spring and is ‘floating’.
Winding the spraycap IN results in a LARGER SPRAY PATTERN.
Winding the spray cap OUT will result in a SMALLER SPRAY PATTERN.
Always start with the air control valve fully open.

The standard position is shown in Fig A. The tip of the fluid jet should be flush
with the nozzle. Winding out the spraycap (counter-clockwise) causes more air
to pass through the center hole and less to the horns. The result is a smaller
pattern. (Fig B). When the spraycap is screwed in, air is cut off from the center
hole in the nozzle. This redirects air to the horns resulting in a wider fan pattern.
(Fig C).
emergencies. Any paint in the pressure tube, or the nipples the tube is
attached to, will cause reduced amounts of paint through the gun. This is
because the pressure is being restricted through the nipples by the paint
blockage. The symptom will be little or no paint and the reason will always
be the nipples, tube or check valve being clogged or semi-clogged with
dried paint.
For more details on this subject, please see the section on Spraygun
Problems later on in this User Manual.
ACTUAL SPRAYING TECHNIQUES.
The spraygun should be held perpendicular to the surface at all times.
HOLD THE GUN NO MORE THAN 8” (20cm) AWAY FROM THE SURFACE
TO BE PAINTED.

CORRECT METHOD
CAUTION: DO NOT TURN THE SPRAYCAP ALL THE WAY IN (FIG. C). THIS
BLOCKS AIR OFF COMPLETELY FROM THE CENTER HOLE AND RESULTS
IN A VERY LARGE SPRAY PATTERN WITH TOO MUCH OVERSPRAY.
HOW TO PREVENT PAINT ENTERING THE GUN
A few very simple rules must be followed in order to keep the gun clear of paint.
No paint or fluids should ever be in the gun body at any time.
Upon stopping spraying for any reason, turn off the turbine and allow it to die
down. The hose must never be disconnected when the turbine is running. To
do this would instantly release the pressure out of the gun body yet there would
still be pressure in the cup. This pressure is enough to force paint up the
pressure tube into the spraygun. Only air should pass down the pressure
tube. No paint will travel up the tube if the rules are followed. Once the turbine
has come to a full stop, gently open the lid of the cup to release the pressure
inside. If you intend to leave the spraygun for a while, you don’t have to drop off
the cup, simply slide the lever over to allow the pressure to escape and close it
again. Then hang the up the gun - use any type of hook for this. Do not stand
the gun on a bench or even the floor because it will always be prone to falling
over which could damage the spraygun and cause paint to flow up the pressure tube and into the spraygun.
Start moving the spraygun in the direction you want to spray and press the
trigger. Between each successive pass, overlap by about a quarter.
INCORRECT METHOD
If paint does enter into the pressure tube, stop spraying the first chance you get
and turn off the turbine. When it has stopped completely, open the cup to
release the pressure. Remove the pressure tube/valve and soak it in thinner
for a while. Then shake vigorously back and forth to clean out the check valve.
Finally, test by blowing through the tube. You should be able to blow one way
but not the other. It is advisable to have a few pressure tubes on hand for

GUIDE TO NEEDLE, NOZZLE, AND JET SELECTION
A WORD ABOUT LATEX
The fluid jet and needle MUST always match exactly. However, the
spraycap/air nozzle may be one size up or down from the norm. The sizes
No.3 and 4 setups are both ideal for all fine finishing. 4 different setups
are available as accessories. Generally speaking, the quality of atomization and finish suffers as you go to the larger size setups (No.5 and 6).
Please note that the chart offers you a starting point only as to the setup
size to be used. The best way to decide is by experimentation. If you are
using the No. 3 setup and wish to spray faster, wetter then switch to No. 4.
Most latex paints do not spray well or flow out nicely but by following a
few general rules, a professional finish can be achieved. Please do not
confuse latex with the newer water-based coatings which spray beautifully. For work such as cabinetry or trim, our equipment can be used
successfully with latex paint. The latex will have to be thinned with
WATER - approximately 20-30% depending on the brand of paint.
and preferably an additive used to give it more sprayability. One product
available is FLOETROL from the FLOOD Company in Ohio. In the USA

Although it is possible to use our equipment for house painting (walls),
and many end users do, we feel that an airless gun or power roller is
better suited to that kind of job. However, if you decide to do this kind of
work, you will need at least the #5 setup.
VISCOSITY
Follow the viscosity guide chart. You will eventually learn to thin the
material by experience. Traditionally, lacquers were thinned 50/50 even
for high pressure spraying but this much thinning is not neccessary.
However, coatings manufacturers are reformulating constantly so it is
always advisable to check with them. Thinning a product excessively
causes more overspray as well as runs. Stringent air quality controls in
some geographic locations may prohibit reducing by more than 30%.
Remember, when you buy a can of paint, lacquer, polyurethane, varnish
etc. over the counter, it will be formulated for brushing. That means, it will
be too viscous (thick) and will require thinning to spray successfully.
When spraying with a conventional system, it is estimated that up to 90%
of what you spray evaporates, mists and floats about in the surrounding
air. Most conventional compressor type systems atomize the material at
45 - 60 PSI with very low CFM. Please keep in mind that this is a generalization - there are many variables.
The Fuji Turbine System atomizes the material with a constant high
volume of air flow. Unrestricted, turbines produce 100 CFM at low
pressures (5 - 8 PSI). The low pressure allows the material being
sprayed to be laid on gently and not blasted on. Lower velocity translates
to less bounce-back and less overspray. Don’t forget that once you have
adjusted the viscosity and size of the spray pattern, you must then adjust
how much paint flows through the gun. Then you should try reducing the
air pressure at the air control valve to reduce bounceback and overspray.

VISCOSITY GUIDE
To test the viscosity of the paint material, fill the viscosity cup to the brim
and time how long it takes for the liquid to empty out through the hole. We
recommend you experiment to find the ideal viscosity for your application
and record the information for the next time.
The chart below is an approximate guide to thinning. Note that the viscosity cup has a hole in the bottom. To check viscosity, dip the cup into the
thinned paint and time how long it takes for the paint to run out of the cup.

Remember, as a general rule, most ‘paints’ you purchase over the counter
were formulated for using with a brush and are too thick to spray successfully without thinning. This includes all lacquers, enamels, oil-based
paints, latex etc. There is usually no mention of thinning for spraying so
you will have to experiment. We suggest around 25% to begin with but this
may contravene the air quality control rules for your location, so please
check this by calling the paint manufacturer. The solvent used for thinning
is usually the solvent mentioned on the can in the instructions for ‘cleaning
the brushes’. However, if you are unsure, please check with the coatings
manufacturer.
HVLP spraying is more friendly to the environment than most methods of
spraying. It reduces appreciably the amount of unnecessary misting and
fogging (overspray) associated with high-pressure spraying. Spraying with
Nitrocellulose lacquer can be hazardous. The lacquer, fumes and
overspray are toxic, flammable and explosive. If spraying must be done
inside an enclosed area, ventilate well. Spray close to an open window or
door and situate a fan to draw out the fumes (an explosion-proof motor
may be necessary). PLEASE CHECK WITH THE LOCAL AUTHORITY
HAVING JURISDICTION IN THIS MATTER.
If this type of cleaning is done while the paint is still wet in the gun, then
this should be all that is neccessary to keep the gun clean enough for next
time. Do not leave liquids in the cup. PLEASE DO NOT USE A WIRE
BRUSH OR ANYTHING METAL TO CLEAN THE GUN OR CUP AS THIS
WILL CAUSE DAMAGE.
Some companies manufacture what is called a ‘gun and brush cleaner’
liquid made specifically for cleaning the spraygun/parts. Please check with
your paint supplier.
CAUTION: Never soak the complete spraygun in solvent as this removes
the grease from the parts and distributes thinned paints throughout the air
passages. It may however, be necessary sometimes to soak the front
barrel in thinner. Please remove the nylon spraycap before soaking.
PERIODIC STRIP DOWN CLEANING
Tools required: 3/4" wrench, adjustable wrench, needle nosed pliers, jet
wrench.
If the spraygun is cleaned by flushing through solvents as described
above, it should not be necessary to strip down the whole spraygun.
However, to completely strip down the spraygun, first remove the fluid
adjusting screw and spring. Pull on the trigger and remove needle (use
needle nosed pliers to gently pull it out). Remove spraycap then the plate
spring. Use the special jet wrench to remove the fluid jet. Loosen the fluid
coupler jamb nut then turn out the fluid coupler. At this stage you can
remove the gun block. Should the block be tight, screw the fluid coupler
into the front hole of the block (in place of the fluid jet) and turn out the
block. Soak these parts in solvent and clean with a soft bristle brush.
DO NOT use metal objects to clean parts. DO NOT dissassemble the cup
assembly - your cup has been sealed at the factory to prevent leakage.
To reassemble, first oil or grease all moving and threaded parts. Replace
gun block and all parts in reverse order. CAUTION: Do not store the gun
with the cup clamped down hard as this will cause the gasket to flatten out.
Do not lay the gun down on its side with liquid material in it.
CLEANING
PRESSURE POT USE
To clean the gun after each use, empty all paint from the cup. Use a solvent
soaked rag to clean the residue in the cup and on the metal fluid tube.
Then, spray some clean solvent through the gun into a clean rag. Repeat if
neccessary until the inside of the gunblock, metal fluid tube etc. is clean.
Use the wet rag to wipe off the air nozzle, and tip of the jet. Don’t forget to
open the cup to release the pressure so the spraygun can be left for a long
period of time.
To use the gun with a pressure pot, remove the cup and the pressurizing
tube. Connect your material line to the fluid coupler on the gun. Because
you are using air from the turbine, you must block off the air that would
normally go from the pressure pot to the gun. A cap must be placed over
the nipple to prevent air escaping - this plastic cap - Part. 2023B is
available from Fuji. The Fuji spray gun has two air intakes - attach the
turbine hose to either of these intakes in the regular way. A COMPRESSOR
IS NEEDED TO PRESSURIZE THE POT.

Set the compressor to between 6-8 PSI. This is enough to push the paint
material up to the gun. For spraying at greater heights (over 8 feet), more
fluid pressure may be necessary. The fluid pressure should never be set at
more than 20 PSI. If you find that higher pressure is needed we advise you
to check the fluid tube for any paint blockage.
FINISH PROBLEMS
ORANGE PEEL - If the finish is rough and resembles orange peel then the
material is too thick. It will not atomize properly and the surface will be
spotty. To correct this, make sure that the next coat applied is full and wet.
If severe, add a retarder. This will slow the drying time allowing the material
to flow out. NOTE: With the newer water-based materials ‘orange peel’ is
usually a result of spraying on too thick a coat. Try spraying extremely
THIN, but WET coats. With most other coatings, orange peel is caused by
material being too thick or not enough atomizing power. This is why we
suggest leaving the air control valve fully open when experimenting with a
new coating material, otherwise it will cause confusion. If the the air control
valve is fully open (or perhaps removed for Latex spraying) then orange
peel can only be one cause - the material is too thick. Use of a retarder is
recommended with nitrocellulose lacquer (lacquer retarder), Penetrol for
oil-based paints and as mentioned previously, Floetrol for latex house
paints.
GRITTY FINISH - If the material is too thin, it is likely to run or be overatomized producing a rough gritty finish.
SPRAYGUN PROBLEMS
NO PAINT (OR VERY LITTLE PAINT)
THIS IS THE MOST COMMON PROBLEM ENCOUNTERED. The air passing
through the plastic tube to pressurize the cup is blocked. To locate where
the air blockage is, open the cup. Remove the pressure tube from the
nipple under the barrel only. Blow down the tube - it should feel like
blowing freely through a drinking straw. If it’s clear, it’s ok. If there is
resistance, either the checkvalve or the nipple on the cup lid is clogged or
semi-clogged. Clean at both these points A pipe cleaner can be used for
cleaning the hole in the nipple. Replace the pressure tube/valve if
neccessary. Then, connect the gun to the hose and turn on the turbine.
Feel the air passing through the nipple under the barrel - it should feel like
someone is blowing through a straw. If not much air pressure is evident,
clean this nipple too or even remove it to get behind it. Once this nipple is
clear, re-attach the pressure tube and test with thinner or water. If air can
pass freely through the nipple under the barrel, through the checkvalve and
into the cup, the gun will spray perfectly (assuming that the paint is thinned
properly) Please see ‘How to prevent paint entering the gun’ - Page 4.

The pressurizing tube and/or nipples are blocked with paint.
The cup is not tightened down sufficiently by the quick-release
lever or the cup gasket is worn and leaking air.
The cup is empty
The metal fluid tube is blocked with paint - very rare.
BLUSHING - Blushing is the common term used when the finish looks
cloudy (sometimes also called blooming). It is caused by moisture and is
especially a problem when operating high pressure spray equipment. The
moisture comes from the compressor. This problem does not usually
occur when using the Fuji turbine. The reason is that the air from the
turbine is warm, dry and uncontaminated. However, it is possible on very
humid days to encounter slight blushing. Using a retarder will often allow
moisture to escape preventing the milky look.
UNEVEN SPRAY PATTERN
FISH EYES - If you are refinishing furniture or pianos, fish eyes could
become a problem. The cause is usually silicone from polish which has
been liquified by the paint stripper that has now soaked into the bare wood.
This silicone prevents the lacquer from adhering to the wood. One way to
sometimes correct this is to seal in the silicone by misting on two or three
light coats of lacquer. Then spray on a regular wet coat. We do not recommend the use of ‘Fish-Eye Drops’ which is essentially liquid silicone.
Silicone will only contaminate the gun even further. Anything that comes
into contact with the silicone becomes contaminated - such as; rags,
aprons, bench tops, gloves.
If paint material comes out of the fluid jet without pulling back the trigger...

One of the holes in the air nozzle may be blocked. Or, the paint could be
dirty and is partially blocking the fluid jet. Remove the air nozzle and clean
by soaking in solvent and using a soft bristle brush or rag. NEVER use
metal objects to clean holes in the spray cap nozzle.
LEAKAGE

The working length of the needle is too short - see Needle
Assembly Too Short. This is the most common reason.
The needle is not seating in the fluid jet properly

Foreign matter could be trapped between the needle and the jet.
The needle or fluid jet could be damaged or worn.

INSTALLING A NEEDLE ASSEMBLY
ADJUSTING THE NEEDLE SEAL (PACKING)
Like other spraygun manufacturers, we use ‘stock’ stainless steel rod
for the needle. This rod can differ in diameter slightly with each run. This
means that when you change say, a #3 for a #4 needle. One could be
slightly oversized diameter and one slightly undersized. This
neccessitates adjusting the needle seal.
The needle seal bushing (packing) must be tight enough to prevent any
leakage of paint material into the gun. It should however, allow the
needle to glide smoothly through it. If this bushing is too loose often a
‘pulsating’ of the spray pattern will be seen. Insert the needle seal
adjusting tool (with teeth pointing downwards) over the needle. This is
the tubular-shaped tool that comes with the complete Fuji system.
Locate the slots in the needle seal nut and tighten the needle seal while
continually pulling the trigger. (If the slots are clogged with paint, use a
sharp screwdriver to clean out the slots). Once the needle is grabbed by
the seal, back off the screw a very slight amount. The needle seal is
adjusted perfectly just short of the point where the needle sticks. Another
guide is to grasp the end of the needle and shake it firmly but gently from
side to side - there should be no play - but the needle should still slide
smoothly without sticking when the trigger is pulled. The needle seal
should never need replacing.
NEEDLE ASSEMBLY TOO SHORT
If the needle is not reaching far enough into the fluid jet, remove it. To
adjust length ‘A’ first loosen the needle locking nut, then turn the needle
drum counter-clockwise about 1/2 turn. Carefully retighten the locking
nut. Remember, even 1/2 turn of the needle drum lengthens the working
length of the needle by quite a large amount. A good tip is to only adjust it
1/2 turn maximum and then test. If this is not enough then simply repeat
the procedure. When the needle is the correct length, there will be no
leakage of paint from the jet when the trigger is not depressed. The
trigger action should be smooth and free.
Tools required: Needle-nosed pliers, Jet wrench, Needle seal adjuster,
3/8" and 5/16" open end wrench.
Remove the fluid adjusting screw and spring. Pull the trigger back to
remove the needle. Use needle nose pliers to grab the needle drum at the
rear of the needle. Fuji supplies the needle assembly complete with the
locking nut and drum. Carefully insert the needle through the hole in the
gun block. It may be fairly tight due to the friction of the teflon needle seal.
Insert the spring and screw in the fluid adjusting screw. Before installing
the fluid jet, see ADJUSTING THE NEEDLE SEAL and then if neccessary
see NEEDLE ASSEMBLY TOO SHORT.

NEEDLE ASSEMBLY TOO LONG
If the needle assembly is lengthened too much, the trigger pull distance
will feel too short. To remedy, reverse the above procedure.
